Early diagnosis of Gorlin-Goltz syndrome: case report.

The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by keratocystic odontogenic tumors (KCOT) in the jaw, multiple basal cell nevi carcinomas and skeletal abnormities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the KCOTs are usually one of the first manifestations of the syndrome. This article paper reports the case of a patient, a 10-year-old boy with NBCCS, emphasizing its clinical and radiographic manifestations. This study highlights the importance of health professionals in the early diagnosis of NBCCS and in a preventive multidisciplinary approach to provide a better prognosis for the patient.

Mortality from oral cancer in Aracaju/SE, Brazil: 2000-2009

INTRODUCTION: The incidence of oral cancer varies widely in the world, with two thirds of cases diagnosed in developing countries. OBJECTIVE: To investigate the epidemiology of deaths from oral cancer and the spatial distribution in the city of Aracaju in the state of Sergipe between 2000 and 2009. MATERIAL AND METHOD: Data were collected using the Mortality Information System (MIS) of Aracaju/SE at the DATASUS website and were tabulated using the software TABWIN 3.4. The geographic distribution of deaths by neighborhoods of that city was visualized. RESULT: Of the 78 deaths, 61 (78.2%) were male. The mean age was 64.23 years. Individuals of mixed ethnicity had a higher death frequency (34.6%). Regarding education, the majority of death certificates recorded the option ignored, followed by individuals with 1 to 3 years of study. The anatomical sites most affected were unspecified parts of the mouth (43.6%). The spatial distribution analysis indicated that neighborhoods such as Santos Dumont, Luzia, Atalaia, Santa Maria, Cidade Nova and Industrial had the highest death frequencies. CONCLUSION: Males between the fifth and sixth decades of life of mixed ethnicity, low education and in neighborhoods with low and very low standards of living constitute the epidemiological profile for deaths from oral cancer.

Caso familiar de nevo branco esponjoso oral: uma rara condição hereditária

White sponge nevus (WSN) is an autosomal dominant skin disorder characterized by white, corrugated and diffuse plaques mainly affecting the oral mucosa. The condition has a high penetrance and variable expressivity, but familial reports are uncommon. This report presents a familial case of WSN in which two sisters are affected by the disorder.

High prevalence of human papillomavirus (HPV) in oral mucosal lesions of patients at the Ambulatory of Oral Diagnosis of the Federal University of Sergipe, Northeastern Brazil

Abstract The role of human papillomavirus (HPV) in oral carcinogenesis is still controversial as detection rates of the virus in oral cavity reported in the literature varies greatly. Objective The aim of this study was to evaluate the frequency of HPV infection and its genotypes in patients with oral lesions at the Ambulatory of Oral Diagnosis of the Federal University of Sergipe, Brazil. Material and Methods We conducted a molecular study with 21 patients (15 females) aged from two to 83 years with clinically detectable oral lesions. Samples were collected through exfoliation of lesions and HPV-DNA was identified using MY09/11 and GP5+/6+ primers. Genotyping was performed by multiplex PCR. Results Benign, premalignant and malignant lesions were diagnosed by histopathology. HPV was detected in 17 samples. Of these, HPV-6 was detected in 10 samples, HPV-18 in four and HPV-16 in one sample. When samples were categorized by lesion types, HPV was detected in two papilloma cases (2/3), five carcinomas (5/6), one hyperplasia (1/1) and nine dysplasia cases (9/11). Conclusion Unlike other studies in the literature, we reported high occurrence of HPV in oral lesions. Further studies are required to enhance the comprehension of natural history of oral lesions.

Análise da resistência à fadiga entre pilares retos sólidos e anatômicos do sistema cone morse

