    ABSTRACT: AIMS: The aim of this single-site, randomized, controlled, double-blind, 3-arm parallel study was to determine the effectiveness of a prophylaxis paste containing 15% calcium sodium phosphosilicate (CSPS; NovaMin(®) ) with and without fluoride in reducing dentine hypersensitivity immediately after a single application and 28 days following dental scaling and root planing. MATERIALS & METHODS: Overall, 151 subjects were enrolled in this study. All subjects received a scaling and root planing procedure followed by a final prophylaxis step using one of three different prophylaxis pastes: Test-A (15% NovaMin(®) and NaF), Test-B (15% NovaMin(®) ) and a control. Dentine hypersensitivity was assessed by tactile stimulus (Yeaple Probe(®) ) and by air blast (Schiff scale) at baseline, immediately after and 28 days after a prophylaxis procedure. One hundred and forty-nine subjects completed the study. RESULTS: Subjects having received the test prophylaxis pastes showed statistically lower (anova, p < 0.05) dentine hypersensitivity compared with the control group immediately after the prophylaxis procedure (Yeaple Probe(®) : Test-A = 20.9 ± 12.6, Test-B = 22.7 ± 12.9, Control=11.2 ± 3.1; Schiff score: Test-A = 1.1 ± 0.6, Test-B = 1.1 ± 0.6, Control = 2.0 ± 0.7) and after 28 days (Yeaple probe: Test-A = 21.5 ± 11.9, Test-B = 20.6 ± 11.3, Control = 11.8 ± 6.0; Schiff score: Test-A = 1.0 ± 0.6, Test-B = 1.0 ± 0.6, Control = 2.0 ± 0.7). CONCLUSIONS: In conclusion, the single application of both fluoridated and non-fluoridated prophylaxis pastes containing 15% CSPS (NovaMin(®) ) provided a significant reduction of dentine hypersensitivity up to at least 28 days.

    ABSTRACT: Scaling and root planing (SRP) is the primary non-surgical treatment for periodontitis, but its effectiveness is limited. Consequently, various adjunctive therapies have been investigated to improve clinical outcome. This study evaluated the clinical effects of one SRP procedure alone or combined with local administration of hydrogen peroxide gel using customized trays for the treatment of subjects with chronic periodontitis over a period of six months. An examiner-blind clinical trial was conducted among 30 subjects with moderate to advanced periodontitis who were randomized to SRP alone or SRP combined with prescription custom-tray application (Perio Tray) of 1.7% hydrogen peroxide gel (Perio Gel) for a period of three months, then extended to six months. Following impressions for the test group, all subjects brushed twice daily with a regular dentifrice and toothbrush for a four-week acclimation phase to standardize oral conditions (while trays were fabricated) prior to initiating the treatment phase. SRP was performed three weeks after baseline, and clinical assessments, i.e., pocket probing depth (PPD) and bleeding index (BI), were conducted at baseline and after two, five, 13, and 26 weeks of peroxide gel applications. Clinical variables were compared by ANCOVA and paired t-tests after each treatment interval. A total of 13 test and 15 control subjects completed the original three-month trial, of whom 10 test and 13 control subjects finished the three-month extension. After two weeks of peroxide gel use prior to SRP, mean PPD for the test group significantly decreased from baseline by 0.21 mm and mean BI significantly dropped by 0.14; clinical parameters for the control group were unchanged. Two weeks following SRP, mean PPD significantly decreased from baseline by 0.65 mm for the test group and 0.17 mm for the control; mean BI significantly dropped by 0.17 for the test group and 0.05 for the control. Ten weeks following SRP, mean PPD decreases were 0.77 mm for the test group and 0.13 mm for the control, and mean BI reductions were 0.14 for the test group and 0.00 for the control. For subjects who completed the three-month extension (i.e., 23 weeks post-SRP), mean PPD decreases were 0.72 mm for the test group and 0.13 mm for the control, and mean BI reductions were 0.05 for the test group and 0.01 for the control. Analysis of deeper pockets (i.e., > 5 mm at baseline) showed the same relationship for PPD, but with larger differences between groups. For example, after two weeks of peroxide gel use prior to SRP, mean PPD decreased by 0.48 mm for the test group compared to 0.04 mm for the control. Two weeks after SRP, mean PPD decreased from baseline by 1.40 mm for the test group and 0.60 mm for the control, and 10 weeks after SRP by 1.57 mm for the test group and 0.58 mm for the control. After the extension (i.e., 23 weeks post-SRP), mean PPD changed from baseline by 1.50 mm for the test group and 0.55 mm for the control. With the exception of BI at 23 weeks post-SRP, all reductions cited above for the test group were statistically significantly different from the control group for both PPD and BI for all comparisons. When compared with SRP alone, clinical improvements in PPD (e.g., -1.0 mm for pockets > 5 mm at baseline) were maintained for up to six months after SRP with adjunctive use of 1.7% hydrogen peroxide gel, locally administered using prescription customized trays in the treatment of subjects with moderate to advanced periodontitis.

