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...

Description
Summary: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. Material and Methods. Sixty Class V box preparations (3 mm × 3 mm × 1.5 mm) were precisely prepared in previously frozen bovine teeth with one margin in enamel and another margin in dentin. Direct composite inlays (EPIC-TMPT) for each preparation were divided into 4 groups of 15 specimens each and cemented with 3 acid-base cements (control group): Elite, Ketac-Cem, Hy-Bond Carbo-Cem, and 1 adhesive resin cement: C&B Metabond. All specimens were stored in distilled water for 24 hours at 37° C before immersion in 0.5% basic fuchsin for 24 hours. The dye penetration was measured on the sectioned specimens at the tooth-cement interface of enamel and cementum margins and recorded with graded criteria under light microscopy (Olympus Vanox-T) at original magnification × 50, 100, and 200.
