Evaluation of cuspal deflection and microleakage of an incrementally packed versus a low shrinkage bulk-fill nanohybrid resin composite: an in-vitro study.

Researchers compared incremental and bulk-fill resin composites in MOD restorations, finding bulk-fill produced less cuspal deflection but similar microleakage levels; thermocycling increased microleakage in both materials.