Contexto O estudo do fenomeno de fadiga e essencial porque as falhas de implantes geralmente sao causadas por este processo. Objetivo O objetivo deste estudo foi analisar a resistencia a fadiga de conjuntos de pilares retos e anatomicos que foram submetidos a cargas ciclicas. Material e metodo Foram utilizados 37 implantes cone Morse e 37 pilares, divididos em dois grupos (n = 16: pilares retos, n = 21: pilares anatomicos). Os conjuntos foram submetidos a carga ciclica (5.000.000) usando o equipamento servo-hidraulico. Tres conjuntos de cada grupo foram submetidos a testes de flexao para determinar a resistencia de carga maxima, o que serviu de parâmetro para comparacao dos testes ciclicos. Foram avaliados numero de ciclos, carga e momento de flexao. Resultado Dos 31 pilares ciclicamente testados, 17 (54,8%) fraturaram em menos de 5 milhoes de ciclos; 8 (25,8%) destes eram pilares retos, e 9 (29%) eram anatomicos. Um total de 14 amostras (45,2%) resistiu a carga ciclica. De acordo com o teste exato de Fisher, nao houve diferenca entre os grupos quanto a fratura. Conclusao Apesar dos pilares retos terem maior carga media e momento de flexao que os anatomicos, os dois tipos de pilares apresentaram desempenho semelhante quanto a resistencia a fratura in vitro.

Análise da resistência à fratura entre pilares retos e angulados do sistema cone Morse

Objective The aim of this study was to verify the fatigue fracture resistance of the implant-abutment joint, in straight and angled types, subject to cyclic loads similar to chewing. Material and method It was used 32 implants system (3.75 × 11mm) with Morse taper and 32 abutment, divided in two groups: abutment straight and angled (n = 16) (Neodent, Curitiba, PR, Brazil). The sets were submitted to cyclic testing using servo-hydraulic equipment, fixing the number of cycles at 5 million. It was evaluated the number of cycles, load and moment force of the samples. The Fisher test and ANOVA were applied (p<0,005). Fractured samples were analyzed in the scanning electron microscopy (SEM). Result Straight abutment, four resisted the cycles number established, supporting loads between 470N and 510N. Angled abutment: nine resisted to loads between 570N and 890N. Regarding the fractured samples below the number of cycles, in the straight abutment, nine fractured with loads between 470N and 630N. In the angled abutment, five fractured with loads ranging from 760N and 890N. The moment of the force was calculated for each joint implant-abutment (Averages: Straight Group - 4335,23Nmm, angled Group - 3923,37Nmm). Conclusion Two types of abutments (straight and angled), in vitro conditions, statistically behaved similarly, and accepts the null hypothesis that there is no difference in fracture resistance between groups.

PRÉ-MOLAR RETIDO: RELATO DE CASO

Paciente P. T., genero feminino, 17 anos, compareceu ao Centro Universitario de Maringa – CESUMAR por indicacao ortodontica para extracao de dente retido em regiao de corpo de mandibula do lado direito, proximo ao apice dos pre-molares. Foi realizado exame clinico e solicitado exame radiografico intrabucal, sendo detectada a presenca de um segundo pre-molar retido e segundo molar deciduo irrompido com ausencia de rizolise. Sendo assim, por indicacao ortodontica optou-se pela remocao do pre-molar retido, devido a impossibilidade de tracionamento ortodontico. Atraves desta salientamos a importância da apuracao detalhada durante o exame clinico e radiografico onde a decisao de se manter ou nao o dente em questao, foi decisiva para o tratamento e prognostico. Palavras-chave: Dente Impactado; Dente Deciduo; Ortodontia.

CARCINOMA MUCOEPIDERMÓIDE: RELATO DE UM CASO COM 5 ANOS DE EVOLUÇÃO

O Carcinoma Mucoepidermoide e um dos mais comuns tumores malignos das glândulas salivares. E mais frequente na glândula parotida e, usualmente, se apresenta como uma tumefacao assintomatica. As glândulas salivares menores constituem o segundo sitio mais comum, especialmente no palato. Paciente D.A., 37 anos, sexo masculino, lavrador, compareceu a Clinica de Lesoes Bucais do Cesumar, queixando-se de um “caroco no ceu da boca”. Ao exame fisico intrabucal, observamos uma tumefacao no palato duro, deslocada para o lado esquerdo, firme a palpacao, recoberta por mucosa integra, de superficie lisa, com mancha ligeiramente acastanhada, medindo aproximadamente 3cm e exibindo formato ovalado e base sessil. A lesao evoluia de forma assintomatica, ha cerca de cinco anos. O diagnostico presuntivo foi Adenoma Pleomorfico. Foi realizada puncao aspirativa e duas biopsias incisionais, sendo a ultima conclusiva para Carcinoma Mucoepidermoide. Essa hipotese diagnostica deve ser considerada pelo clinico, mediante tumefacoes de palato duro, ainda que o tempo de evolucao seja longo, como no caso em questao.
