The Use of Cone Beam Computer Tomography (CBCT) in Endodontics

AbstractPurpose of ReviewCone beam computed tomography scans have been gaining popularity as a diagnostic aid. The purpose of this review is to understand the benefits and the limitations of this technology and its application in day to day clinical assessment. Familiarity with some basic principles of the technical aspect will aid the practitioner in controlling quality of the scan and the amount of radiation the patient is subjected to.Recent FindingsSignificant findings of this review are that the exposure to ionizing radiation is the main limiting factor in taking CBCT scans. The information obtained can be invaluable in treatment planning by providing a three-dimensional view of teeth and neighboring structures. The sensitivity of a scan to identify low radiodensity areas is significantly higher than two-dimensional X-rays; however, the histological nature of the affected bone is still being investigated.SummaryIn summary, while the clinician should weigh the risk and benefit before obtaining a scan, the industry should evaluate technology to reduce the exposure to radiation per scan further.
