Abstract

Dental radiography is an essential tool in endodontics for determination of diagnosis, treatment planning and monitoring of treatment outcome. Conventional two-dimensional imaging remains the most commonly used and the standard method of radiographic imaging in endodontics due to accessibility and low radiation exposure. The use of cone beam computed tomography is increasing worldwide due to the benefits of three-dimensional visualisation of the teeth under investigation and surrounding structures. Its use, however, should be considered on a case-by-case basis, taking into consideration the benefits and increased dose of radiation in line with published guidelines.

Key points

  • Dental imaging is a fundamental tool in endodontics, used for diagnosis, treatment planning and review of endodontic outcomes.
  • Intra-oral periapical radiographs remain the most common imaging modality used in endodontics and should be used in conjunction with electronic apex locators.
  • Low-volume cone beam computed tomography (CBCT) provides 3D information on root morphology and surrounding structures. Due to the higher radiation dosage relative to conventional dental imaging techniques, CBCT is normally used for the more complex endodontic cases.
