Computed tomographic imaging in endodontics: a short literature review

This paper reviews the literature concerning computed tomography and other modalities such as spiral computed tomography, micro-computed tomography, cone-beam computed tomography, tuned-aperture computed tomography and optical coherence tomography in endodontics. Among the plethora of imaging modalities currently available, these recent imaging systems tend to draw attention from the clinicians. But still there is a lack of evidence-based data on the radiation dose and patient selection criteria for these imaging modalities, which calls for a set of guidelines to be introduced for their use in clinical practice in the future. Keywords: coherence tomography, computed tomography, cone-beam computed tomography, microcomputed tomography, optical tuned-aperture computed tomography, spiral computed tomography
