The Influence of Different Filling Materials and Techniques on the Microleakage of Cervicle and Occlusal Margins in CLII Cavities

Abstract

Esthetic filling is the preference of population but because of the immediate sensitivity and late color change that is related to the microleakage, many new techniques and material used to overcome and improve these shortcomings Aim: The aim of this study is to evaluate and compare microleakage at occlusal wall and cervicle wall in proximal cavities restored with bulkfill and bulkflowable +universal composite Material and method: 20 freshly extracted teeth were divided into 2 groups of 10 teeth each.standared clII cavities were made on mesial surface of each tooth and restored with( bulkfill) and( bulkflowable with z350xt) ,after storage and thermocycling and immersion in dye. Specimen were sectioned and evaluated for micrleakage at occlusal and cervicle wall using electric microscope Statistical analysis: Using : mean , median, standard deviation with the min. and max. Using student t- test and mann whitney t-test were doneResult: The results showed that in the occlusal wall and cervicle wall, bulk fill composite shows significantly less marginal microleakage than bulkflowable and universal composite.Conclusion: Based on the result of this study bulkfill composite showed less microleakage than bulkflowable in both the cervical region and occlusal region
