Postoperative sensitivity evaluation after placement of dental resin restoration when different types of adhesives are used

A randomized, split-month clinical study comparing the short and long-term postoperative sensitivity in composite resin restoration using etch-and-rinse and self-etching adhesive systems placed in large and deep class I and II cavities in molars and pre-molars

Design outcomes

Primary

MeasureTime frame
Non-parametric Kruskall-Wallis analysis was applied to the verified sensitivity results for all adhesive systems within each evaluation period (independent sample), including T0 (the preoperative evaluation), and no significant differences were detected. According to the p-values observed (p=0,53) at each evaluation period, no significant differences could be found.

Secondary

MeasureTime frame
Friedman non-parametric analysis was also applied to the results obtained for each adhesive system at all the evaluation periods (dependent sample), and the p-values (P>0.05) again showed no significant differences
