Abstract
Adenomatoid odontogenic tumor (AOT) is a rare odontogenic origin tumor that manifests as a slow-growing cystic neoplasm in the anterior maxilla, often in conjunction with an impacted tooth. AOTs are divided into three kinds based on their histology: follicular, extrafollicular, and peripheral. Because the source of the AOT is unknown, it's impossible to say whether the lining of an associated cyst reflects the cause i.e. a real dentigerous cyst, a cystic alteration within an AOT, or a separate entity. The diagnosis and treatment should be determined following a thorough clinical, radiographic, and histological investigation. The presented case is a rare occurrence of its sort due to the favorable patient's age and the AOT's site in the lower jaw. The current study reports on a case with follicular AOT in the anterior mandibular region (a rare location), with unusual histomorphology (snow flake and calcified areas) associated with impacted 43 and retained 83.
Highlights
The most alluring and extremely puzzling hamartomatous malformations, which have been described under a variety of terminologies till the recent years is Adenomatoid Odontogenic Tumor (AOT)
There are very few reports of odontogenic tumors either arising from or associated with odontogenic cysts. Such unusual lesions must be carefully diagnosed by an oral physician in order that absolute best treatment needs of the patient are often met. The purpose of this case report is to present a rare case of AOT that originated in the wall of a dentigerous cyst in mandible with an emphasis on radiographic findings and with pathologic correlation
AOT is known as “tumor of two-thirds” as its incidence is two-thirds cases in the maxilla, of all cases 2/3 females are involved and in 2/3 cases it is associated with the unerupted tooth[5].In the present case, the patient was a female in the second decade with animpacted canine

The most alluring and extremely puzzling hamartomatous malformations, which have been described under a variety of terminologies till the recent years is Adenomatoid Odontogenic Tumor (AOT). Such unusual lesions must be carefully diagnosed by an oral physician in order that absolute best treatment needs of the patient are often met The purpose of this case report is to present a rare case of AOT that originated in the wall of a dentigerous cyst in mandible with an emphasis on radiographic findings and with pathologic correlation. The internal structure of lesion is mixed type with corticated margins, with the area of multiple, discrete radio opaque flecks (snowflakes) which were dispersed in mid apical alveolus region On this sagittal section, the hyperdense flecks are noticed throughout the lesion but were more profound at the level of mid third root of the impacted tooth. After the confirmation further treatment was planned with the enucleation of the lesion along with extraction of 83and orthodontic extrusions of 43
