Post-operative Sensitivity of a Self-adhesive Restorative Material

Post-operative Sensitivity and Clinical Performance of a Self-adhesive Restorative Material in Posterior Restorations.

Adhesively restoring teeth using a resin-based composite and a modern dental adhesive is now considered a reliable, predictable, and durable procedure. However, adhering resin-based composite in conditions of suboptimal field control or complex cavity configurations remains challenging. In addition, the continuing discussions on the clinical use of dental amalgam and the feasibility of a phase out of the use of dental amalgam in the long term has become a central concern for restorative dentistry and has led to strong efforts to develop a substitute material for amalgam. With the goal of clinically shorter application times and lower technique sensitivity, the development of an advanced self-adhesive restorative tooth-colored restorative materials (ASAR) that no longer need pre-treatment with a separate adhesive have been under investigation. The aim of this study is to assess the post-operative sensitivity following restoration of teeth using a self-adhesive tooth-colored restorative material and to assess its clinical performance in comparison with conventional resin-based composite in posterior restorations
