Revisão de literatura de Leucoplasia Oral

Similar a outras lesões de pele, têm sido identificadas lesões precursoras de carcinoma de células escamosas na mucosa da cavidade oral. Na boca, apresenta-se frequentemente em forma de placa branca, denominada leucoplasia. Na conferência de 2005, a leucoplasia foi definida pela OMS como “uma placa ou mancha branca que não pode ser caracterizada clínica ou patologicamente como qualquer outra doença.” Leucoplasia é, portanto, um diagnóstico clínico de exclusão. A frequência de apresentar displasia epitelial, carcinoma in situ, carcinoma verrucoso ou carcinoma de células de escomosas invasivo na leucoplasia oral varia de 8,6% a 60%. A transformação maligna anual de leucoplasia é de 1% a 5 %. Sendo assim, é de fundamental importância, por parte dos profissionais na saúde e principalmente dos médicos dentistas terem conhecimento da leucoplasia oral para que possam suspeitar, fazer o diagnóstico ou encaminhar a profissionais competentes precocemente para o manejamento dessas lesões.

Cimentos convencionais e adesivos na cimentação final em prótese fixa

Os cimentos dentários na função de preencher a interface entre a superfície dentária e superfície interna da prótese nos coloca frente a uma diversidade de substratos e técnicas. O presente trabalho visou rever conceitos associados aos cimentos dentários, a evolução destes materiais junto aos diferentes sistemas cerâmicos e suas limitações no seu universo bem como a estratégia da sua aplicação em superfícies resistentes ou não ao ácido condicionante. Para alcançar a resposta de qual o melhor método na escolha de um material para cimentação de próteses fixas, este trabalho também apresenta uma comparação entre os cimentos dentários convencionais e resinosos. Este trabalho consiste numa revisão bibliográfica de forma a pesquisar de forma geral os cimentos de uso na medicina dentária. Foi realizada uma pesquisa, em abril de 2016, nas bases de dados da PubMed e B-on e em obras de caráter científico com o intuito de recolher informações sobre o assunto em um intervalo temporal de 10 anos. Os critérios escolhidos foram casos clínicos, revisão de literatura e estudos in vitro, segundo o seu rigor científico e interesse para o tema. O resultado sobre os testes de resistência utilizados nos estudos, os testes de aderência do cimento ao dente podem variar amplamente. O tratamento de superfícies e a evolução tecnológica podem ser eficazes na escolha desses materiais, bem como a comparação dos tipos de falhas que ocorrem na interface adesivas. A conclusão que se obteve é que os materiais raramente são comparados com um padrão e muitas vezes as condições experimentais variam.

Promoting oral health in adults with learning disability

Introduction: It is complex to define learning disabilities, there is no single universal definition used; there are different interpretations and definitions used for learning disabilities in different countries and communities. Primarily, the term “learning disability” sometimes used as “learning difficulties” is a term widely used in UK. There are various types and degree of severity of learning disabilities depending upon the extent of disorder. Though different definitions used all over the world, its types and classification coupled with their health and oral health needs are discussed in this review. Objectives:  To review the background literature on definitions of learning disabilities and health needs of this population.  To review literature on individual clinical preventive intervention to determine the effectiveness in promoting oral health amongst adults in learning disabilities.  To review literature in relation to community based preventive dental measures.  To determine the interventions in this areas are appropriate to support policy and practice and if these interventions establish good evidence to suggest that the oral health needs of adults with learning disabilities are met or not.  To make recommendations in implementing future preventive oral health interventions for adults with learning disabilities. Methodology: It was develop a comprehensive narrative synthesis of previously published literature from different sources and summarizes the whole research in a particular area identifying gap of knowledge. It provides a broad perspective of a subject and supports continuing education. It also is directed to inform policy and further research. It is a qualitative type of research with a broad question and critical analysis of literature published in books, article and journals. The research question evaluated on PICOS criteria is: Effectiveness of preventive dental interventions in adults with learning disabilities. The research question clearly defines the PICOS i.e. participants, interventions, comparison, outcome and study design. The Cochrane database of systematic reviews (CDSR), Database of Abstracts of Reviews of effects (DARE) through York University and National institute of Health and Clinical Excellence (NICE) was searched to identify need of this review. There was no literature review found on the preventive dental interventions found hence, justifying this review. The guidance used in this review is from York University and methods opted for search of literature is based on the following: Type of participants, interventions, outcome measure, studies and search. The review of literature; author search; systematic and narrative reviews, through the following electronic databases via UFP library services: Pub-Med, Medline, EMBASE, CINHAL, Google scholar; Science Direct; Social and Medicine. A comprehensive search of all available literature from 1990-2015, including systematic reviews, policy documents and some guideline documents was done. Internet resource used to access; Department of Health, World Health Organization, Disability World, Disability Rights Commission, the Stationery office, MENCAP, Australian Learning Disability Association. The literature search was carried out with single word, combined words and phrases, authors' names and the title of literature search. Results: It is primarily looking at the oral health interventions available for adults with learning disabilities in clinical settings and the community measures observed over a period of 25 years 1990-2015. There were 7of the clinical intervention studies and one community based intervention study was added in this review. Conclusion: There is a gap of knowledge identified in not having ample research in the area of preventive dental interventions in adults with learning or intellectual disabilities and there is a need of more research, studies need to be of a better quality and a special consideration is required in the community settings where maintenance of oral hygiene for this vulnerable group of society is hugely dependent on their caregivers. Though, the policy and guideline directs on the preventive dental interventions of adults with LD there still a gap evident in understanding and implication of the guidance in practice by the dental and care support team. Understanding learning disabilities and to identify their behavior, compliance and oral health needs is paramount for all professionals working with or for them at each level.
