Comparison of microleakage of three acid-base luting cements versus one resin-bonded cement for Class V direct composite inlays.

Statement Of Problem: Demineralized dentin beneath set cement may adversely affect microleakage under fixed restorations.

Purpose: Microleakage of direct composite inlays cemented with acid-base cements and a methyl methacrylate resin cement were evaluated to determine their effect on the integrity of the underlying hybridized dentin.

Materials And Methods: Sixty Class V box preparations (3 mm x 3 mm x 1.
