Cysts and tumours of the jaw are relatively common. Clinical, radiologic, and pathologic features allow the diagnosis to be made. Cysts and tumours can develop from tooth derivatives (odontogenic) or other tissues (nonodontogenic).
Radicular cysts are by far the most common type of odontogenic cyst and are associated with caries. Dentigerous cysts are the next most common cyst, and they vary in size and may cause massive destruction of the jaw.
Unlike ameloblastomas, dentigerous cysts do not exhibit an extracystic soft-tissue mass, but ameloblastomas, mucoepidermoid tumours, and carcinomas may develop on the wall of a dentigerous cyst.
Onodontogenic cysts include the fissural cyst, solitary bone cyst, and static bone cavity. Cysts are usually small and asymptomatic; however, some may become multiloculated and are difficult to distinguish radiologically from an ameloblastoma
Benign odontogenic tumours include the ameloblastoma, calcifying epithelial odontogenic tumour (Pindborg tumour), odontoma, odontogenic myxoma, and cementoma.
