Full Text Available O líquen plano é uma desordem comum do epitélio escamoso estratificado que acomete as mucosas oral e genital, a pele, as unhas e o couro cabeludo. O líquen plano oral (LPO afeta mulheres de meiaidade e apresenta padrões e distribuição característicos, como estriações brancas, pápulas ou placas brancas, eritema, erosões e bolhas, que podem estar associadas a medicações e/ou materiais dentários no paciente. O diagnóstico clínico somente poderá ser feito se a doença apresentar padrões clássicos, como lesões concomitantes na mucosa oral e na pele. O diagnóstico laboratorial por meio do exame histopatológico se caracteriza pela presença de projeções do epitélio em forma de dentes de serra e corpos de Civatte, e possibilita excluir condições de displasia e malignidade. A imunofluorescência direta é utilizada em suspeita de outras doenças, como pênfigo e penfigoide. O LPO é tratado com agentes anti-inflamatórios, principalmente, corticosteroides tópicos, e novos agentes e técnicas têm-se demonstrado eficazes. A transformação maligna do LPO e sua incidência exata permanecem controversas. Este trabalho tem como objetivo apresentar, com base na revisão da literatura, a etiopatogenia, o diagnóstico clínico, exames complementares e complicações do LPO.Lichen planus is a common disorder of the stratified squamous epithelium that affects oral and genital mucous membranes, skin, nails, and scalp.

Rodrigo Gadelha Vasconcelos

Full Text Available Introdução: as lesões pigmentadas podem ser encontradas na cavidade oral, essas pigmentações são provenientes de diversos fatores, tais como, locais, sistêmicos, fisiológicos ou patológicos. A cor, localização, distribuição e duração são características essenciais para o diagnóstico destas lesões, não devendo- se negligenciar a história médica, odontológica e familiar, bem como o consumo de drogas. Apesar de algumas lesões apresentarem características bastante específicas que as confere um diagnóstico apenas através do exame clínico, é importante que o profissional lance mão de métodos adicionais, como biópsias e exames laboratoriais, afim de alcançar um diagnóstico confiável e consequentemente, executar o tratamento adequado. Objetivos: essa revisão de literatura tem como objetivo discorrer sobre as principais lesões orais enegrecidas da cavidade oral, enfatizando o diagnóstico diferencial para cada uma delas, já que tal abordagem implicará diretamente na conduta profissional e no estabelecimento do tratamento adequado para cada paciente. Métodos: para isso foi realizada uma revisão de literatura através da busca de artigos no PubMED/Medline, Lilacs e Scielo. Resultados: a literatura estudada destacou que as lesões pigmentadas orais e maxilofaciais podem clinicamente simular o melanoma, uma lesão maligna. Conclusões: devemos ter especial atenção durante o exame clínico deste tipo de ocorrência, saber questionar o paciente para obter informações importantes a respeito da lesão, ter conhecimento dos diferentes tipos de lesões pigmentadas que acometem a cavidade oral e face, assim como ter em mente a necessidade do exame histopatológico para se obter o diagnóstico definitivo de lesões pigmentadas suspeitas.

Full Text Available O presente artigo propõe reflexões sobre as possibilidades de ensino da língua oral, a partir das concepções veiculadas nos Parâmetros Curriculares Nacionais (Brasil do ensino fundamental e de críticas consensuais que evidenciam a carência de materiais didáticos e de currículos que dêem à língua falada e às produções orais um tratamento didático-pedagógico à altura do papel que esses fenômenos desempenham, tanto no uso pragmático da língua como no campo literário. As reflexões são elaboradas a partir de uma concepção que assume a língua como instrumento, meio de interação e constituição de subjetividades; adotam o conceito de gêneros do discurso de Bakthin e constroem sua coerência contextual tendo como base a práxis pedagógica do autor em cursos de formação de professores (iniciais e em serviço.

Full Text Available Numerosas investigaciones aseguran que la inclusión de canciones y/o de elementos sonoro-musicales en la enseñanza de lenguas extranjeras (LE aporta beneficios en el proceso de aprendizaje a niveles lingüísticos, afectivos y sociolingüísticos. El objetivo central de este estudio fue el de mostrar los resultados de un programa sonoro-musical puesto en práctica en la enseñanza de inglés como le con escolares españoles de sexto de primaria. Primeramente, se estudió cuantitativamente si el alumnado con habilidades auditivas avanzadas aprendía una LE de forma más efectiva y si éstos mostraban también un alto nivel de desarrollo de la inteligencia musical. Seguidamente, se puso en marcha la intervención sonoro-musical para comprobar si aquellos estudiantes con un bajo nivel de inteligencia musical podrían mejorar su capacidad auditiva y su competencia comunicativa. Los resultados apuntan que este programa no solo incrementa la comprensión oral, sino la producción oral, la lectora y la motivación del alumnado.

Full Text Available This article makes a case in defense of oral history in the study of political science and international relations. The existing literature has scrutinized the technical aspects and appropriate use of oral material. This article focuses on the circumstances under which oral history may be an indispensable method of scholarly investigation: first, when written primary sources are not readily available; second, when an investigation targets complex and secret high-level negotiations; and third, when the main research concern is the human agent’s perspective and ideational factors. The article first addresses the issue of reliability and rigor of oral history as compared to written sources and then concentrates on the creation of Mercosur as an example of the validity of oral history under the three circumstances identified. The conclusion proposes a revival of a more historical approach to political studies.Este artículo argumenta en favor del uso de la historia oral como método de estudio de las relaciones internacionales y de las ciencias políticas. La literatura académica se ha centrado en las cuestiones más técnicas de las entrevistas y en el uso apropiado de este método. El foco innovador del articulo analiza las circunstancias en que la historia oral puede representar una herramienta indispensable para la investigación académica: primero, cuando las fuentes escritas no están disponibles; segundo, cuando se investigan negociaciones reservadas y complejas de alto nivel; tercero, cuando el interés principal de la investigación es la perspectiva del agente y los factores ideacionales. En primer lugar, el artículo discute la confiabilidad y el rigor de la historia oral en comparación con las fuentes escritas. Luego, el análisis se centra en el caso de estudio de la creación de Mercosur, usado como ejemplo de la validez de la historia oral bajo las tres circunstancias identificadas.

Possuem seis genes que se expressam precocemente e dois genes que se expressam tardiamente, sendo denominados respectivamente E (early e L (late. O ácido desoxirribonucleico (DNA viral dentro da célula do hospedeiro pode assumir duas formas: epissomal e integrada. O HPV tem como alvo as células basais de epitélios escamosos, em particular da área genital, onde está associado ao carcinoma da cérvice uterina. Na boca, o HPV está associado a papiloma escamoso oral, condiloma acuminado, verruga vulgar e hiperplasia epitelial focal. Entretanto, seu papel na carcinogênese oral é ainda controverso, sendo também identificado como agente etiológico de alguns carcinomas de células escamosas de cabeça e pescoço. A infecção pelo HPV pode agir sinergicamente com agentes carcinogênicos, como o tabaco e o álcool. Pelo menos 150 subtipos diferentes de HPV já foram identificados, sendo que 25 têm sido detectados em lesões orais. Considerando a relevância do tema para a melhor compreensão da infecção oral pelo HPV, o objetivo desta atualização é rever os aspectos relevantes da biologia do HPV, com ênfase na relação HPV-ceratinócitos, e a importância dos dados clínicos e histopatológicos na definição diagnóstica das lesões orais possivelmente associadas ao HPV.Papillomaviruses belong to the family Papillomaviridae and their life cycle is directly linked to the differentiation of host epithelial cells.

Full Text Available La poesía de Gabriela Mistral conserva numerosos rastros del lenguaje oral y parece exigir para su "performance'" la lectura comunitaria y no la de la soledad de texto y lector. En el presente trabajo se ha denominado "oralidad residual" a este fenómeno, y se intenta, como primer paso de una investigación más amplia, determinar las causas de dicho fenómeno. The poetry of Gabriela Mistral retains many traces of oral language and seems to require conmunal reading for its "performance" and not the loneliness of text and reader.

Na primeira, além de apresentarmos nossa perspectiva conceitual sobre HP, refletimos sobre a historicidade da noção de HP na Inglaterra, nos Estados Unidos e no Brasil, pontuando seus diversos cruzamentos com a HO. Em seguida, com base numa ampla pesquisa documental, perscrutamos os sentidos de História Oral e o papel atribuído ao historiador e ao conhecimento histórico durante a criação do Laboratório de História Oral da Universidade da Região de Joinville (LHO/Univille. Nesse fazer, analisamos como, no início dos anos 1980, esse espaço foi concebido como parte de uma rede de produção de fontes orais que envolvia numerosas instituições de ensino superior do sul do Brasil e, também, entidades internacionais de atuação multilateral, tais como a Organização dos Estados Americanos (OEA e a Secretaria de Cooperação Técnica Internacional do Brasil, subordinada ao então Ministério de Educação e Cultura (SUBIN/MEC. No terceiro e último item, finalizamos o texto tecendo algumas considerações sobre os limites e as possibilidades reflexivas da HP quando articulada à HO e aos recentes debates sobre o papel público do historiador na escrita da História do Tempo Presente.   Palavras-chave: História Pública; História Oral; História do Tempo Presente; LHO/Univille.

Full Text Available RACIONAL: Embora a dinâmica da deglutição ocorra de forma integrada, a fase oral não tem sido tão valorizada quanto a fase faríngea. OBJETIVOS: Avaliar, através do método videofluoroscópico, a fase oral da deglutição, para observar as características da organização do bolo líquido em voluntários sadios e as variações desta organização em exames de pacientes disfágicos. Estabelecer a inter-relação funcional dos estágios de organização e ejeção oral do bolo. Verificar a presença (ou ausência de interferência do binômio organização/ejeção oral, sobre a fase faríngea da deglutição. CASUÍSTICA E MÉTODO: Analisaram-se os exames videofluoroscópicos de 44 indivíduos; destes, 14 eram adultos, voluntários sadios, e 30 disfágicos, sendo 15 pacientes com seqüelas de acidente vascular encefálico e 15 com doença de Parkinson. Todos os indivíduos estudados foram submetidos a avaliação videofluoroscópica da dinâmica da deglutição seguindo protocolo descrito por Junqueira e Costa. Privilegiou-se a incidência em perfil direito com meio de contraste líquido (solução de sulfato de bário. RESULTADOS: Segundo a organização intra-oral do bolo contrastado, pôde-se classificar a organização oral como: fechada, aberta, que pode ser subdividida em anterior e ântero-superior, alongada e instável. A ejeção pode ser definida como: adequada, lentificada e em dois tempos. A correlação entre a dinâmica oral representada pela organiza��ão e a dinâmica faríngea pode ser percebida como: adequada, adaptada e alterada. Os diversos tipos de organização e ejeção, assim como as correlações observadas, mostram-se estatisticamente significantes. CONCLUSÕES: A organização do tipo fechada é a que se caracterizou como normal. Organizações aberta ântero-superior, alongada e instável revelam alteração no processo da deglutição. As ejeções dos tipos lentificada e dois tempos também denotam

Após a inclusão em parafina, os cortes corados com H&E, foram selecionadas 30 biópsias e separadas em 3 grupos: lesões sem displasia (n=10, lesões com diferentes graus de displasia (n=10 e carcinoma espinocelular invasivo(n=10. As lesões que apresentaram displasia epitelial foram classificadas de acordo com os critérios histopatológicos propostos por Van Der Waal. As lesões foram investigadas para a presença de HPV por hibridização in situ com sondas biotiniladas de amplo espectro, 6/11 e 16/18. HPV 16/18 foi detectado em 20% (n=2 das biópsias com displasia severa. A presença de HPV 16/18 em lesões malignas sugere sua importância como fator de risco na carcinogênese oral.The purpose of this study was to investigate the prevalence of human papillomavirus 6/11 and 16/18 in patients, with oral lesions clinically diagnosed as leucoplakia, attending the School of Dentistry, University of São Paulo State/UNESP, Brazil. After paraffin embedded process, in the sections staining with H&E, 30 biopsies were screened and separated on 3 groups: 10 oral lesions without dysplasia, 10 with dysplasia, and 10 with invasive squamous cell carcinoma. The lesions with dysplasia were classified in agreement with Van Der Wall's histopathological standard method. Oral lesions were investigated for the presence of human papillomavirus (HPV by in situ hybridization with wide-spectrum, 6/11 and 16/18 biotinylated probes. HPV 16/18 was found in 20% (n=2 of the leucoplakia with severe-degree dysplasia. The presence of HPV 16/18 in malignant lesions suggests its importance as a risk factor for oral carcinogenesis.

Full Text Available FUNDAMENTO: O tratamento mais utilizado para pacientes com dermatoses bolhosas crônicas é a corticoterapia oral, muitas vezes em altas doses e por períodos prolongados. Como efeitos colaterais dessa terapêutica, freqüentemente ocorrem: hipertensão arterial, diabete, osteoporose, infecções e distúrbios hidroeletrolíticos. A catarata subcapsular posterior é raramente citada na literatura como efeito colateral da corticoterapia em pacientes com doenças bolhosas. OBJETIVO: Avaliar a prevalência de catarata subcapsular posterior como efeito colateral da corticoterapia oral. MÉTODOS: Trata-se de um estudo retrospectivo incluindo 49 pacientes com dermatoses bolhosas crônicas em uso de corticoterapia acompanhados entre janeiro de 1987 e dezembro de 1997 no ambulatório de Dermatoses Bolhosas do Departamento de Dermatologia da Unifesp/EPM e regularmente submetidos à avaliação oftalmológica em busca de catarata cortisônica. RESULTADOS: No período de 1987 a 1997, 49 pacientes foram avaliados, tendo apresentado prevalência de catarata subcapsular posterior como efeito colateral da corticoterapia oral de 28,57%. CONCLUSÕES: 1 a prevalência de catarata foi de 28,57%; 2 o tempo médio de tratamento até o surgimento de catarata foi de 45,71 meses; 3 a média da dose máxima de corticosteróide utilizada pelos pacientes foi de 78,57mg/dia.BACKGROUND: Oral corticosteroid is the treatment most used for patients with chronic bullous dermatosis, often at high dosages and over long periods of time. Arterial hypertension, diabetes, osteoporosis, infections and hydro-electrolytic disturbances frequently occur as side effects of this therapy. Posterior subcapsular cataract is rarely mentioned in the literature as a side effect of corticosteroid in patients with bullous diseases.

En la implementación de la cátedra, organizada en áreas de desarrollo: "Historia de la Universidad de Ciencias Médicas"; "La narrativa oral y la relación interdisciplinaria"; "La medicina narrativa"; "La narración oral como arte y conducta ex-presivo-comunicativa", la transversali-dad del enfoque de género aparece como una estrategia metodológica que desde un planteamiento sistémico vislumbra todo el proceso educativo que posibilita el desarrollo de las habilidades básicas del pensamiento y comunicación basadas en la narración oral. En las conclusiones se expresa cómo el logro de estos objetivos ha transcurrido por un conjunto de actividades en las esferas de la docencia, investigación y extensión, donde además de abordar los aspectos teóricos, se ha realizado una reflexión compartida como construcción y experiencia sociocultural que permitió un intercambio de saberes, experiencias y participación a través de la narración oral, la cual se ha proyectado como espacio abierto para el aprendizaje, experiencia esencialmente humana y estrategia para la investigación.

A pesquisa foi realizada em três escolas públicas da cidade de Araçatuba, Estado de São Paulo, com dez alunos em cada uma delas. Para a realização dos grupos focais foram abordadas as seguintes palavras, presentes em perguntas de questionários sobre saúde bucal, as quais apresentaram altos índices de erros: saúde bucal; placa bacteriana; dente permanente; flúor; gengiva sangra?; fio dental; transmissão da cárie. Durante as discussões dos grupos focais, observou-se que muitos adolescentes ficavam surpresos com a situação a qual foram submetidos e com o tema que estavam discutindo. A palavra ‘saúde bucal’ foi associada à condição de limpeza dacavidade bucal, não identificando a saúde bucal como parte da saúde geral. O termo ‘transmissão da cárie’ não teve um entendimento suficiente. A expressão ‘dente permanente’ foi bem compreendida, sendo associada a um tipo de dente que não seria mais substituído.A palavra ‘flúor’ teve maior associação à função de limpeza do que à proteção dos dentes. Conclui-se que a utilização da técnica do Grupo Focal é de grande importância na interpretação do conhecimento dos adolescentes sobre saúde bucal e na adequação da terminologia de questionários sobre o mesmo tema.This study aims to the understanding of adolescents regarding oral health, using the Focus Group technique.

Full Text Available Growing evidence suggests a role for human papillomavirus (HPV in oral cancer; however its involvement is still controversial. This study evaluates the frequency of HPV DNA in a variety of oral lesions in patients from Argentina. A total of 77 oral tissue samples from 66 patients were selected (cases; the clinical-histopathological diagnoses corresponded to: 11 HPV- associated benign lesions, 8 non-HPV associated benign lesions, 33 premalignant lesions and 25 cancers. Sixty exfoliated cell samples from normal oral mucosa were used as controls. HPV detection and typing were performed by polymerase chain reaction (PCR using primers MY09, 11, combined with RFLP or alternatively PCR using primers GP5+, 6+ combined with dot blot hybridization. HPV was detected in 91.0% of HPV- associated benign lesions, 14.3% of non-HPV associated benign lesions, 51.5% of preneoplasias and 60.0% of cancers. No control sample tested HPV positive. In benign HPV- associated lesions, 30.0% of HPV positive samples harbored high-risk types, while in preneoplastic lesions the value rose to 59.9%. In cancer lesions, HPV detection in verrucous carcinoma was 88.9% and in squamous cell carcinoma 43.8%, with high-risk type rates of 75.5% and 85.6%, respectively. The high HPV frequency detected in preneoplastic and neoplastic lesions supports an HPV etiological role in at least a subset of oral cancers.Crecientes evidencias sugieren que el virus Papiloma humano (HPV tiene un rol en el cáncer oral; sin embargo su participación es todavía controvertida.

Foram avaliados 62 hospitais da rede pública e privada. Quando questionados se existia na instituição algum procedimento destinado aos pacientes internados (no caso de UTIs, 39% dos hospitais pesquisados responderam positivamente. Das instituições pesquisadas, apenas 15% possuem um protocolo regular para o controle de placa nos pacientes internados. Pesquisas têm demonstrado a inter-relação da doença periodontal com doenças sistêmicas, como doenças cardiovasculares, osteoporose, nascimento de bebês de baixo peso e parto prematuro, diabetes e doenças respiratórias. A cavidade oral tem sido considerada como um potente reservatório de patógenos respiratórios. Diante destes fatos, evidencia-se a importância da higiene bucal como um meio de se prevenir patologias diversas. Desta forma, existe a necessidade de se criar um protocolo de controle de infecção da cavidade oral para contribuir para a redução da mortalidade de pacientes internados e propor medidas preventivas para este fim.The aim of the present study is to ascertain whether an oral infection control protocol is being used in Rio de Janeiro State hospitals. Sixty two hospitals, both public and private have been surveyed. When asked whether any procedure was being adopted with admitted patients (in case of ICU patients, 39% of the hospitals responded positively. Among all institutions surveyed, only 15% conduct a regular plaque control protocol in admitted patients. Studies have shown that there is an inter-relationship between periodontal disease and systemic diseases, such as cardiovascular disease, osteoporosis, preterm births and low birthweight, diabetes and respiratory diseases. The oral cavity is considered a potent reservoir of respiratory pathogens. Based on these findings, it has become evident that oral hygiene is

Oral sex, oral health and orogenital infections

Full Text Available Oral sex is commonly practiced by sexually active male-female and same-gender couples of various ages, including adolescents. The various type of oral sex practices are fellatio, cunnilingus and analingus. Oral sex is infrequently examined in research on adolescents; oral sex can transmit oral, respiratory, and genital pathogens. Oral health has a direct impact on the transmission of infection; a cut in your mouth, bleeding gums, lip sores or broken skin increases chances of infection. Although oral sex is considered a low risk activity, it is important to use protection and safer sex precautions. There are various methods of preventing infection during oral sex such as physical barriers, health and medical issues, ethical issues and oral hygiene and dental issues. The lesions or unhealthy periodontal status of oral cavity accelerates the phenomenon of transmission of infections into the circulation. Thus consequences of unhealthy or painful oral cavity are significant and oral health should be given paramount importance for the practice of oral sex.

Full Text Available El presente ensayo subraya la importancia del análisis y contextualización de los recuerdos vertidos en una entrevista de historia oral, señalando que esta es una de las características que distinguen la historia oral de otras maneras de trabajar con la memoria. El historiador oral lleva a cabo el examen crítico de la fuente, como lo hace con fuentes documentales escritas, prestando atención a las particularidades de la memoria y la oralidad que definen la fuente, y la peculiaridad de la entrevista que produce la fuente. El ensayo propone que para llevar a cabo el análisis es necesario observar cómo la narración de recuerdos maneja el tiempo y el espacio, cómo el narrador presenta su yo y las redes sociales en las que se desenvuelve, y cómo la narración privilegia el relato de anécdotas para desplegar símbolos y significados que dan coherencia a lo vivido. Esta es una primera parte de análisis, con el fin de comprender el sentido cabal del documento integro que es la entrevista. La segunda parte consiste en situar la entrevista y el relato en contexto, tanto el contexto histórico de lo relatado como el contexto del tiempo y las condiciones de producción de lo que es en realidad una conversación histórica. Ello nos permite entender la entrevista como un documento cultural de su época.

Full Text Available O objetivo desta revisão da literatura é discutir a importância da educação em saúde como estratégia de promoção de saúde bucal no período gestacional. Foram estudadas as manifestações bucais mais comuns na gestação, concluindo-se que, embora a gestação por si só não seja responsável por tais manifestações como, por exemplo, a cárie dentária e a doença periodontal, faz-se necessário o acompanhamento odontológico no pré-natal, considerando-se que as alterações hormonais da gravidez poderão agravar as afecções já instaladas. Destacou-se na promoção de saúde bucal na gestante a educação em saúde bucal, considerando-a parte importante do Programa de Atenção à Saúde da Mulher, conforme recomendado pelas atuais Diretrizes da Política Nacional de Saúde Bucal. Considera-se que, por meio de ações de educação em saúde bucal, desenvolvidas no pré-natal por uma equipe multiprofissional, orientada por um cirurgião-dentista, a mulher poderá se conscientizar da importância de seu papel na aquisição e manutenção de hábitos positivos de saúde bucal no meio familiar e atuar como agente multiplicador de informações preventivas e de promoção de saúde bucal.This literature revision is intended to discuss the importance of health education as a strategy to oral health promotion in the pregnancy period. The most common mouth manifestations during pregnancy have been studied, and the conclusion is that, although pregnancy itself is not responsible for such manifestations in the mouth, e.g. dental decay and periodontal diseases, a dentistry follow-up during prenatal care is necessary, considering that hormonal alterations in pregnancy may aggravate the diseases contracted. The oral health promotion for pregnant women has been focused on mouth health education, considering it an important part of the Program of Attention to Women's Health, as recommended by the current National Politics' Mouth Health

Son elásticos no indurados, depresibles y frágiles, con crecimiento lentamente progresivo . MATERIAL Y MÉTODOS:Presentamos dos casos . Varón afecto de hematemesis repetidas sin identificarse origen inicialmente, demostrándose tumor de Masson de paladar duro oculto por prótesis dental, que fue resecado mediante pinza bipolar previa infiltración con suero perilesional para devascularizarlo. El segundo fue una mujer  que en relación con la ingesta presentó cuadro de hematemesis importante. La valoración de Urgencias y la endoscopia digestiva no identificaron el origen del sangrado en tubo digestivo, aunque la endoscopista identificó nuevo sangrado desde cavidad oral. La exploración ORL objetivó una pequeña tumoración rojiza de apariencia vascular en zona de mordida izquierda, sangrante al mínimo roce, cuya resección se realizó de urgencia sin incidencias, con idéntica técnica y diagnóstico anatomopatológico. Posteriormente, se constató el antecedente de episodios previos de menor cuantía. DISCUSIÓN: Los tumores de Masson son muy raros en tubo digestivo y excepcionales en cavidad oral. Se han relacionado con irritaciones repetidas o traumatismos locales,hematomas encapsulados o preexistencia de otras lesiones vasculares. Estos factores parecen haber acontecido en nuestros pacientes (roce de prótesis dental en paladar y mordidas de repetición. Son masas de lento crecimiento en las que se producen con frecuencia fenómenos trombóticos. Sin embargo, el roce de su superficie puede dar lugar a sangrados importantes como en estos casos.

