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.

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.

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.

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.

Nasopalatine duct cysts are the most common of developmental non-odontogenic cysts in the oral cavity and represent 10% of maxillary cysts. The cyst arises from epithelial remnants from the nasopalatine duct. These cysts are usually asymptomatic, but the most commonly reported clinical symptom is swelling in the anterior part of the palate, just behind the palatal papilla. This swelling is not always on midline. The recurrence of this is rare (2%). In this report, a 21-year-old man from Ahvaz, with the chief complaints of numbness, anterior teeth mobility, intraoral swelling and facial asymmetry, is reported. On clinical examination, a nontender swelling on the midline of hard palate and buccal vestibule, covered by normal mucosa was seen. The crown of central incisors was displaced mesially. In panoramic, maxillary occlusal cross sectional, anterior maxillary periapical and computed tomography views, a well-defined unilocular radiolucency with corticated margins was seen in the anterior region of maxilla. Biopsy of the lesion was planned and final pathologic diagnosis was “nasopalatine duct cyst”. Therefore, nasopalatine duct cyst is one of the differential diagnoses of unilocular radiolucencies in the anterior region of maxilla. Histopathologic examinations help us to reach the correct diagnosis and disburden us from unnecessary treatments.