    ABSTRACT: The primary objective of this study was to compare the effectiveness of NUPRO Sensodyne Prophylaxis Paste with NovaMin, with and without fluoride, to a standard prophylaxis paste without fluoride (control) in reducing dentin hypersensitivity immediately after a single application following dental scaling and root planing. The secondary objective was to compare the duration of sensitivity relief up to 28 days after a single application of the NUPRO pastes with NovaMin compared to the control paste. This was a randomized, single-center, controlled, three-treatment, parallel-group study conducted at Salus Research in Fort Wayne, Indiana. Male and female subjects who met all inclusion/exclusion criteria and had two non-adjacent sensitive teeth based on tactile (Yeaple probe) and air blast assessments, were enrolled in the study. At baseline, tactile and air blast stimuli were administered and subjects were stratified according to their baseline air blast (Schiff) scores into one of three treatment groups: Group A (NovaMin without fluoride), Group B (NovaMin with fluoride) or Group C (NUPRO classic prophylaxis paste without fluoride). Subjects were then assessed post-treatment and at a 28-day follow-up using tactile and air blast methods. A total of 139 patients completed the study. Subjects having received the NovaMin containing prophylaxis pastes (Groups A and B) showed statistically lower (ANOVA, P< 0.05) dentin hypersensitivity compared to the control group immediately after the prophylaxis procedure. Group A tactile improvements were 86% immediate, and 88% after 28 days; air blast improvements were 49% immediate, and 50% after 28 days. Group B tactile improvements were 67% immediate, and 65% after 28 days; air blast improvements were 43% immediate, and 34% after 28 days. Group C experienced little improvement in tactile and air blast scores, 9% and 4% respectively, immediately following treatment, and 10% and 1% respectively after 28 days. At both time points, the reduction in sensitivity was meaningful and significantly better than in the group receiving a standard prophylaxis paste as the comparator (P< 0.05). Both NovaMin pastes were effective and there was no statistical difference between the pastes with and without fluoride. There were no adverse events reported during the course of this study.

    ABSTRACT: Periodontitis is an inflammatory condition of the supporting dental tissues that is normally treated by mechanical removal of the subgingival biofilm. This mechanical treatment, generally known as scaling and root planing (SRP), is not entirely effective, and various adjunctive therapies have been investigated to improve the clinical outcome. This study evaluated the clinical effects of SRP alone or combined with local administration of hydrogen peroxide gel using customized trays in the treatment of subjects with chronic periodontitis. An examiner-blind clinical trial was conducted among 30 subjects with moderate to advanced periodontitis, who were randomized to SRP alone or SRP combined with a prescription custom-tray application (Perio Tray) of 1.7% hydrogen peroxide gel (Perio Gel) for a period of three months. Following impressions for the test group, all subjects brushed twice daily with a regular dentifrice and toothbrush for a four-week acclimation phase to standardize oral conditions (while trays were fabricated) prior to initiating the treatment phase. Clinical assessments, i.e., pocket probing depth (PPD) and bleeding index (BI), were conducted at baseline and after two, five, and 13 weeks of peroxide applications; SRP was performed three weeks after baseline. Clinical variables were compared by ANOVA and paired t-tests after each treatment interval. A total of 13 test and 15 control subjects completed the study. After two weeks of peroxide gel use prior to SRP, mean whole-mouth PPD was unchanged for the control group, but significantly decreased 0.21 mm in the test group. Two weeks following SRP, mean PPD decreased from baseline by 0.17 mm for the control group and 0.65 mm for the test group. Ten weeks following SRP, mean PPD decreases were 0.13 mm for the control group and 0.77 mm for the test group. After two weeks of peroxide use prior to SRP, mean whole-mouth BI decreased 0.03 (from 15% to 12%) for the control and 0.14 (from 23% to 9%) for the test group. Two weeks after SRP, the mean whole-mouth BI score decreased 0.05 from baseline (15% to 10%) for the control and 0.17 (23% to 6%) for the test group. Ten weeks after SRP, there was no change from baseline for the control group, but BI was 0.14 lower (23% to 9%) for the test group. Further analysis showed the same statistical relationship between groups for PPD assessments of deeper pockets. For pockets > or =6 mm at baseline, mean PPD decreased by 0.04 mm for the control compared to 0.48 mm for the test group after two weeks of peroxide gel use and prior to SRP. Two weeks after SRP, mean PPD decreased from baseline by 0.60 mm for the control and 1.40 mm for the test group, and 10 weeks after SRP by 0.58 mm for the control and 1.57 mm for the test group. All reductions cited above for the test group were statistically significantly different from the control group for both PPD and BI. The adjunctive use over three months of 1.7% hydrogen peroxide gel, locally administered using prescription customized trays in the treatment of subjects with moderate to advanced periodontitis, demonstrated statistically significant clinical improvements in pocket depths and bleeding when compared with SRP alone.

