Anatomy alive
A Anatomia Humana é um conteúdo indispensável na matriz curricular de cursos da área da saúde, sendo crescente a demanda no ensino superior por novas tecnologias que possam ajudar no processo de seu estudo. Assim, objetivou-se desenvolver e validar, quanto ao conteúdo e usabilidade, um aplicativo móvel para apoio ao ensino-aprendizagem de Anatomia de Cabeça e Pescoço aplicada à Odontologia. O estudo foi desenvolvido em cinco etapas: (1) definição do escopo e registro de marca, (2) preparação de peças anatômicas, (3) desenvolvimento do protótipo, (4) avaliação de conteúdo e (5) avaliação de usabilidade e grau de satisfação. Para avaliação de conteúdo, 5 docentes/juízes, com expertise na área de Anatomia Humana, responderam a um questionário online contendo 8 perguntas relacionadas ao conteúdo e funcionalidade do protótipo. A usabilidade foi avaliada por 15 estudantes de graduação em Odontologia, por meio da versão brasileira da escala System Usability Scale (SUS) e uma escala visual analógica de 0-10 pontos para satisfação. A equipe desenvolveu um aplicativo híbrido, compatível com o sistema operacional Android, permitindo a identificação de estruturas anatômicas em peças cadavéricas reais e testes de conhecimento a partir de questões objetivas. A pontuação média da avaliação dos juízes foi de 9,6, indicando conteúdo e funcionalidade adequados. O escore final da escala SUS foi 90,33 (usabilidade excelente) e a média de satisfação dos usuários foi 9,13. Conclui-se que o aplicativo apresentou compatibilidade, conteúdo, funcionalidade e usabilidade adequados, podendo ser usado como um recurso gratuito para apoio ao ensino-aprendizagem de Anatomia de Cabeça e Pescoço.

O tratamento de feridas cutâneas com ultrassom terapêutico é eficaz? Análise e proposta de um protocolo experimental
No Brasil, as feridas constituem um sério problema de saúde pública, devido ao grande número de doentes com alterações na integridade da pele, embora sejam escassos os registros desses atendimentos. Na tentativa de minimizar o tempo de cicatrização tecidual, diversos estudos com animais vêm apresentando como fator coadjuvante a utilização do ultrassom terapêutico. Entretanto, não há padronização das doses para utilização dessa terapia em feridas cutâneas. Propor um protocolo para avaliar a eficácia no tratamento de feridas cutâneas experimentais por meio de ultrassom terapêutico pulsado de 3 MHz através de 1,0W/cm2, 1,5W/cm2, 2,0W/cm2. Trata-se de um estudo experimental e randomizado. Foram utilizados 60 ratos Wistar, machos, adultos. Após anestesiados, os animais foram submetidos a cirurgia para retirada de um fragmento da pele na região do dorso do animal com a utilização de punch dermatológico no 8. Os animais foram randomizados aleatoriamente em 4 grupos diferentes sendo eles: grupo controle; GA (1,0w/cm2); GB (1,5w/cm2) e GC (2,0w/cm2). O aparelho foi fixado nos demais parâmetros: 3MHz, pulsado com 20% largura de pulso, 100Hz, por 2 minutos. O tratamento foi realizado diariamente. O grupo controle foi manipulado com o aparelho desligado. Cada grupo foi avaliado em 3 diferentes espaços de tempo: 3o, 7o e 15o dia de pós-operatório. Foram feitas avaliações biométricas, morfométricas e estereológicas. Para a estatística foi utilizado o software PRISM 6.0 com o teste TWO-WAY ANOVA com pós-teste de BONFERRONI considerando p0,05 quando comparado o grupo controle versus grupo experimental. Quanto à espessura do epitélio e queratina, não houve diferença significante entre o grupo controle e os grupos tratados, entretanto grupos irradiados com maiores frequências apresentaram piores resultados no processo de cicatrização. Neste modelo experimental, o protocolo de utilização do ultrassom terapêutico interfere negativamente no processo de cicatrização de feridas quando utilizados em doses a partir de 1,5W/cm2.

Risk of Implant Loss in Patients with a History of Periodontitis: Umbrella Review
AimIndicate the rate of implant loss in patients with a history of evaluated periodontitisBackgroundPeriodontitis and peri-implantitis present similar microbiota, which presence and characteristics may be associated with external factors, such as dental hygiene, salivary dysfunctions, genetical properties or systemic diseases, and the role of these systemic factors in predisposing implant loss may not be despised.Methods and resultsLiterature searches up to February 2021 were conducted in six databases. Information regarding implant survival and loss, marginal bone loss and clinical index were gathered among the included studies. Risk of bias among the included studies was assessed with the ROBIS tool, performed among all the included studies by two reviewers. Level of agreement between researchers was calculated using the Kappa index.Eight systematic reviews with meta-analysis were included, and mean results indicated 30,95% (-69,26% to 131,16%, 95% CI) higher implant loss rates among patients with history of periodontitis. All the included studies presented high overall risk of bias.ConclusionPatients with history of periodontitis present higher risk of developing peri-implantitis, although better methodologically conducted studies may be performed.

Is there evidence that periodontal diseases are risk factors for coronary arterial disease?-Scoping review
Aim: To determine the scientific evidence regarding the condition of periodontal diseases (PDs) as risk factors of coronary artery diseases. Materials and methods: A scoping review was performed through the selection of articles from online databases (Medline via PubMed, LILACS, and Cochrane CENTRAL), using a search algorithm and eligibility criteria for data extraction and data synthesis of included papers. Four hundred forty-one studies from online databases and 1364 from reference lists were initially identified, and 34 articles were selected for inclusion. Articles had to be published between 2015 and 2020 and had to associate PDs to coronary arterial diseases. All studies comprised a sample of 446443 participants. Favorable opinions totaled 70.59%, and the cross-sectional observational study design was more frequently found (32.35%). Biochemical outcomes were showed more frequently, such as inflammatory biomarkers (58.82%). Despite a large advantage for favorable opinions, a statistically significant result was not found when extracted data were combined with studies opinions. Conclusion: The evidence was classified as level II-3, hence, still distant from the best ranks and can therefore be considered as unclear. Moreover, studies with the higher potential to generate evidence showed a high risk of bias.
