Abstract

Objectives: To compare the coronal marginal microleakage three types of available tooth colored restorative materials. Study Design: This in vitro comparative experimental study. Setting: Department of Science of Dental Materials, Sardar Begum Dental College. Period: July 2017 to November 2017. Material & Methods: Marginal micro-leakage of three tooth colored dental restorative materials were evaluated. In this study 55 specimens were divided into five groups, three experimental and two control groups. For experimental groups (I, II, III), 15 specimens each were allocated while five specimens each were allocated to positive control and negative control group. Standard Class I cavities were restored using Self-cured Glass Ionomer (Shofu Inc Japan), Resin Modified Glass Ionomer Cement (Kavitan LC; Spofa Dental Kerr Company) and Posterior Composites (Filtek P60; 3M ESPE). After thermo cycling and immersion in 2% methylene blue dye solution, the teeth were sectioned and the dye penetration depth measurement was done for each specimen with a periodontal probe in mm with the aid of magnifying lens. Analysis of variance (ANOVA) was used to assess the significant difference in coronal marginal microleakage of different materials by using SPSS. Results: It was found that there was a statistically significant difference (p < 0.05) in the micro-leakage of Group II and Group III when compared with group I but no statistically significant difference in the micro-leakage values of Group II and Group III was observed. Conclusion: All the restorative materials were unable to prevent the microleakage completely. Filtek P60 displayed minimum mean microleakage followed by Kavitan LC while the mean microleakage of Self-cured shofu Glass Ionomer was found to be maximum.
