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.