    ABSTRACT: To evaluate the 8-week dentin hypersensitivity efficacy of three toothpastes: (1) a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, 0.243% sodium fluoride and specially-designed silica (Test Dentifrice 1); (2) a commercially-available dentifrice containing 0.454% stannous fluoride in a silica base with sodium hexametaphosphate and zinc lactate (Test Dentifrice 2); and (3) a commercially-available non-sensitive dentifrice containing 0.243% sodium fluoride in a silica base (Negative Control Dentifrice). For this 8-week randomized controlled clinical study, qualifying subjects had to have at least two hypersensitive teeth with a tactile hypersensitivity score (Yeaple Probe) between 10 and 50 grams of force, and air blast hypersensitivity score of 2 or 3 (Schiff Cold Air Sensitivity Scale). Subjects brushed twice daily for 1 minute, using the assigned toothpaste and toothbrush. Dentin hypersensitivity assessments, as well as examinations of oral hard and soft tissues, were conducted at the baseline examination and after 4 and 8 weeks of brushing. 118 subjects complied with the protocol, and completed the 8-week study. At baseline, the mean tactile sensitivity scores for toothpastes (1), (2) and (3) were 13.6, 14.1 and 13.1; at 4 weeks 28.75, 20.13, and 20.00; and after 8 weeks 33.1, 24.0 and 20.5, respectively. The mean air blast scores for toothpastes (1), (2), and (3) at baseline were 2.5, 2.5, and 2.4; at 4 weeks 1.25, 1.50 and 1.85; and after 8 weeks 0.99, 1.36 and 1.5, respectively. At all time points after the baseline examination, for both tactile and air blast sensitivity scores, the differences between Test Dentifrice 1 and the Negative Control Dentifrice were statistically significant (P < 0.05). The differences between Test Dentifrice 1 and Test Dentifrice 2 were statistically significant (P < 0.05) at 4 and 8 weeks after baseline examination for tactile sensitivity scores and at 8 weeks after baseline examination for air blast sensitivity scores.

    ABSTRACT: To investigate the efficacy of a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, 0.243% sodium fluoride, and specially-designed silica in controlling established dental plaque and gingivitis. Qualifying adult male and female subjects from the West Palm Beach, Florida area were randomly assigned into one of two treatment groups: (1) a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, 0.243% sodium fluoride, and specially-designed silica (Test Dentifrice); and (2) a dentifrice containing 0.243% sodium fluoride in a silica base (Negative Control Dentifrice). All subjects received an oral soft and hard tissue examination, baseline plaque and gingivitis were assessed, and subjects were dispensed their assigned dentifrice product along with a soft-bristled adult toothbrush for home use. Subjects were instructed to brush their teeth for 1 minute, twice daily (morning and evening), using only the dentifrice provided. Examinations for plaque and gingivitis, and oral soft and hard tissue assessments were repeated after 3 and 6 months of product use. 115 subjects complied with the protocol, and completed the 6-month examination. After 6 months of product use, subjects assigned to the Test Dentifrice group exhibited statistically significant reductions from baseline with respect to Plaque Index, Plaque Severity Index, Gingival Index, and Gingivitis Severity Index scores; and subjects assigned to the Negative Control Dentifrice group exhibited statistically significant reductions from baseline with respect to Gingival Index scores only. Relative to the Negative Control Dentifrice group, the Test Dentifrice group exhibited an 18.8% reduction in Plaque Index; a 50% reduction in Plaque Severity Index; a 19.6% reduction in Gingival Index; and a 60% reduction in Gingivitis Severity Index after 6 months, all of which were statistically significant.

    ABSTRACT: Objectives: To evaluate the plaque removal efficacy of a new toothbrush (Spinbrush Swirl Soft), with a battery-powered spinning head, as compared to a marketed manual toothbrush (Oral-B 40 Indicator Soft). Methods: This was a randomized, examiner-blind, single-use, cross-over study. After refraining from all oral hygiene procedures for 12-16 hours, 88 healthy qualifying subjects who routinely used a manual toothbrush were scored for plaque using the Rustogi modification of the Navy Plaque Index. The subjects brushed with their randomly-assigned brush for a timed 1 min. using regular toothpaste (Crest Regular), and were re-scored for plaque. The procedure was repeated approximately 1 week later with subjects using the alternative toothbrush. The differences between pre- to post-brushing reductions in group mean plaque index scores were analyzed using a baseline-adjusted ANCOVA. Results: Both toothbrushes produced statistically significant within-group whole mouth plaque reductions from baseline (p<0.0001), with SpinBrush and manual brush reductions of 0.380+0.077 (58.7%) and 0.255+0.084 (39.5%), respectively. A between-group comparison showed the SpinBrush to be significantly more effective than the manual brush (p<0.0001) with a 49.0% greater whole-mouth plaque reduction. An analysis of pre- and post-brushing plaque scores from interproximal, gingival, facial, and lingual sites showed similar results: Statistically significant within-group reductions (p<0.0001) ranging from 32.6% to 83.1% for the SpinBrush and from 16.7% to 58.1% for the manual brush, and statistically significant between-group differences (p<0.0001) ranging from 38.5% to 95.2% in favor of SpinBrush. Conclusion: While both toothbrushes produced statistically significant plaque reductions from baseline with a single use, the SpinBrush was significantly more effective than the manual toothbrush at plaque removal.

