Expressão do colágeno I em carcinomas epidermóides da cavidade oral

An analysis of the extracellular matrix at the invasive front of squamous cell carcinoma of the oral cavity may improve the understanding of tumour cell matrix interactions during malignancy growth. Alterations in collagen I expression may influence cellular invasion and metastasis. In this work, 23 cases of squamous cell carcinoma were submitted to the Anneroths malignancy grading system1. H. E. and sirius red staining were used. Immunohistochemical expression of collagen type I protein was observed in different malignancy scores. As a result, it was observed that the extracellular matrix in squamous cell carcinoma of the oral cavity shows different patterns of collagen I expression in low and high scores of malignancy.

Consequências da Radioterapia na Região de Cabeça e Pescoço: Uma Revisão da Literatura

Resumo A radioterapia tem sido uma opcao entre as terapias disponiveis para o tratamento das neoplasias malignas. Porem, apesar de sua eficacia, essa modalidade terapeutica tambem promove alguns efeitos adversos que podem atingir a cavidade oral quando esses tumores estao localizados na regiao de cabeca e pescoco.

Reabilitação Protética em Paciente com Displasia Ectodérmica Hipohidrótica: Caso Clínico

Resumo A Displasia Ectodermica e uma anomalia determinada por fatores geneticos, capaz de alterar as estruturas ectodermicas como os dentes, pele, cabelo, unhas, glândulas sudoriparas e sebaceas. Existem muitas variacoes da Displasia Ectodermica, sendo que, a Displasia Ectodermica Hipohidrotica ou Anidrotica ligada ao cromossomo X e a forma mais conhecida e uma das quais o cuidado odontologico e uma etapa muito importante do tratamento. Este trabalho teve como objetivo relatar um caso clinico de um paciente do sexo masculino, 06 anos de idade, portador de Displasia Ectodermica Hipohidrotica, em que seu tratamento consistiu na confeccao de uma Protese Total, em ambas as arcadas, com a intencao de melhorar suas condicoes esteticas, funcionais e psicologicas. Esse paciente procurou, junto a mae, a disciplina de Estomatologia II da Escola Bahiana de Medicina e Saude Publica com a queixa principal de “falta dos dentes desde o nascimento”. Apos a anamnese, exame clinico e radiografico foi estabelecido o diagnostico de Displasia Ectodermica Hipohidrotica e o paciente foi encaminhado para a disciplina de Protese Total com a finalidade de confeccionar duas Proteses Totais (superior e inferior). O resultado foi o resgate das condicoes esteticas, funcionais e psicologicas do paciente. Frente ao exposto, concluiu-se que o diagnostico e tratamento precoces sao fatores importantes para melhorar as condicoes esteticas, funcionais e psicologicas da crianca, permitindo seu desenvolvimento fisico, emocional e social. Alem disso, a instalacao da Protese Total permitiu uma melhor alimentacao e suspensao do habito de succao digital, constituindo uma alternativa satisfatoria para o tratamento reabilitador.

Prevalence of risk factors for oral diseases in obese patients referred for bariatric surgery

BACKGROUNDnObesity is a risk factor for several chronic diseases, and scientific evidence suggests an association between obesity and oral diseases. In this study, the authors estimated the prevalence of risk factors for caries, dental erosion, and periodontal disease in a group of obese patients referred for bariatric surgery.nnnMETHODSnThe authors invited obese patients who were referred for bariatric surgery at a private center for treatment of obesity to participate in this study. The patients answered a questionnaire about their sociodemographic data, general and oral health histories, dietary habits, and oral health care behavior.nnnRESULTSnThe authors evaluated a total of 255 participants; 200 (78.4%) were women, the median (interquartile range) age was 36.0 (30.0-43.0) years, and the median (interquartile range) body mass index was 39.7 (37.6-43.5) kilograms per square meter. The authors observed a high prevalence of risk factors for dental erosion; 78.4% of the participants consumed acidic foods daily, and 92.2% consumed acidic beverages daily. With respect to risk factors for caries, 38.5% of the participants reported high sucrose intake, and 59.6% preferred sweet beverages and foods with sucrose. Almost 13% of the participants reported having or having had dental mobility, and 59.6% reported having or having had gingival bleeding, suggesting a history of periodontal disease.nnnCONCLUSIONSnObese patients referred for bariatric surgery are exposed to risks of experiencing oral diseases and should be evaluated by a dentist.nnnPRACTICAL IMPLICATIONSnKnowing the risk factors for oral diseases in obese patients is important in raising awareness about these risk factors, as well as to prevent complications in the oral cavity.

Vocational training of dentistry students regarding knowledge of oral rinses with antiseptic

Objective : the indiscriminate use of mouthwash with antiseptic carries health risks because the active pharmacological ingredients and other components of these formulations are not innocuous. From this perspective, it is essential to add this knowledge to the vocational training curriculum for dental students. The objective of this study was to assess the level of knowledge acquired by dental students graduating in 2014 about mouthwash with antiseptic and to evaluate the university education in three public and three private institutions. Methodology : an investigative enforcement tool was used to collect information from graduating students in 2014 from six dentistry undergraduate institutions in the state of Bahia. Results : of the students in private institutions, 56% reported having studied the rinses during their program, while 67% of students in public institutions indicated that they had not. Respondents cited a range of course and disciplines that addressed the topic. Of the students surveyed, 53.1% from public institutions and 46.9% from private institutions reported that they use rinses on a daily basis and expressed a preference for Colgate (50.7%), Oral B (26.4%) and Listerine (16.4%). With regard to knowledge of the active ingredients, 81% students did not answer, despite having general knowledge of diluents. Conclusion : although mouthwash is often included in the course of study, the level of knowledge students achieved was not considered satisfactory, given the high percentage of blank answers regarding active ingredients and indications.
