Evaluation of postoperative sensitivity in posterior composite resin restorations: A randomized clinical study

Purpose: The aim of this study is analyse the effect of applying a universal adhesive that can be used with all adhesive techniques with different adhesive techniques (total etch and self etch) and different composite placement techniques (bulk-fill technique and incremental layering technique) on postoperative sensitivity to clinically. Material-Methods: In this clinical study, 140 restorations were performed on 70 patients with primary caries lesions in their premolars. Two restorations were applied to each patient, one from each adhesive technique. The cavities were then completed with the bulk-fill technique using Tetric PowerFill composite resin or the incremental layering technique using G-aenial Posterior conventional composite resin. Postoperative sensitivity was evulated at baseline (day 0), 1, 7 and 14 days using the VAS (visual analog scale) scoring index; evaluated with cold, air and chewing stimuli. Results: No statistically significant difference was observed between the study groups in terms of postoperative sensitivity in tests with cold, air and chewing stimuli. Conclusion: Within the limitations of our study, the universal adhesive resin tested; It was concluded that the use of different adhesive techniques and different composite placement techniques did not affect the postoperative sensitivity.