    ABSTRACT: Objectives: To evaluate the extrinsic stain removal and whitening effectiveness of a tooth-whitening booster used in combination with a regular dentifrice. Methods: This was a randomized, examiner-blind, parallel-group, controlled clinical study. Qualifying subjects with a modified Lobene Stain score of at least 1.5 and a Vita Classical Shade Guide score between A2 and C3 on each of 12 anterior facial surfaces were randomly assigned to one of two groups stratified for stain index, shade, and age: Group 1, marketed dentifrice (Aim Regular) plus whitening booster; Group 2, marketed dentifrice (Aim Regular) without the booster. Subjects brushed at home for 1 min., 2 to 3 times daily for 6 weeks, with evaluations at 1, 3, and 6 weeks. Group 1 subjects overlaid the dentifrice with an equal amount of the whitening booster at each brushing. Reductions from baseline for the two groups were compared using a baseline-adjusted ANCOVA. Results: Sixty-two subjects in Group 1 and 65 subjects in Group 2 completed the study. Stain Index: The groups had similar mean scores at baseline (p>0.05). Group 1 had statistically significant (p<0.001) stain reductions from baseline of 10.8%, 42.4%, and 66.2% at 1, 3, and 6 weeks, respectively; there were no statistically significant reductions in Group 2. Shade: The groups had similar mean scores at baseline (p>0.05). Group 1 had statistically significant shade differences at each evaluation, with a 2.5 shade reduction at 6 weeks (p<0.001). For both stain and shade parameters, Group 1 was significantly more effective than Group 2 (p<0.0001 for stain index and p<0.01 for shade). There were no adverse events or reports of tooth hypersensitivity attributable to the test products. Conclusions: The Arm&Hammer Whitening Booster is effective in reducing extrinsic stain and tooth shade indices. Sponsored by Church&Dwight Co., Inc.

    ABSTRACT: To assess the efficacy ofa dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride for controlling established gingivitis and supragingival plaque relative to that of a dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate, and a dentifrice containing 0.243% sodium fluoride as a negative control. Following a baseline examination for gingivitis and supragingival plaque, qualifying adult male and female subjects from the Piscataway, NJ, USA area were randomized into three dentifrice groups. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice and a soft-bristled toothbrush. Examinations for gingivitis and supragingival plaque were repeated after six weeks of product use. One-hundred and seventy-one (171) subjects complied with the protocol and completed the study. Relative to the group using the dentifrice with 0.243% sodium fluoride alone, the 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride group exhibited statistically significant reductions in gingival index and supragingival plaque index scores of 25.3% and 33.0%, respectively, after six weeks of product use. Similarly, relative to the group using the 0.243% sodium fluoride dentifrice, the 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate dentifrice group exhibited statistically significant reductions in gingival index and plaque index scores of 8.1% and 14.1% after six weeks of product use. Further, relative to the 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate dentifrice group, the 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride dentifrice group exhibited statistically significant reductions in gingival index and plaque index scores of 18.7% and 22%, respectively. The overall results of this double-blind clinical study support the conclusion that a dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride is efficacious for the control of established gingivitis and supragingival plaque as compared to a regular fluoride dentifrice, and that it provides a greater level of efficacy for the control of gingivitis and supragingival plaque than does a dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate.

    ABSTRACT: To compare the efficacy ofa dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, and 0.243% sodium fluoride in controlling established gingivitis and supragingival plaque to that of a commercially available dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate, and a commercially available dentifrice containing 0.243% sodium fluoride. Following a baseline examination for gingivitis and supragingival plaque, qualifying adult male and female subjects from the Mississauga, Ontario, Canada area were randomized into three dentifrice groups. Subjects were instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice and a soft-bristled toothbrush. Examinations for gingivitis and supragingival plaque were repeated after six weeks of product use. One-hundred eighty-two (182) subjects complied with the protocol and completed the study. Relative to the 0.243% sodium fluoride dentifrice group, the 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride dentifrice group exhibited statistically significant reductions in gingival index and supragingival plaque index scores of 26.5% and 29.4%, respectively, after six weeks of product use. Similarly, relative to the 0.243% sodium fluoride dentifrice group, the 0.454% stannous fluoride/sodium hexametaphosphate/zinc lactate dentifrice group exhibited statistically significant reductions in gingival index and plaque index scores of 12.7% and 12.6%, respectively, after six weeks of product use. Further, relative to the 0.454% stannous fluoride/sodium hexametaphosphate/zinc lactate dentifrice group, the 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride dentifrice group exhibited statistically significant reductions in gingival index and plaque index scores of 15.8% and 19.2%, respectively. The overall results of this double-blind clinical study support the conclusion that a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, and 0.243% sodium fluoride is efficacious for the control of established gingivitis and supragingival plaque, and that it provides a greater level of efficacy for the control of gingivitis and supragingival plaque than does a dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate.

