This case report aims to increase awareness of how an adenomatoid odontogenic tumour (AOT) can present in a similar fashion to a dentigerous cyst and the importance of accurate histopathological diagnosis. In this case, the AOT resulted in loss of the upper left permanent canine in a patient who already had a congenitally absent upper left second premolar, compromising the original orthodontic treatment plan.

Unilocular radiolucent lesions of the dental hard tissues can present regularly, however they are impossible to diagnose definitively without appropriate imaging and histopathology. A case is reported that involves a 14-year-old that presented with a history of an unerupted maxillary first premolar. An initial Dental Panoramic Tomograph (DPT) did not identify any localized opacities and was diagnosed as a dentigerous cyst. A Cone Bean Computed Tomogram (CBCT) identified calcified opacities resulting in a re-evaluated radiological interpretation. With the help of a multidisciplinary approach, the removal of the benign lesion allowed orthodontic traction to extrude the tooth and for it to be brought into alignment. CPD/Clinical Relevance: This report highlights the importance of three-dimensional imaging as an adjunct to aid diagnosis and highlights the importance of multidisciplinary teams in the management of clinical challenges.

Adenomatoid Odontogenic Tumour (AOT) is a relatively uncommon benign odontogenic tumour composed of odontogenic epithelium in a variety of histoarchitectural patterns. Conventional AOT is predominantly seen in females in second decade of life exhibiting predilection for anterior region of maxilla. Very few cases of AOT associated with dentigerous cyst have been reported till date. The present case is unique associated with an impacted lower first premolar in the front region of the mandible of an 18-year-old female patient. The patient reported to the institute with gradually increasing swelling. The orthopantomogram revealed a unilocular radiolucency with displaced premolar. Histopathological examination confirmed 4×2.5×2 cm lesion in dimension, brownish black in colour, firm in consistency with a smooth surface grossly while cut surface revealed a cystic lumen with an impacted premolar embedded into the lining, cystic wall being nodular. Microscopic evaluation revealed a well encapsulated lesion with a thin 2-3 cell layered non keratinised stratified epithelial lining in patterns such as nests, rosette like structures and duct like structures. Thus the diagnosis of AOT arising from dentigerous cyst was confirmed. Patient's six month follow-up was uneventful. Literature search of similar cases with the review of hypothesised aetiopathogenesis is discussed in brief. The available data can help researchers resolve the uncertainty whether the AOT derived from dentigerous cyst could represent a distinct hybrid variety.

Adenomatoid odontogenic tumour (AOT) is a rare tumour of odontogenic origin with distinct clinicopathological appearance but is often clinically misdiagnosed as a cyst. The most common site is the anterior maxilla in the canine region. We present here two cases, one at its commonest location in the maxillary canine while the other is at the uncommon location of the anterior mandible. Its clinical features of painless slow growing swelling, association with impacted tooth and radiographic appearance of well defined predominantly radiolucent lesion are overlapping with other oral pathologies like dentigerous cyst, radicular cyst, calcifying odontogenic cyst, calcifying epithelial odontogenic tumour, unicystic ameloblastoma etc. One must be aware and updated with the variation in appearance of AOT. Encapsulation of tumour causes less cumbersome enucleation of the tumour, a successful treatment as it reduces the chances of recurrence.

The adenomatoid odontogenic tumor (AOT) is a relatively uncommon lesion which mainly affects females in their second decade of life, exhibiting predilection for the anterior region of the maxilla. The lesion is usually associated with the crown of an enclosed tooth, most commonly the maxillary canine. In this paper we present a case of adenomatoid odontogenic tumor associated with a dentigerous cyst affecting the left maxilla in a 15-year-old female. We also discuss clinical, radiographic, histopathologic, and therapeutic features of the case.

Background: Odontogenic maxillary cysts and tumours originate from the tooth root and have traditionally been treated through an intraoral approach. Here, we report the efficacy and utility of endoscopic modified medial maxillectomy (EMMM) for the treatment of odontogenic maxillary cysts and a tumour. Methodology: We undertook EMMM under general anaesthesia in six patients: four had radicular cysts, one had a dentigerous cyst, and one had a keratocystic odontogenic tumour. Results: The cysts and tumours were completely excised and the inferior turbinate and nasolacrimal duct were preserved in all patients. There were no peri- or postoperative complications, and no incidences of recurrence. Conclusion: Endoscopic modified medial maxillectomy appears to be an effective and safe technique for treating odontogenic cysts and tumours.
