| Abstract | ||
| Aim of the study to measure the shear bond strength of composite resin bonded to dentin with three different adhesive system.The buccal surfaces of 30 non-carious, intact, extracted upper premolar (Freshly extracted for orthodontic treatment), were grinded with 600 grit silicon carbide paper to expose dentin surface. the samples were divided into three groups: G1, 10 teeth were bonded with an acetone-base total-etch Prime&Bond NT G2, 10 teeth were bonded with an ethanol-base total-etch Excite. G3,10 teeth were bonded with an ethanol-and water-base total-etchSchotchbond 1. Shear bond strength is determined by using Instron testing machine. Resultsshowed that excite adhesive system has statisticallyhighsignificant increase in shear bond strength than Schotchbond 1.As conclusion;the lack of water in the adhesive may play a more important role than the type of solvent itself. | ||
