ABSTRACT: Caries clinical trials of sugar-free chewing gum have shown that the gum is noncariogenic and in fact has anticariogenic effect through the stimulation of saliva. Sugar-free gums, therefore, may be an excellent delivery vehicle for safe and effective additive, capable of promoting enamel remineralization. Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) nanocomplexes incorporated into sugar-free chewing gum have shown to remineralize enamel subsurface lesions in situ. So this study was conducted to evaluate the effect of CPP-ACP containing sugar-free chewing gum on salivary concentration of calcium and phosphorous.
Unstimulated saliva from each 24 selected subjects was collected. Then each subject was given two pellets of chewing gum containing CPP-ACP and asked to chew for a period of 20 min, after which saliva samples were collected from each individual. Once all the samples were collected they were assessed for calcium and phosphorous concentration using affiliated reagent kits and photometer.
Data obtained were analyzed using student's paired t test.
Significant difference was found in the calcium and phosphorus concentration of saliva before and after chewing CPP-ACP containing chewing gum.
Chewing of CPP-ACP containing chewing gum showed a significant increase in the salivary concentration of calcium for a prolonged period of time hence it may help in the remineralization of tooth surfaces.

ABSTRACT: Tooth transplantation has attracted great interests since ancient times. A successful case of tooth allotransplantation is presented. A mandibular first premolar from the donor was implanted into the socket of maxillary central incisor Follow up after 12 months indicated good periapical healing with no resorption. Clinically, the transplantation site was free of symptoms and there was no evidence of periodontal disease or tooth mobility. This article suggests tooth transplantation as an alternative to other restorative options.

ABSTRACT: To evaluate and compare shear bond strengths of composite resins to primary enamel and dentine when the adhesives are pre-cured (light cured before the application of the resin) or co-cured (adhesive and the resin light cured together).
Buccal surfaces of 80 caries-free primary molars were wet ground to create bonding surfaces on enamel and dentine and specimens mounted on acrylic blocks. Two bonding agents (Prime and Bond NT® and Xeno III®) were applied to either enamel or dentine as per manufacturer's instructions. In 40 specimens, the bonding agent was light cured immediately after the application (pre-cured). The other 40 specimens were not light cured until the composite resin application (co-cured). Resin composite cylinders were made incrementally using acrylic moulds over the adhesives and light cured. Specimens were stored in deionised water for 24 hours at room temperature. Shear bond strength was measured using an Instron universal testing machine (in MPa) and was analysed with Student's unpaired t test.
Light curing the adhesive separately produced significantly higher bond strengths to primary dentine than co-curing (p<0.001). At the same time light curing the adhesive separately did not produce significantly different bond strengths to primary enamel (p>0.05).
Curing sequence had no significant effect on shear bond strength of adhesives on the primary enamel. Pre-curing adhesives before curing composite resins produced greater shear bond strength to primary dentine.

ABSTRACT: Trauma to the deciduous teeth may have severe consequences. Pulp necrosis is the commonly observed sequel in traumatized primary teeth and is one of the possible etiologic factors for the development of dentigerous cyst. Dentigerous cyst is more commonly seen in mandibular third molar and maxillary canine region and is rarely associated with other teeth. This article addresses a case of dentigerous cyst associated with the germ of upper permanent central incisor, an uncommon site of occurrence, which was impacted, dislodged from its natural site of eruption after trauma to the predecessor incisor.

ABSTRACT: Conservative procedures using dentin bonding agents are one of the important aspects of paediatric dental practice. The objective of this in vitro study was to comparatively evaluate the microleakage of two self etching adhesives in primary and permanent teeth.
Sixty-four human anterior teeth (thirty-two primary and thirty-two permanent) were divided into four groups: primary teeth bonded using a 6th generation (Contax) bonding agent; permanent teeth bonded using a 6(th) generation (Contax) bonding agent; primary teeth bonded using a 7(th) generation (Clearfil S3) bonding agent; permanent teeth bonded using a 7(th) generation (Clearfil S3) bonding agent. A Class V cavity was prepared on all samples and were restored with composite resin as per manufacturers' instruction. After thermocycling, the teeth were stained with methylene blue, sectioned, and measured for microleakage.
It was found a statistically significant difference in microleakage between incisal and gingival margins in each of the study group.
Clearfil S3 (7(th) generation) bonding agent could be of greater advantage in paediatric dentistry than Contax (6(th) generation) because of its fewer steps and lesser microleakage in both primary and permanent teeth.

