    ABSTRACT: Purpose The aim of this study was to investigate the push-out bond strength (PBS) of resin-relined and non-relined glass fiber posts (GFP) luted to flared root canals. Material and methods Root canals of 80 bovine incisors were enlarged to obtain 40 mildly flared and 40 over-flared post spaces. Half of the specimens from each group had the GFP resin-relined, whilst the remainders were not relined. A further 20 root canals were minimally flared and restored with a non-relined GFP (control group). Posts were luted into the root canal space using dual-cure resin cement. Three slices were sectioned from each specimen: one from the coronal third and the others from the middle and apical thirds. PBS test was performed in a universal testing machine at a speed of 0.5 mm/min. Results Two-way ANOVA for repeated measures and Tukey's test showed that PBS was affected by the root canal flare and relining procedure (p<0.001). Relining significantly increased the PBS of GFP luted in roots with mildly flared canals when compared to those with excessive widening, regardless of the relining procedure. Relining GFP for over-flared canals had a PBS equivalent to that observed in the control group (minimally flared canal/non-relined GFP). PBS values were higher in the coronal third. No difference was found between the PBS values in the middle and apical thirds. Conclusions Depending on the extent of the root canal flare, relined fiber posts may outperform or at least perform as well as posts luted in minimally-flared canals.

    ABSTRACT: This study examined the effect of cariogenic and erosive challenges (CCs and ECs, respectively) on the degradation of copper-nickel-titanium (CuNiTi) orthodontic wires. Sixty wire segments were divided into four treatment groups and exposed to CCs, ECs, artificial saliva, or dry storage (no-treatment control). CC and EC were simulated using a demineralizing solution (pH 4.3) and a citric acid solution (pH 2.3), respectively. Following treatment, the average surface roughness (Ra) of the wires was assessed, and friction between the wires and a passive self-ligating bracket was measured. CuNiTi wires subjected to ECs exhibited significantly higher Ra values than did those that were stored in artificial saliva. In contrast, surface roughness was not affected by CCs. Finally, friction between the treated wires and brackets was not affected by ECs or CCs. Our results indicate that CuNiTi orthodontic wires may suffer degradation within the oral cavity, as ECs increased the surface roughness of these wires. However, rougher surfaces did not increase friction between the wire and the passive self-ligating bracket.

    ABSTRACT: The aim was to assess the nanohardness (H) and the reduced modulus of elasticity (Er) of 2.5% titanium tetrafluoride (TiF4) modified dentin, before and after an erosive challenge with 0.3% citric acid (CA). Exposed dentin surfaces were divided into two groups (n = 5): (1) Control—no dentin pretreatment with TiF4 prior to etching with CA, and (2) Experimental—dentin pretreatment with TiF4 + CA. The H and the Er of intertubular dentin were measured using a triboindenter at different time points: baseline for both groups, after using 2.5% TiF4 for the experimental group, and after using CA for both the experimental and the control groups. Scanning electron microscope and energy dispersive X-ray spectroscopy (EDS) analysis of the dentin surfaces were undertaken at the same time points for both groups. Two-way ANOVA for randomized block design was applied. There was significant interaction between the application of the TiF4 solution and different time points (p = 0.001 for H and p < 0.001 for Er), identified by Tukey's test. Erosive challenge provided a significant decrease in H and Er mean values. The TiF4 solution caused a significant increase in H and Er values, but no significant differences were found between post-TiF4 and post-CA application. TiF4 application produced a precipitate surface layer on intertubular and intratubular dentin. EDS analysis indicated the presence of titanium. The H and Er of the dentin surface were greatly increased after application of 2.5% TiF4. TiF4 may modify the micromorphology of the dentin surface and produces an erosive resistance surface. © 2014 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2014.

