OBJECTIVES To evaluate the dentin wetting by four adhesive systems and to relate the wetting properties with the adhesive efficiency. METHODS Scotch Bond Multipurpose Plus (3M), Syntac Single-Component (Vivadent), One-Step (Bisco) and Heliobond (Vivadent) were used. The substrate was superficial and deep human dentin. Roughness and water contact angle were measured before and after acid etchi...

The objectives of this research were (1) to analyze the variations of the permeability of dentin after restoration with two polyacid-modified resin composites (Compoglass, Dyract) and four single-bottle adhesives (Prime & Bond 2.0, Syntac Single Component, OptiBond Solo, and Single Bond--Scotch Bond 1 in Europe--immediately (approximately 1 hour) after insertion. A perfusion system with distill...

dentin bonding agents (dba) have been used as root-end filling materials. present study evaluated the effects of polymerized dba on secretion of pro-inflammatory cytokines by normal human monocytes. in this study, monocytes were directly isolated from human peripheral blood, and exposed to cured scotch bond 1 (single bond) and prime and bond for 36 and 72 hours. secretion of il-1β and tnf-α in ...

BACKGROUND Bleaching the discoloured teeth may affect the tooth/composite interface. The aim of this in vitro experimental study was to evaluate the effect of vital tooth bleaching on microleakage of existent class V composite resin restorations bonded with three dental bonding agents. METHODS Class V cavities were prepared on buccal surfaces of 72 intact, extracted human anterior teeth with ...

OBJECTIVE The goal of this paper is to undertake a literature search collecting all dentin bond strength data obtained for six adhesives with four tests (shear, microshear, tensile and microtensile) and to critically analyze the results with respect to average bond strength, coefficient of variation, mode of failure and product ranking. METHOD A PubMed search was carried out for the years bet...
