Abstract

Endodontic emergency is defined as the condition associated with pain and/or swelling which requires immediate diagnosis and treatment. The emergencies are matter of great concern to the both patient and dentists. Emergencies can occur with varying frequencies of pain and swelling in patients before, during and after the root canal treatment. These emergencies are result of combination of various factors which induce severe inflammation in pulp and periapical tissues. The irritation of periradicular tissues result in inflammation and the release of various chemical mediators which initiate inflammation. The pain in endodontic emergencies is mainly related to two factors, chemical mediators and pressure. chemical mediators cause pain directly by lowering the pain threshold of sensory nerve fibers or by increasing vascular permeability and producing edema. Increased fluid pressure resulting from edema directly stimulates the pain receptors.
