Abstract

A good marginal adaptation of a restoration can be measured by the absence of microleakage at the interface area. Resin composite undergo contraction during polymerization which may result in microleakage The purpose of this study was to analyze the microleakage of class I cavity preparations that were filled with sonic-activated bulk-fill resin composite, bulk-fill resin composite without sonic activation, and composites that were filled incrementally Standardized class I cavities were prepared in 27 extracted human upper premolars and randomly assigned to three groups. The first group was filled with sonic-activated bulk-fill resin composite; the second group was filled with bulk-fill resin composite without sonic activation; and the third group was filled incrementally. The specimens were subjected to: thermocycling; immersion in 1% methylene blue dye for 24 hours; sectioning longitudinally; evaluation of microleakage under a 12 x magnification stereomicroscope; and scoring on an ordinal scale (0-4). Statistical analysis was performed with a Kolmogorov-Smirnov test. There were no statistically significant differences among the three groups. Class I cavity preparations that were filled with resin composites incrementally have less microleakage compared to both sonic-activated bulk-fill and bulk-fill without sonic activation.
