Evaluation of Microleakage in Class V Restorations with Three different Adhesive Systems.

AIM This study was conducted to evaluate the microleakage of class V cavities restored with composite resin and different adhesive systems. MATERIALS AND METHODS In this experimental epidemiological investigation, a total of 75 freshly extracted human teeth were collected. The teeth were randomly divided into three groups (n = 25). Three different intermediate adhesive materials (Clearfil SE Bond, Single Bond, and Xeno III) were used for each group. RESULTS On testing without the application of occlusal load, the maximum microleakage was seen for group III (Xeno III) followed by group I (Clearfil SE) and then group II (Single Bond). On application of occlusal load, the maximum micro-leakage was seen for group III (Xeno III) followed by group II (Single Bond) and then group I (Clearfil SE Bond). The data were analyzed statistically using Kruskal-Wallis and Mann-Whitney U test. CONCLUSION Group III showed the maximum amount of micro-leakage both with and without occlusal load. CLINICAL SIGNIFICANCE All adhesives under investigation exhibited a certain amount of microleakage in enamel and dentin.
