Abstract

Introduction: Knowledge of self etch bonding systems with the least amount of microleakage can be a good guidance for choosing a proper adhesive at the time of saliva contamination and reducing fissure sealant working time, especially for children. The aim of this study was to determine the effect of saliva contamination on sealants' microleakage in adhesive systems with different acidity. Materials & Methods: The occlusal fissures of 54 extracted third molars were prepared with 1/4 round bur. Then teeth were randomly divided into 6 groups. Total etch dentin bonding (Adper single bond2), self etch with weak acidity (Clearfil S3 Bond) and self etch with strong acidity (Adper prompt l-pop) were used. The fissures of teeth, after thermocycling and cutting, were examined. The afore-mentioned bondings were used to treat 3 contaminated and 3 noncontaminated groups, followed by the sealing of fissures. Results: Comparison of microleakage between groups revealed a significantly lower amount for the self etch bonding with weak acidity (Clearfil S3 Bond)-both in contaminated and noncontaminated teeth versus strong-acidity-self-etch group (Adper prompt l-pop) (P=0.001). However under these conditions comparing microleakage between self etch and total etch bondings indicated no difference. Conclusion: In the possibility of saliva contamination, the application of weak-acidity-self-etch adhesives (Clearfil S3 Bond) is recommended for fissure sealant therapy.