ABSTRACT: Many parents are often unaware of the hidden, added sugars in many foods and drinks including pediatric liquid medicines; thus, hidden sugar in the form of pediatric medications has not been focused upon as cariogenic agents.
(i) assess concentration of sucrose in six pediatric drugs, (ii) determine endogenous pH of these drugs, and (iii) estimate drop in the plaque pH in the oral cavity in first 30 minutes after consumption of the drugs.
Ten adult volunteers with mean age of 22 years were double blinded for the study. Concentration of sucrose was assessed by volumetric method at Department of Chemical Branch of Engineering. Endogenous pH and drop in the plaque pH after consumption of the drugs were assessed using digital pH meter.
SPSS software was used to assess the pH level at different time intervals and expressed as mean +/- SD. Changes in pH were assessed by one-way ANOVA followed by Wilcoxons signed rank test. P-value was set at 0.05.
There were varying amounts of fermentable sucrose detected in the drugs; all the drugs were acidic. There is a significant drop of plaque pH after consumption of the drug.
These sweeteners along with their low endogenic pH form a high cariogenic formulation. Thus, nonsucrose (noncariogenic) or sugar-free medications are needed to be prescribed along with proper oral hygiene care to the children under medication.

ABSTRACT: The present study was undertaken to compare and evaluate shear bond strength of two self-etching adhesives (sixth and seventh generation) on dentin of primary and permanent teeth.
Flat dentin surface of 64 human anterior teeth (32 primary and 32 permanent) divided into four groups of 16 each. Groups A and C were treated with Contax (sixth generation), while groups B and D were treated with Clearfil S3 (seventh generation). A teflon mold was used to build the composite (Filtek Z-350) cylinders on the dentinal surface of all the specimens. Shear bond strength was tested for all the specimens with an Instron Universal Testing Machine. Data were statistically analyzed using one-way ANOVA for multiple group comparison, followed by student's unpaired 't' test for group-wise comparison.
There was no statistically significant difference in shear bond strength among the study groups except that primary teeth bonded with Contax exhibited significantly lesser shear bond strength than permanent teeth bonded with Clearfil S3.
This study revealed that Clearfil S3 could be of greater advantage in pediatric dentistry than Contax because of its fewer steps and better shear bond strength in dentin of both primary and permanent teeth.

ABSTRACT: Lactoperoxidase system contains Lactoperoxidase, Hydrogen peroxide and Thiocyanate ions, which have inhibitory action against cariogenic oral microflora. The present study was undertaken to assess the effect of lactoperoxidase system containing toothpaste on cariogenic microflora in children with early childhood caries.
Study group included 30 children with Early Childhood Caries. 15 were considered as test group who used the test product Biotene toothpaste and other 15 as control group who used Colgate Active as control product. Salivary samples were analyzed for mutans streptococci (MS) and Lactobacilli, and for the levels of Thiocyanate ions.
Showed significant increase in the levels of Thiocyanate ion in saliva during experimental period. Compared to the control group test group showed significant increase in the levels of thiocyanate ions during experimental and washout period, whereas the number of colonies of MS and Lactobacilli were significantly reduced in test group during experimental period.
The levels of thiocyanate ions can be increased in vivo by supplementing the saliva with natural enzymes like lactoperoxidase. This increased concentration of thiocyanate will reduce the number of cariogenic microflora in children with Early Childhood Caries.

ABSTRACT: The purpose of present study was to investigate the antibacterial activity of three commercially available fluoride- and zinc-releasing glass ionomer cements on strains of mutans streptococci. Three glass ionomers (Fuji II Conventional, Fuji II Light Cure, and Fuji IX) were used. The antibacterial effect of glass ionomer cements were estimated by anaerobically growing mutans streptococci on a selective medium by inoculating human saliva and measuring the inhibition zones around the glass ionomer discs on the medium. Fluoride and zinc release were measured and compared with the antibacterial activity. The results, when statistically analyzed, showed a direct correlation between fluoride release and antibacterial activity, but there was no correlation between zinc release and antibacterial activity.

