fa A prospective epidemiological study for odontogenic and non-odontogenic lesions of the maxilla and mandible in Queensland پاتولوزی دهان، فک و صورت Oral and Maxillofacial Pathology پژوهشي Research <p> <strong>Objectives </strong></p><p> Investigate the epidemiological profile for odontogenic and non-odontogenic intra-osseous lesions in the Queensland population (4.56 million) over 12 months. </p><p> <strong>Study Design</strong> </p><p> 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. </p><p> <strong>Results</strong></p><p>  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). </p><p> <strong>Conclusions</strong></p><p>  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. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p> <a href="http://www.oooojournal.net/article/S2212-4403(13)00044-8/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1586&slc_lang=fa&sid=1 Nigel R.Johnson 10031947532846007346 10031947532846007346 Yes Maxillofacial Department, Royal Brisbane and Womens' Hospital, Brisbane, Queensland, Australia Neil W.Savage 10031947532846007347 10031947532846007347 No Oral Pathology and Oral Medicine, Maxillofacial Department, Royal Brisbane and Womens' Hospital, Brisbane, Queensland, Australia Stauros Kazoullis 10031947532846007348 10031947532846007348 No Maxillofacial Department, Royal Brisbane and Womens' Hospital, Brisbane, Queensland, Australia Martin D.Batstone 10031947532846007349 10031947532846007349 No Maxillofacial Department, Royal Brisbane and Womens' Hospital, Brisbane, Queensland, Australia
