Abstract

With our study we wanted to compare the diagnostic accuracy of conventional radiography (orthopanoramic and intraoral radiography) and Cone Beam CT (CBCT) for the diagnosis of periapical lesions on the posterior elements of the upper maxilla endodontically treated. The images were analyzed by a radiologist and an endodontist whose interpretation of radiological examinations is unique. Were examined 34 molars (23 first molars and 13 second molars) with a total of 102 roots. The CBCT detected a significantly higher number of lesions (43%, p <0.001) compared to conventional radiography. Our results demonstrate that the CBCT can be inserted into the diagnostic routine for the evaluation of all pre-prosthetic posterior elements of the upper jaw endodontically treated in addition to the diagnostic techniques 2D, especially when in the treatment plan is provided the realization of an abutment. The CBCT, which has reduction of cost and absorption of radiation with respect to the conventional CT, is also very useful even when there is a need to perform a surgical treatment-endodontic (apicectomy) of a lesion diagnosed with 2D techniques.
