Influence of various air-abrasive powders on the viability and density of periodontal cells: An in vitro study.

Remnants of air-abrasive powders on treated surfaces and tissues may affect tissue healing. The purpose of this in vitro study was to investigate the possible effect of five commercially available air-abrasive powders on the viability and cell density of three types of periodontal cells. A sodium bicarbonate powder, two amino acid glycine powders, an amino acid glycine and tricalcium phosphate powder and an erythritol powder were tested.
