Minimally invasive restorative techniques can be applied with direct resin composites. However, the preparation for an indirect restoration tends to lead to over-treatment of the tooth structures. A resin-coating technique has been proposed in which both a hybrid layer and a tight sealing film are produced on the dentin surface with a dentin adhesive system and a low viscosity micro-filled resin. It covers and protects the prepared dentin immediately after cavity preparation, and minimizes pulp irritation and post-operative sensitivity. In addition, the resin coating technique enables good bonding of the resin cement and adaptation of composite inlays. The following case report describes treatment involving the resin coating technique in order to achieve minimal intervention for an indirect resin composite restoration.
