In vitro evaluation of periodontal defects with intraoral radiography and cone beam computed tomography

A statistically significant difference was found between CBCT and IOR in terms of the detection of dehiscence, one of the periodontal defects, and CBCT was concluded to be more successful than IOR in the diagnosis of dehiscence defects. No statistically significant difference was found between IOR and CBCT in detecting fenestration and Class III furcation type defects. CBCT was found to be more successful than IOR in detecting defects in the anterior region. However, no difference was found between the two methods in the posterior region.