La hidratación oral es uno de los descubrimientos médicos más importantes del siglo veinte; su base fisiológica es el transporte acoplado de sodio y otros solutos, que favorece el ingreso de agua a las células del intestino. El suero de hidratación oral (SHO con la fórmula recomendada por la Organización Mundial de la Salud (OMS, utiliza como so luto transportador la glucosa. Su osmolaridad es ligeramente mayor que la de los líquidos corporales: 311 mOsm/L.

ORT solution with the composition recommended by the World Health Organization, is one of the most important medical advances of the present century; it has, however, some drawbacks that may partly explain why it is used with a lower frequency than it is desirable. In order to overcome such limitations other substances have been tried for the preparation of OR solutions; the ideal preparation should both hydrate and prevent further dehydration, decrease the volume of stools and the duration of diarrhea and provide some nutrients. The following substances have been tried for the preparation of oral solution: glycine, glutamine, alanine, rice and other cereals, maltodextrines, protein hydrolysates and low osmolarity solutions; in light of the results obtained so far, these products offer no advantage over the standard solution.

En dicho corpus, figuran narraciones que pertenecen a la tradición oral andina, cuya inclusión demuestra la firme identificación del autor con el relato popular, así como el papel decisivo que este desempeña en el contenido y estructura de su novelística. En esa misma dirección, se halla la figura del narrador oral, cuya perfomance y estrategias discursivas siguen el modelo del narrador popular. Por otro lado, en la novelística alegriana, la tradición oral se articula con la memoria colectiva y expresa la visión de los indios mediante narraciones testimoniales. En un plano mayor, la filiación de la novelística alegriana con la literatura oral representa una valoración de las expresiones de la literatura no canónica en el Perú.

Full Text Available Antecedentes. Diferentes estudios relacionan las dificultades del lenguaje oral con las dificultades de lectura. La mayoría de estas investigaciones se han realizado en lenguas con ortografías opacas como el inglés y sus resultados no pueden ser completamente generalizables al español. Objetivo. Describir la relación entre las dificultades del lenguaje oral y la adquisición de lectura en el español como lengua de ortografía transparente, en una muestra de niños escolarizados. Material y métodos. Participaron 58 niños en dos momentos diferentes, una evaluación inicial, realizada entre los cinco y seis años de edad y otra final realizada tres años después. La evaluación inicial del lenguaje oral se realizó mediante la aplicación de la prueba Preeschool Language Scale (PSL-3 y en un segundo tiempo se evaluó la lectura utilizando la prueba Evaluación de los Procesos Lectores PROLEC. Resultados. Se observó una relación entre la evaluación del lenguaje oral (comprensión auditiva y comunicación expresiva y la lectura (decodificación y comprensión. La lectura de los niños identificados con retraso de lenguaje presenta diferencias clínica y estadísticamente significativas con respecto a los niños sin retraso, especialmente en el proceso de decodificación. Se observa igualmente un ritmo evolutivo diferente entre los dos grupos coincidiendo con la hipótesis de la recuperación ilusoria. Conclusiones. Los resultados de este estudio sugieren que las dificultades del lenguaje oral en español repercuten tanto en los procesos de decodificación como en los de comprensión. La relevancia de este estudio, radica en que se aproxima a la relación entre los componentes del lenguaje oral y la lectura, favoreciendo los procesos de promoción, prevención, diagnóstico e intervención fonoaudiológica en contextos tanto clínicos como educativos.

It is associated with poor oral hygiene, alcoholism, senility, suppurating lesions, severe halitosis. It is seen frequently in tropical countries and hot climatic regions. The reported cases in literature of oral Myiasis associated with oral cancer are few. The treatment is a mechanical removal of the maggots but a systemic treatment with Ivermectin, a semi - synthetic macrolide antibiotic, has been used successfully for treatment for oral m yiasis. We present a case of 55 yr old male alcoholic patient with oral myiasis with extensive proliferative growth of oral cavity. Our patient was managed with manual debridement and administration of systemic ivermect in along with antibiotic coverage. Incisional biopsy of the proliferative lesion showed well differentiated squamous cell carcinoma. Thus our patient showed presence of oral myiasis in association with oral squamous cell carcinoma.

Oral human papillomavirus (HPV) infection is the cause of 40% to 80% of oropharyngeal cancers; yet, no published study has examined the role of oral health in oral HPV infection, either independently or in conjunction with other risk factors. This study examined the relation between oral health and oral HPV infection and the interactive effects of oral health, smoking, and oral sex on oral HPV infection. Our analyses comprised 3,439 participants ages 30 to 69 years for whom data on oral HPV and oral health were available from the nationally representative 2009-2010 National Health and Nutrition Examination Survey. Results showed that higher unadjusted prevalence of oral HPV infection was associated with four measures of oral health, including self-rated oral health as poor-to-fair [prevalence ratio (PR) = 1.56; 95% confidence interval (CI), 1.25-1.95], indicated the possibility of gum disease (PR = 1.51; 95% CI, 1.13-2.01), reported use of mouthwash to treat dental problems in the past week (PR = 1.28; 95% CI, 1.07-1.52), and higher number of teeth lost (Ptrend = 0.035). In multivariable logistic regression models, oral HPV infection had a statistically significant association with self-rated overall oral health (OR = 1.55; 95% CI, 1.15-2.09), independent of smoking and oral sex. In conclusion, poor oral health was an independent risk factor of oral HPV infection, irrespective of smoking and oral sex practices. Public health interventions may aim to promote oral hygiene and oral health as an additional measure to prevent HPV-related oral cancers.

Full Text Available The worldwide incidence of head and neck cancer is, approximately, 640,000 new cases per year. Oral cancer accounts for one third of all cancers and it is the eighth most diagnosed in men. The most used treatments for these tumors are surgery, radiotherapy, chemotherapy, or a combination of these therapeutic modalities. Due to the large structural, functional and aesthetic impairment that conventional treatments cause, many studies seek new methods to replace or to assist the treatment of oral cancer. Photodynamic therapy (PDT is a promising new modality of cancer treatment that is already being used clinically. This article describes the use of PDT as an alternative for the treatment of oral cancer.

Oral diseases are known to be closely associated with oral biofilm metabolism, while cancer tissue is reported to possess specific metabolism such as the 'Warburg effect'. Metabolomics might be a useful method for clarifying the whole metabolic systems that operate in oral biofilm and oral cancer, however, technical limitations have hampered such research. Fortunately, metabolomics techniques have developed rapidly in the past decade, which has helped to solve these difficulties. In vivo metabolomic analyses of the oral biofilm have produced various findings. Some of these findings agreed with the in vitro results obtained in conventional metabolic studies using representative oral bacteria, while others differed markedly from them. Metabolomic analyses of oral cancer tissue not only revealed differences between metabolomic profiles of cancer and normal tissue, but have also suggested a specific metabolic system operates in oral cancer tissue. Saliva contains a variety of metabolites, some of which might be associated with oral or systemic disease; therefore, metabolomics analysis of saliva could be useful for identifying disease-specific biomarkers. Metabolomic analyses of the oral biofilm, oral cancer, and saliva could contribute to the development of accurate diagnostic, techniques, safe and effective treatments, and preventive strategies for oral and systemic diseases.

Full Text Available This study aimed at evaluating the effect of different concentrations of hydrolyzed collagen (HC on the properties of an orally disintegrating film containing propolis ethanol extract (PEE as an active component. The films were evaluated in terms of total phenols, mechanical properties, solubility, contact angle, disintegration time, and microstructure. The films were prepared by casting with 2 g of protein mass (gelatin and HC, 30 g of sorbitol/100 g of protein mass, and 100 g of PEE/100 g of protein mass. HC was incorporated at concentrations of 0, 10, 20, and 30 g/100 g of protein mass. It was found that increased concentrations of HC reduced tensile strength and increased elongation; however, all films showed plastic behavior. An increase in solubility at 25 ºC, a reduction in the contact angle, and disintegration time were also observed. Thus, higher concentrations of collagen led to more hydrophilic and more soluble polymeric matrices that showed shorter dissolution time, favoring the use of these materials as carriers for active compounds to be delivered in the oral cavity.Este trabalho teve como objetivo avaliar o efeito de diferentes concentrações de colágeno hidrolisado nas propriedades de filmes de desintegração oral contendo extrato etanólico de própolis como componente ativo.

Hernandez, Brenda Y; Zhu, Xuemei; Goodman, Marc T; Gatewood, Robert; Mendiola, Paul; Quinata, Katrina; Paulino, Yvette C

Oral cancers are attributed to a number of causal agents including tobacco, alcohol, human papillomavirus (HPV), and areca (betel) nut. Although betel nut chewing has been established as an independent cause of oral cancer, the mechanisms of carcinogenesis are poorly understood. An investigation was undertaken to evaluate the influence of betel nut chewing on the oral microbiome and oral premalignant lesions. Study participants were recruited from a dental clinic in Guam. Structured interviews and oral examinations were performed. Oral swabbing and saliva samples were evaluated by 454 pyrosequencing of the V3- V5 region of the 16S rRNA bacterial gene and genotyped for HPV. One hundred twenty-two adults were enrolled including 64 current betel nut chewers, 37 former chewers, and 21 with no history of betel nut use. Oral premalignant lesions, including leukoplakia and submucous fibrosis, were observed in 10 chewers. Within-sample bacterial diversity was significantly lower in long-term (≥10 years) chewers vs. never chewers and in current chewers with oral lesions vs. individuals without lesions. Between-sample bacterial diversity based on Unifrac distances significantly differed by chewing status and oral lesion status. Current chewers had significantly elevated levels of Streptococcus infantis and higher and lower levels of distinct taxa of the Actinomyces and Streptococcus genera. Long-term chewers had reduced levels of Parascardovia and Streptococcus. Chewers with oral lesions had significantly elevated levels of Oribacterium, Actinomyces, and Streptococcus, including Streptococcus anginosus. In multivariate analyses, controlling for smoking, oral HPV, S.anginosus, and S. infantis levels, current betel nut chewing remained the only predictor of oral premalignant lesions. Our study provides evidence that betel nut chewing alters the oral bacterial microbiome including that of chewers who develop oral premalignant lesions. Nonetheless, whether microbial changes

Full Text Available Many oral lesions may need to be diagnosed by removing a sample of tissue from the oral cavity. Biopsy is widely used in the medical field, but the practice is not quite widespread in dental practice. As oral pathologists, we have found many artifacts in the tissue specimen because of poor biopsy technique or handling, which has led to diagnostic pitfalls and misery to both the patient and the clinician. This article aims at alerting the clinicians about the clinical faults arising preoperatively, intraoperatively and postoperatively while dealing with oral biopsy that may affect the histological assessment of the tissue and, therefore, the diagnosis. It also reviews the different techniques, precautions and special considerations necessary for specific lesions.

To evaluate oral cancer-related screening practices of Oral Health Professionals (OHPs - dentists, dental hygienists, dental therapists, and oral health therapists) practising in Victoria, Australia. A 36-item survey was distributed to 3343 OHPs. Items included socio-demographic and work-related characteristics; self-assessed knowledge of oral cancer; perceived level of confidence in discussing oral health behaviors with patients; oral cancer screening practices; and self-evaluated need for additional training on screening procedures for oral cancer. A total of 380 OHPs responded this survey, achieving an overall response rate of 9.4%. Forty-five were excluded from further analysis. Of these 335 OHP, 72% were dentists; (n = 241); either GDP or Dental Specialists; 13.7% (n = 46) were dental hygienists; 12.2% (n = 41) were oral health therapists, and the remaining 2.1% (n = 7) were dental therapists. While the majority (95.2%) agreed that oral cancer screening should be routinely performed, in actual practice around half (51.4%) screened all their patients. Another 12.8% "Very rarely" conducted screening examinations. The probability of routinely conducting an oral cancer screening was explored utilising Logistic Regression Analysis. Four variables remained statistically significant (p oral cancer screening rose with increasing levels of OHPs' confidence in oral cancer-related knowledge (OR = 1.35; 95% CI: 1.09-1.67) and with higher levels of confidence in discussing oral hygiene practices with patients (OR = 1.25; 95% CI: 1.03-1.52). Results also showed that dental specialists were less likely to perform oral cancer screening examinations compared with other OHPs (OR = 0.18; 95% CI: 0.07-0.52) and the likelihood of performing an oral cancer screening decreased when the "patient complained of a problem" (OR = 0.21; 95% CI: 0.10-0.44). Only half the study sample performed oral cancer screening examinations for all of their patients

The aim of this study is to determine relationship between oral hygiene and colonisation of Candia species in oral cavity. Maintenance oral hygiene is reducing pathological agents in the mouth and preventing violation of oral health. Study included 140 patients. For oral hygiene assessement were used the dental plaque index, oral hygiene index and dental calculus index. Ph test strips were used to determine pH of saliva. For isolation of Candida species oral swabs were taken to all patients. It was found out that pH of oral cavity does not varies notably, no matter of oral hygiene level. Candida species were identified in 28.6% respondents. The most present were Candida albicans, in 85% cases. The presence of plaque, tartar and high index oral hygiene (IOH) in patients with Candida is statistically significant. It was found that 83.4% of patients with Candida poorly maintained oral hygiene. Poor oral hygiene is associated with a significantly higher score in the presence of tartar, plaque and high IOH. In total patient's population 67% has amalgam fillings. Presence of amalgam fillings in patients with identified Candida was statistically significant. This study indicates low level of oral hygiene. Correlation between presence of Candida species and poor oral hygiene was proved. Also Candida was more present among patients with amalgam fillings. Improvement of oral hygiene is necessery for oral health and health in general, as well.

Effect of Fixed Metallic Oral Appliances on Oral Health.

Alnazzawi, Ahmad

2018-01-01

There is a substantial proportion of the population using fixed metallic oral appliances, such as crowns and bridges, which are composed of various dental alloys. These restorations may be associated with a number of effects on oral health with variable degrees of severity, to review potential effects of using fixed metallic oral appliances, fabricated from various alloys. The MEDLINE/PubMed database was searched using certain combinations of keywords related to the topic. The search revealed that burning mouth syndrome, oral pigmentation, hypersensitivity and lichenoid reactions, and genotoxic and cytotoxic effects are the major potential oral health changes associated with fixed prosthodontic appliances. Certain oral disorders are associated with the use of fixed metallic oral appliances. Patch test is the most reliable method that can be applied for identifying metal allergy, and the simultaneous use of different alloys in the mouth is discouraged.

[Oral microbiota: a promising predictor of human oral and systemic diseases].

Science.gov (United States)

Xin, Xu; Junzhi, He; Xuedong, Zhou

2015-12-01

A human oral microbiota is the ecological community of commensal, symbiotic, and pathogenic microorganisms found in human oral cavity. Oral microbiota exists mostly in the form of a biofilm and maintains a dynamic ecological equilibrium with the host body. However, the disturbance of this ecological balance inevitably causes oral infectious diseases, such as dental caries, apical periodontitis, periodontal diseases, pericoronitis, and craniofacial bone osteomyelitis. Oral microbiota is also correlated with many systemic diseases, including cancer, diabetes mellitus, rheumatoid arthritis, cardiovascular diseases, and preterm birth. Hence, oral microbiota has been considered as a potential biomarker of human diseases. The "Human Microbiome Project" and other metagenomic projects worldwide have advanced our knowledge of the human oral microbiota. The integration of these metadata has been the frontier of oral microbiology to improve clinical translation. By reviewing recent progress on studies involving oral microbiota-related oral and systemic diseases, we aimed to propose the essential role of oral microbiota in the prediction of the onset, progression, and prognosis of oral and systemic diseases. An oral microbiota-based prediction model helps develop a new paradigm of personalized medicine and benefits the human health in the post-metagenomics era.

The oral cavity is inhibited by many of the bacterial species. Some of them have a key role in the development of oral disease. Interrelationships between oral microbiome and systemic conditions such as head-and-neck cancer have become increasingly appreciated in recent years. Emerging evidence also suggests a link between periodontal disease and oral cancer, and the explanation being that chronic inflammation could be a major factor in both diseases. Squamous cell carcinoma is that the most frequently occurring malignancy of the oral cavity and adjacent sites, representing over 90% of all cancers. The incidence of oral cancer is increasing, significantly among young people and women. Worldwide there are 350,000-400,000 new cases diagnosed every year. Bacteria, viruses, and fungi are strongly implicated as etiological factors in certain cancers. In this review we will discuss the association between the development of oral cancer in potentially malignant oral lesions with chronic periodontitis, chronic Porphyromonas gingivalis, Fusobacterium nucleatum, candida, other microbes and described mechanisms which may be involved in these carcinoma.

Strengthening of Oral Health Systems: Oral Health through Primary Health Care

Science.gov (United States)

Petersen, Poul Erik

2014-01-01

Around the globe many people are suffering from oral pain and other problems of the mouth or teeth. This public health problem is growing rapidly in developing countries where oral health services are limited. Significant proportions of people are underserved; insufficient oral health care is either due to low availability and accessibility of oral health care or because oral health care is costly. In all countries, the poor and disadvantaged population groups are heavily affected by a high burden of oral disease compared to well-off people. Promotion of oral health and prevention of oral diseases must be provided through financially fair primary health care and public health intervention. Integrated approaches are the most cost-effective and realistic way to close the gap in oral health between rich and poor. The World Health Organization (WHO) Oral Health Programme will work with the newly established WHO Collaborating Centre, Kuwait University, to strengthen the development of appropriate models for primary oral health care.

2009-08-01

Full Text Available La Úlcera Eosinófila de la Mucosa Oral, es una entidad poco frecuente, pobremente descrita en la literatura mundial. Se define como una lesión benigna autolimitada que si bien puede presentarse en distintas áreas de la cavidad bucal, presenta una marcada predilección por la mucosa ventral de la lengua. Clínicamente, se presenta como una lesión ulcerada de bordes indurados y sobreelevados. Los hallazgos histopatológicos son característicos y consisten en un infiltrado mixto rico en eosinófilos, acompañado de una población de grandes células mononucleadas. Recientes artículos basados en estudios inmunohistoquimicos, permiten afirmar la presencia de grandes linfocitos atípicos CD30+ y por lo tanto, incluir esta lesión en el espectro de las entidades simuladoras de desordenes linfoproliferativos. A pesar de esto, el mecanismo etiopatogenico permanece oscuro y el trauma local juega un rol todavía no dilucidado; aunque se halla presente en la mayoría de las publicaciones, explicando el fenómeno como un mecanismo reactivo. La importancia de esta lesión, radica en su diagnostico diferencial por su semejanza clínica al carcinoma espinocelular, histoplasmosis, chancro sifilítico, Úlcera tuberculosa, carcinoma epidermoide y otras. En nuestro trabajo se revisa la literatura y se discuten la características clínicas, histopatológicas y alternativas terapéuticas, a partir del artículo de un caso clínico en una paciente joven, que luego de la biopsia escisión como método para el diagnostico de certeza, se produce una recidiva de la lesión; lo que orientó el tratamiento hacia la cirugía combinada con corticoterapia local intralesional, logrando su remisión.Eosinophilic Ulcer of the Oral Mucosa, an entity, poorly deciphers in world-wide literature.

Full Text Available Este é um estudo de revisão que sistematiza achados de pesquisas sobre exposições ocupacionais e seus efeitos na saúde bucal, destacando a importância dos dados epidemiológicos no planejamento de programas de saúde bucal do trabalhador. Existem relatos de associação potencial entre exposições ocupacionais e alterações bucais; entretanto, são escassos os estudos sobre as condições de saúde bucal dos trabalhadores em países em desenvolvimento como o Brasil. Entre as exposições ocupacionais presentes na literatura odontológica, observa-se uma predominância de estudos sobre substâncias ácidas e também exposições relacionadas com o açúcar, como a poeira de açúcar. As alterações bucais podem manifestar-se tanto nos tecidos duros (cárie, erosão dental, etc. como nos tecidos moles (lesões da mucosa oral, doenças periodontais, etc. Por outro lado, observa-se que os programas de saúde bucal do trabalhador, quando existem, muitas vezes não consideram as especificidades dessa parcela da população que, além de exposta aos fatores de risco mais conhecidos das principais doenças bucais, está submetida a outros fatores relacionados ao ambiente de trabalho. Assim, considera-se relevante a discussão sobre a necessidade de maior produção de conhecimento nessa área, de capacitação de recursos humanos e de implementação de programas mais efetivos, baseados nos princípios da vigilância em saúde do trabalhador.This study is a review of published research findings in occupational exposures and their impact on oral health, emphasizing the relevance of epidemiological studies in the planning of workers' oral health programs.

Full Text Available El cólera continúa siendo en muchos países un problema para la salud humana, manteniéndose como una enfermedad epidémica o endémica que afecta tanto a niños como adultos y causa la muerte en casos no tratados. Una vacuna viva oral contra esta enfermedad puede ser la solución. En el presente trabajo se seleccionó y aplicó un biomodelo para la evaluación de cepas atenuadas genéticamente de Vibrio cholerae como candidatas vacunales contra el cólera. La virulencia, capacidad de colonización y adherencia a la mucosa intestinal de las cepas fueron evaluadas mediante el uso de ratones neonatos de 2 a 4 días de nacidos de la línea Balb/c, con un peso entre 1,5-2 g. Los resultados obtenidos con este biomodelo demostraron que las cepas atenuadas genéticamente son no virulentas, colonizan y se adhieren a la mucosa intestinal. Se concluye que el biomodelo utilizado permite la evaluación y selección de cepas candidatas para vacunas vivas orales contra el cólera.

Full Text Available Dental plaque is still considered the main etiological factor for periodontal diseases. Our understanding of periodontal disease has advanced from the previous concepts where gingivitis slowly progressed to periodontitis to a more complex scenario that correlates several risk factors in the pathogenesis of periodontal disease. Among these factors, age has been associated with increased rates of periodontal disease as the population gets older. Although the loss of alveolar bone and periodontal attachment is common in the elderly population, and there is evident age-related changes in the periodontium, severe periodontitis is not a natural consequence of ageing. The importance of identifying the risk factors that participate in the pathogenesis of periodontal disease at an early phase, both of the individual and the disease, as well as evaluating the capacity of the individual to control dental plaque will enable the implementation of an adequate preventive program, where the needs and limitations of the individual are considered to specifically tailor the oral hygiene procedures and the mouthwashes to be used.La placa dental es aún considerada el factor etiológico primario de la enfermedad periodontal. La etiopatogenia de esta enfermedad ha avanzado del concepto anterior donde una gingivitis progresaba lentamente a una periodontitis, a un escenario más complejo donde varios factores de riesgo se correlacionan. Dentro estos factores, el envejecimiento ha sido asociado con mayores porcentajes de enfermedad periodontal a medida que la población envejece. Aunque la pérdida ósea y de inserción es común en el adulto mayor y los cambios del periodonto son evidentes con la edad, la enfermedad periodontal severa no es una consecuencia natural del envejecimiento. La importancia de identificar en una etapa temprana del individuo y de la enfermedad los factores de riesgo que participan en la patogenesis de la enfermedad periodontal, así como la

This study aimed to examine the relationships among self-reported oral health, oral hygiene practices, and oral human papillomavirus (HPV) infection in women at risk for sexually transmitted infections (STIs) in Ho Chi Minh City, Vietnam. Convenience and referral sampling methods were used in a clinic-based setting to recruit 126 women aged 18-45 years between August and October 2013. Behavioral factors were self-reported. Oral-rinse samples were tested for HPV DNA of 2 low-risk and 13 high-risk genotypes. A higher unadjusted prevalence of oral HPV infection was associated with poorer self-rated overall oral health (P = .001), reported oral lesions or problems in the past year (P = .001), and reported a tooth loss not because of injury (P = .001). Higher unadjusted prevalence of oral HPV infection was also associated with two measures of oral hygiene: lower frequencies of toothbrushing per day (P = .047) and gargling without toothbrushing (P = .037). After adjusting for other factors in multivariable logistic regression models, poorer self-rated overall oral health remained statistically associated with oral HPV infection (P = .042); yet the frequency of tooth-brushing per day did not (P = .704). Results corroborate the association between self-reported poor oral health and oral HPV infection. The effect of oral hygiene on oral HPV infection remains inconclusive.

