The Evaluation of Relationship BetweenMaxillary Sinus Diseases and DentalPathologies Using Dental VolumetricTomography

The diagnosis of odontogenic sinusitis is important because the pathology, microbiology and the treatment of the odontogenic sinusitis are different from other forms of the sinusitis. In this study, the relationship between dental pathologies and maxillary sinus diseases was examined comprehensively. In this study, 500 dental volumetric tomography (DVT) images were examined retrospectively. The vertical distances between the maxillary sinus floor and the teeth apexes were examined. The dental pathologies and maxillary sinus diseases were reported. Chi-squared and Fisher exact tests were used for data analysis. Focal mucosal thickening (FMT) was the most common sinus pathology (60.2%). A relationship was found between the mucosal thickening of apical lesions, remaining roots and healthy implants (P < 0.05). Mucus retention cysts (MRCs) were associated with apical lesions and periodontal defects (P < 0.05). Polyp was related to the deep caries, healthy implants, horizontal bone loss and fixed orthodontic treatment (P < 0.05). Periostitis was associated with apical lesions and periodontal defects. A relationship was detected between sinusitis with root fragments and apical lesions (P < 0.05). Odontogenic infections and odontogenic sources may play role in the formation of maxillary sinus pathologies. DVT is very useful in showing the relationship between maxillary sinus and maxillary teeth and the diagnosis of odontogenic sinus pathologies.
