Dental resin composites generate microparticles and impact on gingival keratinocytes-In vitro study.

Dental resin composites release microparticles when ground with dental burs; these particles adhered to gingival cells and triggered inflammation without reducing cell survival, though particle size varied depending on the material and grinding method used.
