Abstract

Bulk fill composite resin is a composite resin which developed to filled 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 to compare the microleakage of various bulk fill composite resin filled in class I cavity with bulk technique. Thirty two human maxillary premolars were stored in distilled water. The teeth 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, and group 2, 3, and 4 with bulk fill composite resin. Samples were 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. Samples were sectioned with separating disc. Microleakage were measured by Digital USB Microscope with 100x magnification in milimeters from occlusal-pulp wall. 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 significantly different between group 3 and 4. It can be concluded that bulk fill composite resin with specific initiator component has the lowest and significant microleakage value.