    ABSTRACT: This double-blind clinical study, conducted at the University of Puerto Rico, San Juan, Puerto Rico, was designed to compare the efficacy of two commercially available dentifrices for the control of supragingival plaque and gingivitis. Qualifying adult male and female subjects from the San Juan, Puerto Rico area were randomly assigned to one of two treatment groups: 1) a commercially available dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, and 0.243% sodium fluoride (Colgate Total); and 2) a commercially available dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate (Crest Pro-Health). All subjects received an oral soft and hard tissue examination, and were dispensed their assigned dentifrice product, along with a soft-bristled adult toothbrush for home use. Subjects were instructed to brush their teeth for one minute, twice daily (morning and evening), using only the dentifrice provided. Examinations for supragingival plaque and gingivitis, and oral soft and hard tissue assessments were repeated after six weeks, three months, and six months of product use. One-hundred and nine (109) subjects complied with the protocol and completed the six-month examinations. At the six-month examination, both treatment groups exhibited statistically significant reductions from baseline with respect to supragingival plaque and gingivitis scores. Relative to the Crest Pro-Health Toothpaste group, the Colgate Total Toothpaste group exhibited statistically significant reductions in supragingival plaque index scores of 18.5%, 20.7%, and 25.8% after six weeks, three months, and six months of product use, respectively. For gingival index scores, statistically significant reductions of 20.5%, 18.9%, and 17.1% were exhibited after six weeks, three months, and six months of product use, respectively. The results of this double-blind clinical study support the conclusion that a dentifrice containing 0.3% triclosan, 2.0% PVM/MA copolymer, and 0.243% sodium fluoride provides a significant reduction in established supragingival plaque and gingivitis, as compared to a dentifrice containing 0.454% stannous fluoride, sodium hexametaphosphate, and zinc lactate when used over a period of six months.

    ABSTRACT: OBJECTIVE: The objective of this eight-week, double-blind, parallel-group clinical study, conducted in Canada, was to investigate the efficacy of a new anti-sensitivity triclosan/copolymer/silicon dioxide/NaF dentifrice (Colgate Total containing a specially-designed silica to occlude tubules, Test Dentifrice) for the reduction of dentinal hypersensitivity. METHODS: Following a baseline hypersensitivity examination, eighty-two qualifying adults were randomized into two treatment groups balanced for hypersensitivity scores to tactile and air-blast stimuli: (1) Test Dentifrice; (2) a commercially-available non-desensitizing dentifrice, Crest Cavity Protection Toothpaste, containing 0.243% NaF (Control Dentifrice). Subjects were instructed to brush their teeth at home for one minute, twice daily (mornings and evenings), using only their assigned dentifrice product and provided soft-bristled adult toothbrush. Hypersensitivity examinations were repeated after four and eight weeks of product use. RESULTS: Eighty-two subjects completed all study visits. At both the four-week and the eight-week examinations, the Test Dentifrice group exhibited statistically significantly more favorable tactile hypersensitivity scores than did the Control Dentifrice group, with improvements of 31.6% and 52.1%, respectively. Additionally, at both the four-week and eight-week examinations, the Test Dentifrice group exhibited statistically significantly more favorable air blast hypersensitivity scores than did the Control Dentifrice group, with improvements of 17.8% and 23.6%, respectively. CONCLUSION: The results of this clinical study support the conclusions that a new anti-sensitivity triclosan/copolymer/silicon dioxide/NaF dentifrice (Colgate Total containing a specially-designed silica to occlude tubules) provides (1) a significant reduction of hypersensitivity after four and eight weeks of product use, and provides (2) significant improvements in dentinal hypersensitivity as compared to the commercially-available non-desensitizing fluoride dentifrice after four and eight weeks of product use.

    ABSTRACT: Objective: Compare the effects of experimental sodium fluoride/silica toothpaste [ED: 1100 ppm fluoride (F)]and commercially-available dentifrice Aquafresh Cavity Protection (CD: 1100 ppm F; sodium monofluorophosphate) on in situ enamel remineralization, F uptake, plaque fluid and salivary F during the retention phase of F delivery. Methods: The pilot study (n=14) involved a three treatment period, examiner-blind, crossover study design. Treatments consisted of ED, CD, and placebo dentifrice (PD: 0 ppm F). At the beginning of each treatment period saliva sampling was performed at baseline, immediately after treatment (brushing for one minute with assigned dentifrice), and at 7.5-, 15-, 30-, 60-, and 120-min post-treatment. Plaque fluid sampling was performed at baseline, 30-, 60-, and 120-min post-treatment. The subject's partial denture, which held two gauze-covered human enamel specimens, was inserted after saliva and plaque collection. For the remainder of the 14-day test period, subjects brushed twice per day with their assigned dentifrice with the partial denture removed from their mouth before reinserting. At the end of each treatment period, the two enamel specimens were recovered and evaluated for percent surface microhardness recovery and F uptake. Results: ED exhibited a statistically significantly greater (p = 0.006) meanSD %SMH recovery (33.717.2) compared to PD (19.511.5). No difference was indicated between CD (25.212.3) and PD. Both ED and CD had statistically significantly higher mean fluoride uptake (p = 0.0002, 0.005, respectively), higher salivary F levels at all post-treatment timepoints compared to PD, and at the 120-min post-treatment timepoint higher levels of plaque fluid F compared to PD. There were no significant differences between EC and CD for any of the parameters tested. Conclusions: Evaluation of the retention phase of F delivery using an in situ caries model in combination with salivary and plaque fluid F clearance appear to be useful surrogate measures of F efficacy.