    ABSTRACT: The present study aimed to evaluate in situ the effect of CO2 laser irradiation to control the progression of enamel erosive lesions. Fifty-six slabs of bovine incisors enamel (5 × 3 × 2.5 mm(3) ) were divided in four distinct areas: (1) sound (reference area), (2) initial erosion, (3) treatment (irradiated or nonirradiated with CO2 laser), (4) final erosion (after in situ phase). The initial erosive challenge was performed with 1% citric acid (pH = 2.3), for 5 min, 2×/day, for 2 days. The slabs were divided in two groups according to surface treatment: irradiated with CO2 laser (λ = 10.6 µm; 0.5 W) and nonirradiate. After a 2-day lead-in period, 14 volunteers wore an intraoral palatal appliance containing two slabs (irradiated and nonirradiated), in two intraoral phases of 5 days each. Following a cross-over design during the first intraoral phase, half of the volunteers immersed the appliance in 100 mL of citric acid for 5 min, 3×/day, while other half of the volunteers used deionized water (control). The volunteers were crossed over in the second phase. Enamel wear was determined by an optical 3D profilometer. Three-way ANOVA for repeated measures revealed that there was no significant interaction between erosive challenge and CO2 laser irradiation (P = 0.419). Erosive challenge significantly increased enamel wear (P = 0.001), regardless whether or not CO2 laser irradiation was performed. There was no difference in enamel wear between specimens CO2 -laser irradiated and non-irradiated (P = 0.513). Under intraoral conditions, CO2 laser irradiation did not control the progression of erosive lesions in enamel caused by citric acid. Microsc. Res. Tech., 2014. © 2014 Wiley Periodicals, Inc.

    ABSTRACT: Objective: The aim of this study was to evaluate the effect of feldspathic ceramic surface cleaning on micro-shear bond strength and ceramic surface morphology. Material and Methods: Forty discs of feldspathic ceramic were prepared and etched with 10% hydrofluoric acid for 2 minutes. The discs were randomly distributed into five groups (n=8): C: no treatment, S: water spray + air drying for 1 minute, US: immersion in ultrasonic bath for 5 minutes, F: etching with 37% phosphoric acid for 1 minute, followed by 1-minute rinse, F+US: etching with 37% phosphoric acid for 1 minute, 1-minute rinse and ultrasonic bath for 5 minutes. Composite cylinders were bonded to the discs following application of silane and hydrophobic adhesive for micro-shear bond strength testing in a universal testing machine at 0.5 mm/min crosshead speed until failure. Stereomicroscopy was used to classify failure type. Surface micromorphology of each treatment type was evaluated by scanning electron microscopy at 500 and 2,500 times magnification. Results: One-way ANOVA test showed no significant difference between treatments (p=0.3197) and the most common failure types were cohesive resin cohesion followed by adhesive failure. Micro-shear bond strength of the feldspathic ceramic substrate to the adhesive system was not influenced by the different surface cleaning techniques. Absence of or less residue was observed after etching with hydrofluoric acid for the groups US and F+US. Conclusions: Combining ceramic cleaning techniques with hydrofluoric acid etching did not affect ceramic bond strength, whereas, when cleaning was associated with ultrasound, less residue was observed.

    ABSTRACT: Abstract Objective: To evaluate the effect of different lubricants on friction between orthodontic brackets and archwires. Materials and Methods: Active (Quick, Forestadent) and passive (Damon 3MX, Ormco) self-ligating brackets underwent friction tests in the presence of mucin- and carboxymethylcellulose (CMC)-based artificial saliva, distilled water, and whole human saliva (positive control). Dry friction (no lubricant) was used as the negative control. Bracket/wire samples (0.014 × 0.025 inch, CuNiTi, SDS Ormco) underwent friction tests eight times in a universal testing machine. Results: Two-way analysis of variance showed no significant interaction between bracket type and lubricant (P = .324). Friction force obtained with passive self-ligating brackets was lower than that for active brackets (P < .001). Friction observed in the presence of artificial saliva did not differ from that generated under lubrication with natural human saliva, as shown by Tukey test. Higher friction forces were found with the use of distilled water or when the test was performed under dry condition (ie, with no lubricant). Conclusion: Lubrication plays a role in friction forces between self-ligating brackets and CuNiTi wires, with mucin- and CMC-based artificial saliva providing a reliable alternative to human natural saliva.

    ABSTRACT: Objective: This in situ study evaluated the effect of CO2laser irradiation to control the progression of erosive and abrasive lesions on previously eroded enamel. Method: Fifty-six bovine incisors enamel slabs (5x3x2.5 mm) had ¼ of the surface covered with resin composite (control area). To create erosive lesion, specimens were immersed in 1% citric acid (pH=2.3; 5 min), 2x/day, for 2 d. Specimens with pre-formed lesions were divided into two groups: CO2laser irradiated (λ=10.6µm; 0.5W, ultrapulse) and non-irradiated. Fourteen volunteers (n=14) wore a palatal device containing two irradiated and two non-irradiated specimen. Volunteers immersed their appliances extraorally in citric acid 3x/day (8a.m, noon, 4p.m) for 5 d. One hour after each erosive challenge, one irradiated specimen and one non-irradiated were brushed using an electrical toothbrush. Enamel wear was determined using an optical profilometer. Result: Two-way ANOVA revealed that there was no significant interaction between erosive-abrasive challenges and CO2 laser irradiation (p=0.614). Laser irradiation did not influence enamel wear (p=0.742). Enamel wear of the specimens subjected to erosion plus abrasion was not different from that verified when erosion only was performed (p=0.626), regardless whether CO2laser was or was not applied. Conclusion: Under the parameters used, CO2 laser irradiation was not able to control the progression of erosive/abrasive lesions.

