1. 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

2. Dental pulp stem cells express proteins involved in the local invasiveness of odontogenic myxoma
Little is known about the histogenesis of the odontogenic myxoma (OM). Dental pulp stem cells could be candidate precursors of OM because both OM and the dental pulp share the same embryological origin: the dental papilla. For the purpose of comparing OM and stem cells, this study analyzed the expression of two proteins related to OM invasiveness (MMP-2 and

3. Hypomethylation of tumor suppressor genes in odontogenic myxoma
O mixoma odontogênico (MO) é um tumor odontogênico benigno de origem mesenquimal caracterizado pela presença de células fusiformes ou estreladas dispostas em abundante matriz extracelular mucóide. A metilação do DNA é caracterizada pela adição de grupos metil em citosinas constituintes de ilhas CpG na região promotora do gene. A metilação pode

4. Análise in vitro da expressão de proteínas da matriz extracelular (MEC) e de metaloproteinases da matriz (MMPs) em células-tronco adultas de polpa dentária humana / Analysis of ECM proteins and MMPs expression in human dental pulp stem cells
Células-tronco adultas podem ser isoladas de vários tecidos, dentre eles a polpa dentária humana, tecido originado na papila dentária do dente em desenvolvimento. Estas linhagens multipotentes podem ser estudadas sob vários aspectos, como na elucidação da histogênese de tumores. O objetivo deste estudo foi inferir a histogênese do mixoma odontogêni

5. Expressão imuno-histoquimica de colagenase-1 e gelatinases A e B em mixomas odontogênicos e papilas de germes dentários
The odontogenic myxoma shares cellular and structural aspects with dental papilla, which has been implicated as probable origin of this neoplasm. The aim of the present study was to perform a comparative immunohistochemical analysis for the expression of collagenase-1 (MMP-1) and gelatinases A (MMP-2) and B (MMP-9) in odontogenic myxomas and dental papilla o

6. Odontogenic myxoma : clinicopathological and immunohistochemical analyse of 67 cases / Mixomas odontogenicos : analise clinicopatologica e imunohistoquimica de 67 casos
The aim of this study was to analyze the immunohistochemical profile and clinical, radiographical and histopathological characteristics of 67 cases of odontogenic myxoma (OM), as well as to report the greatest series related in the world literature. Females were more affected with 48 cases (71,64%) whereas males were in 19 (26.83%), male-female ratio 1:2.5.

7. S100, alpha-smooth muscle actin and cytokeratin 19 immunohistochemistry in odontogenic and soft tissue myxomas.
AIMS--To compare the expression of S100 protein, alpha-smooth muscle actin (alpha-SMA) and keratin 19 in odontogenic myxomas and non-odontogenic myxoid lesions. METHODS--Formalin fixed, paraffin wax embedded tissue from seven odontogenic myxomas, three soft tissue myxomas, six hyperplastic myxoid dental follicles, two intramuscular myxomas, 12 cardiac myxoma

8. Odontogenic myxoma: Ultrastructural and histochemical studies
An odontogenic myxoma of a maxilla has been examined. Histochemistry of the mucosubstance indicated that hyaluronic acid and chondroitin sulphate were present. On ultrastructural examination many of the cells in the myxomatous tissue were seen with prominent rough endoplasmic reticulum, suggesting a secretory function, and possibly the myxomatous ground subs
