Abstract

Abstract: This article aims to alert clinicians to the presentation and management of the adenomatous odontogenic tumour (AOT). AOTs are unusual benign lesions, often associated with unerupted teeth. They commonly present in the second decade of life and may be particularly relevant to the orthodontist and general dental practitioner, as they may coincide with the age of referral for impacted teeth. The AOT can encapsulate the crown and root of the tooth, resulting in bucco-lingual expansion and can be relatively painless with few or no subjective symptoms. It is important to be aware of this lesion in the maxillofacial region to ensure correct management of this tumour and involvement of any associated teeth.

CPD/Clinical Relevance: It is important for referring practitioners to be aware of the multifactorial aetiology of impacted teeth and the timeliness of referral. These anomalies require a multidisciplinary input from both the orthodontic and oral and maxillofacial team. The tumour can result in a three-dimensional thinning of the alveolar bone, resulting in an overall poor long-term prognosis of any involved teeth, particularly during orthodontic alignment.

Article

The adenomatoid odontogenic tumour (AOT) is an uncommon benign tumour, originally described by Steensland in 1905,1 although it was not recognized as an odontogenic neoplasm until 1948.2 A variety of terms have been used to describe this tumour:3

The World Health Organization histological typing of odontogenic tumours has described the AOT as follows: ‘A tumour of odontogenic epithelium with duct-like structures with varying degrees of change in the connective tissue. The tumour may be partly cystic and in some cases a solid lesion may be present only as masses in the wall of a large cyst. It is believed that the lesion in not a true neoplasm’.4

The frequency of AOT accounts for approximately 2.9−6.8% of all odontogenic tumours.4 This tumour ranks fifth among odontogenic tumours in the oro-maxillofacial region.2
