Three-Year Clinical Performance of a Universal Adhesive in non-Carious Cervical Lesions.
Objectives: The aim of this randomized controlled clinical trial was to evaluate the 3-year clinical performance of a universal adhesive (Clearfil Universal Bond Quick (CUBQ); Kuraray Noritake), using two different application modes (etch-and-rinse vs self-etch with prior selective enamel etching), when restoring non-carious cervical lesions (NCCLs).
Methods: Fifty-one patients participated in this study. A total of 251 NCCLs were assigned to two groups: 1. CUBQ in the etch-and-rinse mode (n=122)(CUBQ, ER) and 2. CUBQ in a self-etch mode with prior selective etching of enamel with phosphoric acid (n=129)(CUPQ, SEE). The same resin composite Clearfil Majesty ES-2 (Kuraray Noritake) was used for all restorations. The restorations were evaluated at baseline, 1 and 3 years using FDI criteria: marginal staining, fracture and retention, marginal adaptation, postoperative sensitivity and recurrence of caries. Statistical analysis was performed using a logistic regression model with generalized estimating equations (2-way GEE model).
Results: The patient recall rate at 3 years was 90%. At this recall, the overall success rate was 84% and 83 % for CUBQ-SEE and CUBQ-ER respectively. In total, 38 restorations (19 CUBQ-ER, 19 CUBQ-SEE) failed because of loss of retention, fracture, severe marginal defect and/or discoloration. A retention rate of 87% and 86% was recorded for CUBQ-ER and CUBQ-SEE, respectively. No significant difference was observed between the two groups for any of the evaluated parameters.
Conclusions: After 3 years of clinical service, Clearfil Universal Bond Quick performed similar in an etch-and-rinse mode and in a self-etch mode with prior selective enamel etching.
