Biomimetic Restorative Dentistry: an evidence-based discussion of common myths.

This narrative review critically examines some protocols of biomimetic restorative dentistry (BRD), which supposedly outperforms traditional adhesive techniques. This review explores the origins of BRD, introduces cognitive biases influencing the adoption of BRD protocols without evidence scrutiny, and discusses nine BRD protocols. For this, we searched randomized clinical trials and systematic reviews in the literature on the PubMed, Embase, and Cochrane Library CENTRAL databases, which lead to the following conclusions about the revised protocols: 1) The use of dyes excessively removes carious dentin; 2) Aluminum oxide air abrasion contributes to overtreatment and may pose long-term health risks to dental professionals; 3) Beveling enamel in posterior teeth is technically difficult and leads to unnecessary loss of adjacent sound enamel with no evidence of its use outperforming butt-joint preparations; 4) Deactivating matrix metalloproteinases with chlorhexidine shows no clinical evidence of improving restoration longevity.
