Abstract

This study determined the effect of cleansing solutions on microtensile bond strengths of self-etch adhesives to saliva-contaminated dentin. Seventy five human molars were ground flat to expose mid-depth dentin, and randomly assigned to 5 groups (n=15): no contamination, saliva contamination without cleansing, saliva and cleansing with water, saliva and cleansing with 2% chlorhexidine, and saliva and cleansing with 5% sodium hypochlorite. One third of the specimens in each group (n=5) were bonded with Adper Prompt L-Pop (all-in-one self-etch adhesive), one third with Adper Easy Bond (all-in-one self-etch adhesive), and one third with Clearfil SE Bond (self-etch primer system). Specimens were restored with composite, and processed for microtensile bond strength testing (5-6 rods/tooth). The cleansing solutions were able to cleanse saliva-contaminated dentin without adversely affecting the bond strengths of the self-etch adhesive systems. Our study showed that self-etch adhesive systems are not negatively affected by saliva contamination.