Full Text Available Los neurilemomas son tumores neurogénicos benignos, con origen en la vaina neural. De los neurilemomas extracraneales, aproximadamente un 25 a un 45% ocurren en cabeza y cuello. La edad de afectación predominante es entre la tercera y la cuarta décadas de vida. El neurilemoma es un tumor claramente circunscrito y, generalmente, de pequeño tamaño. Clínicamente aparece como una masa de crecimiento lento y gradual. El examen microscópico es necesario para el diagnóstico. El tratamiento de elección es la escisión quirúrgica completa tumoral y después de ésta es muy rara su recurrencia. El propósito de este artículo es presentar un estudio retrospectivo, de nueve casos, de neurilemomas de cavidad oral y cuello, tratados en nuestro servicio de Cirugía Oral y Maxilofacial, entre 1997 y 2001. Hemos valorado una serie de parámetros epidemiológicos (edad, sexo, localización, tamaño, clínica, estudios previos a la cirugía, tiempo trascurrido entre aparición de síntomas y primera consulta, nervio de origen, patrón histológico predominante (Antoni A, Antoni B, y evolución postquirúrgica.

Full Text Available This article examines the presence of discursive and symbolic patterns from Hispanic oral tradition in one of the most significant narratives of the Mexican Revolution, Nellie Campobello’s Cartucho (1931. With a view to offering a subjective, community and regionalist picture of the fights between villistas and carrancistas in the north of Mexico, the author decided to reproduce stories passed on to her by relatives and neighbours, thus creating a deeply polyphonic and testimonial tale. Hence, orality gives shape to a text where the dialogue with literary forms of the Mexican folklore is highly discernible. Particularly relevant is the dialogue maintained by Cartucho with such an outstanding expression of the ballad tradition as the corrido, which is incorporated into the prose through direct quotation, as well as through the reproduction of its typical language and poetics.Este trabajo examina la presencia de estrategias discursivas y representacionales propias de la tradición oral hispánica en uno de los testimonios más sobresalientes del ciclo narrativo de la Revolución Mexicana como es Cartucho (1931, de Nellie Campobello. En su voluntad de ofrecer una visión subjetiva, comunitaria y regionalista de las luchas entre villistas y carrancistas en el norte de México, la autora optó por reproducir historias que le habían sido transmitidas por familiares y vecinos, dando con ello lugar a un relato marcadamente polifónico y testimonial. La voz condiciona así de manera indeleble un texto en el que es perceptible además el diálogo con formas literarias del folclore mexicano, en particular con un representante destacado del género baladístico como el corrido, el cual es convocado en la prosa tanto por medio de la cita directa como por la mímesis de su poética y su lenguaje característicos.

Full Text Available Introducción: el trauma dentoalveolar corresponde a una lesión traumática de alta prevalencia, elevado costo de tratamiento y efectos negativos a nivel funcional, estético y psicológico. Existen factores predisponentes de traumatismo dentoalveolar que coinciden con ciertas características de niños respiradores orales, sin embargo, el rol de la respiración oral como factor predisponente no está claramente determinado. Objetivo: determinar la asociación entre respiración oral y trauma dentoalveolar controlando por otras covariables en niños de 6 a 14 años. Métodos: se aplicó un estudio de casos y controles 1:2. La muestra quedó constituida por 57 casos y 113 controles asumiendo un nivel de confianza del 95 %, una potencia del 80 % y un 10 % de pérdidas. Los casos correspondieron a niños de 6 a 14 años de edad ingresados por TDA a la Unidad de Odontopediatría del Hospital "Dr. Sótero del Río", centro de referencia que atiende a una población de 1 521 144 habitantes de la capital. Los controles correspondieron a niños voluntarios sin TDA del mismo centro asistencial y grupo etario. Los datos fueron recolectados a partir de una entrevista, además de la medición clínica y observación directa para determinar el modo respiratorio. Para diferencias entre grupos se aplicó prueba de Fisher y Mann Whitney. La asociación entre respiración oral y trauma dentoalveolar se evaluó a partir de un modelo logístico considerando sexo, resalte y edad. Resultados: la prevalencia de niños respiradores orales fue mayor en los casos con un 47,4 % (p 0,05 como para ninguna de las covariables del modelo. Conclusiones: respirar a través de la cavidad oral no constituiría un aumento del riesgo de sufrir un trauma dentoalveolar durante un golpe o caída en los niños estudiados.

The purpose of this multicentre study was to determine the incidence of oral candidiasis in patients treated with topical steroids for oral lichen planus (OLP) and to determine whether the application of a concurrent antifungal therapy prevented the development of an oral candidiasis in these patients. Records of 315 patients with OLP seen at four Oral Medicine practices treated for at least 2 weeks with steroids with and without the use of an antifungal regimen were retrospectively reviewed. The overall incidence of oral fungal infection in those treated with steroid therapy for OLP was 13.6%. There was no statistically significant difference in the rate of oral candidiasis development in those treated with an antifungal regimen vs those not treated prophylactically (14.3% vs 12.6%) (P = 0.68). Despite the use of various regimens, none of the preventive antifungal strategies used in this study resulted in a significant difference in the rate of development of an oral candidiasis in patients with OLP treated with steroids. © 2015 John Wiley & Sons A/S.

Podoplanin is a type I transmembrane sialomucin-like glycoprotein that is specifically expressed in lymphatic endothelial cells. Studies have shown that assessment of podoplanin expression in the epithelial cells can be used to predict the malignant transformation of potentially malignant disorders and the metastatic tendency of primary head and neck squamous cell carcinoma. The aim of our study was to compare the expression of podoplanin in oral leukoplakia, oral submucous fibrosis and oral squamous cell carcinoma with that in normal buccal mucosa by immunohistochemical methods. Immunohistochemical expression of podoplanin was analyzed in 20 cases each of oral leukoplakia, oral submucous fibrosis, oral squamous cell carcinoma and normal buccal mucosa, with monoclonal antibody D2-40. The expression of podoplanin was graded from grade 0-4. There was a statistically significant upregulation of the grades of podoplanin expression in oral squamous cell carcinoma(100%), oral submucous fibrosis (90%) and oral leukoplakia (65%) when compared to that in normal mucosa(35%). Podoplanin expression increased with decrease in grades of differentiation in oral squamous cell carcinoma . Podoplanin expression in the samples of oral submucous fibrosis was higher than that in oral leukoplakia. Evaluation of podoplanin expression in the epithelial cells of oral dysplastic lesions may provide valuable information to predict their risk of malignant transformation. Key words: Immunohistochemistry, Oral leukoplakia, Oral submucous fibrosis, Podoplanin, Squamous cell carcinoma.

The molecular complexity of the human oral cavity can only be clarified through identification of components that participate within it. However current proteomic techniques produce high volumes of information that are dispersed over several online databases. Collecting all of this data and using an integrative approach capable of identifying unknown associations is still an unsolved problem. This is the main motivation for this work. We present the online bioinformatic tool OralCard, which comprises results from 55 manually curated articles reflecting the oral molecular ecosystem (OralPhysiOme). It comprises experimental information available from the oral proteome both of human (OralOme) and microbial origin (MicroOralOme) structured in protein, disease and organism. This tool is a key resource for researchers to understand the molecular foundations implicated in biology and disease mechanisms of the oral cavity. The usefulness of this tool is illustrated with the analysis of the oral proteome associated with diabetes melitus type 2. OralCard is available at http://bioinformatics.ua.pt/oralcard.

Oral examinations and OHRQoL interviews were conducted with 871 15-year-olds as part of the Sixth Thailand National Oral Health Survey. The severity of oral impacts was categorized using "intensity". Associations between oral diseases and CS-OHRQoL were analyzed using chi-square and logistic regression. Thirty-nine percent of 15-year-olds experienced moderate/higher levels oral impacts on quality of life. Compared to those individuals with no tooth decay, adolescents with one or four or more decaying teeth were three and seven times more likely to experience moderate/higher impacts, respectively. Adolescents with extensive gingivitis in 3 or more mouth sextants were twice as likely to experience moderate/higher CS-impacts. Based on these findings, it is proposed that goals should focus on untreated decaying teeth and extensive gingivitis. Oral health goals for 15-year-olds should include specific OHRQoL measures.O objetivo deste estudo foi avaliar a associação entre doença bucal e a condição específica de qualidade de vida associada à saúde bucal (CS-OHRQoL, como base para propor OHRQoL metas para adolescentes tailandeses.

Full Text Available El tabaquismo corresponde a uno de los hábitos más comunes en la población mundial, tanto en hombres como en mujeres, siendo un factor de riesgo para el desarrollo de lesiones neoplásicas malignas y premalignas en la cavidad bucal. Las diferentes formas de utilización de este hábito, como fumar cigarrillo de manera convencional, tabaquismo invertido y pasivo, presentan variables en cuanto a la incidencia y prevalencia de aparición de tumores, así como el tipo, cantidad y la intensidad de tabaco consumido. Las células epiteliales que recubren la mucosa bucal reaccionan como mecanismos de defensa ante el estímulo del humo y la combustión, al igual que frente a los sustancias químico- tóxicas que de ellos provienen; manifestándose como lesiones que varían entre leucoedemas, hiperqueratosis nicotínicas, fibrosis epiteliales, lesiones precancerosas, carcinomas in situ, hasta el desarrollo de verdaderas neoplasias malignas. El estomatólogo juega un rol fundamental en el diagnóstico oportuno y la prevención de estas afecciones, puesto que está entrenado para detectar cualquier lesión en estado incipiente, y así simplificar su tratamiento, mejorando la calidad de vida del paciente; pero mucho más importante que detectar la lesión es prevenir que aparezca, orientando, población y combatiendo los factores de riesgo. Se presentan dos casos de pacientes fumadoras activas que acudieron al servicio de Estomatología y Cirugía Oral de la Fundación Universitaria San Martín, sede Puerto Colombia, por presentar lesiones tumorales en cavidad bucal semejantes clínicamente a carcinomas bucales; a quienes se les realizaron biopsias que confirmaron diagnósticos de carcinoma escamocelular.

1999-04-01

Interviews were conducted with 294 black residents (155 females and 138 males) of a peri-urban informal settlement in Gauteng to ascertain utilisation of oral health services, oral health needs and oral health status. Only 37 per cent of the sample had consulted a dentist or medical practitioner, usually for extractions. Teenagers and employed persons were significantly less likely to utilise dentists than the older age groups and unemployed persons. Forty per cent were currently experiencing oral health problems such as a sore mouth, tooth decay and bleeding/painful gums. Two hundred and twelve (73 per cent) interviewees wanted dental treatment or advice. Residents who rated their oral health status as fair or poor appeared to have the greatest need for oral health services. The use of interviews appears to be a cost-effective method of determining oral morbidity.

This study aimed to assess: (1) oral symptoms of patients treated for oral or oropharyngeal cancer; (2) how patients rank the burden of oral symptoms; (3) the impact of the tumor, the treatment, and oral symptoms on functional outcome. Eighty-nine patients treated for oral or oropharyngeal cancer were asked about their oral symptoms related to mouth opening, dental status, oral sensory function, tongue mobility, salivary function, and pain. They were asked to rank these oral symptoms according to the degree of burden experienced. The Mandibular Function Impairment Questionnaire (MFIQ) was used to assess functional outcome. In a multivariate linear regression analyses, variables related to MFIQ scores (p≤0.10) were entered as predictors with MFIQ score as the outcome. Lack of saliva (52%), restricted mouth opening (48%), and restricted tongue mobility (46%) were the most frequently reported oral symptoms. Lack of saliva was most frequently (32%) ranked as the most burdensome oral symptom. For radiated patients, an inability to wear a dental prosthesis, a T3 or T4 stage, and a higher age were predictive of MFIQ scores. For non-radiated patients, a restricted mouth opening, an inability to wear a dental prosthesis, restricted tongue mobility, and surgery of the mandible were predictive of MFIQ scores. Lack of saliva was not only the most frequently reported oral symptom after treatment for oral or oropharyngeal cancer, but also the most burdensome. Functional outcome is strongly influenced by an inability to wear a dental prosthesis in both radiated and non-radiated patients.

Associations between adult attachment and: oral health-related quality of life, oral health behaviour, and self-rated oral health.

Although adult attachment theory has been revealed as a useful theoretical framework for understanding a range of health parameters, the associations between adult attachment patterns and a range of oral health parameters have not yet been examined. The aim of this study was to examine potential associations between attachment insecurity and: (1) oral health-related quality of life (OHRQoL), (2) oral health behaviours, and (3) self-rated oral health. In association with this aim, sample characteristics were compared with normative data. The sample in this cross-sectional study was comprised of 265 healthy adults, recruited via convenience sampling. Data were collected on attachment patterns (Experiences in Close Relationships Scale-Short Form, ECR-S), OHRQoL (Oral Health Impact Profile-14, OHIP-14), oral health behaviours (modified Dental Neglect Scale, m-DNS), and self-rated oral health (one-item global rating of oral health). Multivariate regression models were performed. Both dimensions of attachment insecurity were associated with lowered use of favourable dental visiting behaviours, as well as decreased OHRQoL for both overall well-being and specific aspects of OHRQoL. Attachment avoidance was linked with diminished self-rated oral health. This study supports the potential value of an adult attachment framework for understanding a range of oral health parameters. The assessment of a client's attachment pattern may assist in the identification of people who are at risk of diminished OHRQoL, less adaptive dental visiting behaviours, or poorer oral health. Further research in this field may inform ways in which attachment approaches can enhance oral health-related interventions.

Patients were newly diagnosed oral squamous cell carcinoma cases according to the pathologic diagnoses, control subjects were enrolled from community population. Epidemiological data were collected by in-person interviews using a standard questionnaire. The contents of the questionnaire included demography character, history of tobacco smoking and alcohol drinking, dietary habits, oral hygiene status, family history of cancer, etc. Using unconditional logistic regression analysis to estimate adjusted odds ratios (OR) and corresponding 95% confidence intervals (CI) for oral hygiene and chronic diseases. We also stratified by sex, smoking and drinking to explore possible difference in association between subgroups. The multivariate logistic regression analysis indicated that number of teeth (20-27 and oral ulceration were the risk factors of oral squamous cell carcinoma, the adjusted OR (95% CI) values were 2.01 (1.49-2.73), 3.51 (2.39-5.15), 2.33 (1.79-3.04), 3.96 (2.11-7.44), respectively; brushing tooth once per bay, brushing tooth more than once per day, regular oral health examination at least 5 years per time were the protective factors of oral squamous cell carcinoma, the adjusted OR (95% CI) values were 0.24 (0.13-0.43), 0.13 (0.07-0.24), 0.37 (0.26-0.53), respectively. The stratification analysis indicated that recurrent oral ulceration could increase the risk of oral squamous cell carcinoma for non-smokers and non-drinking, the adjusted OR (95% CI) value was 5.21 (2.42-11.18) and 4.71 (2.37-9.36); and a risky effect of hypertension on risk of oral squamous cell carcinoma was observed for non-smokers and non-drinking, the adjusted OR (95% CI) values were 1.70 (1.10-2.61) and 1.58 (1.07-2.34).

The oral microbiome can alter the balance between health and disease, locally and systemically. Within the oral cavity, bacteria, archaea, fungi, protozoa, and viruses may all be found, each having a particular role, but strongly interacting with each other and with the host, in sickness or in health. A description on how colonization occurs and how the oral microbiome dynamically evolves throughout the host's life is given. In this chapter the authors also address oral and nonoral conditions in which oral microorganisms may play a role in the etiology and progression, presenting the up-to-date knowledge on oral dysbiosis as well as the known underlying pathophysiologic mechanisms involving oral microorganisms in each condition. In oral pathology, oral microorganisms are associated with several diseases, namely dental caries, periodontal diseases, endodontic infections, and also oral cancer. In systemic diseases, nonoral infections, adverse pregnancy outcomes, cardiovascular diseases, and diabetes are among the most prevalent pathologies linked with oral cavity microorganisms. The knowledge on how colonization occurs, how oral microbiome coevolves with the host, and how oral microorganisms interact with each other may be a key factor to understand diseases etiology and progression.

van der Meij, E H; Schepman, K P; de Visscher, J G A M

2013-09-01

The general dentist is sometimes confronted with white lesions of the oral mucosa. Oral lichen planus is the most common oral white lesion. The diagnosis can usually be made on the basis of the clinical aspect, but is sometimes made more difficult by certain abnormalities in the oral mucosa which clinically resemble oral lichen planus or by abnormalities which cannot be distinguished from oral lichen planus but have a different origin. Those lesions are classified as oral lichenoid lesions. Malignant deterioration has been described in allforms of oral lichen planus lesions and oral lichenoid lesions. There is no known method to predict or prevent malignant transformation. Nor are there any studies examining the efficacy of frequent follow-up visits. It seems sensible, in keeping with the tendency in recent literature, to schedule annual check-ups for patients to be on the safe side. These follow-up visits may reasonably be performed in a general dental practice.

Oral cancer in Chile corresponds approximately to 1.6% of all cancer cases. There are few studies about oral epithelial dysplasia and oral squamous cell carcinoma in the Chilean population. To determine the frequency of hyperkeratosis, mild, moderate and severe oral epithelial dysplasia, in situ carcinoma and squamous cell carcinoma of the oral and oropharyngeal mucosa in a registry of the Oral Pathology Reference Institute of the Faculty of Dentistry, Universidad de Chile, in a ten years period. Review of clinical records and pathological plates of 389 patients, obtained between 1990 and 2009. Cases were selected according to their pathological diagnosis, including hyperkeratosis, oral epithelial dysplasia, in situ carcinoma, squamous cell carcinoma and verrucous carcinoma. Forty four percent of cases were squamous cell carcinoma, followed by hyperkeratosis in 37% and mild epithelial dysplasia in 11%. Squamous cell carcinoma was more common in men aged over 50 years. Most of the potentially malignant disorders presented clinically as leukoplakia and squamous cell carcinoma were clinically recognized as cancer. In this study, men aged over 50 years are the highest risk group for oral cancer. Early diagnosis is deficient since most of these lesions were diagnosed when squamous cell carcinoma became invasive. Leukoplakia diagnosis is mostly associated with hyperkeratosis and epithelial dysplasia, therefore biopsy of these lesions is mandatory to improve early diagnosis.

2015-01-01

Full Text Available El artículo examina el concepto de leyenda como intangible territorial en diversas escalas, desde la local a la regional o nacional, y su relación con la construcción de mitos étnicos y la emergencia de tradiciones translocales. Para ello, se revisan la metodología de los estudios corográficos y las nociones de ecotipo y de paisaje cultural, así como la etnografía de los territorios simbólicos a la luz de conceptos como el clásico «témenos» y modernos como el «mytho-moteur» (Abadal, 1958. Se aplican estudios de casos que evidencian cómo es el Imaginario, en interacción con factores geohistóricos del lugar, el que a menudo acota y perimetrea un territorio a través de cauces como la fabulación legendaria y los ritos paralitúgicos, como procesiones o peregrinaciones. La conclusión es que las leyendas y los arquetipos de origen étnico y genealógico reescriben tradiciones que crean identidades y se pueden proyectar en ámbitos diferentes de la vida política o recreativa, con perfiles igualmente diferentes.

The purpose of this study was to analyze the relationship between oral bacterial colonization and oral motor dysfunction. Oral motor dysfunction (swallowing and speech disorders) and detection of oral bacterial species from dental plaque in 55 elderly persons who had remained hospitalized for more than 3 months were investigated and statistically analyzed. The detection rates of methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, Streptococcus agalactiae, and Stenotrophomonas maltophilia were significantly higher in subjects with than in those without a swallowing disorder. A similar result was found with regard to the presence of a speech disorder. About half of subjects who had oral motor dysfunction and hypoalbuminemia had colonization by MRSA and/or Pseudomonas aeruginosa. These results suggest that the combination of oral motor dysfunction and hypoalbminemia elevated the risk of opportunistic microorganisms colonization in the oral cavity of elderly patients hospitalized over the long term.

Oral health affects quality of life and is linked to overall health. Enhanced oral health research is needed in low- and middle-income countries to develop strategies that reduce the burden of oral disease, improve oral health and inform oral health workforce and infrastructure development decisions. To implement the first National Oral Health Survey of Rwanda to assess the oral disease burden and inform oral health promotion strategies. In this cross-sectional study, sample size and site selection were based on the World Health Organization (WHO) Oral Health Surveys Pathfinder stratified cluster methodologies. Randomly selected 15 sites included 2 in the capital city, 2 other urban centers and 11 rural locations representing all provinces and rural/urban population distribution. A minimum of 125 individuals from each of 5 age groups were included at each site. A Computer Assisted Personal Instrument (CAPI) was developed to administer the study instrument. Nearly two-thirds (64.9%) of the 2097 participants had caries experience and 54.3% had untreated caries. Among adults 20 years of age and older, 32.4% had substantial oral debris and 60.0% had calculus. A majority (70.6%) had never visited an oral health provider. Quality-of-life challenges due to oral diseases/conditions including pain, difficulty chewing, self-consciousness, and difficulty participating in usual activities was reported at 63.9%, 42.2% 36.2%, 35.4% respectively. The first National Oral Health Survey of Rwanda was a collaboration of the Ministry of Health of Rwanda, the University of Rwanda Schools of Dentistry and Public Health, the Rwanda Dental Surgeons and Dental (Therapists) Associations, and Tufts University and Harvard University Schools of Dental Medicine. The international effort contributed to building oral health research capacity and resulted in a national oral health database of oral disease burden. This information is essential for developing oral disease prevention and management

To determine whether a simple oral hygiene protocol improves the oral health of inpatients in stroke rehabilitation. Poor oral health can lead to serious complications, such as pneumonia. The comorbidities associated with stroke, such as dysphagia, hemiparesis and cognitive impairment, can further impede independent oral care. International stroke guidelines recommend routine oral care but stop short of detailing specific regimes. The oral health assessment tool (OHAT) was conducted by speech-language pathologists with 100 patients with and without dysphagia in three metropolitan inpatient stroke rehabilitation facilities. A simple nurse-led oral hygiene regime was then implemented with all participants, which included twice daily tooth brushing and mouth rinsing after lunch, and oral health was measured again one week later. Initially, dysphagia was negatively associated with OHAT scores, and independence for oral hygiene was positively associated with oral health. After one week of a simple oral hygiene regime, the OHAT scores available for 89 participants indicated an improvement on average for all participants. In particular, 59% of participants with dysphagia had an improvement of 1 or more points. None of the participants developed pneumonia. A simple, inexpensive oral hygiene regime resulted in positive outcomes for patients with and without dysphagia in inpatient stroke rehabilitation settings. Oral health assessments and oral hygiene regimes that are simple to implement by the interdisciplinary team can be incorporated into standard stroke care with positive effect. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

In the era of applied meta-omics and personalized medicine, the oral microbiome is a valuable asset. From biomarker discovery to being a powerful source of therapeutic targets and to presenting an opportunity for developing non-invasive approaches to health care, it has become clear that oral microbes may hold the answer for understanding disease, even beyond the oral cavity. Although our understanding of oral microbiome diversity has come a long way in the past 50 years, there are still many areas that need to be fine-tuned for better risk assessment and diagnosis, especially in early developmental stages of human life. Here, we discuss the factors that impact development of the oral microbiome and explore oral markers of disease, with a focus on the early oral cavity. Our ultimate goal is to put different experimental and methodological views into perspective for better assessment of early oral and systemic disease at an early age and discuss how oral microbiomes-at the community level-could provide improved assessment in individuals and populations at risk.

