Peri-implantite

Introdução: A colocação de implantes dentários tornou-se um procedimento de rotina para a reabilitação de pacientes parcial ou totalmente desdentados. As doenças periimplantares constam atualmente como uma importante complicação biológica. Sendo as doenças periimplantares de origem infeciosa, podem ser classificadas em mucosite periimplantar, uma condição caracterizada por uma inflamação reversível e sem perda de suporte ósseo, e em peri-implantite, que é uma inflamação irreversível que afeta o osso de suporte em implantes osteointegrados. Ao longo dos últimos anos diferentes estratégias de tratamento para a peri-implantite têm sido sugeridas, no entanto, continua por estabelecer qual a abordagem terapêutica mais eficaz. Objetivo: Realizar uma revisão narrativa sobre as doenças periimplantares, abordando os aspetos epidemiológicos, a etiologia, o diagnóstico e avaliar, de entre as diferentes abordagens terapêuticas disponíveis para o tratamento da peri-implantite, qual ou quais as mais efetivas. Matérias e Métodos: Foi realizada uma pesquisa bibliográfica recorrendo à base de dados da “MEDLINE/Pubmed”, com as seguintes palavras e expressões-chave: “Peri-implantitis and Diagnosis”, “Peri-implantitis and Treatment”. Deu-se especial ênfase a revisões sistemáticas e a meta-análises. Apenas foram pesquisados artigos em inglês, não tendo sido empregues quaisquer limites temporais. Conclusão: Sendo as doenças periimplantares bastante frequentes, é da responsabilidade do clinico examinar e monitorizar os pacientes que foram reabilitados com implantes. O clinico deve informar sobre as complicações biológicas e a necessidade das consultas de manutenção. Atualmente não existe nenhum protocolo ideal estabelecido para o tratamento da peri-implantite. Nesse sentido, a prevenção da doença é fundamental.

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.

Socket-shield and immediate implantation

Introduction - After tooth extraction, the alveolar bone undergoes a remodeling process, wich leads to horizontal and vertical bone loss. These resorption processes complicate dental rehabilitation, particularly in connection with implants. Various methods of guided bone regeneration have been described to retain the original dimension of the bone after extraction. Most procedures use filler materials and membranes to support the buccal plate and soft tissue, to stabilize the coagulum and to prevent epithelial ingrowth. It has also been suggested that resorption of the buccal bundle bone can be avoided by leaving a buccal root segment (socket-shield technique) in place, because the biological integrity of the buccal periodontum remains untouched. This method has also been decribed in connection with immediate implant placement. Objective - This literature review aim enumerate and describe the different treatments and tissue reactions after tooth extraction, immediate and delayed implantation. The socketshield technique, the evolution in tooth extraction and immediate implantation with high esthetic results due to the preservation of hard and soft tissues by leaving a buccal root segment in place. Materials and methods - For this purpose a research has been done and data was obtained from on-line resources: Medline, Pubmed, Scielo, Bireme, Bon, books and specialized magazines which was conducted between January 2016 and May 2016. A number of articles have been obtained in English and French ,published between 1997 and 2015 . The key words used were implantology, dental implant, hard/soft tissue, tooth extraction, immediate implantation, delayed implantation, socket-shield. Conclusion - In socket-shield technique, there were neither functional nor aesthetic changes in soft and hard tissues. It’s already a routine practice in the arsenal of highaesthetic immediate implantology and should be used when indicated. Although this technique is quiet promising, we should be aware of the incoming publications about a larger follow up and the predictability of leaving a fragment inside the socket after an extraction.
