OBJECTIVES The aims of this study were to evaluate the effect of resin composite (Filtek Z250 and Filtek Flow Z350) and adhesive system [(Solobond Plus, Futurabond NR (VOCO) and Adper Single Bond (3M ESPE)] on the microtensile (μTBS) and microshear bond strength (μSBS) tests on enamel, and to correlate the bond strength means between them. MATERIAL AND METHODS Thirty-six extracted human molar...

OBJECTIVES To assess the effect of lactic acid (LA) on microleakage of silorane-based composite restorations and methacrylate-based composites with self-etch and etch-and-rinse bonding systems. MATERIALS AND METHODS Class V cavities were prepared in 120 extracted human teeth, divided into four groups and restored as follows: 1. Silorane-based composite+P90 adhesive system (P90); 2. Filtek Z25...

 Aim- The aim of this study was evaluate effects five commercially available mouthrinses (Listerine, Colgate plax, Clohex Plus, Orahex Plus Senquel-AD) on color stability three different resin-based composit...

Objetivo: O objetivo deste estudo foi avaliar in vitro a resistência de união através do teste microtração resinas compostas bulk fill tipo flow à dentina da margem cervical cavidades classe II molares humanos recém extraídos. Metodologia: Foram padronizadas 50 com 4 mm profundidade e 3 largura vestíbulo-lingual, na mesial distal 25 molares. As (n=10) foram restauradas as resinas: Filtek Z350XT...

Abstract This study evaluated the chemical composition and microhardness of human enamel treated with an Enamel Matrix Derivative (EMD) solution, bond strength between composite resin this enamel. Thirty samples were randomly divided into three groups: Untouched (UE), Demineralized (DE) Treated EMD (ET). DE ET groups subjected to acid challenge (EMD was directly applied over conditioned left fo...

Introduction: This study aimed to devise customized fixtures for the evaluation of three-point bending strength (TPBS) of resin-based dental composites (RBCs). Materials and Methods: A cube-shaped jig made out of wood with dimensions of 105×105×101 mm was prepared in this study. A 20-mm-diameter hole was made in the center of the wooden jig. In addition, a stai...

The objective of this study was to evaluate the flexural strength (sigma f) and hardness (H) of direct and indirect composites, testing the hypotheses that direct resin composites produce higher sigma f and H values than indirect composites and that these properties are positively related. Ten bar-shaped specimens (25 mm x 2 mm x 2 mm) were fabricated for each direct [D250 - Filtek Z250 (3M-Esp...
