Summary
Synchronous odontogenic tumors (SOTs) most commonly affect both jaws simultaneously. Odontomas were the most frequent SOT type, with an overall recurrence rate of 13.3%.
Area of Science:
- Oral and Maxillofacial Surgery
- Pathology
- Oncology
Background:
- Synchronous odontogenic tumors (SOTs) are rare, involving the simultaneous occurrence of two or more odontogenic tumors.
- Understanding their demographic and clinical characteristics is crucial for diagnosis and management.
Approach:
- A systematic review was conducted, searching major databases (PubMed, Web of Science, Scopus, EMBASE) for case reports and series on SOTs.
- Descriptive statistical analysis was performed on 30 cases from 28 studies.
Key Points:
- SOTs predominantly occur simultaneously in the maxilla and mandible (63.3%).
- Odontomas were the most frequent SOTs (33.3%), followed by squamous odontogenic tumors and calcifying epithelial odontogenic tumors (26.7% each).
- The overall recurrence rate was 13.3%, with synchronous calcifying epithelial odontogenic tumors showing the highest recurrence (25%).
Conclusions:
- Synchronous odontogenic tumors predominantly affect both jaws simultaneously and are often multifocal.
- Odontomas are the most common type of SOT.
- While overall recurrence is relatively low, specific types like calcifying epithelial odontogenic tumors exhibit higher recurrence rates. A small percentage of cases are associated with syndromes.
