As resinas de baixa viscosidade na técnica injetável ganharam espaço na Odontologia por serem um material mais econômico e conservador quando comparadas com os laminados cerâmicos e com técnicas que dispõem de maior tempo clínico. A técnica envolve enceramento dentário e confecção de uma matriz de silicone transparente, onde foi injetada a resina B...

Atualmente o grande apelo pela estética tem levado a odontologia moderna ao desenvolvimento de novos materiais e técnicas restauradoras. O presente estudo tem por objetivo avaliar a translucidez de matrizes em silicona de PVS (Polivinilsiloxano) transparente, a serem utilizadas em restaurações obtidas por injeção de resina. Trata-se de um estudo la...

Com a constante evolução e desenvolvimento de novos materiais e técnicas, a Odontologia adesiva vem conquistando grande espaço nas mais diversas especialidades. Em casos de dentes tratados endodonticamente, há uma necessidade na maioria dos casos, de procedimentos restauradores mais complexos, muitas vezes com pinos intrarradiculares para o aumento...

Purpose: To evaluate the use of oxalic acid in restorations of noncarious cervical lesions. Materials and methods: Twenty volunteers of both sexes between 24 and 55 years old, with at least two lesions that were restored with the techniques to be evaluated, were selected. Ninety teeth were randomly divided into two groups: group 1, two-step etch...

Objective: The aim of this study was to evaluate the efficiency of oxalic acid (BisBlock) on restorations of non-carious cervical lesions. Materials and methods: One operator placed 90 restorations randomly divided into two groups in 20 patients under cotton rolls isolation: Control Group-two-step etch-and-rinse adhesive technique; and Experimen...

An excessively acidic diet results in the progressive deterioration of dental health, with functional, esthetic, and biological consequences. Previously, rehabilitation required placing numerous full crowns and root canal treatments; however, with improved adhesive techniques, a more conservative approach may be utilized to preserve tooth structure...

The aim of this study was to evaluate the influence of ceramic surface treatments and silane drying temperature on the microtensile bond strength (µTBS) of a resin composite to a lithium disilicate ceramic. Twenty blocks (7x7x5 mm) of lithium disilicate-based hotpressed ceramic were fabricated and randomly divided into 4 groups: G1: acid etching wi...

To establish a new model of zymosan-induced temporomandibular joint (TMJ) arthritis in the rat and to investigate the role of nitric oxide. Inflammation was induced by an intra-articular injection of zymosan into the left TMJ. Mechanical hypernociception, cell influx, vascular permeability, myeloperoxidase activity, nitrite levels, and histological...

The aim of this study was to evaluate the efficacy of two desensitizing agents in the reduction of dentin hypersensitivity in a randomized, double-blind, split-mouth clinical trial. Seventy-seven teeth from 13 patients that presented some degree of sensitivity to probing and/or air stimulation were treated with one of the following desensitizing ag...
