An expanded and revised early history of the adenomatoid odontogenic tumor.

Adenomatoid odontogenic tumor (AOT) is not a new entity and has long been a subject of fascination after a century of recorded observation because of its unique biological profile. Hundreds of publications have covered a variety of aspects, ranging from demographic data to clinicopathologic features to treatment modalities. It is widely acknowledged that the first detailed reports of AOT were initially published in 1915 by Harbitz in Norway and later in 1916 by Wohl in the United States. However, it is very likely that earlier textbook and journal descriptions of AOT exist. This prompted us to review the extensive world literature on AOT dating back to the early part of the 19th century. Here we present a revised historical perspective of AOT, with a view to closing gaps in earlier knowledge about this entity and also encouraging further research.

Classification of odontogenic tumours. A historical review.

Using the term odontome for any tumour arising from the dental formative tissues, Broca suggested a classification of odontogenic tumours (OTs) in 1869. From 1888 to 1914, Bland-Sutton and Gabell, James and Payne modified tumour terminology, while maintaining Broca's odontome concept. Thoma and Goldman's classification (1946) divided the OTs into tumours of ectodermal, mesodermal and mixed origin and abolished the general term odontome. The Pindborg and Clausen classification (1958) based on the idea that the reciprocal epithelial-mesenchymal tissue interactions were also operating in the pathogenesis of OTs. In 1966, WHO established a Collaborating Centre for the Histological Classification of Odontogenic Tumours and Allied Lesions (including jaw cysts) headed by Dr Jens Pindborg. In 1971, the first authoritative WHO guide to the classification of OTs and cysts appeared followed in 1992 by a second edition. In 2002, Philipsen and Reichart produced a revision of the 1992-edition and in 2003, the editors of the WHO Blue Book series: 'WHO Classification of Tumours' decided to produce a volume on the Head and Neck Tumours including a chapter on Odontogenic Tumours and Bone Related Lesions. In July of 2005 this volume was published by IARC, Lyon.

Tumores odontogénicos: análisis de la producción científica / Odontogenic tumors: an analisys of the scientific production

Objetivo: Presentamos el análisis estadístico descriptivo y bibliométrico de las fuentes bibliográficas relacionadas con los tumores odontogénicos. Material y método: Nuestra muestra es fruto de la consulta de 31 repertorios nacionales e internacionales, accesibles desde las instalaciones de la Universidad de Sevilla. Los datos fueron analizados atendiendo a la base de datos que se encontró, país de origen, lengua, año de publicación y materia. Se indagó también la validez de las leyes de Price, Bradford y Lotka en estas reseñas. Resultados y conclusiones: Los resultados más importantes son el predominio de los EE.UU. como principal nación en la producción actual de trabajos sobre tumores odontogénicos y la equiparación de Europa Occidental y América del Norte en cuanto a artículos publicados. Los datos extraídos cumplen fielmente los postulados de Bradford y Lotka (coeficiente de correlación = 0,99), pero no los de Price (índice de correlación = 0,145), detectándose un estancamiento del crecimiento de la producción científica en esta área (AU)

Squamous odontogenic tumor-like proliferation in residual cyst: case Report / Proliferação odontogênica escamosa semelhante à tumor em cisto residual: relato de caso

A case of squamous odontogenic tumor-like proliferation (SOT-LP) in residual cyst is described. Based on clinico-pathological data, the relationship to the relationship to the squamous odontogenic tumor (SOT) was analyzed. The possibility of SOT-LP representing an early manifestation of the squamous odontogenic tumor was discussed

The beginning of oral pathology. Part I: First dental journal reports of odontogenic tumors and cysts, 1839-1860.

Literature reviews of oral lesions frequently lack an appropriate historic perspective, presuming that the mid- to late-twentieth century reports are the first valid reports available. The mid-nineteenth century dental journals, however, are replete with clinical, surgical, and microscopic descriptions of oral tumors and cysts. Most of these have never been referenced during the present century. The purpose of this article is to report the earliest dental journal references for a variety of odontogenic tumors and cysts. These references are derived from a canvass of all dental journals published from the first journal (American Journal of Dental Science) in 1839 to the appearance of Dental Cosmos and the organization of the American Dental Association in 1860.

[20 years' experience in stomato-oncology]. / Húsz éves tapasztalataink a stomatoonkológiában.

Between 1970 and 1988, 8,657 out of 102,113 out-patients at the Clinics of Dentistry and Oral Surgery of Szeged had stomatooncological illness. Documentation of the patients is carried out on data-forms suitable for computer processing. One of the most important tasks of stomatooncology consists in effecting screening test in which the basic dental care has a decisive role. It is a deficiency sign of the oncological view that even the precancerous oral cavity conditions and conspicuous tumors don't get timely into the centres, and, also, treatments are carried out without histological biopsy. Since 1973, 4,038 patients have been treated with cryotherapeutic methods and such method did deemed primary independent treatment in case of well selected patient stocks. The oncological complex therapy has to be followed by looking after. Yearly 1,500 to 2,000 check ups are effected.
