Primary Outcome Measures

Name	Time	Method
Postoperative Sensitivity: For this evaluation, participants will be questioned about spontaneous post-operative sensitivity using the numerical rating scale of 0-4 (0 = absent, 1 = mild, 2 = moderate, 3 = considerable, 4 = severe) and the visual analogue scale (VAS) of 0-10 and 0-100 after 24 h, 7 and 30 days. The restorations will also be evaluated clinically after the final polishing (one week) and in the periods of 6, 12, 24 and 36 months.
