Endodontics encompasses the study and practice of the basic and clinical sciences of the biology of the normal dental pulp and and the etiology, diagnosis, prevention and treatment of diseases and injuries of the dental pulp along with associated periradicular conditions. Endodontics has evolved tremendously in the past decade and its applications have immensely improved the quality of dental treatment.