    ABSTRACT: Objectives This in situ trial study was designed to evaluate whether calcium (Ca) pre-rinse would increase the fluoride (F) rinse protection against enamel erosion. Methods: Fifteen volunteers participated in this split-mouth, 3-phase, crossover design study wearing a palatal appliance containing four sterilized bovine enamel slabs, for 10 days. In the 1st phase, 5 participants followed protocol A: daily rinse with a Ca lactate (CaL, 150 mmol/L, 1 min), followed by F (NaF 12 mmol/L, 1 min). Other 5 participants followed protocol B: daily rinse only with F, while the remainders followed protocol C: no rinse (negative control). Appliances were removed from the mouth and one side of the palatal appliance was exposed to a daily erosive challenge (0.05 M citric acid, 90 s); the other side served as control (deionized water–no erosion). In the 2nd phase volunteers were crossed over to other protocol and in the 3rd phase volunteers received the remaining protocol not yet assigned. Specimens was evaluated for surface loss using an optical profilometer. Results: Repeated-measures three-way ANOVA (p = 0.009) and Tukey's test showed that CaL pre-rinse followed by NaF rinse significantly decreased surface loss of enamel when performed prior to an erosive challenge in comparison with the condition in which NaF only was used. Conclusions: Pre-rinse with CaL may increase the protection exerted by NaF against erosive wear.

    ABSTRACT: The aim of the present study was to evaluate the effect of natural (green tea (Camellia sinensis) GT) and synthetic (chlorhexidine-CLX) metalloproteinase inhibitors on the microtensile bond strength (µTBS) of an etch-and-rinse adhesive to dentin, after 24 h and 6 months of water storage (WS). Thirty human dentin specimens were conditioned with 37% phosphoric acid for 15 s, rinsed for the same amount of time and dried gently. They were then divided into 3 groups, according to the solution to be applied to the dentin surface (n=10): GT, 2% CLX, or NT (none, as control). CLX and GT solution (20 μl) were applied for 60 s and dried gently with absorbent paper. The adhesive system (Adper Single Bond 2, 3M ESPE) was then applied according to the manufacturer's instructions, and a 4-mm composite resin block was built. After 24 h, at 37 °C, resin–dentin blocks were sectioned into 1-mm2 sticks that were assigned into two µTBS test conditions: after being stored in water for 24 h or after 6 months. Data were submitted to repeated-measures two-way ANOVA and Tukey's test, with a 5% significance level. The failure pattern was described in percentage terms. The results showed that the µTBS values in the NT group were significantly higher compared to the GT values. The application of CLX resulted in intermediate µTBS values, which were not statistically different from NT or GT. There was no significant difference between the µTBS values in the two time points of analysis for CLX and GT groups while the NT group showed a significant decrease over time. After 6 months of WS, all groups had µTBS values statistically similar among themselves. It can be concluded that in a short-term evaluation, chlorhexidine showed no interference on bond strength to dentin, while green tea did. After a long-term evaluation, both metalloproteinase inhibitors, chlorhexidine and green tea, were capable of maintaining bond strength stability.

    ABSTRACT: The aim of this in vitro study was to evaluate the microtensile bond strength (µTBS) to dentin of two different restorative systems: silorane-based (P90), and methacrylate-based (P60), using two cavity models. Occlusal enamel of 40 human third molars was removed to expose flat dentin surface. Class I cavities with 4 mm mesial-distal width, 3 mm buccal-lingual width and 3 mm depth (C-factor=4.5) were prepared in 20 teeth, which were divided into two groups (n=10) restored with P60 and P90, bulk-filled after dentin treatment according to manufacturer's instructions. Flat buccal dentin surfaces were prepared in the 20 remaining teeth (C-factor=0.2) and restored with resin blocks measuring 4x3x3 mm using the two restorative systems (n=10). The teeth were sectioned into samples with area between 0.85 and 1.25 mm2 that were submitted to µTBS testing, using a universal testing machine (EMIC) at speed of 0.5 mm/min. Fractured specimens were analyzed under stereomicroscope and categorized according to fracture pattern. Data were analyzed using ANOVA and Tukey Kramer tests. For flat surfaces, P60 obtained higher bond strength values compared with P90. However, for Class I cavities, P60 showed significant reduction in bond strength (p<0.05). No statistical difference between restorative systems was shown for Class I cavity model (p>0.05), or between Class I Cavity and Flat Surface group, considering P90 restorative system (p>0.05). Regarding fracture pattern, there was no statistical difference among groups (p=0.0713) and 56.3% of the fractures were adhesive. It was concluded that methacrylate-based composite µTBS was influenced by cavity models, and the use of silorane-based composite led to similar bond strength values compared to the methacrylate-based composite in cavities with high C-factor.

