CBCT – Cone Beam Computed Tomography

Abstract

Dental X- Rays are important for diagnosing and treating patients by helping to detect oral health issues when they can’t be detected by visual or physical examination alone. Dental X-Ray take a much closer look and provide valuable information in the area of interest. Though 2 Dimensional X-Ray and Panoramic radiography can predict diagnosis in number of clinical cases, certain situations demand multiplanar imaging, one such technology is CBCT. CBCT is a specialised 3Dimensional Craniofacial imaging in which 3 Dimensional reconstruction is possible. The final reconstructed image produced, reveals multilayer images in 3 orthogonal planes (coronal, sagittal and transverse) This article focuses on CBCT and its applications in various fields of dentistry.

Cone Beam Computed Tomography (Cbct) and Endodontic Microscopic Assessment of C-Shaped Canal Systems in Mandibular Second Molars

“…The root canal framework is the standard form being used to estimate root canal framework, for which the root canal network is stained and cleared (Kumar and Khambete, 2013;Kailash, . The entrance to the canal normally is shown as a C-formed aperture (arch 180 o ) in the con iguration of a band and also as a shallow semi-mounted ridge linking the canals including distal, mesio-buccal and mesio-lingual.…”

“…This may also be a C-shaped canal with both the association of proximal and mesio-lingual channels as well as a distinct mesiobuccal tube. This is essential to stress the fact that somehow this C-shaped modi ications in the morphology will take place over the entire stretch of the racinum, which exacerbates the phases of the bio-mechanical procedures and shut-off of the teeth for this form of internal morphology (Kailash, 2014;Solomonov et al, 2012;Wang et al, 2012). Endodontics was not an independent technology with the utilization of ampli ication.…”

Asymmetric mandible identification using Cone Beam Computed Tomography (CBCT)

“…It may not always be clinically important because it illustrates the inconsistency of normal growth in mandible bone. [3][4][5][6] CBCT provides ideal image of the anatomical structures of high contrast and is especially useful for evaluating bone. For this reason, CBCT is rapidly replacing conventional CT and conventional radiography in clinical orthodontic practice.…”

Clinical application of Cone Beam Computed Tomography for evaluation of peri-implant bone thickness and temporo-mandibular joint imaging

“…The first attempts to capture image of the whole jaw were taken with intraoral radiation sources at the beginning of the 20th century. Panoramic radiography was first introduced in 1948 and almost 50 years later, in 1995 the first digital sensor for panoramic unit was applied [37].…”

“…The first CT scanner was released by a medical equipment manufacturer in 1974, and 2 years later, in 1976 the whole body CT scanner has become available [37,39].…”
