Abstract

Objective: Thorough assessment of the Maxillary Sinus (MS) is very important. Panoramic Radiography (PR) is an accessible and well-established imaging technique in dental practice, however, inherited inaccuracies are always present. Recently, cone beam computed tomography (CBCT) is emerging as an acceptable alternative. Thus, the aim of this study is to compare the diagnostic accuracy of panoramic and CBCT images for the evaluation of opacifications in the MS.

Methods: Panoramic and CBCT images of 51 patients were selected from a data base. The images were randomly assessed by two calibrated evaluators in two reading sessions for the presence or absence of opacifications in the MS. A third oral radiologist evaluated the imaging findings provided by the CBCT and defined the gold standard.

Results: Of the 51 evaluated cases, 33 patients, 20 females and 13 males, presented opacifications in the MS. The results showed significant disagreement between the diagnosis of the two evaluators and gold standard (76,5% and 60,8%) and also fair agreement between the evaluators (68,7%).

Conclusions: CBCT images were more efficient to evaluate and locate opacifications involving the MS. Panoramic images were able to correctly identify but not to locate them.