    ABSTRACT: To evaluate the effect of dentin pretreatment with 2.5% titanium tetrafluoride (TiF4) on microtensile bond strength (microTBS) of one- or two-step self-etching adhesive systems. 24 human sound third molars were used. A flat dentin surface of each tooth was exposed. After planing, teeth were divided into groups so that dentin would be left untreated or treated with a 2.5% TiF4 solution for 1 minute. Specimens were then subdivided into two groups to receive one of the following adhesive systems: one-step self-etching Adper Easy One (ADP) or two-step self-etching adhesive Clearfil SE Bond (CLEAR). A block of composite measuring 5.0 mm high and 5.0 mm wide was made incrementally on the tooth. Specimens were taken to a metallographic cutter to fabricate sticks with a bond area of approximately 1 mm2. After 24 hours, specimens were submitted to microTBS testing and the failure mode was recorded by examining specimens under stereomicroscopy. Scanning electron microscope (SEM) photomicrographs were obtained of the tooth/restoration interface. Two-way ANOVA and Tukey's test demonstrated that pretreatment of dentin with a TiF4 solution did not affect the microTBS values of either of the adhesive systems (P = 0.675). CLEAR provided higher bond strength than ADP, regardless of whether dentin was or was not pretreated with the TiF4 solution. Failure mode showed mostly adhesive failures in all groups, except when only ADP was used, causing mostly cohesive fractures in resin.

    ABSTRACT: Objectives: In general, orthodontic treatment places patients at increased caries risk. However, to date, no studies have yet been conducted to verify whether such patients would also be under increased risk of dental erosion. This clinical trial was undertaken to compare salivary pH kinetics of participants undergoing (or not) orthodontic treatment after intake of an acidic beverage. Methods: After approval by the local ethics committee, 20 participants undergoing fixed orthodontic treatment and 20 control counterparts were enrolled and had their whole saliva assessed for flow, pH and buffer capacity. According to a crossover layout, participants imbibed orange juice (15mL, pH 3,6) and water added of 5% sucrose (control beverage, 15mL, pH 6,0) in alternate arms. Participants spitted saliva-beverage mixture immediately after, every each 15s intervals up to 1min, then after every 30s up to 5min and finally after 6 and 7min. pH of such collected samples was measured with a calomel pH microprobe. Results: No difference was found between salivary flow, pH and buffer capacity of participants wearing or not wearing orthodontic appliance as shown by Student’s t tests. Three-way ANOVA for repeated measures and Tukey’s test demonstrated that regardless of the time elapsed from the water imbibement, salivary pH was similar for both orthodontic appliance wearers and non-wearers. Among the latter, salivary pH was significantly reduced by the orange juice intake throughout 60s (remaining 30s under critical pH of hydroxyapatite), while in participants wearing orthodontic appliance pH was significantly lower up to 210s (remaining 60s below critical pH of hydroxyapatite). Conclusions: Salivary pH recovery after acidic beverage intake is slow in fixed orthodontic patients, which may put them on higher risk of dental erosion.

    ABSTRACT: BACKGROUND: This study is an analysis of the prevalence of polymorphous low grade adenocarcinoma (PLGA) in epidemiological surveys of salivary tumors published in the English language from 1992 to 2012. METHODS: These surveys included studies from different researchers, countries and continents. The 57 surveys for which it was possible to calculate the percentage of PLGAs among all malignant minor salivary gland tumors (MMSGT) were included in this review. RESULTS: The statistical analyses show significant differences in the PLGA percentage by time period, country and continent in the studies included in this review. The percentage of PLGAs among MMSGTs varied among the studies, ranging from 0.0% to 46.8%. PLGA rates have varied over the period studied and have most recently increased. The frequency of reported PLGA cases also varied from 0.0% to 24.8% by the country in which the MMSGT studies were performed. The PLGA percentages also varied significantly by continent, with frequencies ranging from 3.9% in Asia to 20.0% in Oceania CONCLUSION: Based on these results, we concluded that although the accuracy of PLGA diagnoses has improved, they remain a challenge for pathologists. To facilitate PLGA diagnoses, we have therefore made some suggestions for pathologists regarding tumors composed of single-layer strands of cells that form all of the histological patterns present in the tumor, consistency of the cytological appearance and uniformly positive CK7, vimentin and S100 immunohistochemistry, which indicate a single PLGA phenotype.

