OBJECTIVES: Investigate the epidemiological profile for odontogenic and non-odontogenic intra-osseous lesions in the Queensland population (4.56 million) over 12 months.
STUDY DESIGN: The following data were prospectively collected from all Queensland histopathology laboratories in 2011: gender, age at diagnosis, location of lesion, histopathological diagnosis of the lesion and the patient's postcode.
RESULTS: Six-hundred and thirty-three lesions were collected, comprising 540 odontogenic cysts and 93 odontogenic tumors. Radicular cyst was the most frequently diagnosed lesion (247/540, 45.7%). The overall incidence of odontogenic tumors was 20.4/million. Keratocystic odontogenic tumor was the highest (15.1/million), followed by ameloblastoma (2.41/million) with odontoma and calcifying cystic odontogenic tumor having the same incidence (1.1/million). The 39 non-odontogenic intra-osseous lesions had an overall incidence of 8.55/million. Nasopalatine cysts had an incidence of 2.19/million, followed by fibrous dysplasia and central giant cell granuloma (1.97/million).
CONCLUSIONS: Odontogenic tumors are 5 times less common than cysts. Non-odontogenic lesions are rare, with benign lesions 6.8 times more common than malignant lesions.
