Cone beam computed tomography in endodontics

Abstract

Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillo-facial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.

“…VKK vakalarında görülen J ve hale şeklindeki radyolüsent alanlar kemikte lezyonun görünmesi içi gerekli miktarda yıkım gerçekleşmeden tespit edilemeyebilir. Ayrıca apikal periodontitisli vakalarda benzer şekillerde görülen radyolüsent alanlar VKK ile karıştırılabilir 21 . Travma sonucunda meydana gelen kök kırıklarının tespit edilememesi bu dişlerin uygun olmayan bir şekilde tedavi edilmesi ile sonuçlanacaktır.…”

Evaluación de Lesiones Periapicales en Pacientes Derivados a Cirugía Periapical Mediante Tomografía Computarizada de Haz Cónico

“…Por lo cual, existen diferentes factores que reducen la capacidad diagnóstica de la radiografía periapical (Scarfe et al, 2009). La Tomografía Computarizada de Haz Cónico (CBCT) es un sistema de diagnóstico imagenológico, contem-poráneo, de visualización tridimensional, diseñado especialmente para su uso en el esqueleto maxilofacial, siendo significativamente más sensible que la radiografía convencional a la detección de periodontitis apicales en humanos (Durack & Patel, 2012). Con su uso se pueden detectar lesiones adicionales, reportándose que en un 70 % de los casos entrega información clínicamente relevante, que no se encontraba con el uso de radiografía periapical (Lofthag-Hansen et al).…”

A Cone Beam Computed Tomography Study Among Dental Residents Based on a Questionnaire

“…CT technique uses X-rays in a different way than CBCT and it needs more sequence images for the 3D rebuild which has a lower quality then CBCT's 3D reconstruction. CBCT system performs only a single rotation sequence which is sufficient in collecting data for reconstructing the final 3D image compared to 2D images like retro alveolar x-rays that needs a separate scan every time (Patel S 2012, Durack C et al 2012.…”
