Evaluation of The Relationships Between Rhinosinusitis and Various Odontogenic Parameters using CBCT

Purpose: The diagnosis of rhinosinusitis relies on a combination of clinical symptoms and objective findings. This study primarily aimed to identify true rhinosinusitis patients using cone-beam computed tomography and to evaluate the relationships between rhinosinusitis and odontogenic parameters. A secondary objective was to assess mucosal thickening and its association with odontogenic factors. Material and Methods: The study included 378 patients who underwent cone-beam computed tomography scans for various indications. Rhinosinusitis diagnosis was based on “European Position Paper on Rhinosinusitis and Nasal Polyps” guidelines, incorporating clinical symptoms and radiological findings. Cone-beam computed tomography imaging parameters included periapical lesions, posterior tooth loss, root-sinus relationships, and oroantral communication. Mucosal thickening was classified as present (≥2 mm) or absent (
