What is the most common location for an Adenomatoid Odontogenic Tumor?

Adenomatoid Odontogenic Tumors (AOT) are benign tumors that predominantly occur in the dental follicle associated with developing teeth. They are most commonly found in the anterior maxilla, which corresponds to the area around the incisors and canines. The propensity of AOTs to arise in this location is thought to be related to the developmental and dental structures in this region.

The anterior maxilla is not only the most likely site for AOTs but also reflects the general pattern seen with odontogenic tumors, where the anterior regions of the maxilla are more frequently involved. This location allows for clear radiographic identification, typically presenting as a well-defined radiolucency associated with the crowns of unerupted teeth, primarily canines.

In contrast, the posterior maxilla and mandible are less commonly associated with AOTs, as these tumors have a marked preference for the anterior maxilla. The midline of the mandible is also not a typical site for AOTs, and tumors in this region are more closely linked to other odontogenic or non-odontogenic conditions. Thus, the anterior maxilla stands out as the most common and characteristic location for an Adenomatoid Odontogenic Tumor.
