Air abrasion is a dental technique that uses compressed air to propel a thin stream of abrasive particles—often aluminum oxide or silica—through a specialized hand-piece to remove tooth tissue and decay before being suctioned away, similar to sand blasting.
As the speed of a handpiece increases, its torque subsequently decreases (slow-speed handpieces have high torque, whereas high-speed handpieces, like the air turbine system, have a low torque) The free running speed of 1:5 gear ratio electric handpiece is the same as its cutting speed; thus, 40,000 motor speed x 5 = 200,000 rpm burr speed.
Prophylaxis: dental prophylaxis includes the removal of extrinsic staining using a slow-speed rotary handpiece and a rubber cup with abrasive paste, mostly containing fluoride. [21] The abrasive nature of the prophy paste, as it is known, acts to remove extrinsic staining using the action of the slow-speed handpiece and the paste against the tooth.
Technically, a deep dental cleaning involves two procedures: tooth scaling and root planing, Dr. Elbert Tom, assistant clinical professor and group practice director at the UCLA School of ...
In addition to brushing, cleaning between teeth may help to prevent build-up of plaque bacteria on the teeth. This may be done with dental floss or interdental brushes.. 80% of cavities occur in the grooves, or pits and fissures, of the chewing surfaces of the teeth, [4] however, there is no evidence currently showing that normal at-home flossing reduces the risk of cavities in these areas.
Another aspect of the syringe is the capability of use, which means dentists are able to easily insert fluid in the device and follow the color coded instructions that allow for efficient use of the dental instrument. [3] The device is so intricately sized that doctors are able to grip it well enough to get the job done. [3]
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
The New York-based 2nd U.S. Circuit Court of Appeals declined to have the full court reconsider a three-judge panel's October rejection of Halkbank's argument that it deserved immunity from ...
