The objective evaluate was the influence of prolonged tooth bleaching with 10 % carbamide peroxide (10CP) on enamel mass variation. Ten healthy bovine incisor teeth were divided (n = 5) into G1 - storage in distilled water and G2 artificial saliva. samples weighed an electronic analytical balance at following times: T0 before application gel, T1 after 14 days (the time recommended by manufacturer), T2 21 (50 increase T3 28 (100 manufacturer). data subjected to ANOVA for related (p 0.05)....
Background: Dental bleaching has been increasingly sought out to improve dental aesthetics, but it may cause changes in enamel. Objective: To assess the influence of different time intervals on gel applications with regard Microhardness (MH) and Surface Roughness (SR) Material Methods: Forty bovine incisors were randomly divided into two groups (G1 G2) both bleached 35% Hydrogen Peroxide (HP35) (n=20; G1: seven-day interval G2: two-day interval). The MH SR tests performed before (T0) after...
The objective of this in vitro study was to assess the influence prolonged bleaching pre- and postrestoration on bond strength (microshear) enamel using 4% hydrogen peroxide (PH4). In postrestorative bleached specimens evaluation, composite cylinders were assembled after bleaching, while prebleached specimens, before. Therefore, postbleached 60 bovine teeth randomly assigned as follows: G1: control; G2: 14 days before (BS) testing; G3: 21 days; G4: 28 days. 180 G5: storage artificial saliva...
Objective: This work aims to report a clinical case that performed the aesthetic rehabilitation of patient through integration different dental specialties (Orthodontics, Periodontics and Dentistry). Case Report: An 18-year-old female received compensatory orthodontic treatment for correction class II malocclusion, overbite overjet, interproximal diastema. After treatment, gingivoplasty was remove excess gingival tissue increase crown teeth, frenectomy anomalous labial frenulum removal....
Background This study aimed to evaluate the effects of dental polishing and topical application neutral fluoride after bleaching with 35% hydrogen peroxide (HP35%) without remineralizing bioactive components in its composition on surface roughness (SR) tooth enamel. Material Methods Fifty healthy bovine incisors were divided into five groups (n=10 each): G1, treatment (only stored artificial saliva); G2, HP35%; G3, HP35% + diamond paste; G4, whitening fluoride; G5, paste fluoride. SR...
The aim of this study was to compare the bonding strength dental materials in buffalo (Bubalus bubalis var. kerebau), bovine, and human enamel susceptibility these substrates acid etching.A total 20 third molars, bovine incisors, incisors were used a mechanical assay microshear. demineralized via conditioning with 37% phosphoric acid, ultra-morphological pattern each substrate analyzed by scanning electron microscopy.The results showed that there no significant difference adhesive values...
