fa Frequency of Maxillary Sinus Mucous Retention Cysts in a Central Brazilian Population بیماری های دهان Oral Medicine پژوهشي Research <b> Statement of the Problem:</b> 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. <div>  <b>Purpose</b>: The purpose of this study was to determine the frequency of MRCs of the maxillary sinus using panoramic radiographs.</div><div><b> Materials and Method:</b> 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.</div><div><b> Results:</b> 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%). </div><div>  <b>Conclusion</b>: 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</div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dentistry Shiraz University of Medical Sciences </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://dentjods.sums.ac.ir/index.php/JDSUMS/article/view/827" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-3135&slc_lang=fa&sid=1 Evanice Menezes Marçal Vieira evanicemmvieira@gmail.com 100319475328460014481 100319475328460014481 Yes Dept. of Oral Diagnosis, School of Dentistry, University of Cuiabá, Cuiabá, Mato Grosso, Brazil.
