The Increase in Thickness of Maxillary Sinus Mucosa and Its Relationship with Odontogenic Factors in Panoramic Images of Patients

Introduction: Odontogenic infections are one of the common causes of maxillary sinusitis. The aim of this study was to evaluate the increase in maxillary sinus thickness and its relationship with odontogenic factors in panoramic images. Materials & Methods: This retrospective cross-sectional study examined 1246 sinuses. The images recorded odontogenic factors such as periapical lesions, dental caries, root canal treatment, periodontal lesions, and implants. Their relationship with the increase in the thickness of maxillary sinus mucosa was evaluated. The data was analyzed with SPSS16 statistical software and chi-square, as well as the significance level (P < 0.05). Results: Among the examined panoramic images, 468 showed an increase in the thickness of the sinus mucous membrane. There was a significant relationship between dental caries, periapical lesions, root canal treatment, and periodontal diseases with an increase in the thickness of the sinus mucosa (P = 0.001). There was no significant relationship between the presence of the implant and the increase in maxillary sinus mucosa thickness (P=0.057). Conclusion: The results of this study significantly correlate the increased thickness of the maxillary sinus mucosa with odontogenic and inflammatory lesions.
