Prevalence of Odontogenic and Non-Odontogenic Cysts at Sari Bu Ali Sina Hospital: A 10-Year Retrospective Analysis
Abstract
Background and purpose: Periodic diagnosis and follow-up of odontogenic and non-odontogenic cysts are necessary to prevent malignancies and their consequences and can be of great benefit to health systems. The present study aims to assess the prevalence of odontogenic and non-odontogenic cysts in patients attending Sari Bu Ali Hospital. Materials and methods: We reviewed the pathology records (2011-2020) of patients in Sari Bu Ali Hospital and odontogenic and non-odontogenic cysts and also demographic data such as gender, age and location of the lesions. The relationships between the type of cysts and sex, age, and location of the lesions were determined by using Chi-square and Fisher's exact test in SPSS V22. Results: Findings showed 115 cysts; 81 (70.4%) in men and 34 (29.9%) in women. Patients aged 30-44 years old (27.8%) attended the hospital more than other age groups. Odontogenic cysts and non-odontogenic cysts were seen in 97.4% and 2.6% of the cases. Non-odontogenic cysts were seen only in women, while odontogenic cysts were common in both men and women (100% and 91.2%, respectively). The sites with the highest prevalence of cysts in men and women were the mandible and maxilla, respectively. Conclusion: According to the present study, the frequency of odontogenic cysts was higher than non-odontogenic cysts. Compared with other studies, the prevalence of non-odontogenic cysts was lower in this study and odontogenic cysts were mainly of inflammatory origin.