Mucosal involvement is commonly seen in patients with lupus; however, oral examination is often forgotten. Squamous cell carcinoma arising within oral lupoid plaques has been described, emphasizing the importance of identifying and treating oral lupus. We undertook a retrospective single-centre study looking at oral findings in patients attending our multidisciplinary lupus clinic between January 2015 and April 2016. A total of 42 patients were included. The majority of patients were female (88%) and had a diagnosis of discoid lupus erythematosus (62%). Half of the patients had positive oral findings, 26% had no oral examination documented, and 24% had documented normal oral examinations. Our findings suggest that oral pathology is common in this cohort of patients. Regular oral examination is warranted to identify oral lupus and provide treatment. Associated diseases such as Sjogren's syndrome may also be identified. Patients should be encouraged to see their general dental practitioners on a regular basis for mucosal review. Any persistent ulcer that fails to respond to treatment or hard lump needs urgent histopathological evaluation to exclude malignant transformation to squamous cell carcinoma.

Full Text Available Background Inflammatory Bowel Disease is known for its extra intestinal manifestations, the oral cavity is no exception. Objectives The aim of this study was to evaluate the association between Inflammatory Bowel Disease and oral mucosa lesions and symptoms, and complementary to evaluate their possible relation with oral hygiene, smoking habits, drug therapy, duration and activity of the disease. Methods Patients were selected from the Gastroenterology Clinic of a Portuguese tertiary referral hospital. This sample consisted of 113 patients previously diagnosed with ulcerative colitis or Crohn’s disease along with a control group of 58 healthy individuals that were accompanying the study group patients to their appointments. Clinical interviews and clinical examinations were performed for data collection. Results The patients in the study group were more affected by oral symptoms (P=0.011, and showed a trend towards a higher incidence of oral mucosal lesions, even though statistical significance was not reached (8.8% versus 3.4% in the control group; P=0.159. Patients in active phase were the most affected. No differences were detected between Crohn’s disease and ulcerative colitis, or concerning smoking habits. The corticosteroid and immunosuppressant therapy seemed to increase the incidence of oral symptoms (P=0.052. The oral mucosa lesions increased and the oral symptoms decreased over the course of the disease, however without statistical significance. Conclusion Oral mucosa’s lesions and oral symptoms were positively associated with Inflammatory Bowel Disease, mainly during disease activity periods and conceivably, associated with corticosteroid and immunosuppressant therapy.

Oral function improvement programs utilizing health behavior theories are considered to be effective in preventing the need for long-term social care. In the present study, an oral function improvement program based upon health behavior theories was designed, and its utility was assessed in 102 pre-frail elderly persons (33 males, 69 females, mean age: 76.9 +/- 5.7) considered to be in potential need of long-term social care and attending a long-term care prevention class in Sayama City, Saitama Prefecture, Japan. The degree of improvement in oral functions (7 items) and oral hygienic conditions (3 items) was assessed by comparing oral health before and after participation in the program. The results showed statistically significant improvements in the following oral functions: (1) lip functions (oral diadochokinesis, measured by the regularity of the repetition of the syllable "Pa"), (2) tongue functions, (3) tongue root motor skills (oral diadochokinesis, measured by the regularity of the repetition of the syllables "Ta" and "Ka"), (4) tongue extension/retraction, (5) side-to-side tongue movement functions, (6) cheek motor skills, and (7) repetitive saliva swallowing test (RSST). The following measures of oral hygiene also showed a statistically significant improvement: (1) debris on dentures or teeth, (2) coated tongue, and (3) frequency of oral cleaning. These findings demonstrated that an improvement program informed by health behavior theories is useful in improving oral functions and oral hygiene conditions.

Candida, an opportunistic fungal pathogen, has been implicated in oral and oesophageal cancers. This study aimed to examine oral Candida carriage in 52 oral cancer patients and 104 age-, gender- and denture status-matched oral cancer-free subjects. We assessed general health, smoking and alcohol drinking habits, use of alcohol-containing mouthwash and periodontal status (community periodontal index of treatment needs). Yeasts were isolated using oral rinse technique and genetically identified via Real-Time PCR-High resolution melting curve analysis of conserved ribosomal DNA. Conditional and binary logistic regressions were used to identify explanatory variables that are risk factors for oral cancer. The frequencies of oral yeasts' presence and high oral colonization were significantly higher in oral cancer than non-oral cancer patients (p=001; p=0.033, respectively). No significant difference in the isolation profile of Candida species was found between the two groups, except C. parapsilosis was more frequent in non-oral cancer group. Differences were noticed in the incidence of C. albicans strains where significantly more C. albicans genotype-A was isolated from cancer patients and significantly more C. albicans genotype-B isolated from non-cancer patients. Multiple regression analyses showed significant association with cancer observed for alcohol drinking (OR=4.253; 95% CI=1.351, 13.386), Candida presence (OR=3.242; 95% CI=1.505, 6.984) and high oral colonization (OR=3.587; 95% CI=1.153, 11.162). These results indicate that there is a significant association between oral cancer occurrence and Candida oral colonization and that the observed genotypic diversity of C. albicans strains may play a role in oral carcinogenesis.

Full Text Available Existe la creencia popular de que los lagartos del género Diplolaemus (Leiosauridae de Patagonia, Argentina, son capaces de conferir mordeduras venenosas que pueden causar inflamación e incluso la muerte de animales de granja o salvajes. No obstante, no existe evidencia de la existencia de glándulas de veneno en estos lagartos. La inflamación y absceso provocado como resultado de las heridas de mordedura podría ser causado por agentes infecciosos. Este es el primer estudio acerca de la microbiota oral de los lagartos del género Diplolaemus de Argentina. Para este trabajo se analizó un espécimen de D. darwini y tres individuos de Diplolaemus "forma alto patagonica". Las muestras de hisopados de boca de los lagartos fueron incubados aeróbica y anaeróbicamente, algunos de ellos fueron subcultivados en agar de sangre ovina al 5% e incubados nuevamente. Todas las colonias representativas observadas fueron subcultivadas para su purificación y sujetas a tests bioquímicos. La bacteria Clostridium perfigrens fue determinada por medio de la técnica de reacción en cadena de la Polimerasa. Se identificaron cuatro especies de bacterias: Staphylococus warneri, Clostridium bifermentans, Clostridium perfringens y Stomatococcus muscilaginosus. Estas especies son conocidas como agentes etiológicos de numerosas infecciones de humanos y animales. Si bien estas bacterias representan sólo un pequeño número de las posibles bacterias aisladas de la cavidad oral de Diplolaemus, están indicando la presencia de patógenos humanos y animales.

Full Text Available O objetivo inicial deste trabalho foi apreender a estrutura cognitiva de alunos do último ano (sétimo período do curso de graduação em odontologia da UFRJ em relação à temática do esmalte. Essa temática é de fundamental importância para a compreensão da saúde oral, na medida em que oferece conceitos científicos importantes e fundamentais para o exercício da prática clínica e preventiva, bem como por ser objeto de estudo em várias disciplinas ao longo do curso de Odontologia. Para a análise da estrutura cognitiva, utilizou-se a estratégia de mapas conceituais proposta por Novak e fundamentou-se na teoria da Aprendizagem Significativa, de Ausubel. A análise dos mapas elaborados pelos estudantes possibilitou um estudo não só sobre a estrutura cognitiva e as concepções sobre saúde oral dos alunos, como também permitiu um diagnóstico do conhecimento em diversos aspectos relevantes à formação científica e profissional, apontando para a necessidade de se repensar o processo ensino-aprendizagem nos cursos de Odontologia.This study sought to analyze senior dental students' cognitive structure concerning the topic of "enamel", which is fundamentally important for understanding oral health, since it offers basic scientific concepts for clinical and preventive practices and is the main subject of several courses during dentistry training. The strategy used to analyze students' cognitive structures was Novak's Concept Maps, based on Ausubel's Meaningful Learning theory. Analysis of students' maps allowed for a study of students' cognitive structure and concepts concerning oral health. It also fostered a diagnosis of students' knowledge in several important aspects of scientific and professional training. The results highlighted the need for rethinking the teaching/ learning process in dentistry training.

Como devemos compreender cultura e aprendizagem como instâncias produtoras delas próprias, e uma da outra, na prática? Recalibrando em termos relacionais, podemos dizer que não é possível abordar a “aprendizagem” ou “cultura e aprendizagem” sem o seu emaranhamento na vida político-econômica, nas lutas e disputas históricas, em suas coerências e incoerências, e na produção relacional e histórica da vida cotidiana. Através das lentes da teoria da prática social, os estudos etnográficos sobre aprendizagem na prática oferecem diferentes entendimentos sobre como certa vida e certas disputas e incoerências são produzidas.

Mast cells are granule containing secretory cells present in oral mucosal and connective tissue environment. Oral lichen planus and oral lichenoid lesions are commonly occurring oral diseases and have some similarity clinically and histologically. Both are characterized by an extensive sub epithelial infiltrate of T cells, together with mast cells, eosinophils and blood capillaries. In this study mast cell and eosinophil densities along with number of blood capillaries were studied to find out if they could aid in histopathological distinction between oral lichen planus and lichenoid mucositis. To enumerate mast cells and compare the status of Mast Cells (Intact or Degranulated) in Lichen planus, Lichenoid mucositis and normal buccal mucosa in tissue sections stained with Toluidine Blue, and also to enumerate Eosinophils and blood capillaries in tissue sections stained with H and E. The study group included 30 cases each of oral lichen planus and oral lichenoid mucositis. 10 cases of clinically normal oral buccal mucosa formed the control group. All the sections were stained with Toluidine blue and H and E separately. Histopathological analysis was done using binocular light microscope equipped with square ocular grid to standardize the field of evaluation. The result of the study showed. · Significant increase in number of mast cells in oral lichen planus and oral lichenoid mucositis compared to normal buccal mucosa. · Significant increase of intact mast cells suepithelially within the inflammatory cell infiltrate in oral lichen planus compared to oral lichenoid mucositis. · Significant increase of degranulated mast cells in oral lichenoid mucositis to oral lichen planus, and increase in number of eosinophil densities in oral lichenoid mucositis compared to oral lichen planus. · Significant increase in number of capillaries in oral lichenoid mucositis compared to oral lichen planus.

Various distresses appear in the terminal stage of cancer. Oral problems including dry mouth, stomatitis and candidiasis are one of the important problems which should be resolved. The purpose of this study was to investigate oral problems in this stage and improvement of dry mouth by oral care. The study subjects were consecutive terminally ill cancer patients admitted over the past 2 years. Patients were divided based on the status of oral food intake into good oral food intake group (≥30%) and poor oral food intake group. The following 3 items were retrospectively investigated: 1) The incidences of these oral problems, 2) Severity of dry mouth and complication with other oral problems, 3) Improvement of dry mouth using standard oral care by nursing staff and specialist oral care including dentists as needed. There were 115 and 158 patients in good and poor oral intake groups, respectively. 1) The incidences of dry mouth, stomatitis, and candidiasis were significantly higher in poor oral intake group ( p oral intake groups, respectively ( p oral intake group ( p = 0.0002). 3) The rate of dry mouth improvement by oral care was 100% in Grade-1, 86% in Grade-2 and 81% in Grade-3. Oral problems occur in many of terminally ill cancer patients. Accurate diagnosis of oral problems and corresponding appropriate interventions are important for improving quality of end-of-life care.

A pesquisa foi realizada em três escolas públicas da cidade de Araçatuba, Estado de São Paulo, com dez alunos em cada uma delas. Para a realização dos grupos focais foram abordadas as seguintes palavras, presentes em perguntas de questionários sobre saúde bucal, as quais apresentaram altos índices de erros: saúde bucal; placa bacteriana; dente permanente; flúor; gengiva sangra?; fio dental; transmissão da cárie. Durante as discussões dos grupos focais, observou-se que muitos adolescentes ficavam surpresos com a situação a qual foram submetidos e com o tema que estavam discutindo. A palavra ‘saúde bucal’ foi associada à condição de limpeza da cavidade bucal, não identificando a saúde bucal como parte da saúde geral. O termo ‘transmissão da cárie’ não teve um entendimento suficiente. A expressão ‘dente permanente’ foi bem compreendida, sendo associada a um tipo de dente que não seria mais substituído. A palavra ‘flúor’ teve maior associação à função de limpeza do que à proteção dos dentes.

A number of acute oral complications may be associated with cancer therapy in children, but the extent and duration of these complications, and the most effective management techniques. have not been well described. The few studies differ in design, making comparisons difficult. Well-controlled, prospective clinical studies are needed to define the most effective strategies for the management of acute oral complications in children. However, it is clear that dental intervention prior to cancer therapy is an important factor in the optimal preparation of the patient. During cancer therapy, intensive supervised oral preventive protocols appear to be of benefit to the child's oral health, overall comfort, and well-being. Furthermore, the prevention of oral infection may significantly reduce the morbidity associated with cancer therapy. Long-term preventive oral care may help prevent dental disease and infection in medically compromised children and contribute to improving the quality of life. 41 references

To investigate the association between critical and communicative oral health literacy (OHL) and oral health outcomes (status, oral health-related quality of life and practices) in adults. This cross-sectional study examined a household probability sample of 248 adults, representing 149,635 residents (20-64 years old) in Piracicaba-SP, Brazil. Clinical oral health and socioeconomic and demographic data, as well as data on oral health-related quality of life (OHIP-14) and health practices were collected. The oral examinations were carried out in the participants' homes, using the World Health Organization criteria for oral diseases. The critical and communicative OHL instrument was the primary independent variable, and it was measured using five Likert items that were dichotomized as 'high' ('agree' and 'strongly agree' responses for the 5 items) and 'low' OHL. Binary and multinomial logistic regressions were performed on each outcome (oral health status and practices), controlling for age, sex and socioeconomic status (SES). Approximately 71.5% presented low OHL. When adjusted for age and sex (first model) low OHL was associated with untreated caries (Odds Ratio = 1.92, 95% Confidence Interval = 1.07-3.45), tooth brushing oral health impact on quality of life (OR = 2.06, 1.15-3.69). Adjusting for age, sex and SES, OHL is related to a risk factor (biofilm) and a consequence of poor oral health (emergency dental visits) and can interfere with the impact of oral diseases on quality of life. As low OHL can be modified, the results support oral health promotion strategies directed at improving critical and communicative oral health literacy in adult populations.

Método: estudio con abordaje cualitativo que utilizó como referencial metodológico la historia oral. Se entrevistaron a ocho adolescentes matriculados en una escuela pública de Salvador, Bahía, Brasil, en el período de marzo a mayo de 2015. Los datos fueron sistematizados conforme al análisis temático y respaldados en referenciales teóricos sobre violencia doméstica y adolescencia. Resultados: los adolescentes con una infancia y adolescencia marcadas por la ausencia de atención a las necesidades físicas y emocionales, fundamentales para el crecimiento y desarrollo, y por la vivencia cotidiana de humillaciones, depreciaciones, difamaciones, calumnias, injurias, además de agresiones por medio de agresiones. Estos hallazgos se organizaron en las siguientes categorías: Negligencia y abandono; Violencia moral y psicológica; y la violencia física. Conclusión: considerando que la historia oral de los adolescentes desvela un contexto familiar permeado por las más variadas formas de expresión de la violencia, el estudio ratifica la realidad de abuso a que nuestros niños y adolescentes se encuentran expuestos dentro de sus hogares, entendidos como escenarios de protección y seguridad. Nos alerta, además, para la naturalización de la violencia intrafamiliar, socialmente arraigada en la creencia de la educación de los hijos a partir de medidas punitivas y coercitivas, más comúnmente por medio de castigos y agresiones físicas.

Con esta notación se reescribió el sistema de cokrigeage clásico como el sistema de krigeage de la RF univariada Z(x,i, asumiendo que esta posee un drift definido como m(x,i,j, donde los miembros fl(x,i,j de m(x,i,j pueden ser linealmente dependientes o independientes. Bajo esta notación el sistema de krigeage se reduce a un sistema univariado, la existencia de más de una variable o la presencia de heterotropía no impone la necesidad de manipulaciones extras para definir el sistema de ecuaciones de krigeage, incrementándose la eficiencia computacional.

Oral cancer is considered as a serious health problem resulting in high morbidity and mortality. Early detection and prevention play a key role in controlling the burden of oral cancer worldwide. The five-year survival rate of oral cancer still remains low and delayed diagnosis is considered as one of the major reasons. This increases the demand for oral screening. Currently, screening of oral cancer is largely based on visual examination. Various evidence strongly suggest the validity of visual inspection in reducing mortality in patients at risk for oral cancer. Simple visual examination is accompanied with adjunctive techniques for subjective interpretation of dysplastic changes. These include toluidine blue staining, brush biopsy, chemiluminescence and tissue autofluorescence. This review highlights the efficacy of various diagnostic methods in screening of oral cancer. © 2016 Old City Publishing, Inc.

Oral health is affected by its resident microorganisms. Three prominent oral disorders are dental caries, gingivitis and periodontitis, with the oral microbiota playing a key role in the initiation/progression of all three. Understanding the microbiota and the diseases they may cause is critical to the development of new therapeutics. This review is focused on probiotics for the prevention and/or treatment of oral diseases. This review describes the oral ecosystem and its correlation with oral health/disease. The pathogenesis and current prevention/treatment strategies of periodontal diseases (PD) and dental caries (DC) are depicted. An introduction of probiotics is followed by an analysis of their role in PD and DC, and their potential role(s) in oral health. Finally, a discussion ensues on the future research directions and limitations of probiotics for oral health. An effective oral probiotic formulation should contribute to the prevention/treatment of microbial diseases of the oral cavity. Understanding the oral microbiota's role in oral disease is important for the development of a therapeutic to prevent/treat dental diseases. However, investigations into clinical efficacy, delivery/dose optimization, mechanism(s) of action and other related parameters are yet to be fully explored. Keeping this in mind, investigations into oral probiotic therapies are proving promising.

Oral candidosis in relation to oral immunity.

Science.gov (United States)

Feller, L; Khammissa, R A G; Chandran, R; Altini, M; Lemmer, J

2014-09-01

Symptomatic oral infection with Candida albicans is characterized by invasion of the oral epithelium by virulent hyphae that cause tissue damage releasing the inflammatory mediators that initiate and sustain local inflammation. Candida albicans triggers pattern-recognition receptors of keratinocytes, macrophages, monocytes and dendritic cells, stimulating the production of IL-1β, IL-6 and IL-23. These cytokines induce the differentiation of Th17 cells and the generation of IL-17- and/or IL-22-mediated antifungal protective immuno-inflammatory responses in infected mucosa. Some immune cells including NKT cells, γδ T cells and lymphoid cells that are innate to the oral mucosa have the capacity to produce large quantities of IL-17 in response to C. albicans, sufficient to mediate effective protective immunity against C. albicans. On the other hand, molecular structures of commensal C. albicans blastoconidia, although detected by pattern-recognition receptors, are avirulent, do not invade the oral epithelium, do not elicit inflammatory responses in a healthy host, but induce regulatory immune responses that maintain tissue tolerance to the commensal fungi. The type, specificity and sensitivity of the protective immune response towards C. albicans is determined by the outcome of the integrated interactions between the intracellular signalling pathways of specific combinations of activated pattern-recognition receptors (TLR2, TLR4, Dectin-1 and Dectin-2). IL-17-mediated protective immune response is essential for oral mucosal immunity to C. albicans infection. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Oral microbiota and cancer

Full Text Available Inflammation caused by infections may be the most important preventable cause of cancer in general. However, in the oral cavity the role of microbiota in carcinogenesis is not known. Microbial populations on mouth mucosa differ between healthy and malignant sites and certain oral bacterial species have been linked with malignancies but the evidence is still weak in this respect. Nevertheless, oral microorganisms inevitably up-regulate cytokines and other inflammatory mediators that affect the complex metabolic pathways and may thus be involved in carcinogenesis. Poor oral health associates statistically with prevalence of many types of cancer, such as pancreatic and gastrointestinal cancer. Furthermore, several oral micro-organisms are capable of converting alcohol to carcinogenic acetaldehyde which also may partly explain the known association between heavy drinking, smoking, poor oral health and the prevalence of oral and upper gastrointestinal cancer. A different problem is the cancer treatment-caused alterations in oral microbiota which may lead to the emergence of potential pathogens and subsequent other systemic health problems to the patients. Hence clinical guidelines and recommendations have been presented to control oral microbiota in patients with malignant disease, but also in this area the scientific evidence is weak. More controlled studies are needed for further conclusion.

To determine the prevalence of oral and/or peri-oral piercings in young adults based on a systematic review of the available literature. The MEDLINE-PubMed, Cochrane-CENTRAL and EMBASE databases were comprehensively searched through April 2012 to identify appropriate studies. The prevalence of oral and/or peri-oral piercings was evaluated in the general population, as well as by gender and by anatomical site. An independent screening of 1711 unique titles and abstracts resulted in 13 publications that met the eligibility criteria. In total, 11 249 participants (mean age, 20.6 years) were questioned and/or examined for oral and/or peri-oral piercings. In the studies that provided information concerning the presence of oral and/or peri-oral piercings, the prevalence varied from 0.8% to 12%, resulting in a mean prevalence of 5.2%. When examined based on anatomical site, the most common sites were the tongue (a prevalence of 5.6%), followed by the lip (1.5%). Oral piercings were more prevalent in women (5.6%) than men (1.6%). Among the populations that were studied, oral and/or peri-oral piercings were observed in a relatively small percentage (5.2%) of young adults. The prevalence was approximately four times higher among females when compared with males. On the basis of the literature, the tongue was the most common oral site for a piercing. Dental care professionals are in an ideal position to offer information regarding safe piercings and to provide advice regarding oral hygiene, aftercare and possible complications. © 2012 John Wiley & Sons A/S.

Oral cancer has been recognized as a tumor with low sensitivity to anticancer agents. However, introduction of S-1, an oral cancer agent is improving treatment outcome for patients with oral cancer. In addition, S-1, as a main drug for oral cancer treatment in Japan can be easily available for outpatients. In fact, S-1 exerts high therapeutic effects with acceptable side effects. Moreover, combined chemotherapy with S-1 shows higher efficacy than S-1 alone, and combined chemo-radiotherapy with S-1 exerts remarkable therapeutic effects. Furthermore, we should consider the combined therapy of S-1 and molecular targeting agents right now as these combinations were reportedly useful for oral cancer treatment. Here, we describe our findings related to S-1 that were obtained experimentally and clinically, and favorable therapeutic strategies with S-1 against oral cancer with bibliographic considerations.

