The purpose

This randomized clinical trial evaluates the clinical performance of a new two-component self-etch universal adhesive, OptiBond XTR, when applied in non-carious Class V cervical lesions without macromechanical retention (retentive grooves or bevels). The control material is OptiBond FL, a "traditional" etch/prime/bond adhesive with documented clinical performance. Eighty non-carious Class V cervical lesions are divided into two groups to be treated with either OptiBond XTR or OptiBond FL. Both adhesives are applied strictly according to the manufacturer's directions. Herculite Ultra, a nano-hybrid resin-based composite, is used as the restorative material with both adhesives. The restorations will be evaluated at insertion (baseline), 6 months, and 18 months. An optional three-year recall evaluation is also proposed. The investigators hypothesize that both adhesives will have comparable performance.
