Abstract

The aim of this study is to evaluate the use of chlorhexidine in different excipients on the microtensile bond strength of 2-step etch-and-rinse adhesive systems. For this study will be selected 96 sound human molars divided into 12 groups (n = 8). The occlusal surfaces of the molars will be removed with a low-speed diamond saw to expose flat dentin surfaces. Different adhesive systems [Single Bond 2 (3M ESPE, St. Paul, MN, USA), Prime & Bond NT (Dentsply, Milford, DE, USA) and Excite (Ivoclar Vivadent, Schaan Liechtenstein)] will be applied on the previously etched dentin (phosphoric acid 35% - Ultradent Products Inc., South Jordan, Utah, USA) after one of the following dentin treatments: dentin saturated with water; dentin impregnated with chlorhexidine in water; dentin saturated with ethanol; dentin impregnated with chlorhexidine in ethanol. The bonding systems will be applied according to the manufacturer's instructions and will be followed by composite application. After a storage period of 7 days in artificial saliva at 37oC, microtensile test will be carried out using a universal testing machine at 0.5mm/min. The results will be submitted to appropriate statistical tests, depending on data distribution.
