Aim: This study was done to evaluate the rate of microleakage in class V amalgam restorations in which the dental bonding agent (DBA) Excite was used as a sealer beneath the restorations. Methods: four amalgam restorative materials with commercial names of Dentam, Cinalux, Tytin and SDI (GS-80) were used. Seventy sound human premolars were selected and randomly divided into 4 groups of 15 teeth...

Introduction: This study evaluated microleakage of flowable and conventional composite in primary molar class II restorations using self-etch and total-etch bonding agents. Methods: Class II standard cavities were prepared on proximal surface of 48 primary molars. These cavities were restored using GrandioFlow and Grandio composites and Futurabond DC and Solobo...

INTRODUCTION The aim of this study was to investigate the proper time to restore composite resin over mineral trioxide aggregate (MTA). METHODS Thirty-five samples of MTA blocks were divided into 7 groups with 3 different times (10 minutes, 1 day, and 7 days) selected for restoring the composite resin over MTA with and without bonding resin, and a control group was included for comparison. Af...

objectives: composite repair is a minimally invasive and conservative approach. this study aimed to evaluate the effect of an additional hydrophobic resin layer on the repair shear bond strength of a silorane-based composite repaired with silorane or methacrylate-based composite. materials and methods: sixty bar-shaped composite blocks were fabricated and stored in saline for 72 hours. the surf...

The aim of this study was to investigate the diffusion of red-stained experimental GM primer and blue-stained dentin bonding agent into EDTA-conditioned dentin and the effect of GM priming on contraction gap formation. After GM priming at 0, 35, 70, or 100 vol%, marginal adaptation was evaluated by measuring the wall-to-wall contraction gap width of a light-activated resin composite (Palfique E...