ABSTRACT: Garre's sclerosing osteomyelitis is a specific type of chronic osteomyelitis that mainly affects children and young adults. This disease entity is well-described in dental literature and is commonly associated with an odontogenic infection resulting from dental caries. This paper describes a case of Garre's osteomyelitis in a 10-year-old boy, in whom the condition arose following pulpoperiapical infection in relation to permanent mandibular right first molar. Clinically the patient presented with bony hard, non-tender swelling and the occlusal radiograph revealed pathognomic feature of "onion skin" appearance. The elimination of periapical infection was achieved by endodontic therapy and the complete bone remodeling was seen radiographically after three months follow-up.

ABSTRACT: The objectives of this study were to evaluate and compare the amount and pattern of fluoride release from teeth after topical application of 2% NaF, 8% SnF2 and 1.23% APF at different time intervals. The growth inhibitory effects of this released fluoride ion was assessed on mutans streptococci (MS) and correlated with the fluoride release. Forty premolars divided into four groups were subjected to different topical fluoride treatments. All the teeth were immersed individually in deionized water and were transferred to containers at 1 hour, 1 day and 1 week time intervals. 240 samples in total were used for fluoride estimation by ion selective electrode method and the samples from the other subgroup were used for evaluation of antimicrobial activity on mutans streptococci (MS) by bacterial inhibition assay method. The results showed that the highest fluoride release (7.83 +/- 0.55 ppm) was seen in SnF2 treated specimens, as compared to that of NaF (3.71 +/- 0.60ppm) and APF (3.30 +/- 0.51ppm), the difference being statistically significant (P<0.01). This was observed immediately after 1 hour, followed by a drastic reduction thereafter. No zones of inhibition were observed at the released fluoride concentrations at different time intervals in the different groups. IN CONCLUSION: 8% SnF2 is expected to have greater anticaries property from the high fluoride releasing property for prolonged period of time.

ABSTRACT: Talon cusp is a supernumerary crown structure, a developmental disturbance in the shape of teeth that causes various diagnostic, functional and esthetic problems. Some synonyms for talon cusp are dens evaginatus of anterior teeth, interstitial cusp, tuberculated tooth, odontoma of the axial core type, evaginated odontoma, enamel pearl, supernumerary cusp etc. The lingual location on incisors, which frequently affects occlusion, is pathognomonic of the talon cusp. This report describes a rare odontogenic, isolated anomaly rather than an integral part of any disorder, a case of talon shaped cusp projecting from the labial surface of a maxillary permanent central incisor.

ABSTRACT: The present study was performed to compare the amount of in vitro fluoride uptake by enamel and dentin from fluoridated bonding agent with non-fluoridated composite (Group I), non-fluoridated bonding agent with fluoridated composite (Group II) and fluoridated bonding agent with fluoridated composite resin (Group III). Sixty extracted premolars were selected and divided into three groups of 20 teeth each. Restorative materials were applied according to manufacturer's instructions into standard windows created in the teeth, cured and placed in de-ionised water for three months. The fluoride content of successive acid etch biopsy was determined by specific ion-electrode analysis. Although significant amount of fluoride uptake occurred in all the test groups, fluoride uptake was found to be highly significant in dentin when compared to enamel in Group, I, II and III (P<0.001). The fluoride uptake was greater by both enamel and dentin in Group III ie fluoridated bonding agent with fluoridated composite resin.

ABSTRACT: This study was undertaken to assess the effect of a single application of three professionally applied topical fluoride agents (Sodium fluoride 2%, Stannous fluoride 8% and APF 1.23%) on the surfaces of six modern esthetic restorative materials used in pediatric dentistry viz., two conventional glass ionomers (Fuji II and Shofu-restorative), two resin modified glass ionomers (Vitremer, with and without glaze, and Photac-fil Quick) and two Polyacid modified composite resins (Luxat and Hytac Aplitip). Mean surface roughness and surface micro hardness (SMH) measurements were the parameters employed for comparison. Results showed that APF gel applications significantly increased the surface roughness measurements and decreased SMH of all tested materials, which was pronounced in conventional glass ionomers when compared with resin modified glass ionomers and polyacid modified composite resins. NaF and SnF2 produced a statistically significant increase in the surface roughness of conventional glass ionomers without any significant change in surface roughness and SMH on rest of the materials tested, except for NaF on SMH values of Fuji II, which was statistically significant.
