    As cerâmicas de zircônia tetragonal policristalina estabilizada por ítrio (Y-TZP) apresentam propriedades mecânicas como alta resistência e tenacidade à fratura superiores às das demais cerâmicas odontológicas. Entretanto, o aumento do conteúdo cristalino modificou suas características de adesão a cimentos resinosos, tornando necessário o desenvolvimento de métodos mais efetivos de união a estes materiais. Estudos têm sugerido técnicas de cimentação específicas para cerâmicas Y-TZP que incluem métodos de tratamento da superfície para alcançar uma condição satisfatória de adesão da zircônia aos cimentos resinosos. O presente trabalho traz uma revisão da literatura acerca das diferentes técnicas de tratamento de superfície de coroas protéticas de cerâmicas de zircônia tetragonal policristalina estabilizada por ítrio (Y-TZP). As pesquisas mostram que ainda não há um protocolo definido de cimentação, contudo os resultados apontam para uma associação de métodos para que a união adesiva seja obtida e que a silicatização e o jateamento com óxido de alumina foram os métodos mais investigados apresentando bons resultados quando associados com um agente químico de união

    Introduction: Coronavirus disease (Covid-19) is an infectious disease affecting the respiratory tract, which emerged in China and spread rapidly throughout the world. Objective: To evaluate the methodological quality and transparency of Brazilian clinical practice guidelines for the treatment of coronavirus disease (Covid-19). Materials and Methods: A systematic review was conducted in 2020 on Medline (via PubMed), Embase, Scopus, LILACS, National Guideline Clearinghouse and Guidelines International Network databases, in addition to online searches on the Brazilian Ministry of Health, Brazilian Medical Association, Federal Council of Medicine, Federal Council of Nursing and Federal Council of Physical Therapy websites. The methodological quality and transparency of the guidelines were assessed using the second version of the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument developed by four authors. Results: 33 guidelines were found of which 14 were included in the analysis. There was only one guideline that scored above 60% in all domains. Among the six domains, higher scores were found in the following three domains: scope and objective, stakeholder involvement and clarity of presentation. Discussion: Despite methodological weakness found, the authors were keen to provide clear and concise recommendations through key information and therapeutic options to facilitate decision making. Conclusions: Brazilian clinical practice guidelines were found to be of poor methodological quality, from which only one guideline was recommended and classified as to be of high methodological quality and transparency.

Diretrizes de prática clínica para o tratamento da Covid-19 no Brasil: uma revisão sistemática. Revista Cuidarte. 2021;12(2):e2025 http://dx.doi.org/10.15649/cuidarte.2025   Introdução: A Coronavirus Disease-2019 é uma doença infectocontagiosa que afeta o sistema respiratório, que surgiu na China e logo se espalhou pelo mundo. Objetivo: Avaliar a qualidade metodológica e transparência das Diretrizes de Prática Clínica brasileiras para o tratamento da Coronavirus Disease-2019. Materiais e Métodos: Trata-se de uma revisão sistemática realizada em 2020 nas fontes de dados: MEDLINE (via PubMed), EMBASE, Scopus e Literatura Latino-Americana e do Caribe em Ciências da Saúde, National Guideline Clearinghouse e Guidelines International Network, e sites do Ministério da Saúde do Brasil, Sociedades Médicas Brasileiras, Conselhos de Medicina, Conselho Federal de Enfermagem e Conselho Federal de Fisioterapia. A avaliação da qualidade metodológica e da transparência das diretrizes ocorreu por meio do instrumento Appraisal of Guidelines for Research & Evaluation, versão II, realizada por quatro autores. Resultados: Foram encontradas 33 diretrizes, das quais foram incluídas 14 para análise. Somente uma diretriz apresentou pontuações acima de 60% em todos os domínios. Entre os seis domínios, três apresentaram maiores pontuações: Escopo e finalidade, Envolvimento das partes interessadas e Clareza da apresentação.  Discussão: Apesar da fragilidade metodológica, os autores se preocuparam em apresentar as recomendações de forma clara e concisa, através de informações-chave e opções terapêuticas que facilitam a tomada de decisão. Conclusão: As diretrizes brasileiras apresentaram baixa qualidade metodológica, em que somente uma diretriz foi recomendada e classificada com alta qualidade e transparência metodológica.   Como citar este artigo: Lanes, Taís Carpes; Ribeiro, Mariane Albuquerque Lima; Oliveira, Daianny Seoni de; Junior, Marcos Gabriel do Nascimento; Garcia, Filipe Reis; Melo, Jéssyca Maria França de Oliveira; Tiguman, Gustavo Magno Baldin.

    Implant- and tooth-supported removable partial dentures: a case report

    No full text
    ABSTRACT This study aimed to report treatment of a patient with Kennedy’s class l maxillary and class II mandibular arch with removable partial dentures supported on an external hexagon (HE) anterior type implant of regular diameter fitted with an O’ring type of attachment. This clinical case reports the oral rehabilitation of a senile patient whose clinical examination revealed missing dentition in the upper and lower arches, attrition of the lower anterior teeth, caries, and motor impairment affecting hygiene, mastication, and esthetic functions. Due to few severely impaired teeth, the pre-prosthetic preparation included extractions and restorations, followed by the fabrication of upper and lower removable partial dentures supported by an HE-type implant. This study is important because it addresses the current challenges faced in the implementation of treatment involving removable partial dentures combined with implants, which is a topic that still needs long-term follow-up and research

    ABSTRACT The single-stranded ribonucleic acid coronavirus is the seventh known member of the Coronaviridae family to infect humans. The droplets and aerosols that are suspended in the air with the virus can be transmitted by contact with the oral, nasal and eye mucosa, which can cause severe acute respiratory syndrome. Due to the outbreak of the new coronavirus disease, the constant use of personal protective equipment by health professionals has become necessary, as the virus has a rapid and widespread spread. But, unexpectedly, the coronavirus outbreak brought another concern, the emergence of facial injuries due to the continuous and inappropriate use of these individual protectors, harming the health of these professionals. An alternative to alleviate and prevent such injuries would be the use of prophylactic creams and dressings in places where there is pressure caused by these equipment, as well as relieving the loads generated by them, at intervals that do not exceed 4 hours. Therefore, this literature review aimed to report the potential for the emergence of facial injuries caused by the continuous and inappropriate use of PPE, highlighting the most affected areas, the risks to the health of the professional, prevention and treatment, through the electronic consultation based on of data, PUBMED, SCOPUS and Bireme/BVS

    No full text
    ABSTRACT The fast spread of COVID-19 around the world has generated significant impacts on the way societies lives, one of which is the scarcity of personal protective equipment (PPE) for workers in the front lines of combat against the virus. Sanitary insecurity has led populations and health professionals to a rampant search for protective equipment and other devices necessary for life maintenance, both for patients and professionals, revealing health system limitations during large-scale crisis, as the COVID-19 pandemic. On this paper, we aimed to present the initiatives of professionals and companies related to 3D printing to share programs and resources whose purpose is supplying workers in the front line, who have been important allies in combating the effects caused by coronavirus. A search was performed in four electronic databases: SCOPUS, BVS, EMBASE and MEDLINE via PUBMED. After analyzing the inclusion and exclusion criteria, a table of results was prepared with the main characteristics of the products manufactured and made available, as well as the institutions involved. It was concluded, therefore, that the applications of 3D printing in the initiatives had great contributions to public health and the additive industry during the pandemic period of COVID-19
