Endodontic diagnosis is a crucial part of dental care that focuses on identifying conditions affecting the pulp of the tooth, which comprises the nerves and blood vessels. This diagnosis involves a thorough examination and evaluation of clinical symptoms, radiographic findings, and sometimes, additional tests to identify issues like dental caries, pulpitis, abscesses, or other pulp-related diseases. A correct endodontic diagnosis is essential to determine the most suitable treatment plan, whether it be root canal therapy, endodontic surgery, or other interventions, to relieve pain and preserve the natural tooth.
