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.

About this study

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.

Who can participate

Only the study team can determine whether someone qualifies for participation.

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 (+).

Treatment and study plan

AIR-FLOW® Master Piezon

Device

AIR-FLOW® Master Piezon is intended for use in the cleaning and polishing of teeth by the projection of water,air, and dental powders onto the tooth surface. The device removes dental plaque, soft deposits, and surface stains from pits, grooves, interproximal spaces, or smooth surfaces of teeth. This air polishing device was used for all powder instrumentations.

Primary outcomes

  1. Defect depth

    Time frame: 5 second

    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 was estimated.

  2. Demineralization depth

    Time frame: 5 second

    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 demineralization depth was estimated.

  3. Mineral density

    Time frame: 10 second

    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 5 mm and angulation of 60 degree. Samples were scanned in a micro-computed tomography (micro-CT) at baseline and then after powder treatment and the mineral density was estimated.

  4. Defect volume

    Time frame: 5 second

    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 volume was estimated.
