Air turbine used in a dental handpiece Correlation between rotational speed and torque Correlation between rotational speed and turbine output power. The turbine is powered by compressed air between 35 and 61 pounds per square inch (~2,4 to 4,2 bar), [1] [2] which passes up the centre of the instrument and rotates a Pelton wheel in the head of the handpiece.
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.
Miscellaneous endodontic instruments. From left: Lentulo spiral, reamer, K-file and H-file. Hand files can provide tactile sensation when cleaning or shaping root canals. This allows the dentist to feel changes in resistance or angulation, which can help determine curvature, calcification and/or changes in anatomy, in which two dimensional radiographs may not always identif
Root canal procedure: unhealthy or injured tooth, subsequent creation of an access cavity with a dental handpiece, cleaning and shaping the root canals with an endodontic file, and restoration with gutta-percha filling and a crown Removing infected pulp during a root canal procedure
A Lentulo spiral. The notches at left allow it to fit into a slow-speed latch handpiece. A Lentulo spiral is a dental instrument used to properly distribute root canal sealer and cement evenly throughout the root canal system, as when performing endodontic therapy or a post and core cementation.
Unlike a routine dental cleaning, the techniques used in a deep cleaning get below the gum line to remove bacteria stuck there. The procedure, which involves local anesthetic to temporarily numb ...
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 ...
