Do ozone and boric acid affect microleakage in class V composite restorations

摘要: ABSTRACTThe aim of this in vitro study was to evaluate the effects chlorhexidine gluconate (2%), sodium hypochloride (2.5%), ozone gas, and boric acid at different concentrations (1%, 3%, 5%, 7%) on microleakage from composite restorations.In a total 80 extracted human canine teeth, class V cavity opened buccal surface samples were separated into eight groups. In control group, no procedure applied for disinfection, then restoration (Z250, 3M) made using single-stage, self-etch adhesive (Single Bond 3M). other groups, seven disinfectants used, restored. The teeth split two buccolingual direction, parallel long axes. Stain penetration examined under stereomicroscope scored. Examination with SEM one sample each selected random.
