1 Endodontics

The word endodontic comes from two Greek words meaning “inside” and “tooth.” Endodontics is the science of diagnosing and treating pulpal and periradicular disease. Endodontics is that branch of dentistry concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. Its study and practice encompass the basic and clinical sciences, including the biology of the normal pulp, and the etiology, diagnosis, prevention, and treatment of diseases and injuries of the pulp and associated periradicular conditions.*

This review outline is similar to the outline of the textbook Principles and Practice of Endodontics, ed 3 (Elsevier, St. Louis, 2002); Problem Solving in Endodontics, ed 4 (Elsevier, St. Louis, 2005); and Pathways of the Pulp, ed 9 (Elsevier, St. Louis, 2006). Some contents in this review have been taken from these texts. This review is not meant to be a comprehensive review of endodontics but, rather, a guide to study in preparing for the endodontic section of Part II of the National Board Dental Examination (NBDE). Students are referred to other sources, including the above texts, for more complete discussion in each area of endodontics. This review will help organize and integrate knowledge of concepts and facts. It will also help students to identify those areas requiring more concentrated study.


1.1 Pulpal Diseases

B. Physiology of pulpal pain

C. Clinical classification of pulpal diseases

3. Irreversible pulpitis

4. Necrosis

1.2 Periradicular Diseases

B. Classification of periradicular diseases

2. Acute periradicular abscess (acute apical abscess)

1.3 Endodontic Diagnosis

C. Dental history

1.4 Endodontic Examination and Testing

Intraoral Endodontic Examination

Intraoral diagnostic tests enable the practitioner to:

C. Thermal tests (Table 1-1)

Thermal tests are especially valuable when the patient describes the pain as diffuse. Thermal testing of vital pulps often helps to pinpoint the source. However, the sensory response of the teeth is refractory to repeated thermal stimulation. To avoid misinterpretation of a response, the dentist should wait an appropriate time for tested teeth to respond and recover.

D. Electric pulp tests (see Table 1-1)

I. Radiographic exam

4. Radiographic differential diagnosis of periradicular radiolucencies (Table 1-2)

1.5 Cracked Tooth Syndrome

1.7 Endodontic–Periodontal Relationships

B. Types of endodontic and/or periodontal lesions
