| Summary: | Aim: this study evaluated postoperative sensitivity in patients with silorane based composite restorations under different adhesion protocols. Methodology: this was a clinical trial with a controlled, randomized, longitudinal design. The study included 26 patients recruited from those who appeared routinely at the university dental clinics. Each restoration chosen as a sample unit was made following one of the following three adhesion protocols: G1 (control 1) - Surface treatment with self-etching adhesive system Adper SE Plus 3M/ESPE Filtek P60® + 3M/ESPE; G2 (control 2) – Surface treatment with self etching adhesive system P90 3M/ESPE + Filtek P90® + 3M / ESPE; G3 (test) - surface treatment with 37% phosphoric acid + P90 adhesive system 3M/ESPE Filtek P90® + 3M/ESPE; G4 (test) - Surface treatment by blasting with aluminum oxide + P90 adhesive system 3M/ESPE + Filtek P90® + 3M / ESPE. Two trained examiners evaluated the restorations for postoperative sensitivity right after the treatment (baseline) and after 12 months. The restorations were assigned the classifications for the clinical evaluation method proposed by the FDI World Dental Federation. The normal distribution of the data was verified for each dependent variable, using the Kolmogorov-Smirnov test (p ≤ 0.05). The Kruskal-Wallis test was used to identify significant differences in postoperative sensitivity among the treatment groups at baseline and after one year. Results: a total of 123 restorations were made and evaluated in 12 months. Among these, 98% were classified as “clinically very good,” and no significant statistical differences were found among all the tested adhesion strategies. Conclusion: the additional use of phosphoric acid or aluminum oxide blasting in combination with adhesive systems did not influence postoperative hypersensitivity rates |
