The Elderly, Carriers of Dementia Syndromes and Dental Care

The demographic and epidemiological transition resulting from declining birth rates, increased economically active population, decreased infectious diseases and increased chronic degenerative diseases produce a population scenario with a high number of elderly individuals, prone to developing dementia, whose prevalence is directly related to increasing age. Dementia is progressive and characterized by the loss of self-care ability and ability to perform activities of daily living, including the difficulty to perform oral hygiene and accept dental treatment, thus resulting in decreased oral health. Thus, it is necessary to know and think about oral care to increase the quality of life of this population through actions of health promotion, prevention and recovery with the accomplishment of home and hospital dental procedures, besides the traditional service, at a dental office

Doenças peri-implantares: atualização para odontologia

Objective: this study aims to present and describe the main pathological, benign and malignant alterations of the peri-implant mucosa. Material and Methods: an integrative review of the literature was carried out using the following descriptors: peri-implant pathology; reactive lesion dental implant; carcinoma dental implant; peri-implant disease dental implant; reactive lesion by dental implant; oral squamous cell carcinoma around dental implants; peri-implant disease; pathology; for the elaboration of the search strategy in the databases PubMed, LILACS, MEDLINE and SciElo to obtain the scientific productions. Results: conditions such as peri-implant mucositis and peri-implantitis are poorly reported in the literature, which makes it difficult to estimate their real prevalence. Among the benign reactive lesions, the pyogenic granuloma and peripheral giant-cell granuloma stand out, described as the most frequently associated with the implants. Regarding neoplasia, cases of hemangioma and OSCC were published, suggesting a possible influence of the implant in the development of these conditions. Conclusion: the occurrence of several pathologies associated with dental implants was observed in the literature, which demonstrates the importance of a detailed clinical examination, associated, in certain situations, with histopathological examination for an accurate diagnosis and adequate management of the various peri-implant diseases.Objetivo: este estudo tem como objetivo apresentar e descrever as principais alterações patológicas, benignas e malignas da mucosa peri-implantar. Material e Métodos: uma revisão integrativa da literatura foi realizada utilizando os seguintes descritores: patologia peri-implantar; implante dentário de lesão reativa; implante dentário de carcinoma; implante dentário de doença peri-implantar; lesão reativa por implante dentário; carcinoma oral de células escamosas ao redor de implantes dentários; doença peri-implantar; patologia; para a elaboração da estratégia de busca nas bases de dados PubMed, LILACS, MEDLINE e SciElo para obtenção das produções científicas. Resultados: condições como mucosite peri-implantar e peri-implantite são pouco relatadas na literatura, o que dificulta a estimativa de sua real prevalência. Dentre as lesões reativas benignas, destacam-se o granuloma piogênico e o granuloma periférico de células gigantes, descritos como os mais frequentemente associados aos implantes. Em relação à neoplasia, foram publicados casos de hemangioma e CECO, sugerindo uma possível influência do implante no desenvolvimento dessas condições. Conclusão: a ocorrência de diversas patologias associadas a implantes dentários foi observada na literatura, o que demonstra a importância de um exame clínico detalhado, associado, em determinadas situações, a exame histopatológico para um diagnóstico acurado e manejo adequado das diversas doenças peri-implantare

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
