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

All participants will be informed about the nature and objectives of the study; however, they will not be informed what material they would receive.

Restorative procedure of the teeth will be performed using Filtek-Bulk Fill Posterior Restorative, Bulk-fill resin composite, (3M, ESPE) following application of an etch-and-rinse single bottle adhesive (3M, ESPE).

Restorative procedure of the teeth will be performed using Surefil one™ Self-Adhesive Composite Hybrid (Dentsply, Sirona),

For the evaluation of post-operative sensitivity, participants will be asked to record whether they experienced sensitivity using a 0-4 numerical rating scale (0 = none, 1 = mild, 2 = moderate, 3 = considerable, and 4 = severe). The patients will be asked to fill in the pain scale forms 24 hours after the restorative procedure and daily up to seven days, and at 2 weeks and 1 month intervals.

All restorations will be evaluated at 6 months and 1-year post-restoration using the United States Public Health Service, USPHS criteria using the Alpha, Bravo and Charlie scale to evaluate the following parameters: retention, color match, marginal discoloration, secondary caries, anatomical form, marginal adaptation, and surface roughness.
