Definition of Endodontics
 Endodontics is the branch of dentistry that is
 concerned with the morphology, physiology and
 pathology of the dental pulp and the periradicular
 tissues.

 Its study and practice encompass basic clinical
 sciences including the biology of the normal
 pulp, and the aetiology, diagnosis, prevention,
 and treatment of diseases and injuries of the pulp
 and the associated periradicular conditions.
What is an Endodontist ?
An Endodontist conducts that part of specialist
dental practice which deals with the diagnosis,
the surgical and adjunctive treatment of diseases,
injuries and defects of the dental pulp and
associated structures.


 Endodontic treatment must be conducted in the
    context of a concern for the patient's total
              oral and general health.
