Debridement
From Wikipedia, the free encyclopedia
Debridement is a medical term referring to the removal of dead, damaged, or infected tissue to improve the healing potential of the remaining healthy tissue. Often this removal is surgical, but other methods exist: mechanical, chemical, autolytic (self-digestion), and even maggot therapy, where certain species of live maggots selectively eat only necrotic tissue. This treatment is usually done in gangrene cases and other serious bacterial infections, as well as frostbite.
In oral hygiene, debridement refers to the removal of the dental tartar that has accumulated over teeth. Debridement in this case is done using hand tools and ultrasound instruments. The ultrasound dislodges the tartar, which is then removed.
