The wetness of dentin surfaces, the presence of pulpal pressure, and the thickness of dentin are extremely important variables during bonding procedures, especially when testing bond strength of adhesive materials in vitro with the intention of simulating in vivo conditions. The ultimate goal of a bonded restoration is to attain an intimate adaptation of the restorative material with the dental...

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 agents: Oxa-Gel (G1), Sensi Kill (G2) and placebo...

Objective:To determine the differences in efficiency of four desensitizing agents in relieving dentin hypersensitivity in a time period of 2 weeks. Material and methods: 50 participants who responded positively to intraoral testing for dentin hypersensitivity using a split-mouth-designed study were recruited for the study. Sensitivity was assessed by means of thermal and thermal/evaporative sti...

PURPOSE The aim of this study was to evaluate: 1) the effect of five dentin desensitizing agents (DDAs) on permeability using hydraulic conductance, and 2) morphological tubule changes with scanning electron microscopy (SEM). MATERIALS AND METHODS The agents tested were Seal & Protect, Gluma Desensitizer, HurriSeal, D/Sense 2, and Super Seal. Thirty extracted human molars were sectioned into ...

Restorative dentistry is mainly based on good adhesion between restorative materials and dental substrates; while adhesion to enamel is generally reliable, adhesion to dentin is less predictable (1) because of the presence of dentinal tubulis and the perfusion of liquids from it. Adhesion to dentin requires demineralization of peritubular and intertubular dentin to replace the demineralized lay...

PURPOSE To assess the efficacy of a novel stannous-containing dentifrice in the reduction of dentin hypersensitivity when compared to a marketed positive control dentifrice. METHODS An 8-week, single-center, randomized, parallel group, two-treatment, double-blind clinical study was conducted in a generally healthy adult population with moderate thermal and tactile dentin hypersensitivity. A t...

Dentin phosphoprotein (phosphophoryn, DPP) is a unique acidic protein in dentin. Except for type I collagen, DPP is the most abundant extracellular matrix protein in dentin. This protein is characterized by high contents of phosphoserine (45-50%) and aspartic acid (35-38%) (Butler et al., 1995)1). Because of the high levels of aspartic acid and phosphoserine, this protein has polyanionic charac...

Objective Cavity preparation is a surgical procedure that attempts to remove all infected dentin.1 Bacteria left beneath the filling material is greatest threat to the pulp. To reduce the potential for residual caries development and sensitivity, an antibacterial solution with the ability to disinfect the prepared tooth surface would be of help.2 So this study was conducted to evaluate and comp...

Minimally invasive restorative techniques can be applied with direct resin composites. However, the preparation for an indirect restoration tends to lead to over-treatment of the tooth structures. A resin-coating technique has been proposed in which both a hybrid layer and a tight sealing film are produced on the dentin surface with a dentin adhesive system and a low viscosity micro-filled resi...

This case report describes the Indirect Pulp Treatment (IPT) of deep caries lesion in a permanent molar. A 16-year-old male patient reported discomfort associated with thermal stimulation on the permanent mandibular left first molar. The radiographs revealed a deep distal caries lesion, very close to the pulp, absence of radiolucencies in the periapical region, and absence of periodontal space ...