    ABSTRACT: The aim of this study was to evaluate the effect of sealer application and thermal cycling on the bond strength between tissue conditioners and acrylic resin, and to observe the type of bond failure. Two hundred eighty-eight specimens (10x16x3 mm) were made of an acrylic resin (Lucitone 500, Dentsply) using a metal muffle. Specimens were divided into four groups according to the tissue conditioner (Coe-Comfort, GC or Dentusoft, Densell) used and whether or not a sealer (Eversoft Soft Liner Sealer, Myerson) was applied. Each of the four groups was subdivided into other six subgroups (n=12) to undergo thermocycling for 45, 90, 135, 180 or 210 cycles with a dwell time of 60 s, or to be left non thermocycled (control). Tensile bond strength was measured in a universal testing machine at a crosshead speed of 5 mm/min. Sealant application had no effect on the tensile bond strength of the relined acrylic resin, regardless of the tissue conditioner used (Coe-Comfort: p=0.306 and Dentusoft: p=0.1501). The number of thermal cycles had a significant effect on the tensile bond strength of the relined acrylic resin (Coe-Comfort: p=0.002 and Dentusoft: p<0.001). Both tissue conditioners presented similar bond strength to acrylic resin. For both tissue conditioners, sealer coatings had no influence on bond strength, while different numbers of thermal cycles affected that mechanical property.

    ABSTRACT: This in vitro study aimed to investigate the anti-erosive effect of antacid suspensions applied to enamel after exposure to hydrochloric acid (HCl). Ninety bovine enamel slabs were embedded, flattened, and polished. Reference areas were created and specimens were divided into six groups. They were exposed to 0.01 M HCl (pH 2) for 2 min, followed by immersion for 1 min in one of the following test suspensions: magnesium hydroxide, aluminum hydroxide, magnesium hydroxide/aluminum hydroxide, sodium alginate/sodium bicarbonate/calcium carbonate, or hydrated magnesium aluminate. Artificial saliva was used as a negative control. Specimens were subjected to a total of five cycles of erosion/antacid treatment. Enamel surface loss was measured (in micrometers) by optical profilometry. In addition, baseline and final surface microhardness (SMH) values of enamel were obtained. It was found that antacid suspensions significantly reduced enamel loss, and that similar protection was afforded by all formulations. No differences were observed between the final enamel SMH values among groups. Antacid suspensions counteracted HCl-induced enamel loss, although they were not effective in reducing enamel softening. Mouth rinsing with antacid suspensions after vomiting can potentially represent a promising strategy to counteract enamel loss caused by erosion.

    ABSTRACT: Objective: Besides the irreversible loss of the outermost enamel surface, erosion causes softening, making enamel more prone to mechanical insults. For this reason research efforts have been devoted to the development of strategies to limit the destructive effects of erosive acids. This study was undertaken to gather preliminary data into the potential protective role of antacid suspensions against enamel softening caused by gastric acid. Method: To simulate erosion, embedded/flattened slabs of bovine enamel (3x3x2mm) were exposed to hydrochloric acid (0.01M; pH 2) for 2min. Immediately after, one of the following antacid suspensions was applied on the surface for 1min (n=8): MH-magnesium hydroxide; AH-aluminum hydroxide; MH+AH; SA+SB+CC-sodium alginate+sodium bicarbonate+calcium carbonate; AMS-hydrated aluminum-magnesium sulfate. Control group were exposed to artificial saliva rather than to antacid. In total, specimens were subjected to 5 erosion/antacid sequences. Enamel softening was evaluated by the percentage surface microhardness reduction (%SMHR). Result: Data showed that %SMHR values were in the range of 191 to 240%. ANOVA and Tukey’s test demonstrated that following erosive attacks, applications of antacid suspensions based on MH or AMS provided lower %SMHR than AH or SA+SB+CC. However, %SMHR resulting from any of the antacid suspensions did not differ from that provided by artificial saliva. Conclusion: Antacid suspensions did not outperform saliva in protecting enamel against softening caused by gastric acid.