    ABSTRACT: This retrospective radiographic evaluation provided a comparative assessment of long-term alterations of alveolar bone levels at sites with angular and horizontal bony defects that underwent open-flap debridement and did not undergo resective or regenerative periodontal therapy. The investigation included 50 patients (27 met inclusion criteria) who had periodontal surgery and periodontal maintenance every 3 to 6 months and who presented with sites demonstrating radiographic angular defects and sites on adjacent or contralateral teeth that demonstrated horizontal bone loss. Subsequent to surgical therapy, alterations in bone levels at the alveolar crest of horizontal defects and at the base of angular defects were evaluated by comparing radiographs from the initial examination to those obtained after a period of periodontal maintenance (6 to 16 years; mean: 8.83 years). After periodontal therapy, sites with angular and horizontal alveolar bone loss had additional bone loss of 5.56% and 3.88%, respectively. Based on a defining criterion of 10%, the angular and horizontal sites were clinically equivalent with respect to the magnitude of osseous resorption that occurred after periodontal surgery and maintenance.

    ABSTRACT: The objective of this independent, double-blind, parallel, six-week clinical study was to assess the efficacy of a commercially available mouthrinse containing 0.05% cetylpyridinium chloride (CPC) for controlling established dental plaque and gingivitis relative to that of a control mouthrinse without CPC. Adult male and female subjects from the Maceió, Brazil area reported to the clinical facility, after having refrained from any oral hygiene procedures for 12 hours, and from eating, drinking, and smoking for four hours, for an assessment of the oral soft and hard tissues, and for a baseline gingivitis and dental plaque evaluation. Qualifying subjects were randomly assigned to one of the two treatment groups, and were provided with their assigned mouthrinse, and an adult soft-bristled toothbrush and toothpaste for home use. Over the six-week period of home use, during which there were no restrictions regarding diet or smoking habits, subjects were instructed to brush their teeth for one minute twice daily with the supplied toothbrush and a commercially available fluoride toothpaste, to rinse their mouths with water after brushing, and then to rinse with their assigned mouthrinse for one minute before expectorating. The use of any other oral hygiene products or procedures, such as floss or interdental stimulators, was not permitted during the study. After six weeks of product use, subjects returned to the clinical facility, having followed the same restrictions with respect to oral-hygiene procedures, eating and drinking, as with the baseline visit, and the oral soft and hard tissue assessments and gingivitis and dental plaque evaluations were repeated. One-hundred and ten subjects complied with the protocol and completed the study. With regard to supragingival plaque, after six weeks of product use, the subjects using the 0.05% CPC mouthrinse exhibited statistically significant reductions from baseline in whole-mouth Plaque Index scores (32.1%), in Plaque Index scores measured at interproximal sites (31.3%), and in Plaque Severity Index scores (84.8%). Subjects using the control mouthrinse exhibited statistically significant reductions from baseline in whole-mouth Plaque Index scores (7.0%), in Plaque Index scores measured at interproximal sites (6.4%), and in Plaque Severity Index scores (24.5%). When compared to the control mouthrinse group, the 0.05% CPC mouthrinse group presented statistically significant greater reductions in whole-mouth Plaque Index scores (27.9%), in Plaque Index scores measured at interproximal sites (27.9%), and in Plaque Severity Index scores (81.1%) after six weeks of product use. With regard to gingivitis, after six weeks of product use, subjects using the 0.05% CPC mouthrinse exhibited statistically significant reductions from baseline in whole-mouth Gingival Index scores (25.0%), in Gingival Index scores measured at interproximal sites (25.3%), and in Gingivitis Severity Index scores (42.4%). Subjects using the control mouthrinse exhibited statistically significant reductions from baseline in whole-mouth Gingival Index scores (6.5%), in Gingival Index scores measured at interproximal sites (5.5%), and in Gingivitis Severity Index scores (11.6%). When compared to the control mouthrinse group, the 0.05% CPC mouthrinse group presented statistically significant greater reductions in whole-mouth Gingival Index scores (19.8%), in Gingival Index scores measured at interproximal sites (20.7%), and in Gingivitis Severity Index scores (35.5%) after six weeks of product use. The results of this double-blind, parallel, six-week clinical study support the conclusion that a mouthrinse containing 0.05% CPC is efficacious for controlling established dental plaque and gingivitis. As measurements were conducted 12 hours after product use, the results also demonstrate that the 0.5% CPC mouthrinse provides 12-hour protection against plaque and gingivitis.

