Root-canal therapy: a means of treating oral pain and infection

Can Fam Physician. 1988 Jun:34:1357-65.

Abstract

What is root-canal treatment? This article shows how endodontic treatment (root-canal therapy) can preserve teeth that would otherwise be extracted, and how tooth-pulp pathology can be diagnosed. Some clinical examples illustrate how non-dental infections can masquerade as dental problems, and vice versa.
