Adenomatoid odontogenic tumour (AOT) is the fourth most common odontogenic tumour. It is benign and slow growing, comprising of three variants; follicular, extrafollicular, and peripheral. A follicular variety of AOT will be associated with an impacted tooth and is most commonly confused with a dentigerous cyst. It is a known fact that odontogenic cysts can be associated with odontogenic tumours. There are very few case reports of AOT arising within the dentigerous cyst. Here, we report a case of AOT arising from a dentigerous cyst with an impacted canine in the anterior maxilla of a 14 year-old female with emphasis on clinical, radiographical, and histological features.
