ABSTRACT

Objective: To evaluate the effectiveness of panoramic radiography to establish the relationship of the upper third molars and the inferior cortical of the maxillary sinus, in comparison with the Cone Beam Computed Tomography (CBCT). Material and methods: The work included 72 patients, 34 upper left maxillary molars and 38 rights were studied. Measurements were made with the program to establish the distance between the lower cortex of the maxillary sinus and the apex of the upper third molar from the image of the panoramic radiograph in what was established as parameters: «at a distance, in contact and inside the floor of maxillary sinus». Then with the oblique or paraaxial slices of the computed tomography (CBCT) the true location in the bucco-palatal plane was observed. Results: Of the total upper third molars, 34 were left (47.22%) and 38 right (52.78%). In the panoramic X-ray 18 cases (25%) were found at distance to the maxillary sinus, 12 in contact (16.7%) and 42 inside (58.3%) of the maxillary sinus. The tomography showed 20 cases (27.8%) at a distance from the canal, 16 (22.2%) in contact and 36 (50%) inside the maxillary sinus. Statistically significant differences were observed (p ‹ 0.05) between the Rx. panoramic and tomography (CBCT) of the third molars that are inside the maxillary sinus. Conclusion: From the results obtained, we can establish that the panoramic radiograph does not allow knowing the true relationship between the inferior cortical of the maxillary sinus and the upper third molars.
