Abstract

Microleakage of composite restoration in proximal surfaces often occurs at the gingival wall. The purpose of this study was to analyze the microleakage at gingival wall in composite restoration using cocured and precured techniques with conventional and modified liner. Standardized class II cavities were prepared on 120 extracted human upper premolar mesial and distal fossae and categorized into 4four groups. Within box-like cavities, Group 1 was restored using a precured technique (conventional & modified liner), Group 2 was restored using a cocured technique (conventional & modified liner), Group 3 was restored using conventional liner (precured & cocured techniquea), and Group 4 was restored using modified liner (procured and cocured techniques). The specimens were subjected to thermocycling, followed by immersion in 1% methylene blue dye for 24 h. The teeth were sectioned mesiodistally and evaluated for microleakage under 25× magnification using a stereo microscope and scored using an ordinal scale (0-3). Statistical analysis was performed with the Kolmogorov-Smirnov test. Microleakage in Group 2 was significantly lower than Group 1 (p = 0.047). There was no significant difference between Group 3 and 4 (p = 0.985). The cocured technique showed lower microleakage than the precured technique. However, there was no statistically significat difference between conventional and modified liners.
