Objective: This study aimed to evaluate the relationship between maxillary posterior teeth and maxillary sinus mucosal thickening using cone beam computed tomography (CBCT).

Methods: This retrospective study included CBCT images of healthy individuals aged 18-60 years. Premolar and molar teeth were examined due to their proximity to the maxillary sinus. The relationship between the teeth and the maxillary sinus was classified as “no contact, in contact, or inside the root sinus”. The presence of apical lesions was classified as "absent or present." Additionally, tooth absence was recorded. Maxillary sinus mucosal thickening was measured separately for each tooth region. Mann-Whitney U test and Kruskal-Wallis test were used for statistical analysis. A significance level of p <0.05 was determined.

Results: A significant relationship was found between tooth-sinus relationship and mucosal thickening. Mucosal thickening was higher when the tooth root was in contact with the sinus floor or within the sinus. A significant relationship was found between apical lesions and mucosal thickening. Mucosal thickening was higher in the presence of an apical lesion.

Conclusion: Clinicians should pay attention to interactions between dental factors and the maxillary sinus. Further studies examining additional parameters are needed in the future.