Oral mucositis is a side effect of chemotherapy, head and neck radiotherapy, and targeted therapy, affecting over 75% of high risk patients. Ulceration can lead to severe pain and difficulty eating and drinking, which may necessitate opioid analgesics, hospitalisation and nasogastric or intravenous nutrition. These complications may lead to interruptions or alterations to cancer therapy, which may reduce survival. There is also a risk of death from sepsis if pathogens enter the ulcers of immunocompromised patients. Ulcerative oral mucositis can be costly to healthcare systems, yet there are few preventive interventions proven to be beneficial. Oral cryotherapy is a low-cost, simple intervention which is unlikely to cause side-effects. It has shown promise in clinical trials and warrants an up-to-date Cochrane review to assess and summarise the international evidence. To assess the effects of oral cryotherapy for preventing oral mucositis in patients with cancer who are receiving treatment. We searched the following databases: the Cochrane Oral Health Group Trials Register (to 17 June 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue 5), MEDLINE via Ovid (1946 to 17 June 2015), EMBASE via Ovid (1980 to 17 June 2015), CANCERLIT via PubMed (1950 to 17 June 2015) and CINAHL via EBSCO (1937 to 17 June 2015). We searched the US National Institutes of Health Trials Registry, and the WHO Clinical Trials Registry Platform for ongoing trials. No restrictions were placed on the language or date of publication when searching databases. We included parallel-design randomised controlled trials (RCTs) assessing the effects of oral cryotherapy in patients with cancer receiving treatment. We used outcomes from a published core outcome set registered on the COMET website. Two review authors independently screened the results of electronic searches, extracted data and assessed risk of bias. We contacted study authors for information

In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

Sin embargo, en la actualidad existe un uso indiscriminado de estos, que trae consigo la resistencia bacteriana y por ende, la no efectividad del mismo. Se realizó un estudio en 40 pacientes que ingerían la tetraciclina debido a afecciones bucales de origen odontógeno, con el objetivo de conocer cuáles eran las enfermedades bucales donde esta se utilizaba indiscriminadamente, así como los mecanismos (automedicación o prescripción. Se obtuvieron comos resultados que las odontalgias por alteraciones pulpares y los abscesos dentoalveolares agudos son las patologías bucales donde se usa irracionalmente la tetraciclina, tanto en el fenómeno de automedicación como en la prescripción por parte de facultativos. La automedicación fue la vía dónde se evidenció mayor uso de la tetraciclina con el 67,5 %, y se observaron varios factores que condicionan este comportamiento. Existió un elevado porcentaje de no efectividad de este ante afecciones bucales debido al uso indiscriminado, ya sea por no ser el antibiótico de elección ante la patología o por ser ingerido innecesariamente.The use of antibiotics in treating infectious diseases was a breakthrough in the history of mankind. However, there is at present an excessive use of these drugs that leads to antimicrobial resistance and ineffectiveness. Forty patients, who took tetracycline for oral diseases of odontogenous origin, were studied to find out the oral diseases where this drug was overused as well as the intake mechanisms (self-medication or prescription. The achieved results showed that odontalgias from pulpar disturbances and acute dentoalveolary abscesses are the oral pathologies where tetracycline is irrationally overused through self-medication and prescription by physicians.

Entonces eran los descuentos que se empezaban a extender en las farmacias, francesas sobre todo, y que amenazaban el prestigio profesional de todo el colectivo. Con frases como éstas se define la situación que se presentaba en aquel momento: “…el desprestigio de que vaya por unos cuantos desnaturalizándose el ejercicio de la farmacia en tal forma que se convierta en un comercio impuro y de la peor estofa; pero conviene mucho combatir con mano firme la tendencia a la baratería, tanto más cuanto que no puede dudarse que significa un rebajamiento a todas luces nocivo y que supone una desorganización que nos llevaría en breve a la más completa ruina, y lo que creo aún más grave, a la desmoralización y el desorden, que no se compadecen en modo alguno con lo que en realidad es hoy y ha sido siempre el ejercicio de una profesión genuinamente científica como lo es la de la farmacia”. La propuesta que se hacía para controlar la situación era “la limitación de farmacias, con vigilancia estrecha del Estado y tarifa uniforme oficial”, así como “hace falta mucha inteligencia y mucha unión, hace falta que nadie permanezca indiferente, que todos y cada uno pongan de su parte lo que puedan”. Nuestra profesión mezcla una doble vertiente sanitaria y comercial que no siempre es fácil mantener equilibrada y, por lo que se ve, esto ha ocurrido así desde siempre. El problema que existe hoy en día es la mercantilización de la farmacia, un desplazamiento de establecimiento sanitario hacia una simple empresa.

Evaluation of tissue engineered models of the oral mucosa to investigate oral candidiasis.

Science.gov (United States)

Yadev, Nishant P; Murdoch, Craig; Saville, Stephen P; Thornhill, Martin H

2011-06-01

Candida albicans is a commensal organism that can be isolated from the majority of healthy individuals. However, in certain susceptible individuals C. albicans can become pathogenic leading to the mucocutaneous infection; oral candidiasis. Murine models and in vitro monolayer cultures have generated some data on the likely virulence and host factors that contribute to oral candidiasis but these models have limitations. Recently, tissue engineered oral mucosal models have been developed to mimic the normal oral mucosa but little information is available on their true representation. In this study, we assessed the histological features of three different tissue engineered oral mucosal models compared to the normal oral mucosa and analysed both cell damage and cytokine release following infection with C. albicans. Models comprised of normal oral keratinocytes and a fibroblast-containing matrix displayed more similar immunohistological and proliferation characteristics to normal mucosa, compared to models composed of an oral carcinoma cell line. Although all models were invaded and damaged by C. albicans in a similar manner, the cytokine response was much more pronounced in models containing normal keratinocytes. These data suggest that models based on normal keratinocytes atop a fibroblast-containing connective tissue will significantly aid in dissecting the molecular pathogenesis of oral candidiasis.

Poor oral hygiene has been suggested to be a risk factor for aspiration pneumonia in the institutionalized and disabled elderly. Control of oral biofilm formation in these populations reduces the numbers of potential respiratory pathogens in the oral secretions, which in turn reduces the risk for pneumonia. Together with other preventive measures, improved oral hygiene helps to control lower respiratory infections in frail elderly hospital and nursing home patients. Copyright © 2014 Elsevier Inc.

[Drug-induced oral ulcerations].

Madinier, I; Berry, N; Chichmanian, R M

2000-06-01

Different side effects of drugs have been described in the oral cavity, including oral ulcerations. Direct contact between drugs and oral mucosa may induce chemical burn or local hypersensitivity. Less frequently, these drug-induced oral ulcerations are part of a complex reaction with cutaneous or systemic manifestations. Sometimes, one or more oral ulcerations appear as the main side-effect of a drug, or exceptionally as solitary lesions. Solitary oral ulcerations usually appear after few weeks of treatment. In most of cases, these lesions resist to conventional treatments, with a rapid healing following the suppression of the responsible drug. This diagnosis is usually difficult, particularly with patients receiving multiple drug therapy. Besides, special attention must be paid to new drugs. Oral ulcerations following symptoms of burning mouth, metallic taste, dysgueusia or agueusia are strongly suggestive of a pharmacological origin. Most of the molecules able to induce solitary oral ulcerations are commonly prescribed in a) rheumatology: NSAI (diclofenac, flurbiprofen, indomethacin, naproxen), long-term rheumatoid arthritis therapy (azathioprine, methotrexate, penicillamine, gold compounds, tiopronin); b) cardiology: angiotensin-converting-enzyme inhibitors (captopril, enalapril), angiotensin 2-receptor antagonist (losartan), anti-angorous (nicorandil), c) psychiatry: antidepressants (fluoxetine, lithium), d) AIDS therapy (foscarnet, zalcitabine).

Multivariate modelling was used to calculate risk indicators for poor self-reported oral health. Results REALD-30 scores were lower among those who believed teeth should be infrequently brushed, believed cordial was good for teeth, did not own a toothbrush or owned a toothbrush but brushed irregularly. Tooth removal risk indicators included being older, problem-based dental attendance and believing cordial was good for teeth. Poor self-rated oral health risk indicators included being older, healthcare card ownership, difficulty paying dental bills, problem-based dental attendance, believing teeth should be brushed infrequently and irregular brushing. Perceived need for dental care risk indicators included being female and problem-based dental attendance. Perceived gum disease risk indicators included being older and irregular brushing. Feeling uncomfortable about oro-facial appearance risk indicators included problem-based dental attendance and irregular brushing. Food avoidance risk indicators were being female, difficulty paying dental bills, problem-based dental attendance and irregular brushing. Poor oral health-related quality of life risk indicators included difficulty paying dental bills and problem-based dental attendance. Conclusions REALD-30 was significantly associated with oral health literacy-related outcomes. Oral health literacy-related outcomes were risk indicators for each of the poor self-reported oral health domains among this marginalised population.

To systemically search the literature for case reports concerning adverse effects associated with oral and peri-oral piercings on oral health and/or general health.   MEDLINE and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched up through 1 April 2010 to identify appropriate studies. Independent screening of the titles and abstracts identified 1169 papers from MEDLINE and 73 papers from CENTRAL. Subsequently, 67 papers describing 83 cases were processed for data extraction. The case reports described complications in oral and general health. In this review, 96 complications were described for 83 cases. Of the 96 reported complications, 81% (n=84) occurred in cases of tongue piercings, 20% (n=21) in cases of lip piercings and 1% (n=1) in cases of other oral piercings. In eight cases, subjects had two oral and/or peri-oral piercings. Gingival recession was the most frequently described complication. Periodontitis and gingival recession were seen at the central mandibular incisors. Tooth fracture is mostly reported in subjects with tongue piercings. Among the case reports, there were complications like normal post-operative swelling and localized inflammation but also more serious complication that may even have been life threatening. Also in the long term, piercing may be associated with gingival recession and tooth fracture. Therefore, oral and/or peri-oral piercings are not without risks. Patients considering a piercing should be made aware of this. Those patients wearing a piercing should be screened by a dental professional for possible complications on a regular basis. © 2011 John Wiley & Sons A/S.

Oral lichen planus (OLP) is a chronic T cell mediated disease of oral mucosa, skin, and its appendages with a prevalence of 0.5 to 2.6% worldwide. Oral lichenoid reactions (OLR) are a group of lesions with diverse aetiologies but have clinical and histological features similar to OLP, thereby posing a great challenge in differentiating both lesions. Mast cells are multifunctional immune cells that play a major role in the pathogenesis of lichen planus by release of certain chemical mediators. Increased mast cell densities with significant percentage of degranulation have been observed as a consistent finding in pathogenesis of oral lichen planus. The current study was aimed at quantifying the mast cells in histopathological sections of OLP and OLR thereby aiding a means of distinguishing these lesions. The study group involved 21 cases of oral lichen planus, 21 cases of oral lichenoid reactions, and 10 control specimens of normal buccal mucosa. All the cases were stained with Toluidine Blue and routine haematoxylin and eosin and the mast cells were quantified. The results were analyzed using the Kruskal-Wallis test and an intergroup analysis was performed using Mann-Whitney U test. The number of mast cells showed an increased value in oral lichen planus when compared to oral lichenoid reaction and thus an estimation of mast cells count could aid in distinguishing OLP from OLR histopathologically.

Histológicamente se caracteriza por una proliferación vascular, infiltrado inflamatorio crónico y tejido de granulación. El objetivo del presente caso es describir las características clínicas e histológicas de un granuloma telangiectásico en cavidad oral y su plan de tratamiento. Llega a consulta paciente femenina de 50 años de edad, refiere presentar sangrado gingival en repetidas ocasiones en zona posterior de la arcada dentaria superior, durante el cepillado o con el consumo de algunos alimentos. Clínicamente se observa prótesis provisional desadaptada en órganos dentarios 11 al 15. Al retirar la prótesis es notorio un aumento de volumen en la encía interdental, con aspecto eritematoso, que sangra con facilidad. El reporte de anatomía patológica mostró una lesión con engrosamiento del epitelio escamoso, formación de nuevos vasos sanguíneos e infiltrado inflamatorio crónico. Diagnosticado como granuloma telangiectásico. La lesión fue eliminada quirúrgicamente por alargamiento coronal con reducción ósea. Ocho días después de la cirugía se evidencia proceso de cicatrización sin ninguna complicación. La lesión presentó recidiva transcurrido seis meses. Ello nos lleva a destacar la importancia del control de factores locales, como la presencia de prótesis desadaptadas y el acúmulo de placa bacteriana luego de la eliminación quirúrgica de este tipo de lesiones.

MÉTODO: estudo exploratório e descritivo, com 40 internos da Fundação Casa, entre 15 e 18 anos, da unidade UI 25 - Rio Negro, do complexo da cidade de Franco da Rocha - SP. Para a coleta de dados, foram aplicados o Teste do Mini-Exame do estado mental, com o objetivo de detectar eventuais alterações cognitivas; o Teste Montreal, que analisou habilidades simples de linguagem oral e escrita; e uma entrevista semi-estruturada, cujo roteiro versou sobre Saúde Geral, Trajetória Escolar, Trajetória Profissional e percepções sobre o comportamento infracional. RESULTADOS: verificou-se que a maior parte da população era alfabetizada e que não houve ocorrência de déficits cognitivos. Houve índice alto de abandono escolar, oriundo de dificuldades em acompanhar conteúdos escolares e se adaptar às regras e dinâmica escolar, o que indica impactos das dificuldades de linguagem, especialmente da linguagem escrita, em condição que, associadas a outros fatores, favoreceram os comportamentos infracionais. CONCLUSÃO: os jovens infratores apresentaram problemas para se desenvolver e se engajar a valores e normas sócio-culturais, como também escolares, o que impõe limites ao acesso e circulação discursiva desses sujeitos, restringindo os usos da linguagem, na condição de prática social ao desenvolvimento pessoal e da cidadania. Tais achados dão indícios, entre outros fatores, do impacto social que a precária escolarização e socialização dos jovens pode ajudar a acarretar. O estudo demonstra que a linguagem deve ser concebida como prática social, sobretudo, nas formas de expressão e de comunicação desses sujeitos.PURPOSE: to map and characterize the occurrence of oral and

Breath odor is a nuisance problem for many people around the world. Bad breath affects social interactions of people in daily life by causing personal discomfort and emotional stress. There are chemical and mechanical methods for controlling oral malodor. Many studies of various mouth rinse applications and tongue cleaning procedures have been conducted. However, few studies have compared the effect of simultaneous chemical and mechanical procedures on the reduction of volatile sulfur compounds (VSCs) in subjects with oral malodor. The purpose of this study was to assess the effects of different oral hygiene procedures on reduction of VSCs in subjects with oral malodor. Thirty male volunteers who matched with study criteria were divided randomly into two groups. Both groups performed tooth brushing, mouth washing with chlorine dioxide, tongue cleaning and combination of those in different sequence for five weeks. Total VSCs of subjects were measured with a Breathtron®, and oral health status was also examined. Quantitative analyses were performed using the Statistical Package for Social Science (SPSS 16.0). There were no significant differences in oral health status between the two groups at the baseline. No significant decrease in oral malodor was detected after one week of tooth brushing. Significant reductions in VSCs were shown by adding mouthwash or tongue cleaning to tooth brushing from the second week to fourth week (P oral hygiene regimens. Tooth brushing alone does not significantly reduce oral malodor. Mouth washing and tongue cleaning significantly reduce oral malodor, but combining tooth brushing, mouth washing and tongue cleaning regimens is most effective for oral malodor reduction. The results of this study could contribute to the formulation of appropriate preventive strategies against oral malodor not only for the general public but also for dental professionals serving as oral malodor-related service providers.

Full Text Available Abstract Background To investigate the association between critical and communicative oral health literacy (OHL and oral health outcomes (status, oral health-related quality of life and practices in adults. Methods This cross-sectional study examined a household probability sample of 248 adults, representing 149,635 residents (20–64 years old in Piracicaba-SP, Brazil. Clinical oral health and socioeconomic and demographic data, as well as data on oral health-related quality of life (OHIP-14 and health practices were collected. The oral examinations were carried out in the participants’ homes, using the World Health Organization criteria for oral diseases. The critical and communicative OHL instrument was the primary independent variable, and it was measured using five Likert items that were dichotomized as ‘high’ (‘agree’ and ‘strongly agree’ responses for the 5 items and ‘low’ OHL. Binary and multinomial logistic regressions were performed on each outcome (oral health status and practices, controlling for age, sex and socioeconomic status (SES. Results Approximately 71.5% presented low OHL. When adjusted for age and sex (first model low OHL was associated with untreated caries (Odds Ratio = 1.92, 95% Confidence Interval = 1.07–3.45, tooth brushing <3 times a day (OR = 2.00, 1.11–3.62 and irregular tooth flossing (OR = 2.17, 1.24–3.80. After SES inclusion in the first model, significant associations were found for low OHL when the outcomes were: presence of biofilm (OR = 1.83, 1.08–3.33, dental care for emergency only (OR = 2.24, 1.24–4.04 and prevalence of oral health impact on quality of life (OR = 2.06, 1.15–3.69. Conclusion Adjusting for age, sex and SES, OHL is related to a risk factor (biofilm and a consequence of poor oral health (emergency dental visits and can interfere with the impact of oral diseases on quality of life. As low OHL can be modified, the results support oral health promotion

Global Oral Health Inequalities

Science.gov (United States)

Garcia, I.; Tabak, L.A.

2011-01-01

Despite impressive worldwide improvements in oral health, inequalities in oral health status among and within countries remain a daunting public health challenge. Oral health inequalities arise from a complex web of health determinants, including social, behavioral, economic, genetic, environmental, and health system factors. Eliminating these inequalities cannot be accomplished in isolation of oral health from overall health, or without recognizing that oral health is influenced at multiple individual, family, community, and health systems levels. For several reasons, this is an opportune time for global efforts targeted at reducing oral health inequalities. Global health is increasingly viewed not just as a humanitarian obligation, but also as a vehicle for health diplomacy and part of the broader mission to reduce poverty, build stronger economies, and strengthen global security. Despite the global economic recession, there are trends that portend well for support of global health efforts: increased globalization of research and development, growing investment from private philanthropy, an absolute growth of spending in research and innovation, and an enhanced interest in global health among young people. More systematic and far-reaching efforts will be required to address oral health inequalities through the engagement of oral health funders and sponsors of research, with partners from multiple public and private sectors. The oral health community must be “at the table” with other health disciplines and create opportunities for eliminating inequalities through collaborations that can harness both the intellectual and financial resources of multiple sectors and institutions.

Dudhia, Bhavin B; Dudhia, Sonal B; Patel, Purv S; Jani, Yesha V

2015-01-01

The diagnosis between different diseases may be impaired by clinical and histopathologic similarities, as observed in the oral lichen planus (OLP) and oral lichenoid lesion (OLL). Inspite of similar clinicopathological features; etiology, diagnosis and prognosis differ which mandates separation of OLL from OLP. Hence, it is essential for the oral physician and oral pathologist to be familiarized with the individual variations among clinicopathological features of OLP and OLL as well as to obtain a thorough history and perform a complete mucocutaneous examination in addition to specific diagnostic testing. The difficulties faced to establish the diagnosis between these two pathologies are widely investigated in the literature with a lack of definite conclusion. This review is an attempt to throw some light on these clinicopathologic entities with the aim to resolve the diagnostic dilemma. PMID:26980966

Age-related oral changes.

LENUS (Irish Health Repository)

Mckenna, Gerald

2010-10-01

Age-related oral changes are seen in the oral hard and soft tissues as well as in bone, the temporomandibular joints and the oral mucosa. As older patients retain their natural teeth for longer, the clinical picture consists of normal physiological age changes in combination with pathological and iatrogenic effects. Clinical Relevance: With an ageing population retaining more of its natural teeth for longer, dental professionals should expect to observe oral age changes more frequently.

This study sought to advance understanding of the influence of psychosocial factors on oral health by examining how parental self-efficacy (with regard to acting on their child's oral health needs) and oral health knowledge relate to parental and child oral health behaviors and self-rated oral health. Parents of children in grades 0/1 and 5/6 (n = 804) and children in grades 5/6 (n = 377, mean age 11.5 ± 1.0, 53.9% female) were recruited from a stratified random sample of 11 primary (elementary) schools. Participants completed surveys capturing psychosocial factors, oral health-related knowledge, and parental attitudes about oral health. Parents also rated their own oral health status and the oral health of their child. Correlations and logistic regression analysis (adjusted for socioeconomic status, child age, and gender) examined associations between psychosocial factors and the outcomes of interest (parent and child behaviors and self-rated oral health status). Higher parental self-efficacy was associated with more frequent toothbrushing (by parent and child), and more frequent visits to a dental professional. These associations were particularly strong with regard to dental visits for children, with parents with the highest tertile for self-efficacy 4.3 times more likely to report that their child attended a dentist for a checkup at least once a year (95%CI 2.52-7.43); and 3 times more likely to report their child brushing their teeth at least twice a day (Adjusted Odds Ratio 3.04, 95%CI 1.64-5.64) compared with those parents in the lowest tertile for self-efficacy. No associations with oral health knowledge were found when examined by tertile of increasing knowledge. Oral health self-efficacy and knowledge are potentially modifiable risk factors of oral health outcomes, and these findings suggest that intervening on these factors could help foster positive dental health habits in families. © 2012 John Wiley & Sons A/S.

Full Text Available A insulina é um peptídeo biologicamente ativo, normalmente administrado por via subcutânea, pelos obstáculos que se colocam a sua administração oral. O desenvolvimento de uma forma farmacêutica passível de ser administrada oralmente tem sido razão de uma investigação persistente, acentuada na última década, conforme é descrito. As estratégias utilizadas têm sido muito variadas, a saber, a utilização de inibidores das enzimas proteolíticas, promotores da absorção, modificação química e fórmulas farmacêuticas específicas, como sistemas de partículas, emulsões, sistemas de liberação targeting e sistemas bioadesivos. Embora ainda nenhuma abordagem tenha sido suficientemente eficaz, os resultados são encorajadores. A microencapsulação e, em particular, os métodos que utilizam polímeros naturais, mostram-se promissores neste propósito, pelas características vantajosas que apresentam.Insulin is an important therapeutic protein, generally administered subcutaneously due to the obstacles of oral delivery. A number of different methods have been explored to improve the low oral bioavailability of insulin, particularly in the last decade, namely protease inhibitors, absorption enhancers, chemical modification and the formulation approach which includes particulate systems, emulsions, targeting delivery systems and bioadhesive systems. Although an effective formulation for oral insulin delivery remains to be achieved, the results are encouraging. Microencapsulation has proven to be a promising method of choice, especially when using natural polymers.

Full Text Available La presente investigación analiza los beneficios de la comunicación mediante teléfonos móviles para desarrollar las destrezas orales de los estudiantes en la segunda lengua. Un total de 80 estudiantes españoles que realizaban un curso de inglés nivel B1 en la Universidad de Almería participaron en el estudio. De acuerdo con el tipo de tratamiento, los sujetos fueron divididos en dos grupos, experimental y control. Mediante la creación de un grupo de «Whatsapp», 40 de dichos sujetos participaron en una interacción oral diaria durante 6 meses. Las muestras recogidas en la aplicación, así como un examen oral, fueron utilizados para analizar el grado en que los estudiantes desarrollan la destreza oral y los tipos y desencadenantes que dan lugar a episodios relacionados con el lenguaje en los chats orales. Este estudio se centra en la interacción utilizando un análisis mixto y un eje temporal con el fin de medir las diferencias entre los grupos analizados. Los resultados demuestran mejoras significativas en cuanto a la competencia oral en los alumnos del grupo en el que se implementó la actividad, siendo las negociaciones de significado el episodio relacionado con el lenguaje más común durante la interacción. Cabe destacar la accesibilidad que la mensajería móvil confiere a los alumnos, pues son capaces de negociar el significado, reflexionar y evaluar sus propias actuaciones mediante interacción real y feed-back.

The limited number of oral vaccines currently approved for use in humans and veterinary species clearly illustrates that development of efficacious and safe oral vaccines has been a challenge not only for fish immunologists. The insufficient efficacy of oral vaccines is partly due to antigen breakdown in the harsh gastric environment, but also to the high tolerogenic gut environment and to inadequate vaccine design. In this review we discuss current approaches used to develop oral vaccines fo...

