fa Keratocystic odontogenic tumor: A retrospective analysis of genetic, immunohistochemical and therapeutic features. Proposal of a multicenter clinical survey tool پاتولوزی دهان، فک و صورت Oral and Maxillofacial Pathology پژوهشي Research <p> <strong>Objective</strong></p><p>  In 2005, the World Health Organization reclassified the parakeratinizing odontogenic keratocyst as a neoplasm. This article reviews the research leading to this reclassification, and validates a new survey tool that can be easily used to pool surgical and recurrence data from multiple offices. </p><p> <strong>Study design</strong></p><p>  All odontogenic lesions accessioned in the Iowa Surgical Oral Pathology Laboratory between 1949 and 2010 were identified from the database. A survey tool to assess treatment and follow-up was created. A total of 46 surgeons agreed to participate. </p><p> <strong>Results</strong> </p><p> A total of 70 keratocystic odontogenic tumors (KOTs) had documented recurrences at follow-up intervals ranging from 6 months to 5 years. Primary tumors that recurred ranged in size as measured by greatest radiographic diameter from 0.7 to 6cm. </p><p> <strong>Conclusions</strong> </p><p> This survey tool is recommended as standard allowing treatment of cases by multiple practitioners to be compared retrospectively or prospectively. </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)00178-8/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1662&slc_lang=fa&sid=1 Michael W.
