Cone-beam computed tomography (CBCT) is a relatively new modality providing 3D imaging that has become more accessible than ever to dental practice. This brings in new challenges that need to be addressed. This article discusses the role of CBCT in dentistry and highlights the availability of current guidelines.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

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.