    ABSTRACT: The objective of this independent, double-blind, seven-day clinical study was to assess the efficacy of a commercially available mouthrinse containing 0.05% cetylpyridinium chloride (CPC) in preventing dental plaque build-up relative to that of a control mouthrinse without 0.05% CPC. Adult male and female subjects from the São Paulo, Brazil area reported to the clinical facility, having refrained from any oral hygiene procedures for 12 hours, and from eating, drinking, and smoking for four hours, for an assessment of the oral soft and hard tissues and a baseline dental plaque evaluation. Subjects qualifying for participation received a complete dental prophylaxis. Qualifying subjects were randomly assigned into one of the two treatment groups and were provided with their assigned mouthrinse, an adult soft-bristled toothbrush, and a commercially available fluoride toothpaste for home use. Over the seven-day period of home use, during which there were no restrictions regarding diet or smoking habits, subjects were instructed to brush their teeth for one minute twice daily (morning and evening) with the toothbrush and toothpaste supplied, to rinse their mouths with water after brushing, and then to rinse with 15 ml of their assigned mouthrinse for one minute before expectorating. The use of other oral hygiene products or procedures, such as floss or interdental stimulators, was not permitted during the study. After seven days of product use, subjects returned to the clinical facility having followed the same restrictions with respect to oral hygiene procedures, eating and drinking, as prior to the baseline examination, and the oral soft and hard tissue assessments and dental plaque evaluations were repeated. Forty-three subjects complied with the protocol and completed the study. Results demonstrated that after seven days of product use, mean plaque levels were statistically significantly lower (p < 0.05) than the pre-prophylaxis levels for both treatment groups. The mean plaque level for the CPC mouthrinse group was 46.1% of the pre-prophylaxis plaque level, whereas the mean plaque level for the control mouthrinse group was 75.5% of the pre-prophylaxis plaque level. The results demonstrate a statistically significant reduction in plaque build-up for the CPC mouthrinse group (29.3%) as compared to the control group. The overall results from this double-blind clinical study support the conclusion that, after seven days of product use, a mouthrinse containing 0.05% CPC provides significantly greater efficacy in preventing dental plaque build-up than a control mouthrinse without 0.05% CPC. As measurements were made 12 hours after final product use, the results also demonstrate that the CPC rinse provides 12-hour protection against dental plaque build-up.

    ABSTRACT: To evaluate the effect of toothpaste treatments on levels of oral volatile sulphur compounds (VSCs) measured by gas chromatography in two clinical studies. These were blinded, randomised, controlled, crossover studies with 16 (study A) or 20 (study B) healthy volunteers between the ages of 19-54. Study A: breath samples were collected at baseline, immediately and lhr after brushing. Four dentifrices (Zinc A, Zinc B, commercially available triclosan dentifrice and zinc free control) were evaluated. Study B: breath samples were collected at baseline, immediately, 1, 2, 3 and 7 hours after treatment. Subjects consumed a light breakfast then provided an additional breath sample between baseline assessment and treatment. Two dentifrices (gel-to-foam and a commercially available triclosan dentrifrice) were evaluated. Breath samples were collected in syringes and analysed for VSCs (hydrogen sulphide, methyl mercaptan and Total VSCs) utilising gas chromatography (GC) with flame photometric detection. Study A: immediately after treatment, a statistically significant reduction in VSCs from baseline was observed for Zinc A product only. A statistically significant reduction in VSCs from baseline was observed after 1 hour for all products. Both zinc products exhibited a significantly greater reduction from baseline VSCs than Colgate Total and Control at all time points. Study B: a statistically significant reduction in VSCs from baseline was observed at all time points for both products. The gel-to-foam product exhibited significantly greater reduction from baseline Total VSC concentration than Colgate Total at all time points from 1 hour post-treatment. Control of oral malodour by toothpaste treatment, evaluated as VSC levels using GC, has been demonstrated. Zinc is effective at reducing VSCs and the efficacy of zinc is formulation dependent. A gel-to-foam dentifrice was more effective at reducing VSCs than Colgate Total up to 7 hours.

    ABSTRACT: The objective of this independent, double-blind, overnight clinical study was to assess the efficacy of a dentifrice containing 0.3% triclosan/2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.243% sodium fluoride in a 17% dual silica base (Colgate Total Advanced Toothpaste) for the overnight control of oral malodor and plaque microflora, relative to that of a commercially available dentifrice containing 0.243% sodium fluoride in a silica base (Crest Cavity Protection Toothpaste). After a five-day period using a supplied commercially available fluoride toothpaste, adult male and female subjects from the Chengdu, China area reported to the clinical facility in the evening, after having refrained from the use of all oral hygiene procedures, as well as eating and drinking, for at least six hours. Following an assessment of the oral soft and hard tissues, subjects were evaluated for baseline oral malodor by a panel of four trained judges using a nine-point hedonic scale. Plaque samples (baseline) from the teeth on the left side of subjects' mouths were also collected. Subjects who presented a mean baseline oral malodor score between 6.0 and 8.4 were stratified according to their oral malodor score and randomly assigned within strata to one of the two treatment groups. Subjects were provided with their assigned dentifrice and instructed to brush their teeth on the left side of their mouth only, for one minute under supervision. Subjects returned to the testing facility the following morning for an overnight evaluation, having refrained from the use of all oral hygiene procedures, and from eating and drinking. An oral malodor assessment was performed, plaque samples were collected from the teeth on the right side of the mouth, and a final oral soft and hard tissue evaluation was performed. Eighty-one (81) subjects completed the study. At the overnight evaluation, subjects in the triclosan/copolymer/fluoride dentifrice group and the fluoride dentifrice group presented mean oral malodor scores of 4.91 and 6.86, respectively. Relative to the fluoride dentifrice group, at the overnight evaluation the triclosan/copolymer/fluoride dentifrice group presented a statistically significant 28.4% reduction in oral malodor scores. Additionally, at the overnight evaluation, subjects in the triclosan/ copolymer/fluoride dentifrice group and the fluoride dentifrice group presented geometric mean microbial colony forming unit (CFU) scores of 3.15 and 6.07, respectively. Relative to the fluoride dentifrice group, at the overnight evaluation the triclosan/copolymer/ fluoride dentifrice group presented a statistically significant 49.5% reduction in microbial CFU scores. The overall results of this double-blind clinical study support the conclusion that a single evening's use of a dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride in a 17% dual silica base provides statistically significantly lower levels of overnight (12-hour) oral malodor and plaque microflora when compared to a commercially available dentifrice containing 0.243% sodium fluoride in a silica base.

