Oral and maxillofacial pathologyAdenomatoid odontogenic tumors: an analysis of 67 cases in a Thai population
Section snippets
Material and Methods
The histopathologic records of the Department of Oral Pathology, Chulalongkorn University, were reviewed for AOT lesions registered from January 1974 to May 2006. One investigator reevaluated the hematoxylin and eosin stained sections, and the histopathologic diagnosis was made according to the WHO Classification of Tumours.6 Data collected included age, sex, variants of AOT, site and extent of tumors, associated impacted teeth, initial clinical diagnoses, clinical presentations, and duration
Results
The patients were between 6 and 51 years of age at time of diagnosis, with a mean age of 21.1 ± 10.0 years. The mean ages of females and males were not different (20.9 ± 8.3 years and 21.4 ± 12.7 years, respectively; P = .738). The peak incidence of AOT (56.7%) was found in the range of 10 to 19 years of age (Fig. 2).
Of the 1268 cases of odontogenic tumors diagnosed, 67 AOTs were identified (RF = 5.3%). All cases were intraosseous, of which 37 (55.2%) were follicular and 30 (44.8%) were
Discussion
Adenomatoid odontogenic tumor is not a common odontogenic tumor, and it takes time to collect sufficient numbers of representative cases. Therefore, we have only 67 cases on record at the Department of Oral Pathology, Chulalongkorn University, for the past 31 years.
The results of our study agree to a large degree with most studies around the world.9, 16, 17 The RF of AOT among odontogenic tumors in the present study (5.3%) was in the range of previous reports. In comparison with Asian

2020, Journal of Oral and Maxillofacial Surgery, Medicine, and PathologyCitation Excerpt :Furthermore, in considering the treatment options for AOT, preservation of the associated primary tooth cannot be recommended when expecting its subsequent eruption. A review of literature identified only nine previously reported cases of an AOT associated with an unerupted primary tooth (Table 1) [4–12]. Among these cases, girls were more prevalent than boys, similar to the tendency observed in previous reviews [3,13].

2020, Journal of Oral and Maxillofacial Surgery, Medicine, and PathologyCitation Excerpt :AOT is a benign, slow growing entity which cause wide confusions regarding nomenclature and the pathogenesis, in the literature [10]. It is still not clear as to whether AOT is a hamartoma or a true neoplasm [4,10,11]. Various theories regarding the origin of the AOT have mentioned in the literature previously.
