Abstract

Introduction: Bulk fill composite resin developed to applied in a cavity up to 4 mm of depth and shrinkage can be minimized during polymerization. Bulk fill composite resin in its development has a lower microleakage value than conventional composite resin. The aim of this study was to compare the microleakage of three bulk fill composite resin filled in class I cavity with bulk technique. Method: Thirtytwo human maxillary premolars were stored in distilled water. Each tooth was planted into a cast box and class I cavities were prepared. Samples were divided into four groups. Control group was filled with conventional composite resin. Group 2, 3, and 4 was filled with bulk fill composite resin and then stored in an incubator at 37oC for 24 hours. Samples were manually thermocycled for 100 times at 5oC and 55oC, then immersed in 1% methylene blue solution for 24 hours. Microleakage were measured by Digital USB Microscope with 100x magnification in milimeters from occlusal-pulp wall. Result: The result showed that group 2 has the lowest of microleakage value and control group has the highest. Data were analyzed by one-way ANOVA and post hoc LSD test. The result showed that the microleakage value were significantly different among all treatment groups and control group, and between group 2 with group 3 and 4, but there is no significant difference between group 3 and 4. Conclusion: It can be concluded that bulk fill composite resin with specific initiator component has the lowest microleakage value.
