When resecting a lesion for CEOT, what is the required anatomical margin?

• A. 0.5 cm
• B. 1 cm
• C. 1.0 to 1.5 cm
• D. 2 cm

Answer: (C)

For the resection of a cemento-osseous tumor (CEOT), also known as a calcifying epithelial odontogenic tumor, the standard recommendation is to achieve an anatomical margin of 1.0 to 1.5 cm. This margin is crucial to ensure that any potentially infiltrative tumor cells are removed, as CEOT can have a tendency to be locally aggressive despite its benign classification. The rationale for maintaining this specific margin is based on the histological characteristics of CEOT, which may extend beyond what is visible at the surface or in imaging studies. Achieving a 1.0 to 1.5 cm margin helps to minimize the risk of local recurrence, which is a significant concern in the management of this tumor. Additionally, adequately wide margins are essential to ensure clear surgical margins are achieved; this has been well-documented in the literature regarding the outcomes of tumor resections. While narrower margins, such as 0.5 cm or 1 cm, might seem sufficient for other benign lesions, the specific behavior and the local infiltration potential of CEOT necessitate a more conservative approach with wider margins to ensure complete excision. A 2 cm margin may be excessively cautious in some instances, given that achieving a balance between adequate
