Facial skin injuries caused by individual protectors in the combat to covid-19 / Lesões cutâneas faciais causadas por protetores individuais no combate à covid-19

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.

RESUMO O Coronavírus possui ácido ribonucléico de fita simples, sendo o sétimo membro conhecido da família Coronaviridae que infectam humanos. As gotículas e aerossóis que ficam suspensas no ar com o vírus pode ser transmitido por contato como mucosas bucal, nasais e oculares, podendo causar a síndrome respiratória aguda grave. Devido ao surto da nova doença do coronavírus, tornou-se necessário a utilização constante dos equipamentos de proteção individual pelos profissionais de saúde, visto que o vírus possui disseminação rápida e generalizada. Mas, inesperadamente o surto do coronavírus trouxe outra preocupação, o surgimento de lesões faciais pelo uso contínuo e inadequado destes protetores individuais, prejudicando a saúde desses profissionais. Uma alternativa para amenizar e prevenir tais lesões seria a utilização de cremes e curativos profiláticos nos locais onde há pressão causada por estes equipamentos, assim como o alivio das cargas geradas pelos mesmos, em intervalos que não ultrapassem 4 horas. Diante disso, esta revisão de literatura objetivou relatar o potencial de surgimento de lesões faciais causado pelo uso continuo e inadequado dos EPI's, evidenciando as áreas mais acometidas, os riscos à saúde do profissional, a prevenção e o tratamento, através da consulta eletrônica à base de dados, PUBMED, SCOPUS e Bireme/BVS.

3D printing applications during COVID-19 pandemic: a literature review / As aplicações da impressão 3D durante a pandemia de COVID-19: uma revisão da literatura

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.

RESUMO A rápida disseminação da COVID-19 ao redor do mundo gerou significativos impactos no modo de viver das sociedades, sendo um deles, a escassez de equipamentos de proteção individual (EPIs) para trabalhadores que atuam na linha de frente no combate ao vírus. A insegurança sanitária levou populações e profissionais da saúde a uma busca desenfreada por equipamentos de proteção, além de outros aparatos necessários à manutenção da vida, tanto dos pacientes, quanto dos profissionais, revelando as limitações dos sistemas de saúde diante de crises em grande escala, como a pandemia da COVID-19. Buscou-se, por meio do presente trabalho, apresentar as iniciativas de profissionais e empresas relacionadas à impressão 3D de compartilharem programas e recursos com o intuito de abastecer trabalhadores na linha de frente, que têm sido importantes aliados no combate aos efeitos provocados pelo novo coronavírus. Para isso, foi realizada uma pesquisa em quatro bases de dados eletrônicas, sendo elas: SCOPUS, BVS, EMBASE e MEDLINE via PUBMED. Após análise dos critérios de inclusão e exclusão, foi confeccionada uma tabela de resultados com as principais características dos produtos fabricados e disponibilizados, assim como a instituição envolvida. Concluiu-se, portanto, que as aplicações da impressão 3D nessas iniciativas tiveram grandes contribuições para a saúde pública e a indústria aditiva durante o período da pandemia da COVID-19.

Quality of models supplied to dental laboratories for the fabrication of partial removable denture framework / Qualidade de modelos enviados aos laboratórios para execução de prótese parcialmente removível

ABSTRACT Objective The aim of this study was to evaluate the models and plannings of metallic framework of removable partial prosthesis sent to dental laboratories in the city of Recife. Methods: The physical and technical conditions of plaster models were sent by the dentists to 4 dental laboratories. All models were examined, photographed and recorded on a form according to the research objective. Results: A total number of 235 models sent by dental surgeons were used to prepare the metallic structure, in which none of the models presented surveying nor the path of insertion. Out of the 235 models, 41 (17.44%) presented serious failures, such as positive and negative bubbles, broken dental elements, direct retainers and damaged edentulous areas. With respect to the planning, only 22 (9.35%) models were presented with the metallic framework planning, but in an unsatisfactory way. Regarding mouth preparation, no model presented a guide plane, and only 6.8% of models had rests seats, but incorrectly prepared. Conclusion: The models evaluated presented poor quality, lack of planning and no mouth preparation. This shows the need for dental surgeons to be aware of the appropriate prosthesis models and plannings in order to ensure a satisfactory and long-term rehabilitation of the patient, as well as preserving the remaining mouth structures.

