Interfacial micromorphology of three adhesive systems created in caries-affected dentin

Abstract

Purpose: To investigate the morphology of the resin-dentin interface of three dentin adhesive systems (One Coat Bond, Clearfil SE Bond and One-Up Bond F) bonded to caries-affected dentin, exposed using either rotary instrumentation in conjunction with a caries detector dye or a chemo-mechanical caries removal system (Carisolv). Materials and Methods: 60 extracted human molars with occlusal caries were used. 30 teeth had carious dentin removed using slow-speed round steel burs after staining with the caries detector dye, and carious dentin from the remaining teeth was removed using Carisolv. The teeth from each caries removal technique were randomly divided into three groups, bonded with one ..
