1. Immunohistochemical analysis of SHH, SMO and GLI-1 proteins in epithelial odontogenic lesions
Resumo O presente estudo analisou a expressão de proteínas envolvidas na via de sinalização Sonic Hedgehog (SHH, SMO e GLI-1) em lesões benignas do epitélio odontogênico de comportamento biológico distintos, tais como ceratocistos odontogênicos (CO), ameloblastomas (AMB) e tumores odontogênicos adenomatoides (TOA), com o intuito de identificar o pa

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. 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

4. Reclassification and treatment of odontogenic keratocysts: A cohort study
Abstract: The odontogenic keratocyst (OKC) is a recurrent cyst that has been recently reclassified from an odontogenic tumor to an odontogenic cyst. The aim of the present study was to investigate its treatment and address issues related to its association with nevoid basal cell carcinoma syndrome (NBCCS). Lesions from the cohort of patients included in the

5. Evaluation of the Prevalence of Maxillary Sinuses Abnormalities through Spiral Computed Tomography (CT)
Abstract Introduction Maxillary sinus disease is common and numerous disorders can affect this anatomical area. Abnormalities can be classified as: non-neoplastic, neoplastic benign, and neoplastic malignant. Objective Evaluate through CT the prevalence of diseases in maxillary sinuses, using the Radiology Department’s database of a hospital in São Pa

6. 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

7. 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

8. Cellular proliferation markers in peripheral and central fibromas: a comparative study
Objective: To perform a comparative study of the cellular proliferation in the peripheral and central fibromas. Material and Methods: Immunohistochemistry for PCNA and the AgNOR technique were performed in 9 cases of peripheral odontogenic fibroma (POF), in 4 cases of odontogenic fibroma (OdF), in 8 cases of peripheral ossifying fibroma (PEOF) and 7 cases

9. 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

10. Evaluation of the cell block technique as an auxiliary method of diagnosing jawbone lesions
This study investigated the viability of the cell block technique as an auxiliary method of diagnosing jawbone lesions. Thirty-three clinically diagnosed jawbone lesions with a cystic appearance were subjected to aspiration. The aspirated material was processed by the cell block technique, and the lesions were biopsied and treated. Cytological findings (cell

11. 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

Avaliação do tipo de tratamento realizado para as lesões ósseas : cisto ósseo simples, lesão central de célular gigantes e queratocisto odontogênico : análise retrospectiva / Evaluation of type of treatment done in bone injuries : simple bone cysts, central giants cells lesions and odontogenic keratocysts : a retrospective analysis
O objetivo deste trabalho foi avaliar separadamente a eficácia do tratamento realizado pelo serviço de cirurgia bucomaxilofacial da FOP-UNICAMP em três lesões ósseas que podem acometer a região maxilofacial: cisto ósseo simples (COS), lesão central de células gigantes (LCCG) e queratocisto odontogênico (QO). 1) 12 casos de COS, sendo a curetagem o
