BIODEGRADATION AND DENTIN BONDING EFFECTIVENESS OF ONE "UNIVERSAL" SELF-ETCH ADHESIVE USED IN MULTI-MODE MANNER

Abstract

A new type of one-step self-etch adhesives classified as "Universal" or "multi-mode" adhesives appeared in recent years. The idea is that these adhesives can be applied simultaneously with both techniques - etch and rinse and with self-etching technique, without compromising the bonding effectiveness. The aim of this study is to evaluate the micro-tensile adhesive bond strength to dentin of permanent teeth achieved after application of Single Bond Universal (3M ESPE) adhesive system used in multi-mode manner. The results of our study show that the use of this universal adhesive system in multi-mode manner will not lead to the same results regarding the achieved bond strength with dentin. The additional etching with 37% phosphoric acid as well as the application of the adhesive in several layers deteriorates the bond strength right after application and after six months storage in artificial saliva medium (SAGF).
