Sonic application of one-step self-etch adhesive in composite restorations of non-carious cervical lesions: A double-blind randomized clinical trial.

Objectives: To evaluate the influence of the sonic device on the clinical performance of one-step self-etch adhesive systems in non-carious cervical lesions (NCCLs) after 18 months.

Materials And Methods: Forty patients participated in this study. Eighty restorations were assigned to two groups (n = 40): Sonic application and Manual application.
