Endodontics

From Wikipedia, the free encyclopedia

If decay progresses to the first stage, a small filling will be required. If decay develops to the third stage depicted, root canal therapy will be required.

Endodontics, from the Greek endo (inside) and odons (tooth), is one of the nine specialties of dentistry recognized by the American Dental Association, and deals with the tooth pulp and the tissues surrounding the root of a tooth. If the pulp (containing nerves, arterioles and venules as well as lymphatic tissue and fibrous tissue) has become diseased or injured, endodontic treatment is required to save the tooth.
