    Abstract:
    OBJECTIVE: The aim of this study was to determine the biologic profile of the adenomatoid odontogenic tumor (AOT) in a Thai population. STUDY DESIGN: Sixty-seven cases of AOT registered from January 1974 to May 2006 were studied retrospectively. Age, sex, variants of AOT, site and extent of tumors, associated impacted teeth, initial clinical diagnoses, clinical presentations, and duration of symptoms were analyzed. RESULTS: All AOT cases were intraosseously located, of which 55.2% were follicular and 44.8% extrafollicular. The 2 variants together were found more frequently in the maxilla than in the mandible, with a ratio of 2:1. Females were affected more often than males, with a ratio of 1.8:1. The peak incidence (56.7%) was found in the second decade of life. The majority of AOT lesions (68.7%) was found in the anterior jaws. Adenomatoid odontogenic tumors were observed more often on the left side of jaws (50.7% vs. 38.8%). Canines were the most common teeth associated with follicular AOT (67.5%), and the maxillary canines alone accounted for 51.3% of all cases. The majority of our patients presented with a painless swelling and with duration of symptoms of 6 months and longer. CONCLUSIONS: The distribution and characteristics of AOT in a Thai population are similar to the findings found in other populations. Interestingly, in this series we observed a case involving an impacted deciduous canine and a case associated with an impacted maxillary third molar.
