Atraumatic restorative treatment (ART) [1] is a method for cleaning out tooth decay (dental caries) from teeth using only hand instruments (dental hatchet and spoon-excavator) and placing a filling. It does not use rotary dental instruments ( dental drills ) to prepare the tooth and can be performed in settings with no access to dental equipment.
Wisdom teeth have been described in the ancient texts of Plato and Hippocrates, the works of Charles Darwin and in the earliest manuals of operative dentistry. It was the meeting of sterile technique, radiology, and anesthesia in the late 19th and early 20th centuries that allowed the more routine management of impacted wisdom teeth.
For example, sterile equipment and fluids are used during invasive medical and nursing procedures. [11] The largest manifestation of such aseptic techniques is in hospital operating theaters, where the aim is to keep patients free from hospital micro-organisms.

Dental equipment in an autoclave to be sterilized for 2 hours at 150 to 180 degrees Celsius. A medical autoclave is a device that uses steam to sterilize equipment and other objects. This means that all bacteria, viruses, fungi, and spores are inactivated. [13]
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

An x-ray of a root canal operation. Before endodontic therapy is carried out, a correct diagnosis of the dental pulp and the surrounding periapical tissues is required. This allows the endodontist to choose the most appropriate treatment option, allowing preservation and longevity of the tooth and surrounding tissues.
The dental dam is prepared by punching one or more holes in the dental dam sheet to enable isolation of the appropriate number of teeth required for the dental procedure. The dental dam is then applied to the tooth, anchored into place using a metal or flexible plastic clamp (chosen according to the tooth and area it will be applied to).
The SDSCS classifies sterilization techniques into three categories: critical, semi-critical, and non-critical. [3] For critical situations, or situations involving contact with sterile tissue or the vascular system, sterilize devices with sterilants that destroy all bacteria, rinse with sterile water, and use chemical germicides.