Erosive oral lichen planus and desquamative gingivitis are uncommon but severe debilitating variants of oral lichen planus. Treatment of these presentations is difficult and challenging. A 44-year-old woman was referred to the dermatology clinic with chronic painful lichen planus-related gingivitis and buccal erosions. She has failed multiple treatments including topical clobetasol and tacrolimus, intralesional corticosteroids and several systemic and immunosuppressive agents. Following completion of three months of treatment with oral apremilast at a dose of 30 mg twice daily, significant improvement was noted in her disease activity. Oral apremilast may be a safe and effective treatment for erosive oral lichen planus.

Quantifying oral inflammatory load: oral neutrophil counts in periodontal health and disease.

Science.gov (United States)

Landzberg, M; Doering, H; Aboodi, G M; Tenenbaum, H C; Glogauer, M

2015-06-01

Neutrophils are the primary white blood cells that are recruited to fight the initial phases of microbial infections. While healthy norms have been determined for circulating blood neutrophil counts in order to identify patients with suspected systemic infections, the levels of oral neutrophils (oPMNs) in oral health and in the presence of periodontal diseases have not been described. It is important to address this deficiency in our knowledge as neutrophils are the primary immune cell present in the crevicular fluid and oral environment and previous work has suggested that they may be good indicators of overall oral inflammation and periodontal disease severity. The objective of this study was to measure oPMN counts obtained in a standardized oral rinse from healthy patients and from those with chronic periodontal disease in order to determine if oPMN levels have clinical relevance as markers of periodontal inflammation. A parallel goal of this investigation was to introduce the concept of 'oral inflammatory load', which constitutes the inflammatory burden experienced by the body as a consequence of oral inflammatory disease. Periodontal examinations of patients with a healthy periodontium and chronic periodontal disease were performed (n = 124). Two standardized consecutive saline rinses of 30 s each were collected before patient examination and instrumentation. Neutrophils were quantified in the rinse samples and correlated with the clinical parameters and periodontal diagnosis. Average oPMN counts were determined for healthy patients and for those with mild, moderate and severe chronic periodontal diseases. A statistically significant correlation was found between oPMN counts and deep periodontal probing, sites with bleeding on probing and overall severity of periodontal disease. oPMN counts obtained through a 30-s oral rinse are a good marker of oral inflammatory load and correlate with measures of periodontal disease severity. © 2014 John Wiley & Sons A

Towards understanding oral health.

Zaura, Egija; ten Cate, Jacob M

2015-01-01

During the last century, dental research has focused on unraveling the mechanisms behind various oral pathologies, while oral health was typically described as the mere absence of oral diseases. The term 'oral microbial homeostasis' is used to describe the capacity of the oral ecosystem to maintain microbial community stability in health. However, the oral ecosystem itself is not stable: throughout life an individual undergoes multiple physiological changes while progressing through infancy, childhood, adolescence, adulthood and old age. Recent discussions on the definition of general health have led to the proposal that health is the ability of the individual to adapt to physiological changes, a condition known as allostasis. In this paper the allostasis principle is applied to the oral ecosystem. The multidimensionality of the host factors contributing to allostasis in the oral cavity is illustrated with an example on changes occurring in puberty. The complex phenomenon of oral health and the processes that prevent the ecosystem from collapsing during allostatic changes in the entire body are far from being understood. As yet individual components (e.g. hard tissues, microbiome, saliva, host response) have been investigated, while only by consolidating these and assessing their multidimensional interactions should we be able to obtain a comprehensive understanding of the ecosystem, which in turn could serve to develop rational schemes to maintain health. Adapting such a 'system approach' comes with major practical challenges for the entire research field and will require vast resources and large-scale multidisciplinary collaborations. 2015 S.

Langerhans cells (LCs) are effective antigen-presenting cells that function as "custodians" of mucosa, modifying the immune system to pathogen entry, and tolerance to self-antigen and commensal microbes. A reduction in number of LCs in human immunodeficiency virus (HIV)-positive individuals may predispose to local mucosal infections. To quantitatively determine the number of oral mucosal LCs in HIV/acquired immunodeficiency syndrome HIV/acquired immunodeficiency syndrome (AIDS) associated oral Kaposi sarcoma (KS) with/without oral candidiasis (OC) and to define in situ interrelationships between the cells, OC, and HIV infection. Thirty-two periodic acid-Schiff. (PAS) stained histologic sections of palatal HIV/AIDS associated KS with intact oral epithelium were examined for Candida and divided into two groups: . (1) KS coinfected with Candida and. (2) KS noninfected with Candida. Sections were immunohistochemically stained with CD1a. The standard length of surface epithelium was measured and number of positively stained LCs counted per unit length. Control cases included non-Candida infected palatal mucosa overlying pleomorphic adenoma. (PA) and oral mucosa infected with Candida in otherwise healthy individuals. LC number per unit length of surface epithelium was statistically significantly greatest in uninfected PA mucosa and lowest in KS coinfected with Candida (P = 0.0001). A statistically significant difference was also noted between uninfected PA mucosa and non-Candida infected KS (P = 0.0014), in KS coinfected with Candida and non-infected KS (P = 0.0035), between OC and PA (P = 0.0001), and OC and KS coinfected with Candida (P = 0.0247). LC numbers are significantly reduced in oral tissues of HIV/AIDS infected patients by Candida infection when compared to oral tissues without.

Full Text Available Hacia finales del siglo XX, se produce el reingreso del testimonio oral como fuente para la producción de conocimiento histórico, y de la Memoria al universo de la Historia como vía de acceso al imaginario de los sujetos; ello significó la posibilidad de dar cuenta de la multiplicidad de filiaciones identitarias mantenidas “al margen”, antes silenciadas, que pueden activarse en los sujetos en atención al “otro” en confrontación al cual se construye.La recuperación de las escalas de abordaje microsociales -lo local, lo barrial-, indispensable para el propósito de comprensión de los fenómenos culturales/simbólicos, permitió la organización de nuevos campos cuya adscripción disciplinar resulta dificultosamente definida.En este marco se involucran los estudios que abordan los mecanismos que contribuyen a la construcción de identidades socioterritoriales -a escala intraurbana- utilizando relatos biográficos y observando el espacio que los acontecimientos recordados ocupan en el establecimiento de relaciones simbólicas con el territorio habitado.Con los propósitos señalados, y a partir de una experiencia concreta, se propone la reflexión desde una matriz transdisciplinar sobre los alcances y limitaciones de la instancia de entrevista grupal como espacio de participación comunitaria y dispositivo de co-construcción de datos.Como resultado, se dispone de una mirada metodológica ampliada hacia dimensiones epistemológicas, que asisten a las reacciones que enfrentan tanto los acercamientos ingenuos que pretenden una suerte de desaparición del investigador para dar voz al “otro”, como los que asumen que el investigador interpreta las interpretaciones de los entrevistados desde una posición privilegiada y distante.

This 10-year retrospective study analyzed the incidence of malignant transformation of oral lichen planus (OLP). The study also included dysplasia and oral lichenoid lesion (OLL) in the initial biopsy as a potential differential diagnosis. A total of 692 scalpel biopsies were taken from 542 patients (207 [38.2%] men and 335 [61.8%] women). Clinical and histopathological parameters were analyzed. The parameters gender (p = 0.022) and smoking behavior (p oral squamous cell carcinoma (OSCC). Smoking and joint disease appeared to be significant risk factors. Treatment with tretinoin in different concentrations (0.005-0.02%) significantly improved diagnosis. Twelve patients (8 female, 4 male) showed malignant transformation to OSCC within an average period of 1.58 years. The malignant transformation rate (MTR) was higher for OLL (4.4%) than OLP (1.2%). If the first biopsy showed intraepithelial neoplasia, the risk of developing OSCC increased (by 3.5% for squamous intraepithelial neoplasia (SIN) II and by 6.7% for SIN III). Although we cannot rule out that OLP is a premalignant oral condition, we can confirm that OLP had the lowest MTR of all diagnoses.

Full Text Available Background. Recent studies have demonstrated that podoplanin was expressed in some dysplastic lesions adjacent to primary oral cancers suggesting that podoplanin expression may occur in early oral tumorigenesis and lymphangiogenesis and therefore is related to tumor growth. The purpose of this study is to determine the role of podoplanin as a biomarker for cancer risk assessment in oral leukoplakia and correlation of podoplanin expression with grades of oral squamous cell carcinoma (OSCC. Materials and Methods. In the present retrospective study, podoplanin expression was investigated immunohistochemically in 40 patients each of oral leukoplakia and OSCC. The scores were analyzed statistically using one-way ANOVA test followed by Tukey HSD. Results. By applying one-way ANOVA test, there was a highly significant increase of the podoplanin expression from mild to severe dysplasia and from well to poorly differentiated OSCC (P<0.01. Statistically highly significant difference was present between scores of mild to moderate dysplasia, moderate to severe dysplasia, well to poorly differentiated OSCC, and moderately to poorly differentiated OSCC (Tukey HSD test, P<0.01. Conclusion. Podoplanin can be used as a biomarker for early oral tumorigenesis and for malignant transformation risk assessment of premalignant lesions and as a tumor progression biomarker for advanced grades of OSCC.

The objective of this study was to explore oral health-related behavior, how patients with diabetes differ from patients not diagnosed with diabetes in their oral health and whether oral health-related behavior moderates the oral health status of patients with diabetes. Survey and chart review data were collected from 448 patients (52% male, 48% female, average age: 57 years) of which 77 were diagnosed with diabetes (17%). Patients with diabetes had a higher percentage of teeth with mobility than those not diagnosed with diabetes (14% vs. 8%, p=0.023), as well as gingival recession (16% vs. 12%, p=0.035) and more teeth with recession in the esthetic zone (1.17 vs. 0.88, p=0.046). They also had more decayed, missing and filled surfaces due to caries (101 vs. 82, pteeth due to caries (11 vs. 7, pbrushed and flossed less frequently. Patients with diabetes who did not brush regularly had poorer periodontal health (percentage of teeth with probing depth of teeth: 32% vs. 15%, p=0.033) than regularly brushing patients with diabetes. Educating patients with diabetes about the importance of good oral self care needs to become a priority for their oral health care providers.

Full Text Available Background: The present study was undertaken to estimate and compare the levels of plasma total cholesterol (TC, low density lipoprotein (LDL, high density lipoprotein (HDL, very low density lipoprotein (VLDL and triglycerides in patients with oral precancerous lesions/conditions, oral cancer and normal subjects. Materials and Methods: The study comprised of 60 patients with oral precancerous lesions/conditions, 60 patients with oral cancer and a control group of 60 healthy individuals. The diagnosis of oral precancerous lesions/conditions and oral cancer was confirmed histopathologically. Under aseptic condition 5 ml venous blood of overnight fasting patient was withdrawn from each individual. Serum was separated by centrifugation and plasma levels of TC, LDL, HDL, VLDL and triglycerides were estimated. Descriptive statistical analysis has been carried out in the present study. Analysis of variance has been used to find the significance of study parameters between three or more groups of patients, Post-hoc test as Tukey has been used to find the pair wise significance. Significance is assessed at 5% level of significance. Results: Statistically significant decrease in levels of plasma TC, LDL, HDL, VLDL and triglycerides was observed in the precancerous and cancerous groups as compared to the control group. On comparison between precancerous and cancerous groups, significant decrease was observed in cancerous group. Conclusion: The change in lipid levels may have an early diagnostic or prognostic role in the oral premalignant lesions/conditions and oral cancer. The presence of decreased plasma lipid profile should increase the suspicion of these lesions to be investigated further.

The Oral Microbiota.

Arweiler, Nicole B; Netuschil, Lutz

2016-01-01

The oral microbiota represents an important part of the human microbiota, and includes several hundred to several thousand diverse species. It is a normal part of the oral cavity and has an important function to protect against colonization of extrinsic bacteria which could affect systemic health. On the other hand, the most common oral diseases caries, gingivitis and periodontitis are based on microorganisms. While (medical) research focused on the planktonic phase of bacteria over the last 100 years, it is nowadays generally known, that oral microorganisms are organised as biofilms. On any non-shedding surfaces of the oral cavity dental plaque starts to form, which meets all criteria for a microbial biofilm and is subject to the so-called succession. When the sensitive ecosystem turns out of balance - either by overload or weak immune system - it becomes a challenge for local or systemic health. Therefore, the most common strategy and the golden standard for the prevention of caries, gingivitis and periodontitis is the mechanical removal of this biofilms from teeth, restorations or dental prosthesis by regular toothbrushing.

Heightened interest in oral health has lead to an increase in patients complaining of xerostomia, which is associated with various oral mucosal disorders. In this study, we investigated the relationship between Candida species and oral mucosal disorders in patients with xerostomia. We evaluated whole salivary flow rate and presence of oral mucosal disorders in 48 patients with xerostomia and 15 healthy controls. The number of Candida species was measured as colony-forming units after propagation on selective medium. Identification of Candida at the species level was carried out by polymerase chain reaction and restriction fragment length polymorphism analysis. We then examined the relationship between Candida species and oral mucosal symptoms. Compared with controls, patients with xerostomia exhibited significantly decreased whole salivary flow rate, increased rate of oral mucosal symptoms, and higher numbers of Candida. Salivary flow rate negatively correlated with the number Candida. Among patients with oral candidiasis, Candida albicans was isolated from the tongue mucosa and Candida glabrata was isolated from the angle of the mouth. These results suggest that particular Candida species are involved in the pathogenesis of oral mucosal disorders in patients with xerostomia. © 2012 John Wiley & Sons A/S.

The World Health Organization has stated that psychiatric patients are a group of people who have oral and dental illnesses. The aims of this study were to document the oral hygiene of individuals with chronic psychiatric illness, to determine the extraoral and intraoral findings, to detect the dominant microorganisms in oral flora, and to inform clinicians of these findings. The study included 100 patients (69 men and 31 women) with different psychiatric illnesses living in a nursing home. They were 19-96 years old (median, 48 years). The participants completed a questionnaire about patients' oral health. They underwent extraoral and intraoral examinations. Two swab samples were obtained from the oral mucosa of these patients. Gram preparations were analyzed for leukocytes, bacteria, and yeast. Chi-square test and z-test were used. All patients (100%) had the necessary equipment for oral hygiene; however, many (43%) patients had poor oral hygiene. There was a high prevalence of xerostomia (56%) and fissured tongue (61.4%) (among other tongue anomalies). The most commonly isolated microorganisms were coagulase-negative Staphylococcus0 (35.9%), Streptococcus spp. (30.3%), nondiphtheroid Bacilli (16.9%), Staphylococcus aureus (2.3%), Candida spp. (11.8%), and Gram-negative Bacilli (2.8%). The oral hygiene of most patients was insufficient. The presence of Gram-negative Bacilli growth in the oral flora can be explained by poor hand hygiene. These findings suggest that it is useful to educate individuals about oral hygiene and hand hygiene and to inform the staff and families about this issue.

Esta enfermedad no excluye a la población infantil, aunque se presenta en baja frecuencia, constituye una de las tres causas de muerte en niños. El tratamiento antineoplásico a través de los años ha logrado porcentajes altos de curaciones, sin embargo, los grados de toxicidad que afectan a las células normales han aumentado por la intensidad de los tratamientos, siendo la cavidad oral muy susceptible a los efectos adversos directos e indirectos de la quimioterapia y radioterapia, debido a un alto índice de renovación celular. Dichas manifestaciones orales de carácter aguda o crónicas se ven agravadas por los problemas odontológicos preexistentes (caries, gingivitis y mala higiene. Es importante para el odontólogo conocer dichas alteraciones, identificarlas y así poder asistir adecuadamente a los pacientes para mejorar la calidad de vida. En este artículo se describen las alteraciones que se presentan con más frecuencia así como la experiencia y manejo clínico dentro del servicio de odontopediatría del Instituto Nacional de Enfermedades Neoplásicas.

This systematic review analyzed the strength of the literature and defined clinical practice guidelines for the use of oral cryotherapy for the prevention and/or treatment of oral mucositis caused by cancer therapy. A systematic review on relevant oral cryotherapy studies indexed prior to 31 December 2010 was conducted by the Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society for Oral Oncology (MASCC/ISOO) using OVID/MEDLINE, with publications selected for review based on defined inclusion and exclusion criteria. Findings from the reviewed studies were integrated into guidelines based on the overall level of evidence for each intervention. Guidelines were classified into three types: recommendation, suggestion, or no guideline possible. Twenty-two clinical studies and two meta-analyses were analyzed. Results were compared with the MASCC/ISOO guidelines published in 2007. The recommendation for the use of oral cryotherapy to prevent oral mucositis in patients receiving bolus fluorouracil (5-FU) was maintained, in agreement with the 2007 guidelines. A suggestion for use of oral cryotherapy to prevent oral mucositis in patients receiving high-dose melphalan as conditioning regimen with or without total body irradiation for HCST was revised from the 2007 guidelines. No guideline was possible for any other intervention, due to insufficient evidence. The evidence continues to support the use of oral cryotherapy for prevention of oral mucositis in patients receiving bolus 5-FU chemotherapy or high-dose melphalan. This intervention is consistent with the MASCC/ISOO guidelines published in 2007. The literature is limited by the fact that utilization of a double-blind study design is not feasible. Future studies that compare efficacy of oral cryotherapy with other mucositis agents in patients receiving chemotherapy with relatively short plasma half-lives would be useful.

In the present study, the relationship between the turbidity of mouth-rinse water and oral health conditions, including oral malodor, in patients with (n = 148) and without (n = 231) periodontitis was examined. The turbidity of 20 mL distilled water that the patients rinsed in their mouths 10 times was measured using a turbidimeter. Oral malodor was evaluated using an organoleptic test and Oral Chroma. Oral health conditions, including decayed teeth, periodontal status, oral hygiene status, proteolytic activity of the N-benzoyl-dl-arginine-2-napthilamide (BANA) test on the tongue coating, and salivary flow rate, were assessed. Turbidity showed significant correlations with oral malodor and all oral health parameters in the periodontitis group. In the non-periodontitis group, turbidity showed significant correlations with oral malodor and oral health parameters, including dental plaque, tongue coating, BANA test, and salivary flow rate. The regression analysis indicated that turbidity was significantly associated with methyl mercaptan and the BANA test in the periodontitis group, and with hydrogen sulfide, dental plaque, tongue coating, and salivary flow rate in the non-periodontitis group. The findings of the present study indicate that the turbidity of mouth-rinse water could be used as an indicator of oral health conditions, including oral malodor. © 2013 Wiley Publishing Asia Pty Ltd.

This study aims to comprehensively assess the association of subjective and objective oral health status and oral health behaviors with happiness, under consideration of demographic, socioeconomic, and general health-related factors. This study also aims to test whether subjective oral health outcomes are better predictors of happiness compared with objective oral health outcomes. The data were collected from 479 community-dwelling elders aged 65 years or over selected by a cluster sampling method. A questionnaire and an oral examination were implemented. A multiple regression method was conducted to assess associations with happiness index (HI). The mean age of the elders was 74.6 years. Mean (standard deviation, SD) HI, EuroQol-visual analog scale (EQ-VAS) and 14-item oral health impact profile (OHIP-14) index were 5.7 (SD 2.3), 59.8 (SD 21.1), and 16.3 (SD 13.1). In the final model, a significant association with HI of the OHIP-14 index (P = 0.091) among all the participants and significant associations of oral symptoms (P = 0.038), wearing a removable denture (P = 0.039), and of the oral health behavior of daily toothbrushing (P = 0.007) among poorer oral health QoL group were confirmed under consideration of other related factors. While correlations of HI to subjective measures of health, EQ-VAS and OHIP-14 score were moderate to weak, those to objective measures of health were only weak or insignificant. Oral impacts which might persistently affect one's daily life need to be considered in designing and delivering public services aimed to promote people's happiness. With oral health impacts and behaviors accounting for 10% of happiness among elders, public and community services for the elderly that support oral health and daily toothbrushing for the dentate are critical for the well-being of our elders. © 2013 John Wiley & Sons A/S.

Full Text Available O foco deste trabalho é refletir sobre a montagem cinematográfica como ato criativo, não a montagem pensada como simples agenciadora de planos, mas como criadora de sentidos. É na maneira como o cinema articula e aproxima as imagens e os sons que verificamos sua transformação em discurso. Criam-se novos sentidos, uma nova lógica onde os significados não são transparentes, nascida da associação de fragmentos. Justapõem-se duas realidades: a da vida propriamente dita e a do filme, a do discurso e, ainda dentro do filme, a justaposição de planos determinando novas leituras das Imagens. Partindo dos princípios da teoria da montagem cinematográfica de S. M. Eisenstein, faremos um rápido panorama de como o cinema, no decorrer de sua história, foi influenciado pelos conceitos desenvolvidos em sua teoria.

Pathogenesis of oral FIV infection.

Directory of Open Access Journals (Sweden)

Craig Miller

Full Text Available Feline immunodeficiency virus (FIV is the feline analogue of human immunodeficiency virus (HIV and features many hallmarks of HIV infection and pathogenesis, including the development of concurrent oral lesions. While HIV is typically transmitted via parenteral transmucosal contact, recent studies prove that oral transmission can occur, and that saliva from infected individuals contains significant amounts of HIV RNA and DNA. While it is accepted that FIV is primarily transmitted by biting, few studies have evaluated FIV oral infection kinetics and transmission mechanisms over the last 20 years. Modern quantitative analyses applied to natural FIV oral infection could significantly further our understanding of lentiviral oral disease and transmission. We therefore characterized FIV salivary viral kinetics and antibody secretions to more fully document oral viral pathogenesis. Our results demonstrate that: (i saliva of FIV-infected cats contains infectious virus particles, FIV viral RNA at levels equivalent to circulation, and lower but significant amounts of FIV proviral DNA; (ii the ratio of FIV RNA to DNA is significantly higher in saliva than in circulation; (iii FIV viral load in oral lymphoid tissues (tonsil, lymph nodes is significantly higher than mucosal tissues (buccal mucosa, salivary gland, tongue; (iv salivary IgG antibodies increase significantly over time in FIV-infected cats, while salivary IgA levels remain static; and, (v saliva from naïve Specific Pathogen Free cats inhibits FIV growth in vitro. Collectively, these results suggest that oral lymphoid tissues serve as a site for enhanced FIV replication, resulting in accumulation of FIV particles and FIV-infected cells in saliva. Failure to induce a virus-specific oral mucosal antibody response, and/or viral capability to overcome inhibitory components in saliva may perpetuate chronic oral cavity infection. Based upon these findings, we propose a model of oral FIV pathogenesis

Background To determine the prevalence and clinicopathologic features of the oral cancer patients. Material and Methods Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Results Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Conclusions Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as

Ethnicity and oral cancer.

Science.gov (United States)

Scully, C; Bedi, R

2000-09-01

Oral squamous-cell carcinoma, the main type of oral cancer, is among the ten most common cancers in the world. The aims of this paper were first, to consider whether there was evidence of marked ethnic variations in the incidence, management, and survival of oral cancer, and then, to review possible explanations for these variations. Evidence from the literature suggests that there is marked, inter-country variation in both the incidence and mortality from oral cancer. There is also growing evidence of intracountry ethnic differences, mostly reported in the UK and USA. These variations among ethnic groups have been attributed mainly to specific risk factors, such as alcohol and tobacco (smoking and smokeless), but dietary factors and the existence of genetic predispositions may also play a part. Variations in access to care services are also an apparent factor. The extent of ethnic differences in oral cancer is masked by the scarcity of information available. Where such data are accessible, there are clear disparities in both incidence and mortality of oral cancer between ethnic groups.

