How to improve bond stability to eroded dentin: a comprehensive review

Abstract

Dentin erosion is a frequent clinical condition that requires restorative interventions, especially in cases with moderate to severe wear. This requires clinicians to have knowledge about the characteristics of dentin, etiological factors involved, and restorative approaches to be made. Minimally invasive restorations have been indicated for rehabilitation of these cases, in order to preserve the largest possible amount of dental tissue. To achieve this, effective and durable adhesion to the eroded dentin must be obtained. However, the histological and morphological changes resulting from the erosive challenge have make eroded dentin a much more challenging substrate to treat than sound dentin. In order to minimize these limitations, mechanical and chemical strategies, as well as changes in the adhesive protocol, have been reported in the literature. The purpose of this review was to present these limitations and discuss the effectiveness of the strategies suggested, based on the results of bond strength to eroded dentin.
