Assessment of microleakage in class II cavities restored with composite resin by using different placement techniques

Abstract

Background: To assess microleakage in class II cavities restored with composite resins by using various placement techniques. Materials and methods: A total of 60 samples were enrolled, 10 in each group. They were divided into 6 groups. Scoring for the degree of dye penetration at the occlusal and cervical walls were evaluated. The results were analyzed using SPSS software. The significance was determined at p-value less than 0.05. Results: Microleakage in occlusal wall mean scores of the 6 groups are depicted. Results for occlusal wall showed significantly better score for groups 3 and 4, when compared to other groups. The mean score for dye penetration in group 1and 2 were 0.21 and 1.0. Conclusion: Flowable composite as the first increment is better to use and hence, recommended in class II cavities.
