The aim of this study is to evaluate the effect of sodium bicarbonate, glycine and erythritol air polishing on enamel and exposed root surface. Forty eight single root extracted teeth were included into the study. The teeth were divided into three groups, the crown and exposed root surface were air polished using three powders at instrumentation time of 5s, combinations of medium and maximum power and medium water settings, distance of 5mm and angulation of 60 degree. Samples were scanned in a micro-computed tomography (micro-CT) at baseline and then after powder treatment and the defect depth, defect volume, demineralization depth and mineral density values were estimated.
The use of air-polishing device that operates by directing a fine slurry of pressurized air, water, and abrasive particles has become widespread in dentistry for polishing. The introduction of abrasive powders with different properties creates the need to evaluate the effects of these powders on dental hard tissues. This study was focused on the effect of sodium bicarbonate, glycine and erythritol air polishing on enamel and exposed root surface.
