Abstract

This study evaluated the effects of four cavity pre-treatments on the microleakage of a fifth generation adhesive system and accompanying resin composite. Sixty human molars were randomly selected for cavity pre-treatment for the following material groups: Ultra-Etch 35% phosphoric acid gel, Ultra-Etch AB 35% phosphoric acid gel with cetylpyridinium chloride antimicrobial agent, Ultra-Etch 35% phosphoric acid gel followed by Concepsis chlorhexidine gluconate antimicrobial solution, Ultra-Etch 35% phosphoric acid gel followed by Consepsis Scrub chlorhexidine gluconate antimicrobial slurry and no etchant and/or cavity pre-treatment. Circular preparations were cut on the facial or lingual surface of each tooth and treated with the appropriate etchant/cavity disinfectant. PQ1 self-priming adhesive was placed in the preparations followed by Vitalescence resin composite. The molars were thermocycled, sealed with nail varnish, placed in 5% methylene blue dye and sectioned. Leakage was assessed by dye penetration at the occlusal and gingival surface positions of the specimen blocks using a binocular microscope. The Consepsis Scrub and no pre-treatment groups revealed significantly greater leakage than the other groups treated with antimicrobial disinfectants or etchants. No significant differences were shown in the two etchant groups that were compared, Ultra-Etch and Ultra-Etch AB. Significantly greater leakage was not exhibited by the same materials at the occlusal vs gingival surface positions.
