Abstract Introduction: Diagnosis of sinus retention cysts indicates inflammatory reaction in sinuses and in attention to its reports in different geographic sites we decided to survey its frequency in panoramic radiography. Because it doesn’t have the limitation of waters’ view in detection of small lesion in antral floor due to superimposition of molar roots and petrous bone in this area and it can be used as a routine radiography in dentistry. Objective: This study was designed to determine the frequency of retention cyst in panoramic view in Rasht-Iran from the beginning of winter of 2003 to 2004. Materials and Methods: Two maxillofacial radiologists assessed 1422 panoramic radiographs, which were taken by Planmeca EC Proline machine together during one year. Absence or presence of this lesion, number of these cysts and location of antral wall involvement were defined. Data collections were organized on sex, age and months of radiography taking. SPSS analysis software, chi-square test and t-test were used for statistical analysis. Results: Frequency of retention cyst was 4% and it was more in males than females. Ninety percent of this antral lesion was single and 10% had multiple forms. The most common location involved was antral floor. June and January were the most common months of retention cyst presentation in Rasht in panoramic views. Conclusion: In our study, frequency of antral cyst was higher than previous studies. Temperature fluctuations, inflammatory and allergic factors in different months are effective factors in higher presentation of retention cyst in this geographic region. Antral floor involvement in single form and retention cyst presentation in male more than female are the most important notes of this study.
