ABSTRACT Purpose: To evaluate the effect of low and highly concentrated bleaching agents on microhardness surface roughness bovine enamel root dentin. Methods: According to a randomized complete block design, 100 specimens each substrate were assigned into five groups be treated with containing carbamide peroxide (CP) at 10% (CP10); hydrogen (HP) 7.5% (HP7.5) or 38% (HP38), combination 18% HP 22% CP (HP18/CP22), for 3 weeks. The control group was left untreated. Specimens immersed in...
Most studies dealing with the caries preventive action of Nd:YAG laser have been done in permanent teeth and on primary are still lacking. The aim this study was to evaluate vitro effect combined or not fluoride sources acid resistance tooth enamel after artificial induction by assessing longitudinal microhardness demineralization depth. Sixty blocks obtained from buccal/lingual surface exfoliated human molars were coated nail polish/wax, leaving only a 9 mm² area exposed outer surface,...
The effects of tooth brushing could affect the long-term esthetic outcome composite restorations. This study evaluated effect two different emission spectrum light-curing units on surface roughness, roughness profile, topography and microhardness bulk-fill composites after in vitro toothbrushing. Valo (multiple-peak) Demi Ultra (single-peak) curing lights were each used for 10s to polymerize three resin composites: Filtek Bulk Fill Posterior Restorative (FBF), Tetric EvoCeram (TET) Surefil...
Root caries is an oral health condition characterized by the demineralization of root surfaces teeth. It particularly common among elderly populations. Lasers have proven to be quite effective in treating caries, with varying effects depending on laser parameters and target tissue. Thus, aim this article was evaluate influence Er,Cr irradiation 980 nm diode application, or without fluoride treatment, microhardness dentin. Eigthy-bovine incisors were selected (4mm x 4mm 3mm-thickness) divided...
This crossover study aimed to investigate abrasion of previously eroded hard dental tissues by a whitening dentifrice compared regular dentifrice. After 3-day lead-in period, 14 volunteers were randomly assigned use one the toothpastes while wearing removable appliance, containing 3 enamel and root dentine slabs on each side. On first day salivary pellicle was allowed form. Twice daily for following days, side appliance immersed in an acidic carbonated drink ex vivo other remained unexposed....
The use of erbium lasers to prevent caries in enamel has shown positive results. However, it is not known if Er,Cr:YSGG laser can also be used increase acid resistance root dentine, which another dental tissue susceptible the action cariogenic bacteria.To analyze effects (λ=2.78 μm, 20 Hz) irradiation associated with 2% neutral sodium fluoride (NaF) dentin demineralization.One hundred human samples were divided into 10 groups (G) and treated as follows: G1: no treatment; G2: NaF; G3: (4.64...

Materials Methods: A light-curing composite resin (Filtek Supreme Ultra [FSU]), two hybrid...
The aim of this study was to evaluate by atomic force microscopy (AFM) the early phases and evolution dental enamel erosion caused hydrochloric acid exposure, simulating gastroesophageal reflux episodes. Polished bovine slabs (4x4x2 mm) were selected exposed 0.1 mL 0.01 M (pH=2) at 37 ?#61472;?#61616;C using five different exposure intervals (n=1): no (control), 10 s, 20 30 s 40 s. area analyzed AFM in 3 regions measure roughness, surface morphological surface. data qualitatively.

Abstract The aim of the present in vivo study was to evaluate bacterial contamination sports mouthguards, surface roughness, and efficacy chlorhexidine gluconate spray disinfection these devices. A randomized, blinded cross-over clinical trial performed with twenty 9 13 years old children who practiced martial arts participated all phases study. They were instructed wear mouthguards 3 alternated days a week for 1 hour and, after use, sterile tap water or 0.12%. analyzed by MTT assay,...
