| 520 | _aMeasurements of the maxillofacial region need detailed examination and precise evaluation during planning for surgical intervention to anticipate the functional, aesthetic, and psychosocial outcomes of the intended plan. Cone-beam computed tomography has been widely accepted in oral and maxillofacial applications due to its three dimensional property and isotropic nature so it can be accurately used in different dental and maxillofacial measurements. However, CBCT suffers from increased image noise and poor soft tissue contrast. The exposure parameters used in the CBCT scanning has a direct effect on the radiation dose delivered to the patient and quality of the resultant image. This study aimed to evaluate the accuracy of cone beam computed tomography in maxillary and mandibular angular measurements using varying electric potential difference (kVp) settings of the cone beam computed tomography machine | ||
