  • Finish an approved endodontic program
  • Have a valid dental license
  • Show at least two years of endodontic work experience

Exam Structure and Format

The ABE Test has two parts: a written test and a clinical test. The written test checks your endodontic skills proficiency and root canal procedure qualification. It covers topics like diagnosis, treatment planning, and managing patients. The clinical test looks at your endodontic mastery by seeing you do endodontic procedures.

Sample American Board of Endodontics Practice Questions

Try these questions from our free American Board of Endodontics practice tests. The correct answer and an explanation follow each question.

  1. A dentist anesthetizes tooth #30 with an IANB and the patient still reports cold sensitivity. The tooth has a positive cold response and no periapical pathology. What test should be performed next?

    • A. Selective anesthesia of adjacent teeth to localize the source
    • B. Repeat IANB injection at higher dose
    • C. Begin endodontic treatment on tooth #30
    • D. Order CBCT imaging immediately

Answer: A. Selective anesthesia of adjacent teeth to localize the source

When the symptomatic tooth cannot be identified after anesthesia, selective anesthesia of adjacent teeth helps localize the true source of pain.

  • What is the primary use of Cone Beam Computed Tomography (CBCT) in endodontics?

    • A. To assess the cosmetic appearance of the tooth
    • B. To provide detailed three-dimensional imaging of the tooth and surrounding structures
    • C. To measure the tooth's sensitivity
    • D. To track the tooth's eruption pattern
  • Answer: B. To provide detailed three-dimensional imaging of the tooth and surrounding structures

    Cone Beam Computed Tomography (CBCT) is an advanced imaging technique that provides high-resolution, three-dimensional views of dental and maxillofacial structures. In endodontics, this detailed 3D visualization is invaluable for accurately assessing complex root canal anatomy, identifying subtle periapical lesions, and planning intricate treatments. Unlike traditional 2D radiographs, CBCT eliminates the problem of superimposition, offering a comprehensive understanding of the tooth's internal and surrounding structures.

  • What is a common challenge when interpreting periapical radiographs in endodontics?

    • A. Difficulty in visualizing the tooth's surface texture
    • B. Overlapping of anatomical structures, which can obscure root canal anatomy
    • C. Lack of color differentiation in radiographs
    • D. Excessive radiation exposure to patients
  • Answer: B. Overlapping of anatomical structures, which can obscure root canal anatomy

    A common challenge with periapical radiographs in endodontics is the overlapping of anatomical structures. Since these are two-dimensional images of three-dimensional objects, features like the zygomatic arch, cortical bone, or adjacent roots can be superimposed, obscuring the intricate root canal anatomy, accessory canals, or subtle periapical pathology. This superimposition can make it difficult to obtain a clear and complete diagnostic picture, often requiring multiple angulations or 3D imaging for a comprehensive assessment.

  • Triple antibiotic paste (TAP) used in regenerative endodontics is classically composed of which three antibiotics?

    • A. Metronidazole, ciprofloxacin, and minocycline
    • B. Amoxicillin, metronidazole, and tetracycline
    • C. Clindamycin, ciprofloxacin, and doxycycline
    • D. Penicillin, metronidazole, and erythromycin
  • Answer: A. Metronidazole, ciprofloxacin, and minocycline

    The classic TAP formulation consists of metronidazole, ciprofloxacin, and minocycline, first described by Hoshino et al. to disinfect infected root canals.