    ABSTRACT: To assess the efficacy of a dentifrice containing 0.3% triclosan/2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.243% sodium fluoride in a 17% dual silica base (Colgate Total Advanced Toothpaste-Test Dentifrice) for controlling established supragingival plaque and gingivitis, relative to that of a commercially available dentifrice containing 0.243% sodium fluoride in a silica base (Crest Cavity Protection Toothpaste-Control Dentifrice). Following a baseline examination for supragingival plaque and gingivitis, qualifying adult male and female subjects from the Barcelona, Spain area were randomized into two treatment groups. Subjects were given a complete oral prophylaxis and instructed to brush their teeth twice daily (morning and evening) for one minute with their assigned dentifrice and a soft-bristled toothbrush. Examinations for supragingival plaque and gingivitis were repeated after three months and six months of product use. Ninety-four (94) subjects complied with the protocol and completed the study. Relative to the Control Dentifrice group, the Test Dentifrice group presented statistically significantly lower whole-mouth plaque index and gingival index scores (18.6% and 15.8%, respectively) after three months of product use. Similarly, relative to the Control Dentifrice group, the Test Dentifrice group exhibited statistically significant reductions in plaque index and gingival index scores measured on proximal sites (17.0% and 16.3%,respectively), and statistically significant reductions in plaque severity index and gingivitis severity index scores (22.2% and 46.9%, respectively) after three months of product use. Relative to the Control Dentifrice group, the Test Dentifrice group presented statistically significantly lower whole-mouth plaque index and gingival index scores (23.4% and 21.3%, respectively) after six months of product use. Similarly, relative to the Control Dentifrice group, the Test Dentifrice group exhibited statistically significant reductions in plaque index and gingival index scores measured on proximal sites (21.1% and 23.0%, respectively), and statistically significant reductions in plaque severity index and gingival severity index scores (27.1% and 64.5%, respectively) after six months of product use. The overall results of this double-blind clinical study, conducted in accordance with the quantitative criteria established by the American Dental Association, support the conclusion that a dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride in a 17% dual silica base is efficacious for the control of established supragingival plaque and gingivitis.

    ABSTRACT: The objective of these two six-week, double-blind clinical studies was to compare the extrinsic stain prevention (Study #1) and stain removal (Study #2) efficacy of a new dentifrice (Colgate Total Advanced Toothpaste) containing 0.3% triclosan/ 2.0% polyvinylmethyl ether/maleic acid (PVM/MA) copolymer/0.243% sodium fluoride in a 17% dual silica base, to a commercially available fluoride dentifrice without tooth whitening ingredients (Crest Cavity Protection Toothpaste) containing 0.243% sodium fluoride in a silica base. Following baseline examinations for extrinsic tooth stain and an oral tissue examination, qualifying adult male and female subjects from the northern and central New Jersey, USA areas were randomized for each study into two treatment groups which were balanced for gender and level of extrinsic tooth stain. Subjects received a full oral prophylaxis at the start of Study #1 only. All subjects were provided with their assigned product and a soft-bristled adult toothbrush for home use. Subjects were instructed to brush their teeth for one minute twice daily (morning and evening) using only the dentifrice and toothbrush provided, and to refrain from using any other oral hygiene products for the entire six weeks of the study. There were no restrictions regarding diet or smoking habits during the course of the study. Examinations for extrinsic tooth stain and oral tissue assessments were repeated after three weeks and six weeks of product use. One-hundred fourteen (114) subjects participating in Study #1 and 119 subjects participating in Study #2 complied with the protocol and completed the entire study. In both studies, at the three-week and the six-week examinations, subjects who used the new dentifrice exhibited statistically significantly lower levels of extrinsic tooth stain area and extrinsic tooth stain intensity than did those subjects who used the commercially available fluoride control dentifrice. A new dentifrice containing 0.3% triclosan/2.0% PVM/MA copolymer/0.243% sodium fluoride in a 17% dual silica base is more efficacious in the prevention and removal of extrinsic tooth stain than a commercially marketed fluoride dentifrice.
