6-month clinical performance of a universal adhesive on non-carious cervical lesions: self-etch and etch-and-rinse techniques

Detalhes bibliográficos
Resumo:	Abstract Objectives: The purpose of this study was to evaluate the 6-month clinical performance of Adhese Universal applied with two different application strategies (self-etch vs. etch-andrinse technique) when restoring non-carious cervical lesions. Methods: Twenty-six patients participated in this study. Restorations of 117 non-carious cervical lesions were assigned to 2 groups: 1) Adhese Universal in the etch-and-rinse mode (n=59) and 2) Adhese Universal in the self-etch mode (n=58). The same resin composite (Tetric EvoCeram) was used for all restorations. The restorations were evaluated at baseline and at 6 months, using the World Dental Federation criteria. The results were analyzed statistically by the McNemar test (α=0.05 and power of 80%) to compare the differences between baseline and 6 months and a generalized estimating equation to compare the differences between the 2 techniques. Results: No differences were found in restoration performance between the baseline and the end of the 6-month period in the self-etch mode (marginal coloring: p=0.1366; fractures/retention: p=1.000; marginal adaptation: p=1.000; hypersensitivity: p=0.4795; recurrence of caries: p=1.000). On the other hand, in the etch-and-rinse mode, for both fractures/retention (p=0.0028) and marginal adaptation (p=0.0016), significant differences were found. Significant differences were also detected between groups at 6 months for fractures/retention and marginal adaptation (p<0.01). Nine restorations were lost at 6 months in the etch-and-rinse group. Conclusions: The tested universal adhesive obtained better results in the self-etch technique than in the etch-and-rinse technique, both on fractures/retention and marginal adaptation.
