(dentistry) The branch of dentistry concerned with the study, treatment, and prevention of the diseases of dental pulp and periapical tissues


Endodontics is a branch of dentistry that deals with dental pulp and root. It is concerned with the morphology, physiology, and treatment of dental pulp and periapical tissues. Thus, it includes the biology of the normal dental pulp (containing nerves, arterioles, venules, fibrous tissues, and lymphatic tissues) as well as the etiology, diagnosis, treatment, and prevention of diseases and injuries of the pulp and the associated tissues. It was recognized as a specialty in dentistry in the early period of the twentieth century. Before that period, the discipline is referred to as root canal therapy.1 At present, endodontics treatments and procedures do not only involve root canal therapy but also other dental treatments such as endodontic retreatment, cracked teeth treatment, and dental trauma treatment. Root canal therapy though is a common procedure in this field and is recommended in saving the tooth by treating the dental pulp that becomes diseased or injured.

Word origin: Greek endo- (inside) + Greek odṓn (toothed) + -ics (study, field of knowledge)
