ABSTRACT Background The evolution of cone beam computed tomo- graphy three-dimensional (CBCT 3D) imaging has dramatically changed the potential for presurgical and pretreatment planning, such that outcomes are more predictable and complications more avoidable. Purpose The purpose of this article was to systematically review scientific and clinical literature pertaining to the uses and benefits of 3D imaging CBCT for diagnosis and treatment planning in Implantology including prosthodontics. Materials and methods Various databases, like PubMed, EBSCOhost and ScienceDirect, were searched from 1998 to 2010 to retrieve articles regarding the clinical applications of CBCT in dentistry. Cone beam computed tomography in dentistry was used as a key phrase to extract relevant articles in dentistry. A manual search for the references from the retrieved articles was also completed. The articles published only in English, randomized clinical trials, prospective and retrospective clinical studies, laboratory and computer-generated research were included.   The search revealed 540 articles of which 447 were irrele- vant to the study and therefore excluded. Results Cone beam computed tomography has created an opportunity for clinicians to acquire the highest quality diagno- stic images with an absorbed dose that is comparable to other dental radiological examinations and less than a conventional CT. Therefore, if placement of an implant might approach a nerve, invade the sinus, or penetrate out of the confines of the jawbone, the patient should be offered a discussion of CBCT 3D imaging. In addition, CBCT 3D patients should be advised of the risks, benefits and alternatives to such treatment, based upon any additional data provided by the imaging.

Abstract Background Endodontic disease can adversely affect the quality of life and therefore early diagnosis and consequent timely treatment is of paramount importance for the Endodontist. Radiology is an essential component in treatment planning, disease monitoring and assessment of treatment outcome. Periapical radiographs and panoramic radiography are frequently utilised but they provide only two-dimensional representation of three-dimensional structures. The advent of cone beam computed tomography (CBCT) offers three-dimensional accuracy of the hard tissue images with a reasonable cost and this has revolutionised imaging of the dentomaxillofacial structures. This imaging system has been seen to overcome some limitations of conventional radiography, as brought out in this review. The improvement in the accuracy is, however, accompanied at the cost of increased radiation exposure to the patient. Nevertheless, smaller areas of exposure are normally appropriate for endodontic imaging, and adjustment in the exposure parameters can further moderate the effective dose (Loubele et al. 37(6):309-18, 2008). Aims and objectives The aim of this review is to present the pertinent literature on the various applications of cone beam computed tomography in the field of endodontics. Methods Literature was electronically searched on the following sources; Medline and Keats Library. Further, a manual search was performed on the following journals: International Endodontic Journal, Journal of Endodontics, Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, Endodontology, Journal of Dental Research, European Journal of Oral Sciences & Odontology and Dentomaxillofacial Radiology. A preliminary search was performed to gain an idea of the available literature using keywords ‘Cone Beam Computed Tomography’ to view the volume of the literature evident and identify questions to be addressed in this review. The initial search showed 243 potential articles. After scrutinising the titles and abstracts of the retrieved articles, 70 relevant studies were reviewed in full text. Furthermore, ‘published guidelines on the use of CBCT’ were also searched so as to include the results as an additional source material. All the articles eligible to be included in the review were in the English language and ranged from the year 1960 to the present. Also all the studies reviewed were based on the various uses of cone beam computed tomography in the field of endodontics. The keywords used to search were ‘Cone Beam Computed Tomography (CBCT)’, ‘Conventional radiography’, ‘Applications of CBCT in endodontics’, ‘CBCT and tooth morphology’, ‘CBCT and apical periodontitis’, ‘CBCT and vertical root fractures’, ‘CBCT and resorption’, ‘CBCT and pre-surgical assessment’, ‘CBCT and dento-alveolar trauma’ and ‘CBCT and endodontic outcome’. Results Every case is unique and CBCT should be considered only after studying each case individually. CBCT imaging needs to be adopted or used where information from conventional imaging systems is either inadequate for the management of endodontic problems or inconclusive. Having said that, it is safe to state that CBCT imaging has the potential to become the first choice for endodontic treatment planning and outcome assessment, especially when new scanners with lower radiation doses and enhanced resolution would be available.

Dental cone beam computed tomography (CBCT) is the three-dimensional imaging of choice in modern dentistry. In the developed world, guidelines have been published on the use of CBCT in dentistry, largely in response to the risks associated with ionising radiation exposure. However, the availability of different models on the market at affordable prices has made this machine an integral part of the contemporary dentists’ apparatus, even in the developing world. Here, we underline the importance of awareness on radiation protection, image acquisition, familiarity with the software and image interpretation.

Radiographic Interpretation

Radiographic interpretation and diagnosis of dental impactions have always posed a great challenge to the orthodontist to manage such case. This could largely be attributed to the limitations posed by the conventional two-dimensional (2D) imaging modalities. Dental impactions, which can position into various underlying locations, can be evaluated accurately using cone beam computed tomography (CBCT) three-dimensional (3D) imaging, rather than conventional 2D radio-imaging. This article report a case of orthodontic management of impacted canine of a 13 years old boy where conventional 2D radio-imaging diagnosis are modified by cone beam computed tomography (CBCT).

The study sought to assess whether the soft tissue facial profile measurements of direct Cone Beam Computed Tomography (CBCT) and wrapped CBCT images of non-standardized facial photographs are accurate compared to the standardized digital photographs. In this cross-sectional study, 60 patients with an age range of 18–30 years, who were indicated for CBCT, were enrolled. Two facial photographs were taken per patient: standardized and random (non-standardized). The non-standardized ones were wrapped with the CBCT images. The most used soft tissue facial profile landmarks/parameters (linear and angular) were measured on direct soft tissue three-dimensional (3D) images and on the photographs wrapped over the 3D-CBCT images, and then compared to the standardized photographs. The reliability analysis was performed using concordance correlation coefficients (CCC) and depicted graphically using Bland–Altman plots. Most of the linear and angular measurements showed high reliability (0.91 to 0.998). Nevertheless, four soft tissue measurements were unreliable; namely, posterior gonial angle (0.085 and 0.11 for wrapped and direct CBCT soft tissue, respectively), mandibular plane angle (0.006 and 0.0016 for wrapped and direct CBCT soft tissue, respectively), posterior facial height (0.63 and 0.62 for wrapped and direct CBCT soft tissue, respectively) and total soft tissue facial convexity (0.52 for both wrapped and direct CBCT soft tissue, respectively). The soft tissue facial profile measurements from either the direct 3D-CBCT images or the wrapped CBCT images of non-standardized frontal photographs were accurate, and can be used to analyze most of the soft tissue facial profile measurements.
