The Effect of Air Polishing on the Tooth Surface
The Effect of Air Polishing on the Tooth Surface
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.
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.
Inclusion Criteria:

 -  Being older than age of 18,

 -  Willing to participate the study,

 -  To have a single rooted tooth with gingival recession on all surfaces and need to be
 extracted,

 -  The tooth has to be free of caries, defects and restorations.

 Exclusion Criteria:

 Have history of infectious diseases like Hepatitis and/or HIV (+).
