Background and Objective: Odontogenic cysts and tumors are common and complex lesions of the jaw that are occasionally associated with impacted teeth and possess the potential to cause serious complications. The present study was conducted with the aim of investigating the frequency of odontogenic cysts and tumors and their association with impacted teeth over an 11-year period.
Methods: In this cross-sectional study, all medical records of the Department of Oral and Maxillofacial Pathology of Babol Dental School from 2012 to 2022 were reviewed. Patients' demographic characteristics, lesion location, involved impacted tooth, clinical and radiographic features of the lesion, clinical and radiological differential diagnosis, histopathological diagnosis, type of biopsy, and macroscopic characteristics of the lesions were extracted from the records and evaluated.
Findings: Of the 1512 samples examined, 428 cases (28.3%) were diagnosed as odontogenic lesions (85% odontogenic cysts and 15% odontogenic tumors). The majority of patients (54.4%) were male. The mean age of patients with cysts was 33.02±15.31 years, and that of patients with tumors was 32.53±16.08 years (p=0.819). Most lesions (27.1%) were observed in the third decade of life, and the majority of lesions (92.3%) exhibited a radiolucent appearance. Seventy-five percent of odontogenic tumors and 61.8% of odontogenic cysts were found in the mandible (p=0.043). The most common odontogenic cysts were radicular cyst, dentigerous cyst, and odontogenic keratocyst, and the most common odontogenic tumors were ameloblastoma and complex odontoma. The most common lesion in the age group under 20 years was dentigerous cyst, and in the age group 21 years and older, it was radicular cyst. 31.5% of the lesions were associated with impacted teeth, and the most common impacted tooth was the third molar, with a frequency of 58.2%. The clinical and radiological diagnosis was consistent with the histopathological diagnosis in 292 cases (68.2%).
Conclusion: The results of the present study showed that odontogenic lesions have a considerable frequency, and many lesions were observed in association with impacted teeth. Therefore, the presence of an impacted tooth can be considered a potential risk factor for the presence of odontogenic lesions. |
