Background: The diagnosis of odontogenic sinusitis is important because the pathology, microbiology and the treatment of the odontogenic sinusitis are different from the other forms of the sinusitis. In this study, the relationship between dental pathologies and maxillary sinus diseases were examined comprehensively. Methods: In this study, the ۵۰۰ images taken by dental volumetric tomography were examined retrospectively. The vertical distances between the maxillary sinus floor and the teeth apexes were examined. The dental pathologies and the maxillary sinus diseases were reported. Chi-square and Fisher’s exact tests were used for analysis. Results: Focal mucosal thickening was the most common sinus pathology (۶۰.۲%). A relationship was found between the mucosal thickening of apical lesions, remained roots and healthy implants (p <۰.۰۵). Mucus retention cysts were associated with apical lesions and periodontal defects (p <۰.۰۵). Polyp was found to be related with the deep caries, healthy implants, horizontal bone loss and fixed orthodontic treatment (p<۰.۰۵). Periostitis was found to be associated with apical lesions and periodontal defects. A relationship was detected between sinusitis with root fragments and apical lesions (p<۰.۰۵). Conclusion: Odontogenic infections and odontogenic sources may play a role in the formation of maxillary sinus pathologies. Dental volumetric tomography is very useful in showing the relationship between maxillary sinus with maxillary teeth and the diagnosis of odontogenic sinus pathologies.
