Abstract
Section titled âAbstractâAbstract Adhesive bond strength at the composite/dentin interface is influenced by various factors, including the etching mode and composite resin type. The purpose of this study was to evaluate the influence of the totalâetch and selfâetch mode on the microtensile bond strength (ÎŒTBS) of conventional and bulkâfill composite to dentin, using the universal adhesive system. Sixty nonâcarious human teeth were sectioned parallel to their longitudinal axis, using a lowâspeed diamond saw to obtain a flat dentin surface. According to the etching technique and composite resin type used, teeth were randomly divided into four different groups ( n = 15): TC (totalâetch/conventional composite), TB (totalâetch/bulkâfill composite), SC (selfâetch/conventional composite), and SB (selfâetch/bulkâfill composite). Cylindric composite buildâups were made with 3M Filtek Z250 and 3M Filtek Bulkfill Posterior, using a plastic mold, 4 mm in diameter and 4 mm in height. The specimens were subjected to the ÎŒTBS test in a universal testing machine and failure force was recorded. Failure modes were determined using stereoscopic and scanning electron microscopy. Data were analyzed using the twoâway ANOVA and Studentâs t test. The ÎŒTBS was significantly affected by the etching technique. A significant statistical difference was determined between totalâetch and selfâetch groups, irrespective of the composite resin type used. Higher bond strength was obtained in totalâetch groups. The ÎŒTBS was not affected by the composite resin type. No significant statistical difference was determined between the conventional and bulkâfill groups, irrespective of the etchingâmode.
