Effect of methods of tooth enamel preparation on the retentive strength of acid-etch composite resins

The effect of three procedures of preparing enamel surface on the retentive strengths of Concise Enamel Bond. Adaptic acid etch, Restodent and Nurva-Seal/Nurva-Fil was investigated. Resins using an unfilled-filled resin combination(Concise Enamel Bond, Adaptic acid etch, and Nurva-Fil) had a significantly higher retentive strength when the enamel was prepared with a coarse diamond bur than when the surface was unprepared or prepared with a carbide bur. The different procedures of tooth preparation did not affect the retentive strength of the resin when only filled resin was used (Restodent).