The existence of extra-pineal melatonin has been observed in various tissues. No prior studies of melatonin in human oral mucosal tissue under the condition of chronic inflammation have been reported. The aim of this study was to investigate the presence of melatonin in oral mucosal tissue of patients with oral lichen planus (OLP) which was considered as a chronic inflammatory immune-mediated disease causing oral mucosal damage and ulcerations. Sections from formalin-fixed and paraffin-embedded oral mucosal tissue of OLP patients (n=30), and control subjects (n=30) were used in this study. Immunohistochemical staining was performed and the semiquantitative scoring system was used to assess the levels of arylalkylamine-N-acetyltransferase (AANAT: a rate-limiting enzyme in the biosynthesis pathway of melatonin), melatonin, and melatonin receptor 1 (MT1) in oral mucosa of OLP patients and normal oral mucosa of control subjects. AANAT, melatonin, and MT1were detected in oral mucosal tissue of OLP patients and control subjects. Immunostaining scores of AANAT, melatonin, and MT1 in oral mucosal tissue of OLP patients were significantly higher than those in control subjects (p=0.002, poral mucosal tissue of OLP patients imply that chronic inflammation may induce the local biosynthesis of melatonin via AANAT, and may enhance the action of melatonin via MT1.

The Liverpool Oral Rehabilitation Questionnaire (LORQ) and Oral Health Impact Profile (OHIP) are specific tools that measure OHRQOL. The primary objective of this study was to assess the impact of oral rehabilitation on patients' OHRQOL following treatment for cancer of oral cavity using LORQ version 3 (LORQv3) and OHIP-14 questionnaire. Secondary objectives were to identify issues specific to oral rehabilitation, patients compliance to prosthetic rehabilitation, the effect of radiation treatment on prosthetic rehabilitation, to achieve meaningful differences over a time before & after prosthetic intervention, to carryout and document specific patient-deprived problem. Seventy-five oral cancer patients were studied. Patients were asked to rate their experience of dental problems before fabrication of prosthesis and after 1 year using LORQv3 and OHIP-14. The responses were compared on Likert scale. Patients reported with extreme problems before rehabilitation. After 1 year of prosthetic rehabilitation, there was improvement noticed in all the domain of LORQv3 and OHIP-14. Complete compliance to the use of prosthetic appliances for 1 year study period was noted. In response to the question no. 40 (LORQv3), only 15 patients who belonged to the obturator group, brought to notice the problems which were not addressed in the LORQv3 questionnaire. The study showed that the oral cancer patients coped well and adapted to near normal oral status after prosthetic rehabilitation. This contributed to the improved overall health-related quality of life.

Maintaining women's oral health.

Women must adopt health-promoting strategies for both general health and the oral cavity, because the health of a woman's body and oral cavity are bidirectional. For general health-maintenance strategies, dental practitioners should actively advise women to minimize alcohol use, abstain from or cease smoking, stay physically active, and choose the right foods to nourish both the body and mind. For oral health-maintenance strategies, dental practitioners should advise women on how to prevent or control oral infections, particularly dental caries and periodontal diseases. Specifically, women need to know how to remove plaque from the teeth mechanically, use appropriate chemotherapeutic agents and dentifrices, use oral irrigation, and control halitosis. Dental practitioners also need to stress the importance of regular maintenance visits for disease prevention. Adolescent women are more prone to gingivitis and aphthous ulcers when they begin their menstrual cycles and need advice about cessation of tobacco use, mouth protection during athletic activities, cleaning orthodontic appliances, developing good dietary habits, and avoiding eating disorders. Women in early to middle adulthood may be pregnant or using oral contraceptives with concomitant changes in oral tissues. Dental practitioners need to advise them how to take care of the oral cavity during these changes and how to promote the health of their infants, including good nutrition. Older women experience the onset of menopause and increased vulnerability to osteoporosis. They may also experience xerostomia and burning mouth syndrome. Dental practitioners need to help women alleviate these symptoms and encourage them to continue good infection control and diet practices.

Psychological stress appears to contribute to poor oral health systemically in combination with other chronic diseases. Few studies directly examine this relationship. Data from a cross-sectional study of 2,412 participants between the ages of 25-64 years old living in the City of Toronto between 2009 and 2012 were used to examine the relationship between current stress and two self-rated oral health outcomes (general oral health and oral pain). Dental care utilization and access to dental insurance were examined as effect modifiers. A positive relationship between current stress and poor oral health was observed for both outcomes (oral pain coefficient 0.32, 95 % CI 0.26-0.38; general oral health coefficient 0.28, 95 % CI 0.19-0.36). Effects on oral pain were stronger for the uninsured, while effects on general oral health were stronger with decreasing socioeconomic position. Our findings suggest that individuals with greater perceived stress also report poorer oral health, and that this relationship is modified by dental insurance and socioeconomic position. These findings warrant a greater focus on the role of psychological stress in the development of oral disease, including how perceived stress contributes to health inequities in self-reported oral health status. Patients experiencing stressful lives may differentially require closer monitoring and more vigilant maintenance of their oral health, above and beyond that which is needed to achieve a state of health in the oral environment of less stressed individuals. There may be health promoting effects of addressing psychosocial concerns related to dental care - particularly for the poor and uninsured.

El Derecho como práctica y como discurso. La perspectiva de la persona como garantía de objetividad y razonabilidad en la interpretación

Full Text Available El trabajo se propone ofrecer una comprensión tanto de los orígenes como de los límites de la problematicidad de la interpretación jurídica -en particular, aunque no de modo único, de la interpretación constitucional-, focalizada en la estructura intencional del Derecho como discurso escrito y como práctica social. En cuanto discurso, el Derecho se concibe como un conjunto de "actos del habla"; en tanto práctica social, la comprensibilidad del Derecho se vincula a los fines o a las intenciones que se proponen sus participantes y que lo distinguen de otras prácticas sociales. Se concluye desde esta doble perspectiva que, lejos de ser un método entre otros, la interpretación teleológica es la estructura formal indisponible de toda interpretación jurídica. Sobre esta base se intenta mostrar que, aunque la proyección teleológica del Derecho opere como causal de la problematicidad de la interpretación jurídica, al mismo tiempo se constituye en el límite o marco para la dimensión creativa de la interpretación. A partir de aquí se defiende la tesis de que la problematicidad de la interpretación jurídica no es sinónimo de arbitrariedad en el Derecho constitucionalizado, al menos si se asumen dos postulados. Primero, que la abstracción del lenguaje jurídico es indeterminación, pero no vaguedad. Segundo, que los fines últimos del Derecho se ligan a una concepción de persona objetiva -metafísica, no política-.

Full Text Available Introduction: Fractal analysis (FA quantifies complex geometric structures by generating a fractal dimension (FD, which can measure the complexity of mucosa. FA is a quantitative tool used to measure the complexity of self-similar or semi-self-similar structures. Aim and Objective: The study was done to perform the FA of oral mucosa with keratotic changes, as it is also made up of self-similar tissues, and thus, its FD can be calculated. Results: In oral leukoplakia, keratinization increases the complexity of mucosa, which denotes fractal geometry. We evaluated and compared pretreated and post-treated oral leukoplakia in 50 patients with clinically proven oral leukoplakia and analyzed the normal oral mucosa and lesional or keratinized mucosa in oral leukoplakia patients through FA using box counting method. Conclusion: FA using the fractal geometry is an efficient, noninvasive prediction tool for early detection of oral leukoplakia and other premalignant conditions in patients.

Full Text Available RESUMEN: Habitar las ciudades es un proceso en el que se encuentran anudadas cuestiones materiales y simbólicas. Este lazo debe ser atendido y puesto en valor en términos históricos y culturales ya que forma parte de nuestro aprendizaje como sujetos urbanos. En este sentido, tal como afirma Andreas Huyssen (2002: 191 "...la ciudad funciona como un tipo de prisma" que permite "enfocar" una multiplicidad de temáticas que no están solo ligadas al urbanismo o a la arquitectura, sino también a experiencias culturales y construcciones simbólicas que articulan el hecho concreto de vivir en las ciudades. Es así que, siguiendo a este autor, podemos afirmar que la ciudad es un texto que puede ser leído como un verdadero espacio de signos. Una casa, un barrio, un edificio, los espacios públicos, las calles y veredas, los monumentos son reservorios de un tiempo y una memoria que requieren de una multiplicidad de lecturas para transformarse en escenarios de aprendizajes integradores. Cuestionar a la ciudad como territorio de la educación integral así como reconocer las cuestiones centrales que se ponen a prueba cuando esto se postula como una política pública son los objetivos principales del presente artículo, para lo cual proponemos un recorrido a partir de considerar conceptos nodales como los de educación integral y pedagogía urbana.

Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the aim of our study was to evaluate oral yeast colonization throughout pregnancy and to compare it with non-pregnant women. The oral yeast colonization was assessed in saliva of 30 pregnant and non-pregnant women longitudinally over a 6-months period. Demographic information was collected, a non-invasive intra-oral examination was performed and saliva flow and pH were determined. Pregnant and non-pregnant groups were similar regarding age and level of education. Saliva flow rate did not differ, but saliva pH was lower in pregnant than in non-pregnant women. Oral yeast prevalence was higher in pregnant than in non-pregnant women, either in the first or in the third trimester, but did not attain statistical significance. In individuals colonized with yeast, the total yeast quantification (Log10CFU/mL) increase from the 1st to the 3rd trimester in pregnant women, but not in non-pregnant women. Pregnancy may favour oral yeast growth that may be associated with an acidic oral environment.

Oral complications of cancer therapies. Description and incidence of oral complications

International Nuclear Information System (INIS)

Dreizen, S.

1990-01-01

No part of the body reflects the complications of cancer chemotherapy as visibly and as vividly as the mouth. The infectious, hemorrhagic, cytotoxic, nutritional, and neurologic signs of drug toxicity are reflected in the mouth by changes in the color, character, comfort, and continuity of the mucosa. The stomatologic complications of radiotherapy for oral cancer are physical and physiological in nature, transient or lasting in duration, and reversible or irreversible in type. Some linger as permanent mementos long after the cancer has been destroyed. They stem from radiation injury to the salivary glands, oral mucosa, oral musculature, alveolar bone, and developing teeth. They are expressed clinically by xerostomia, trismus, radiation dermatitis, nutritional stomatitis, and dentofacial malformation. In both cancer chemotherapy and cancer radiotherapy, the oral complications vary in pattern, duration, intensity, and number, with not every patient developing every complication. 21 references

This study, which is motivated by the substantial morbidity of local signs of mucositis and generalized symptoms that result from mucositis induced by therapeutic irradiation, has the following objectives: To investigate if it is possible to prevent irradiation mucositis via oral flora elimination, and, if it is true that flora plays a role in irradiation mucositis, what fraction of the oral flora may be involved; to evaluate oral Gram-negative bacillary carriage; to investigate the possibility to eradicate Gram-negative bacilli from the oral cavity; to evaluate oral yeast carriage; to investigate the possibility to eradicate yeasts stomatitis and the 'selectivity' of elimination of flora. Two methods are described for monitoring alterations of mucositis of the oral cavity and changes in oral flora. Chlorhexidine has been tested as the commonly used prophylaxis. The effect of chlorhexidine 0.1% rinses on oral flora and mucositis has been studied in a prospective placebo controlled double blind randomized programme. The results of the influence of saliva on the antimicrobial activity of chlorhexidine and the results of selective elimination of oral flora in irradiated patients who have head and neck cancer are reported. Salivary inactivation of the topical antimicrobials used for selective elimination of oral flora has been studied and the results are reported. Finally, the objectives that have been achieved (or not) are delineated. The significance of the results of the study are discussed in terms of published information and further lines of research are suggested. (author). 559 refs.; 29 figs.; 20 tabs

To determine the prevalence and clinicopathologic features of the oral cancer patients. Biopsy records of the participating institutions were reviewed for oral cancer cases diagnosed from 2005 to 2014. Demographic data and site of the lesions were collected. Sites of the lesion were subdivided into lip, tongue, floor of the mouth, gingiva, alveolar mucosa, palate, buccal/labial mucosa, maxilla and mandible. Oral cancer was subdivided into 7 categories: epithelial tumors, salivary gland tumors, hematologic tumors, bone tumors, mesenchymal tumors, odontogenic tumors, and others. Data were analyzed by descriptive statistics using SPSS software version 17.0. Of the 474,851 accessioned cases, 6,151 cases (1.30%) were diagnosed in the category of oral cancer. The mean age of the patients was 58.37±15.77 years. A total of 4,238 cases (68.90%) were diagnosed in males, whereas 1911 cases (31.07%) were diagnosed in females. The male-to-female ratio was 2.22:1. The sites of predilection for oral cancer were tongue, labial/buccal mucosa, gingiva, palate, and alveolar mucosa, respectively. The three most common oral cancer in the descending order of frequency were squamous cell carcinoma, non-Hodgkin lymphoma and mucoepidermoid carcinoma. Although the prevalence of oral cancer is not high compared to other entities, oral cancer pose significant mortality and morbidity in the patients, especially when discovered late in the course of the disease. This study highlights some anatomical locations where oral cancers are frequently encountered. As a result, clinicians should pay attention to not only teeth, but oral mucosa especially in the high prevalence area as well since early detection of precancerous lesions or cancers in the early stage increase the chance of patient being cured and greatly reduce the mortality and morbidity. This study also shows some differences between pediatric and elderly oral cancer patients as well as between Asian and non-Asian oral cancer patients.

Interleukin 37 (IL-37) has been reported to play a significant role in innate immune response and to be involved in several kinds of cancers. However, the investigation of association between IL-37 and oral mucosa carcinogenesis hasn't been clearly established. The aim of the study was to assess IL-37 expression and explore its role in oral mucosa carcinogenesis. The expression of IL-37 increased from normal control (NC) to Oral leukoplakia (OLK) and oral squamous cell carcinoma (OSCC). Moreover, statistically highly significant difference was present between scores of OLK with and without mild/moderate dysplasia (P oral mucosa carcinogenesis. Overall, IL-37 can be used as a biomarker for early oral tumorigenesis and for malignant transformation risk assessment of premalignant lesions.

Full Text Available Aim: To compare the efficacy and toxicities of low-dose oral cyclophosphamide and oral etoposide in patients with persistent and recurrent cervical cancer with gross pelvic disease following full course of chemoradiation therapy. Materials and Methods: 30 patients with recurrent and persistent cervical cancer with gross pelvic disease were enrolled in this trial. The patients were randomly divided into two groups of 15 patients each with one group receiving low dose oral cyclophosphamide (100 mg/day and the other group receiving low-dose oral etoposide (50 mg/day. Results were statistically analysed by IBM SPSS Statistics 19. Results: Oral etoposide was not well tolerated with grade 2 neutropenia occurring in 33.3% and grade 3 neutropenia in 6.6% and thrombocytopenia occurring in 13.3%. Oral cyclophosphamide group on the other hand was better tolerated with none of the patients having thrombocytopenia and 6.6% patients having grade 2 neutropenia. There were two complete response (15.38% and one partial response at the end of study (7.6% in the cyclophosphamide group whereas there was no complete response and two partial response (16.6% in the oral etoposide group. Conclusion: Long-term, low-dose oral etoposide was found to be less tolerated without any significant effect with patients with persistent and recurrent cervical cancer with gross pelvic disease following full course of chemoradiation therapy in contrast to oral cyclophosphamide which was found to be effective and well-tolerated by the patients.

This pilot study aimed to investigate the preventive effect of sage tea-thyme-peppermint hydrosol oral rinse used in conjunction with basic oral care on chemotherapy-induced oral mucositis. An open-label randomized controlled study. Two oncology hospitals in Ankara, Turkey. Patients receiving 5-fluorouracil-based chemotherapy regimens were divided into the intervention group (N=30) and control group (N=30). Basic oral care was prescribed to the control group, while the intervention group was prescribed sage tea-thyme-peppermint hydrosol in addition to basic oral care. All patients were called to assess their compliance with the study instructions on day 5 and 14. Oral mucositis was evaluated using an inspection method or by assessing oral cavity photos based on the World Health Organization oral toxicity scale on day 5 and 14. Most of the patients in the intervention group did not develop oral mucositis on day 5. In addition, the incidence of grade 1 oral mucositis was statistically lower in the intervention group (10%) than the control group (53.3%) on day 5. By day 14, the majority of patients in both the groups had grade 0 oral mucositis. Sage tea-thyme-peppermint hydrosol oral rinse has promising results in alleviating oral mucositis. This hydrosol can be recommended for clinical use as it is well tolerated and cost-effective. However, further randomized controlled trials are needed to support the study.

Full Text Available Bitter taste of ofloxacin, a broad spectrum bactericidal agent, is masked and orally disintegrating tablets were formulated. The bitter taste is masked by forming complex between drug and weak cation exchange resins, Tulsion 335 and Indion 204. Effect of pH and drug:resin ratio on the drug loading was studied. Maximum drug loading was observed at pH 6. Ratio of 1:2 of drug:resin masked almost complete bitterness of ofloxacin. Formation of complexes was confirmed by IR spectroscopy. Physical characterization of taste masked complexes was carried out. Present work envisages the taste masking of ofloxacin and development of orally disintegrating tablets. The effect of pH and resin quantities on drug loading were studied to find the optimum conditions of drug loading for complete taste masking. Effect of superdisintegrants like sodium starch glycolate, croscarmellose sodium and polyplasdone XL at varying level on physical parameters of compressed tablets was also assessed.

This study compared the virulence of oral Candida species isolated from human immunodeficiency virus (HIV)-positive women with and without oral candidiasis. Candida species were isolated from 197 women, and their virulence attributes were measured. Of the 197 women, 117 (59.4%) carried Candida. Of these, 15 (12.8%) had symptoms of oral candidiasis. Among highly active antiretroviral therapy (HAART)-naive patients, 33% were diagnosed with oral candidiasis, whereas 5.9% were asymptomatic carriers (P oral candidiasis had higher levels of Candida (P = .02) than asymptomatic carriers. There was no difference in the CD4 counts and the virulence attributes of Candida from both the groups. This study indicates that oral candidiasis is mainly caused by high counts of C. albicans and suggests the importance of therapies targeting Candida counts in the oral cavity even in patients on HAART to reduce the development of infections.

Oral vs. salivary diagnostics

Science.gov (United States)

Marques, Joana; Corby, Patricia M.; Barber, Cheryl A.; Abrams, William R.; Malamud, Daniel

The field of "salivary diagnostics" includes studies utilizing samples obtained from a variety of sources within the oral cavity. These samples include; whole unstimulated saliva, stimulated whole saliva, duct saliva collected directly from the parotid, submandibular/sublingual glands or minor salivary glands, swabs of the buccal mucosa, tongue or tonsils, and gingival crevicular fluid. Many publications state "we collected saliva from subjects" without fully describing the process or source of the oral fluid. Factors that need to be documented in any study include the time of day of the collection, the method used to stimulate and collect the fluid, and how much fluid is being collected and for how long. The handling of the oral fluid during and post-collection is also critical and may include addition of protease or nuclease inhibitors, centrifugation, and cold or frozen storage prior to assay. In an effort to create a standard protocol for determining a biomarker's origin we carried out a pilot study collecting oral fluid from 5 different sites in the mouth and monitoring the concentrations of pro- and anti-inflammatory cytokines detected using MesoScaleDiscovery (MSD) electrochemiluminesence assays. Our data suggested that 3 of the cytokines are primarily derived from the submandibular gland, while 7 of the cytokines come from a source other than the major salivary glands such as the minor salivary glands or cells in the oral mucosae. Here we review the literature on monitoring biomarkers in oral samples and stress the need for determining the blood/saliva ratio when a quantitative determination is needed and suggest that the term oral diagnostic be used if the source of an analyte in the oral cavity is unknown.

Objective: To compare oral submucous fibrosis with other white oral lesions for presentation and associated factors. Study Design: Cross-sectional study. Place and Duration of Study: The Departments of Oral Medicine and Oral and Maxillofacial Surgery, Dr. Ishrat-ul-Ibad Institute of Oral Health Sciences (DIKIOHS), Karachi, from May 2008 to May 2009. Methodology: Patients presenting with oral white lesions were selected by consecutive non-purposive sampling and clinico-demographic data was collected. For patients with oral submucous fibrosis (OSF), additional information like duration of habits, maximal incisal opening (MIO), presence of any other associated lesion were noted. OSF was compared with other white lesions for any association between characteristic of subjects. Chi-square and independent t-tests for determining the statistical significance at p < 0.05. Results: OSF was present in 59.6% (n = 106) of the 178 patients; other white lesions were 40.4% (n = 72). The mean age of patients with OSF was 34 +- 12.7 years and 45.81 +- 16.2 years in patients with other white lesions, (p < 0.0001). Items containing areca nut were consumed more by patients with OSF, with a significant (p < 0.0001) compared to patients with other white lesions. Conclusion: OSF was the predominant white lesion in patients examined at DIKIOHS. Areca nut was found to be chewed more by patients with OSF and still longer by patients with SCC. (author)

The Fungal Biome of the Oral Cavity.

Organisms residing in the oral cavity (oral microbiota) contribute to health and disease, and influence diseases like gingivitis, periodontitis, and oral candidiasis (the most common oral complication of HIV-infection). These organisms are also associated with cancer and other systemic diseases including upper respiratory infections. There is limited knowledge regarding how oral microbes interact together and influence the host immune system. Characterizing the oral microbial community (oral microbiota) in health and disease represents a critical step in gaining insight into various members of this community. While most of the studies characterizing oral microbiota have focused on bacterial community, there are few encouraging studies characterizing the oral mycobiome (the fungal component of the oral microbiota). Our group recently characterized the oral mycobiome in health and disease focusing on HIV. In this chapter we will describe the methods used by our group for characterization of the oral mycobiome.

Visible oral and oropharyngeal premalignant lesions may be used to monitor for a second primary oral cancer. To control for bias, we focused on the visible oral and oropharyngeal premalignant lesions of patients with oral cancer with a positive betel-nut chewing habit. Visible oral and oropharyngeal premalignant lesions that can predict second primary oral cancers were studied. Nine hundred ninety-seven patients with positive betel-nut chewing habits and oral cancer were enrolled in this retrospective cohort study. We analyzed the relevance of their visible oral and oropharyngeal premalignant lesion incidence and relative clinicopathological variables to the development of a second primary oral cancer. Second primary oral cancer risk was significantly higher in patients with positive visible oral and oropharyngeal premalignant lesions (P oral and oropharyngeal premalignant lesions make it a potentially valuable marker in follow-ups of patients with a positive betel-nut chewing habit with oral cancer, especially young patients with heterogeneous leukoplakia. © 2017 Wiley Periodicals, Inc.

To evaluate the effect of oral hygiene care of patients with oral cancer on alleviating acute radiation mucositis. Eighteen patients receiving postoperative radiotherapy for tongue and oral floor cancer were evaluated. Radiotherapy was given in 2 Gy per fraction, 5 times a week for a total dose of 50 Gy in most patients. Radiation field included the tongue and oral floor. During radiotherapy, 8 patients were treated by dento-maxillofacial radiologists with special concern on oral hygiene (oral hygiene group) and the remaining 10 patients were treated with routine dental care (standard medication group). Mucositis were evaluated using JCOG grade and EORTC/RTOG score by radiotherapists or dento-maxillofacial radiologists at 10 Gy intervals. Oral hygiene plans comprised motivation to maintain oral hygiene and establishing the habits of oral self care 4 times per day. Once a week, oral hygiene and oral cleaning of patients were checked by dento-maxillofacial radiologists. Oral self care included mechanical tooth brushing and a chemical mouthwash. No patients with grade 3 and score 4 mucositis were noted in the oral hygiene group. Severe mucositis occurred less frequently in the oral hygiene group than in the standard medication group. Interruption of radiotherapy due to severe mucositis did not occur in the oral hygiene group. On the other hand, interruption of radiotherapy occurred in four patients in the standard medication group, and in three it was due to severe oral pain. Our results suggested that our method of oral hygiene was more effective for alleviating acute radiation mucositis than other methods so far reported. In addition, our method is considered to be useful in preventing rampant dental caries and severe periodontitis due to the xerostomia induced by radiotherapy. (author)

Walicová, Veronika; Gajdziok, Jan

Oral films, namely buccal mucoadhesive films and orodispersible films represent innovative formulations for administration of a wide range of drugs. Oral films show many advantageous properties and are intended for systemic drug delivery or for local treatment of the oral mucosa. In both cases, the film represents a thin layer, which could be intended to adhere to the oral mucosa by means of mucoadhesion; or to rapid dissolution and subsequent swallowing without the need of liquid intake, in the case of orodispersible films. Main constitutive excipients are film-forming polymers, which must in the case of mucoadhesive forms remain on the mucosa within the required time interval. Oral films are currently available on the pharmaceutical market and could compete with conventional oral dosage forms in the future. oral cavity oral films buccal mucoadhesive films orodispersible films film-forming polymers.

