3. Evaluation of the effect of chlorhexidine and sodium hypochlorite in adhesive cementation of fiber posts - in vitro study
Resumo Introdução A fixação de pinos de fibra de vidro é realizada através de um processo adesivo. Falhas podem ocorrer na adesão devido à degradação hidrolítica dos adesivos, ou pela degradação das fibras colágenas da camada híbrida por enzimas intrínsecas. Objetivo Avaliar o efeito do tratamento com clorexidina e hipoclorito de sódio sob

5. Quantitative image of fluorescence of ceramic and resin-cement veneers
Abstract The main of the study was quantify the effect of two ceramics with two underlying resin cements on apparent fluorescence levels. Buccal surfaces of two bovine incisors were ground flat producing one enamel and one dentin substrate. The veneers were fabricated (0.5 and 1.0 mm thickness) using two ceramics (IPSe.max Press and IPSe.max Zirpress, Ivocla

6. The effect of a 3% hydroxyapatite paste prophylaxis after different root-scaling procedures in periodontics
Resumo Introdução Procedimentos de raspagem na superfície radicular aumentam a rugosidade superficial durante a instrumentação. O uso de pasta profilática pode reduzir a rugosidade. Objetivo Este estudo avaliou a influência da profilaxia com pasta na rugosidade superficial da dentina radicular após instrumentação manual (IH), ultrassom (US) e ins

7. Comparison of in vitro erosion protocols in bovine teeth to simulate natural erosion lesion: analysis of mechanical properties and surface gloss
Abstract Objective The aim of this study was to compare two in vitro erosion protocols, in which one simulates in vivo conditions experienced by patients with gastroesophageal disorders or bulimia (HCl-pepsin protocol), and the other simulates the diet of an individual who consumes a high volume of erosive beverages (citric acid protocol). In addition, the

10. Influence of ethanol-wet dentin, adhesive mode of application, and aging on bond strength of universal adhesive
Abstract The aim of this study was to evaluate the effect of ethanol on the bond longevity of a universal adhesive system to bovine dentin, under different modes of adhesive application and artificial aging. Bovine dentin was exposed, and the smear layer was standardized by sandpaper polishing. Specimens were randomly divided into 2 groups: ethanol (E) and n

11. Chlorhexidine and proanthocyanidin enhance the long-term bond strength of resin-based endodontic sealer
Abstract The aim of this study was to evaluate the effects of proanthocyanidin (PA) and chlorhexidine (CHX) on the bond strength (BS), failure pattern, and resin-dentin interface morphology of the endodontic sealers EndoREZ and AH Plus after 24 h and 6 months of water storage. A total of 120 prepared bovine roots were divided into six groups: AH Plus, CHX+AH
