Abstract

Background: Clinical evaluations as fundamental method to prove the efficiency of restorative materials.

Aim: This study evaluated the clinical performance of restorative systems during 2 years of clinical service.

Materials and methods: This study assessed the clinical performance of restorative systems (Filtek Z250 and P60), during 2 years of clinical service, using the US Public Health Service system. The randomized and double-blind study comprising thirty volunteers. The restorations were evaluated at baseline, 6, 12, and 24 months. It was used the following criteria: marginal discoloration (MD), marginal integrity (MI), superficial texture (ST), wear (W), postoperative sensitivity (PS) and recurrent caries (RC).

Results: Statistic analysis was performed using Fisher's and McNemar's exact tests and Pearsons's Chi-square in a significance level of 5%. The results at baseline and 24 months for Group I were: MD - 100, 100%; MI - 100, 88.6%; ST - 100, 94.3%; W - 100, 94.3%; PS - 100, 100%; RC - 100, 100%, of alpha scores; Group II: MD - 100, 97.1%; MI - 100, 91.4%; ST - 100, 94.3%; W - 100, 91.4%; PS - 100, 100%; RC - 100, 100%, of alpha scores. It was observed no statistical difference in the evaluated criteria and period.

Conclusions: After 24 months of evaluation, both restorative systems exhibited acceptable clinical performance.
