Abstract
Background: The relation of maxillary posterior teeth roots to the maxillary sinus floor is important for diagnosing and planning of many surgical procedures. The anatomical proximity of the root apices of the maxillary posterior teeth to the maxillary sinus floor may favor the development of inflammatory, infectious and/or traumatic alterations in the maxillary sinus. Objective: To correlate the topographic relationship of the maxillary sinus floor to the posterior teeth roots using panoramic radiography and cone beam computed tomography (CBCT). Methods: Panoramic and CBCT images of 30 patients were analyzed. The relationship between the posterior teeth and the maxillary sinus and panoramic radiography signs associated with protrusion of root apices into the sinus were evaluated following Kwak et al. (2004) classification. Results: The OPG showed statistically significant (P>0.001) longer root projection in the sinus cavity in comparison with the root protrusion into the sinus measured by using CBCT images. It was found that cbct was statistically more significant than OPG. Given the limitations of panoramic radiography being a 2D radiography. Conclusion: CBCT is reliable in assessment of topographic relationship of maxillary sinus floor with the posterior teeth in comparision with panoramic radiography CBCT is indicated to provide the information about the relation to the maxillary sinus floor when there is protrusion detected in panoramic images.
