ABSTRACT
Statement of the Problem: Mucous retention cysts [MRCs] of the maxillary sinus are lesions with undefined pathogenesis. In recent researches, geographical and climatic aspects have been related as risk factors
Purpose: The purpose of this study was to determine the frequency of MRCs of the maxillary sinus using panoramic radiographs
Materials and Method: A total of 631 panoramic radiographs were selected from a secondary database from a private radiology clinic and analyzed by two specialists in dental radiology according to gender, age, month, relative air humidity, and mean temperature
Results: A total of 87 [6.89%] radiographic images were suggestive of MRCs. Thirty-five MRCs [40.22%] were detected on the right side, 10 [11.49%] on the left side and 42 [48.29%] on both sides. A high frequency was detected in female participants [n=45; 51, 72%], those aged 18-35 years [n=31; 35, 63%] and those from August [n=24; 27.59%] and July [n=22; 25.29%]
Conclusion: The frequency of MRCs was low, and no statistically significant correlation was found between the prevalence of MRCs and the studied variables with the exception of the mean temperature
