Abstract

Purpose: To evaluate in situ the anticariogenic effect of fluoride and MDPB containing adhesive systems at the restoration interface, by microhardness tests. Methods: 120 fragments containing preparations for resin composite restorations performed at the cemento-enamel junction were randomly distributed among the adhesive systems to be tested. The adhesive systems were applied in accordance with the manufacturers' instructions: Optibond FL, Adper Single Bond 2, Prime \& Bond 2.1, Optibond Solo Plus, Adper Prompt, Clearfil Protect Bond and restored with the nanoparticulate resin composite Z350. Twenty volunteers used a palatal appliance containing fragments restored with each adhesive system for 21 days, and applied 20% sucrose on them eight times a day to simulate a high cariogenic challenge. Microhardness tests were performed at different depths (20 mu m, 40 mu m and 60 mu m from the occlusal margin of the restoration) and at different distances (100 mu m, 200 mu m and 300 mu m from the adhesive interface). Results: ANOVA showed that for enamel, there was significant difference between the adhesive systems (P= 0.0106); the interaction adhesive system{*}distance was a significant (P= 0.0006), and the one-step self-etching adhesive system containing fluoride (Adper Prompt) presented a higher anticariogenic effect. However, for dentin, the adhesive system used did not interfere in decreasing the severity of caries formation. (Am J Dent 2010;23:75-80). (AU)
