2. New WHO odontogenic tumor classification: impact on prevalence in a population
Abstract Objectives: This study approaches the history of reclassifications and redefinitions around the odontogenic keratocyst (OK), as proposed by the World Health Organization (WHO), and aims to understand the impact of those changes on the prevalence and epidemiology of odontogenic tumors (OTs). Methodology: Cases of OTs diagnosed in an Oral Pathology

3. Análise imuno-histoquímica de Ki-67 e α-SMA em ceratocisto odontogênico, ameloblastoma e folículo pericoronário
Resumo Introdução Os ameloblastomas (AM) são considerados os tumores odontogênicos mais comuns da cavidade bucal, apresentando grande importância clínica devido à sua agressividade, capacidade infiltrativa e comportamento recorrente. De maneira semelhante, o ceratocisto odontogênico (CO) desperta a atenção por ter um comportamento agressivo e alta

4. The mechanism: how dental resorptions occur in ameloblastoma
RESUMO As reabsorções radiculares “em plano” ou “em corte” são características do ameloblastoma e foram consideradas patognomônicas dessa lesão, diferenciando-o do cisto ósseo simples, queratocisto odontogênico e do cisto nasopalatino - nos quais elas estão ausentes, nos dentes envolvidos. Apesar dessa frequência elevadíssima e importante

5. Peripheral odontogenic fibroma in the mandibular gingiva: case report
RESUMO Fibroma odontogênico periférico (FOP) é uma neoplasia benigna rara, de origem mesenquimal odontogênica, representando aproximadamente 4,7% de todos os tumores odontogênicos. Este artigo relata o caso de uma mulher de 29 anos de idade que se apresentou com um nódulo avermelhado, indolor, na gengiva mandibular vestibular direita, entre o segundo p

6. Application of endoscopy to treat mandibular keratocystic odontogenic tumors
The aim of this study was to evaluate the feasibility of endoscopy to remove keratocystic odontogenic tumors (KCOTs) with virtual 3D mandibular images. Fifteen patients (mean age, 40.27±14.58 years) who underwent endoscopic mandibular KCOT enucleation between May 2009 and October 2009 were included. Virtual 3D mandibular reconstructions derived from compute

7. Analysis of GLUT-1, GLUT-3, and angiogenic index in syndromic and non-syndromic keratocystic odontogenic tumors
Abstract The aim of this study was to evaluate the immunoexpression of glucose transporters 1 (GLUT-1) and 3 (GLUT-3) in keratocystic odontogenic tumors associated with Gorlin syndrome (SKOTs) and non-syndromic keratocystic odontogenic tumors (NSKOTs), and to establish correlations with the angiogenic index. Seventeen primary NSKOTs, seven recurrent NSKOTs,

8. Expression of CD90 and P75NTR stem cell markers in ameloblastomas: a possible role in their biological behavior
Abstract Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evalu

9. Syndrome in question: Gorlin-Goltz syndrome
Abstract: The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standard

10. Peripheral Ameloblastoma with Dystrophic Calcification: An Unusual Feature in Non-Calcifying Odontogenic Tumors
Ameloblastoma periférico é a contraparte rara extraóssea do ameloblastoma central, que ocorre em tecidos moles e pode causar reabsorção da crista óssea. Este estudo reporta um ameloblastoma periférico localizado na gengiva vestibular de um homem de 56 anos de idade, que apresentava extensas áreas de metaplasia escamosa, queratinização e calcificaç

11. Morphometric evaluation of keratocystic odontogenic tumor before and after marsupialization
The aim of the present study was the morphometric evaluation of the epithelial lining and fibrous capsule in histological specimens of keratocystic odontogenic tumors (KOTs) before and after marsupialization. Histological sections from six KOTs that had undergone marsupialization followed by enucleation were photographed. The thickness and features of the ca

12. Odontogenic tumors: a 14-year retrospective study in Santa Catarina, Brazil
Odontogenic tumors (OTs) are lesions that develop exclusively on maxillary bones, and form a heterogeneous group. They vary from hamartomatous lesions to benign and malign tumors. Although they are rarely observed in dentistry clinics, it is extremely important for the dentist to be aware of them. The aim of this study was to investigate the incidence of odo
