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. 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

3. 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

4. Keratocystic odontogenic tumor related to nevoid basal cell carcinoma syndrome: clinicopathological study
AIM: To assess clinicopathological features of patients with keratocystic odontogenic tumor (KCOT) associated with nevoid basal cell carcinoma syndrome (NBCCS) in a single Brazilian institution. METHODS: After histopathological analyses of KCOT related to NBCCS, the medical charts of 14 patients were assessed. These patients presented a total of 31 primary a

5. Study of surgical treatment of keratocystic odontogenic tumors associated or not to the nevoid basal cell carcinoma syndrome and analysis of recurrence-free period / Estudo da terapêutica cirúrgica dos tumores odontogênicos queratocísticos associados ou não à síndrome do carcinoma nevóide de células basais e análise do tempo livre de recorrência
O tumor odontogênico queratocístico (TOQ) é uma neoplasia cística benigna originada de remanescentes epiteliais da odontogênese, que se destaca pela alta recorrência e eventual associação com a síndrome do carcinoma nevóide de células basais (SCNCB). O presente estudo buscou responder questionamentos relacionados à sua terapêutica cirúrgica e s

6. Surgical management of dentigerous cyst and keratocystic odontogenic tumor in children: a conservative approach and 7-year follow-up
Dentigerous cyst (DC) is one of the most common odontogenic cysts of the jaws and rarely recurs. On the other hand, keratocystic odontogenic tumor (KCOT), formerly known as odontogenic keratocyst (OKC), is considered a benign unicystic or multicystic intraosseous neoplasm and one of the most aggressive odontogenic lesions presenting relatively high recurrenc

7. Cell proliferation and apoptosis in ameloblastomas and keratocystic odontogenic tumors
Uma elevada atividade proliferativa do epitélio odontogênico em ameloblastoma (AM) e tumor odontogênico ceratocístico (TOC) tem sido demonstrada. Entretanto, não há estudos prévios avaliando simultaneamente os índices de proliferação celular e apoptótico em AM e TOC, comparando ambas as lesões. O objetivo desse estudo foi avaliar e comparar os í

8. Avaliação dos parâmetros clínico, histopatológico e imunoistoquímico dos tumores odontogênicos queratocísticos associados ou não à Síndrome do Carcinoma basocelular nevóide / Evaluation of clinical, histopathological and immunohistochemistry parameters of Keratocystic Odontogenic Tumor associated or not with Nevoid Basal Cell Carcinoma Syndrome
Introdução. O Tumor Odontogênico Queratocístico (TOQC) é uma lesão de origem odontogênica que se apresenta exclusivamente nos ossos gnáticos e possui alto potencial de agressividade local. Pode estar associado à Síndrome do Carcinoma Nevóide Basocelular (SCNBC), que se caracteriza por apresentar inúmeras alterações de desenvolvimento, múltiplo

10. Avaliação da estabilidade biológica do tumor odontogênico queratocístico em diferentes momentos / Biological stability evaluation of the keratocystic odontogenic tumor in different moments
The keratocystic odontogenic tumor is a benign odontogenic tumor recently classified as such by the World Health Organization. The high recurrence rate, the similarity with other odontogenic cystic lesions and the genetic associated mutations continuous stimulate studies intending diagnostic enhancement and behavior understanding of such lesion. The citokera

12. Avaliação histopatológica e expressão imunoistoquímica de PTHrP e receptor de PTH/PTHrP tipo I em cistos radiculares, cistos dentígeros e tumores odontogênicos queratocísticos / Histopathological evaluation and immunohistochemical expression of PTHrP and receptor of PTH / PTHrP type I in radicular cysts, dentigerous cysts and odontogenic tumors keratocystic
O objetivo deste estudo foi analisar as características histopatológicas e expressão imunoistoquímica comparativa de PTHrP e seu receptor PTH/PTHrP tipo I no revestimento epitelial e na cápsula fibrosa de cistos radiculares, cistos dentígeros e tumores odontogênicos queratocísticos. Para tanto, foram analisados 35 casos de cisto radicular, 22 de cist
