Effect of different exposure setting on the diagnosis of vertical root fractures on cone-beam computed topography images

By considering the importance of vertical root fractures (VRF) and the known complications of incorrect diagnoses, the present study aimed to evaluate the effect of different kilovoltage peak (kVp) and milliampere (mA) settings in cone-beam computed tomography (CBCT) on the diagnosis of VRFs in endodontically treated single-canal premolars. Eighty intact human premolars were endodontically treated and coded. The roots of half of the samples were fractured, and CBCT images were taken by using four different combinations of maximum (max) and minimum (min) kVp (60-86) and mA (6-10) settings under the same conditions. The images were randomly observedtwiceby an experienced oral and maxillofacial radiologistover a two-week interval. The results were analyzed by Chi-square test. . In the kVp max/mA max group, none of the images were diagnostic. In the kVp max/mA min group, 62 images (77.5%) were nondiagnostic. The results of these two groups showed significant statistical differences with the other two groups (P