Full Text Available There is an escalating demand for geriatric oral healthcare in all developed and developing countries including India. Two-thirds of the world’s elderly live in developing countries. This is a huge population that must receive attention from policy-makers who will be challenged by the changing demands for social and health services including oral health services. Resources are limited thus rather than being aspirational in wanting to provide all treatment needed for everybody, this critique presents a road map of how we might answer the present and future geriatric oral health concerns in a most efficient manner in a developing country. Viewing the recent Indian demographic profile and the trends in oral health, pertinent policy subjects have been discussed concerning the oral health needs of the elderly and also the associated challenges which include strategies to improve quality of life, strategies to train and educate the dental workforce and above all the role of healthcare systems towards realization of better aged society in India and other developing countries

Oral and neck examination for early detection of oral cancer--a practical guide.

LENUS (Irish Health Repository)

MacCarthy, Denise

2011-08-01

Cancer of the head and neck region presents a challenge since, unlike other areas of the body, the boundaries are not always easy to delineate. The functional morbidity associated with head and neck cancer and its treatment are considerable. Head and neck cancer is described as cancer of the lip, mouth, tongue, tonsil, pharynx (unspecified), salivary gland, hypopharynx, larynx and other. Oral cancer refers to cancers of the lip, tongue, gingivae, floor of the mouth, palate (hard and soft), maxilla, vestibule and retromolar area up to the anterior pillar of the fauces (tonsil). When patients present with oral cancer, over 60% of them have regional (lymph node) and sometimes distant (metastatic) spread. The overall five-year survival rates for oral cancer average at between 50 and 80%, depending on the stage of the disease, varying from 86% for stage I to 12-16% for stage IV. The incidence of \\'field cancerisation\\'\\/unstable oral epithelium is high (17%), and even after successful treatment our patients need to be monitored for dental care and further disease. Unlike other areas in the body, the oral epithelium is readily accessible for examination and even self-examination. Dentists and dental hygienists are effective clinicians in the examination of the oral cavity for mouth cancer. An oral and neck examination must be part of every dental examination. An examination protocol is suggested here, which is similar to, but more detailed than, the standardised oral examination method recommended by the World Health Organisation, and consistent with those protocols followed by the Centres for Disease Control and Prevention and the National Institutes of Health.

The present study was undertaken to determine the prevalence of oral hygiene practices, smoking habits and halitosis among undergraduate dental students and correlating the oral hygiene practices, oral health conditions to the prevalence of self perceived oral malodour. A self-administered questionnaire was distributed among 277 male and female students. A questionnaire was developed to assess the self-reported perception of oral breath, awareness of bad breath, timing of bad breath, oral hygiene practices, caries and bleeding gums, dryness of the mouth, smoking and tongue coating. The results indicate female students had better oral hygiene practices. Significantly less self-reported oral bad breath (P = 0.007) was found in female dental students (40%) as compared to their male counterparts (58%). It was found that smoking and dryness of mouth had statistically significant correlation with halitosis (P = 0.026, P = 0.001). Presence of other oral conditions such as tongue coating and dental caries and bleeding gums also showed higher prevalence of halitosis in dental students. A direct correlation exists between oral hygiene practices and oral health conditions with halitosis. Females exhibited better oral hygiene practices and less prevalence of halitosis as compared to male students.

The prevalence of the disease in the general population is about 1-2%. Etiopathogenesis is not still well understood. Histopathology, in addition to the basic methods, anamnesis and physical examination, is vital for proper diagnosis of oral lichen planus (OLP. Very diverse and loaded histological findings are common for all forms of oral lichen planus. We reported the case of oral lichen planus in a 49 years old male patient, who presented to the Dentistry clinic of Medical faculty of Priština with burning and itching symptoms and changes in the buccal mucosa. Histopathological analysis of biopsy tissue conformed clinical diagnosis of lichen planus. Due to the possibility for malignant transformation of lesions, the long-term follow-up of patients with this disease is of great importance.

Oral health during pregnancy.

Silk, Hugh; Douglass, Alan B; Douglass, Joanna M; Silk, Laura

2008-04-15

Oral health care in pregnancy is often avoided and misunderstood by physicians, dentists, and patients. Evidence-based practice guidelines are still being developed. Research suggests that some prenatal oral conditions may have adverse consequences for the child. Periodontitis is associated with preterm birth and low birth weight, and high levels of cariogenic bacteria in mothers can lead to increased dental caries in the infant. Other oral lesions, such as gingivitis and pregnancy tumors, are benign and require only reassurance and monitoring. Every pregnant woman should be screened for oral risks, counseled on proper oral hygiene, and referred for dental treatment when necessary. Dental procedures such as diagnostic radiography, periodontal treatment, restorations, and extractions are safe and are best performed during the second trimester. Xylitol and chlorhexidine may be used as adjuvant therapy for high-risk mothers in the early postpartum period to reduce transmission of cariogenic bacteria to their infants. Appropriate dental care and prevention during pregnancy may reduce poor prenatal outcomes and decrease infant caries.

Good oral health care during pregnancy is essential but often overlooked factor of dental growth as well as of other structures of oral cavity. Pregnancy is the time when conscious approach to preventive oral care should increase. Preventive measures during pregnancy mean usage of fluorides, special dietary measures and increased oral hygiene habits. Preventive measures in pregnant women have one goal: providing conditions for development of fetal teeth as well as preventing tooth decay in pregnant women. The optimal period for introducing preventive measures is the first trimester of pregnancy. Because of hormonal alterations there is an increased incidence of dental diseases: gingivitis and low salivary pH (inflammation and bleeding gums). Eating habits of pregnant women may lead to frequent snacking on candy or other decay-promoting foods, thereby increasing the risk of caries. However, very poor oral health, possible dental complications and their consequences to the health as well as emotional status represent very strong reasons for activation of dental health care in this period.

Analysis of apoptotic cells in oral pathological states could be useful for determining the rates of tissue turnover, which would help determine prognosis. The use of histochemical stains such as hematoxylin and eosin (H & E) and methyl green-pyronin (MGP) can provide a simple and cost-effective method for detecting apoptotic cells. We compared the efficacy of MGP and H & E for detecting apoptotic cells in oral squamous cell carcinoma (OSCC), oral leukoplakia (OL), oral submucous fibrosis (OSMF) and normal oral mucosa (NOM). Ten cases each of OSCC, OSMF, OL and NOM were retrieved from the archives and two serial sections were stained, one with H & E and the other with MGP. Apoptotic cells were identified at 100 x magnification and the apoptotic index was calculated. Apoptotic cells were distinguished more readily in MGP stained sections than in those stained with H & E. Also, the apoptotic cell count was greater in OSCC compared to OL, OSMF and NOM. We concluded that MGP staining can be used as a routine, cost-effective method for detecting apoptotic cells.

To assess the impact of oral hygiene of preschool children and parental attitude on children's oral health-related quality of life (OHRQoL). In this cross-sectional study, 396 children of Shiraz kindergartens were selected by a randomized cluster sampling. Children's oral hygiene was assessed using the Simplified Debris Index (DI-S) and a self-made questionnaire about oral hygiene habits. Children's OHRQoL was evaluated by the Farsi version of Early Childhood Oral Health Impact Scale (F-ECOHIS). The effect of oral hygiene determinants on OHRQoL was measured using Pearson and Spearman correlation, independent-sample t-test and anova. Children's mean DI-S and F-ECOHIS scores were 1.19 (± 0.77) and 19.36 (±8.42), respectively. Only 75% of the children had their teeth brushed once a day or more, and in 28%, toothbrushing had started before 2 years of age. DI-S values (P children. Children's OHRQoL was also significantly associated with parents' attitude towards the importance of brushing deciduous teeth (P = 0.002). Oral health status of preschool children in Shiraz was less than optimal and had a significant impact on their OHRQoL. Therefore, improvement of children's OHRQoL could be achieved by improving their home dental care. Strategies promoting parental attitude about the importance of children's toothbrushing may significantly influence children's oral hygiene and are highly recommended. © 2015 John Wiley & Sons A/S.

The causes of bad breath are numerous and related to conditions dependent or not on oral and general health. The aim of our observational study is the assessment of the simultaneous relationships between halitosis, oral and/or nonoral diseases, and lifestyles using the principal components analysis of categorical data (CATPCA) to identify the main components involved in the detection of the symptom. A sample of 192 patients, who requested general dental examination at the Dental Clinic, participated at the study. Alimentary and voluptuary habits, general health information, drugs assumption, the status of teeth and intraoral medical devices including fillers, lesions of the oral mucosa, tongue coating score (TCS), plaque index (PI), probing bleeding index (PBI) and organoleptic tests were all evaluated. Data were analysed using CATPCA model. A strong relationship between halitosis and plaque, probing bleeding and tongue coating indexes was observed, whereas incongruous fillers, prostheses, systemic pathologies or diet were not clearly associated with halitosis probably because their effects on breath were clinically sheltered by the periodontal condition. The data of our observational study confirm that halitosis is more indicative of tongue coating and periodontal disease, rather than other oral and non oral associated conditions, like systemic pathologies or specific habits of life.

Oral cancer is one of the major global threats to public health. Oral cancer development is a tobacco-related multistep and multifocal process involving field cancerization and carcinogenesis. The rationale for molecular-targeted prevention of oral cancer is promising. Biomarkers of genomic instability, including aneuploidy and allelic imbalance, are able to measure the cancer risk of oral premalignancies. Understanding of the biology of oral carcinogenesis will give us important advances for...

Una vez procesados los datos llegamos a la conclusión que existen sonidos que oralmente solemos pronunciarlos de determinada manera, pero su escritura es de otra. No obstante, los jóvenes no saben discernir entre la oralidad y la escritura y, por desconocimiento de la lengua, escriben igual a como pronuncian. Es tarea del docente reforzar estas habilidades lingüísticas para un mejor desempeño académico y profesional de nuestros estudiantes.Abstract: This article is the result of a research made with a representative sample of 512 students of senior year in the high schools in Costa Rica; in which was used the methodology of lexical availability through surveys, as main objective it has to show that the way of pronunciation influence in writing, therefore, also in orthography. Once the data is process we conclude that there are sounds that orally we used to pronunciation in certain way, but it's writing is different. However, youngest do not know how to distinguish between orally and writing, and, by unknowing the language, they write as they pronounce. It's the teacher's homework to reinforce this linguistic skill for better academic and professional performance of our students.

Background Up to 70% of patients receiving hematopoietic stem cell transplant develop oral mucositis as a side effect of high-dose melphalan conditioning chemotherapy. Oral cryotherapy has been documented to be potentially effective in reducing oral mucositis. The aim of this study was to examine the effectiveness of the cryotherapy protocol implemented within the hematopoietic stem cell transplant program. Methods A retrospective chart review was conducted of adult multiple myeloma patients who received high-dose melphalan conditioning therapy for autologous hematopoietic stem cell transplant. Primary endpoints were incidence and severity of oral mucositis. Secondary endpoints included duration of oral mucositis, duration of hospital stay, parenteral narcotics use and total parenteral nutrition use. Results One hundred and forty patients were included in the study, 70 patients in both no cryotherapy and cryotherapy groups. Both oral mucositis incidence and severity were found to be significantly lower in the cryotherapy group. Fifty (71.4%) experienced mucositis post cryotherapy compared to 67 (95.7%) in the no cryotherapy group (p cryotherapy group (p = 0.03). Oral mucositis duration and use of parenteral narcotics were also significantly reduced. Duration of hospital stay and use of parenteral nutrition were similar between the two groups. Conclusion The cryotherapy protocol resulted in a significantly lower incidence and severity of oral mucositis. These results provide evidence for the continued use of oral cryotherapy, an inexpensive and generally well-tolerated practice.

Full Text Available Ronald C Hamdy,1,2 Dane N Daley11Osteoporosis Center, College of Medicine, East Tennessee State University, 2Veterans Affairs Medical Center, Johnson City, TN, USAAbstract: Calcitonin is a hormone secreted by the C-cells of the thyroid gland in response to elevations of the plasma calcium level. It reduces bone resorption by inhibiting mature active osteoclasts and increases renal calcium excretion. It is used in the management of postmenopausal osteoporosis, Paget's disease of bone, and malignancy-associated hypercalcemia. Synthetic and recombinant calcitonin preparations are available; both have similar pharmacokinetic and pharmacodynamic profiles. As calcitonin is a peptide, the traditional method of administration has been parenteral or intranasal. This hinders its clinical use: adherence with therapy is notoriously low, and withdrawal from clinical trials has been problematic. An oral formulation would be more attractive, practical, and convenient to patients. In addition to its effect on active osteoclasts and renal tubules, calcitonin has an analgesic action, possibly mediated through β-endorphins and the central modulation of pain perception. It also exerts a protective action on cartilage and may be useful in the management of osteoarthritis and possibly rheumatoid arthritis. Oral formulations of calcitonin have been developed using different techniques. The most studied involves drug-delivery carriers such as Eligen® 8-(N-2hydroxy-5-chloro-benzoyl-amino-caprylic acid (5-CNAC (Emisphere Technologies, Cedar Knolls, NJ. Several factors affect the bioavailability and efficacy of orally administered calcitonin, including amount of water used to take the tablet, time of day the tablet is taken, and proximity to intake of a meal. Preliminary results looked promising. Unfortunately, in two Phase III studies, oral calcitonin (0.8 mg with 200 mg 5-CNAC, once a day for postmenopausal osteoporosis and twice a day for osteoarthritis failed to

Poor oral health has been associated with systemic diseases, morbidity and mortality. Many patients in hospital environments are physically compromised and rely upon awareness and assistance from health professionals for the maintenance or improvement of their oral health. This study aimed to identify whether common individual and environment factors associated with hospitalisation impacted on oral hygiene. Data were collected during point prevalence audits of patients in the acute and rehabilitation environments on three separate occasions. Data included demographic information, plaque score, presence of dental hygiene products, independence level and whether nurse assistance was documented in the health record. Data were collected for 199 patients. A higher plaque score was associated with not having a toothbrush (p = 0.002), being male (p = 0.007), being acutely unwell (p = 0.025) and requiring nursing assistance for oral hygiene (p = 0.002). There was fair agreement between the documentation of requiring assistance for oral care and the patient independently able to perform oral hygiene (ICC = 0.22). Oral hygiene was impacted by factors arising from hospitalisation, for those without a toothbrush and male patients of acute wards. Establishment of practices that increase awareness and promote good oral health should be prioritised. © 2015 Nordic College of Caring Science.

Full Text Available The safe and effective treatment of uncooperative or combative preschool children with extensive dental needs is one of pediatric dentist′s ongoing challenges. The traditional methods of behavior management are no longer acceptable to parents as they are not ready to spare more time for dental treatment of their children. Keeping this in mind, the present study was designed and carried out to evaluate the sedative effects of oral ketamine and oral midazolam prior to general anesthesia. Twenty uncooperative children in the age-group of 2-6 years were selected after thorough medical examination and investigations. Informed consent was obtained from the parent. This was a randomized double-blind study. An anesthesiologist administered either 0.5 mg/kg midazolam or 5 mg/kg ketamine orally. The heart rate, respiratory rate, and oxygen saturation were recorded at regular intervals. The sedation and anxiolysis scores were also recorded. The parents were asked to answer a questionnaire at the follow-up session the next day on the surgical experience of the parent and the child and side effects experienced, if any. When the data was subjected to statistical analysis, it was observed that both drugs resulted in adequate sedation at the end of 30 min, with oral midazolam providing significantly better anxiolysis. The heart rate and respiratory rate were marginally higher with oral ketamine. The questionnaire revealed a better response with oral midazolam; side effects were more prominent with oral ketamine.

We aimed to compare oral hygiene habits, orodental status, and dental procedures in patients with infective endocarditis (IE) according to whether the IE-causing microorganism originated in the oral cavity. We conducted an assessor-blinded case-control study in 6 French tertiary-care hospitals. Oral hygiene habits were recorded using a self-administered questionnaire. Orodental status was analyzed by trained dental practitioners blinded to the microorganism, using standardized clinical examination and dental panoramic tomography. History of dental procedures was obtained through patient and dentist interviews. Microorganisms were categorized as oral streptococci or nonoral pathogens using an expert-validated list kept confidential during the course of the study. Cases and controls had definite IE caused either by oral streptococci or nonoral pathogens, respectively. Participants were enrolled between May 2008 and January 2013. Cases (n = 73) were more likely than controls (n = 192) to be aged calculus, and infectious dental diseases did not significantly differ between groups. Patients with IE caused by oral streptococci differ from patients with IE caused by nonoral pathogens regarding background characteristics, oral hygiene habits, and recent dental procedures, but not current orodental status. © The Author 2017.

Objective: To evaluate the influence of oral hygiene on risk of oral cancer in non-smoking and non-drinking women. Methods: From September 2010 to February 2016, 242 non-smoking and non-drinking female patients with pathologically confirmed oral cancer were recruited in a hospital of Fuzhou, and another 856 non-smoking and non-drinking healthy women from health examination center in the same hospital were selected as control group. Five oral hygiene related variables including the frequency of teeth brushing, number of teeth lost, poor prosthesis, regular dental visits and recurrent dental ulceration were used to develop oral hygiene index model. Unconditional logistic regression was used to calculate odds ratios ( OR ) and 95% confidence intervals (95 %CI ). The area under the receiver operating characteristic curve (AUROC) was used to evaluate the predictability of the oral hygiene index model. Multivariate logistic regression model was used to analyze the association between oral hygiene index and the incidence of oral cancer. Results: Teeth brushing oral cancer in non-smoking and non-drinking women, the corresponding OR (95 %CI ) were 1.50 (1.08-2.09), 1.81 (1.15-2.85), 1.51 (1.03-2.23), 1.73 (1.15-2.59), 7.30 (4.00-13.30), respectively. The AUROC of the oral hygiene index model was 0.705 9, indicating a high predictability. Multivariate logistic regression showed that the oral hygiene index was associated with risk of oral cancer. The higher the score, the higher risk was observed. The corresponding OR (95 %CI ) of oral hygiene index scores (score 1, score 2, score 3, score 4-5) were 2.51 (0.84-7.53), 4.68 (1.59-13.71), 6.47 (2.18-19.25), 15.29 (5.08-45.99), respectively. Conclusion: Oral hygiene could influence the incidence of oral cancer in non-smoking and non-drinking women, and oral hygiene index has a certain significance in assessing the combined effects of oral hygiene.

Adequate dental and oral hygiene may become a challenge for all users and especially for elderly people and young children because of their limited motor skills. The same holds true for patients undergoing/recovering from chemo-/radiotherapy with accompanying sensitive mucosal conditions. Poor dental hygiene can result in tooth decay, gingivitis, periodontitis, tooth loss, bad breath (halitosis), fungal infection and gum diseases. The use of a toothbrush is the most important measure for oral hygiene. Toothbrushes with soft bristles operated carefully by hand or via an electric device help to remove plaque and to avoid mucosal trauma. A handlebar with a grip cover can be helpful for manually disabled patients or for those with reduced motor skills. In case of oral hygiene at the bedside or of patients during/after chemo-/radiotherapy a gauze pad can be helpful for gently cleaning the teeth, gums and tongue. The use of fluoride toothpaste is imperative for the daily oral hygiene. Detergents such as sodium lauryl sulphate improve the cleaning action but may also dehydrate and irritate the mucous membrane. The use of products containing detergents and flavouring agents (peppermint, menthol, cinnamon) should therefore be avoided by bedridden patients or those with dry mouth and sensitive mucosa. Aids for suitable interdental cleaning, such as dental floss, interdental brushes or dental sticks, are often complicated to operate. Their correct use should be instructed by healthcare professionals. To support dental care, additional fluoridation with a fluoride gel or rinse can be useful. Products further containing antiseptics such as chlorhexidine or triclosan reduce the quantity of bacteria in the mouth. For patients undergoing or having undergone radio-/chemotherapy, a mouthwash that concomitantly moisturizes the oral mucosa is advisable. Copyright © 2011 S. Karger AG, Basel.

Fenproporex hydrochloride (FEN) is an anorectic drug used in the treatment of obesity, and its major metabolite is amphetamine (AMP), another central nervous system stimulant. The concentration versus time profile of FEN and its metabolite AMP has been described in classic biological matrices such as plasma and urine; however, there are no reports of such data in oral fluid. The aim of this study is to describe the pharmacokinetics of FEN and AMP in oral fluid after intake of FEN. Twenty-five milligrams of FEN (1 capsule of Desobesi-m) was orally administered to 6 male volunteers, and oral fluid samples were collected with a Quantisal device during 24.00 hours after drug ingestion. These samples were submitted to solid-phase microextraction before analysis by gas chromatography-mass spectrometry in the selected-ion-monitoring mode, using deuterium-labeled AMP as internal standard. After FEN administration, both analytes could be detected in oral fluid of all volunteers with an initial detection time varying from 0.50 to 1.00 hour. FEN peak concentrations occurred between 1.00 and 1.50 hours after administration and were between 70.7 and 227.5 μg/L. For AMP, peak concentration occurred between 1.50 and 4.00 hours, reaching 33.0-150.9 μg/L. The authors observed that oral administration of FEN resulted in significant amounts of FEN and AMP in oral fluid, showing that oral fluid could be a biological matrix suitable for pharmacokinetic studies for both analytes. Using a compartmental approach, FEN data were best fitted by 1-compartment model with first-order input and output, whereas AMP followed a 2-compartment model with first-order input and output.

Ecological therapeutic opportunities for oral diseases

SUMMARY The three main oral diseases of humans, that is caries, periodontal diseases and oral candidiasis, are associated with microbiome shifts initiated by changes in the oral environment and/or decreased effectiveness of mucosal immune surveillance. In this review we discuss the role that microbial-based therapies may have in the control of these conditions. Most investigations on the use of microorganisms for management of oral disease have been conducted with probiotic strains with some positive but very discrete clinical outcomes. Other strategies such as whole oral microbiome transplantation or modification of community function by enrichment with health-promoting indigenous oral strains may offer more promise but research in this field is still in its infancy. Any microbial-based therapeutics for oral conditions, however, are likely to be only one component within a holistic preventive strategy that should also aim at modification of the environmental influences responsible for the initiation and perpetuation of microbiome shifts associated with oral dysbiosis.

Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

Two Unusual Cases of Oral Lichen Planus Arising After Oral Squamous Cell Carcinoma: Can Oral Cancer Trigger Autoimmunity?

Science.gov (United States)

Gissi, Davide Bartolomeo; Asioli, Sofia; Gabusi, Andrea

2017-08-01

Autoimmune diseases occur when the immune system fails to recognize self-antigens expressed on the body's own cells and attacks them. Oral lichen planus (OLP) is a chronic autoimmune mucocutaneous disease of the oral cavity characterized by white/red lesions. Considered a potentially malignant disorder, OLP evolution into oral squamous cell carcinoma (OSCC) is still a matter of debate. While chronic autoimmune inflammation is considered a potential risk factor for malignant transformation in many solid tumors, the opposite idea that cancer may trigger autoimmune responses remains controversial. We describe 2 patients who developed lesions clinically suggestive of OLP with histological evidence of lichenoid infiltration some time after OSCC removal, even in areas far from the neoplastic site. Neither patient had OLP before the diagnosis of OSCC, or reported exposure to OLP-associated etiologic factors, and neither. experienced tumor recurrence during follow-up. Our findings suggest that oral cancer remission may be linked to OLP development, but further studies are necessary to unveil the underlying mechanisms and possible prognostic implications.