RESUMO Objetivo Avaliar os modelos e planejamentos das estruturas metálicas das próteses parciais removíveis enviadas aos laboratórios de prótese dentária da cidade do Recife. Métodos Foram avaliadas as condições físicas e técnicas dos modelos de gesso enviados pelos dentistas à 4 laboratórios de prótese dentária. Todos os modelos foram examinados, fotografados e registrados por meio de um formulário de acordo com o objetivo da pesquisa. Avaliou-se 235 modelos enviados pelos cirurgiões dentistas para confecção da estrutura metálica, na qual nenhum dos modelos apresentou delineamento e registro do eixo de inserção. Resultados Dos 235 modelos, 41 (17,44%) apresentaram falhas graves, tais como bolhas positivas, bolhas negativas, elementos dentários quebrados, retentores diretos e áreas edêntulas danificados. Quanto ao planejamento, apenas 22 (9,35%) modelos apresentavam-se com o desenho da estrutura metálica, porém, de maneira insatisfatória. Quanto ao preparo de boca, nenhum modelo apresentou preparo de plano guia, e apenas 6,8% dos modelos possuíam nichos, porém confeccionados de maneira incorreta. Conclusão Os modelos avaliados apresentaram qualidade insatisfatória, ausência de planejamento e realização de preparo de boca. Isto demonstra a necessidade de conscientização dos cirurgiões dentistas para a confecção dos modelos e planejamentos adequados das próteses, a fim de garantir uma reabilitação duradoura e satisfatória ao paciente, assim como proservação das estruturas bucais remanescentes.

Evaluation of oral health-related quality of life in individuals with type 2 diabetes mellitus

Aim: The aim of the present study was to evaluate the impact of oral problems on the quality of life of individuals with type 2 diabetes mellitus (DM2). Methods: A population-based, cross-sectional study was conducted with a random sample of 302 individuals with DM2 who answered the Oral Health Impact Profile 14 (OHIP-14) questionnaire as well as a questionnaire addressing socioeconomic and oral health characteristics. After filling out the questionnaires, the participants were submitted to a clinical dental examination Periodontal diseases, dental caries and edentulism. Data analysis involved descriptive statistics, bivariate analysis and logistic regression. Results: The prevalence of impact on oral health-related quality of life (OHRQoL) was 47%. In the multivariate analysis, the variables that remained significantly associated with a negative impact on quality of life were xerostomia (OR= 2.15; 95% CI: 1.07-4.30), denture need (OR= 3.71; 95% CI: 1.17-11.73) and periodontitis (OR= 5.02; 95% CI: 2.19-11.52). Conclusion: The prevalence rate of impact on OHRQoL was high in the sample studied. Xerostomia, denture need and periodontitis posed a risk of negative impact on the quality of life of individuals with DM2, independently of socioeconomic status

The impact of dental anxiety and dental fear on the periodontal status and quality of life among dental patients

Aim: The aim of the study was to investigate levels of Dental Fear (DF) and Dental Anxiety (DA) among individuals awaiting appointments at the clinics of two courses in dentistry and determine the impact on oral health status and quality of life. Methods: An observational study was conducted with a sample of adult dental patients. Levels of DF and DA and the perception of quality of life were determined using questionnaires and periodontal data. Results: Among the 287 subjects, 71.4% were female, 7.3% were classified as very anxious and 16% were classified as anxious. Gender was significantly associated with DA (p = 0.001); 20% of the female volunteers and 6.1% of the males were classified as anxious. The frequency of moderate and extreme fear was 42.9% and was not significantly correlated with gender (p = 0.071). The prevalence of a negative impact from oral health status on quality of life (measured using the OHIP-14 scale) was 38.3% and income was significantly associated with this outcome (p = 0.000). Conclusion: Levels of DA and DF were substantial among the individuals analyzed. Women with a lower education were susceptible to anxiety. DA and DF were associated with periodontal status or impact on quality of life
