A dentigerous cyst is a type of developing odontogenic cyst that surrounds an unerupted tooth's crown. Dentigerous cysts, which make up 20% of all developmental cysts of the jaws, are the most prevalent in the oral cavity. They are caused by fluid buildup between the tooth crown and reduced enamel epithelium. Hence, it is usually associated with an unerupted or impacted tooth. Ameloblastoma, squamous cell carcinoma, and mucoepidermoid carcinoma are among the neoplastic transformations that can occur in the lining of dentigerous cysts. Ameloblastoma is a type of odontogenic tumour that is aggressive locally and makes up around 10% of all jaw tumours. This report describes a 47-year-old male patient who was diagnosed with ameloblastoma that developed in the dentigerous cyst wall.
