Biocompatibilidade em pulpotomia de dentes decíduos: melhor material e alternativas ao uso do MTA: revisão sistemática e meta-análise / Biocompatibility in pulpotomy in deciduous teeth: best material and alternatives to MTA use: a systematic review and meta-analysis

Introdução: A terapia pulpar vital é o tratamento que visa a manutenção da vitalidade pulpar e da função do dente. Para a pulpotomia, os materiais são escolhidos baseados em algumas características fundamentais, tais como a biocompatibilidade e bioatividade. Atualmente, o Agregado de Trióxido Mineral (MTA) é o mais comumente utilizado para este procedimento. Objetivo: Identificar o melhor material para uso em pulpotomia em dentes decíduos considerando a propriedade de biocompatibilidade, através de revisão sistemática da literatura e metanálise. Material e Métodos: A pergunta norteadora foi: "Qual é o melhor agente para pulpotomia em termos de biocompatibilidade?". Foi realizada pesquisa nas bases de dados eletrônicas Medline/PubMed, SciELO, LILACS e Web of Science sem restrição de data inicial até outubro de 2020, usando os seguintes descritores padronizados pelo Medical Subject Headings (MeSH): "pulpotomy", "pulp therapy", "biomaterials", "biocompatible materials", "pulp capping agent", "pulp capping materials".Resultados: Um total de 358 estudos foram identificados, sendo 15 deles selecionados para análise qualitativa e seis para metanálise. A revisão avaliou aspectos clínicos, radiográficos e histológicos, considerando diferentes períodos de acompanhamento, amostras e metodologias. Diversos materiais foram encontrados e o MTA foi o mais frequente. Embora os resultados qualitativos tenham sido pouco conclusivos em relação ao melhor deles, foi possível estabelecer que o Cimento Portland é uma alternativa viável para a substituição do MTA. Conclusão: A metanálise demonstrou que o MTA é o material mais favorável para uso em pulpotomias em dentes decíduos.

Introduction: Vital pulp therapy is the treatment aimed at maintaining pulp vitality and tooth function. For pulpotomy, materials are chosen based on some fundamental characteristics, such as biocompatibility and bioactivity. Currently, Mineral Trioxide Aggregate (MTA) is the most commonly used for this procedure. Objective: To identify the best material for use in pulpotomy in deciduous teeth considering the property of biocompatibility, through a systematic review of the literature and meta-analysis. Materials and Methods: The guiding question was: "What is the best agent for pulpotomy considering the biocompatibility property?". A search was performed in the electronic databases MEDLINE/PubMed, SciELO, LILACS and Web of Science without an initial date until October 2020, using the following descriptors recognized by Medical Subject Headings (MeSH): "pulpotomy", "pulp therapy", "biomaterials", "biocompatible materials'', "pulp capping agent", "pulp capping materials". Results: A total of 358 studies were identified, 15 of them selected to qualitative analysis and six to meta-analysis. The revision evaluated clinical, radiographic and histological aspects, considering different follow-up periods, samples and methodologies. Several materials were found and MTA was the most frequent. Although the qualitative results were inconclusive in relation to the best of them, it was possible to establish that the Portland Cement is a viable alternative for MTA replacement. Conclusion: The meta-analysis demonstrated that MTA is the most favorable material for use in pulpotomies in deciduous teeth.

Avulsão de dentes permanentes e seu manejo: conhecimento de estudantesde Odontologia, Medicina e Enfermagem / Avulsion of permanent teeth and their management: knowledge of students of Dentistry, Medicine and Nursing students

O objetivo do presente estudo foi avaliar o conhecimento de estudantesdos cursos da área da saúde (Odontologia, Medicina e Enfermagem) de uma instituição pública de ensino superior sobre avulsão de dentes permanentes, bem como sobre as condutas de urgência a serem tomadas frente à lesão. Foram coletadas informações, por meio de um questionário estruturado autoaplicável, sobre dados pessoais, experiências anteriores, conhecimento sobre avulsão dentária e sobre as principais condutas a serem tomadas frente a este tipo de traumatismo. Foi realizada análise descritiva e análise estatística, utilizando o teste de Qui-quadrado de Pearson. O nível de significância adotado foi de 5% (p<0,05). A amostra, selecionada por conveniência, foi composta por 390 acadêmicos daUniversidade Federal de Juiz de Fora, sendo 154 do curso de Odontologia, 93 de Enfermagem e 143 de Medicina. Menos da metade dos entrevistados relataram ter recebidoanteriormentealguma informação sobre traumatismos dentoalveolares, sendo que a maioria que recebeu informação era do curso de Odontologia (p<0,01). A maioria também não teve nenhuma experiência anterior com esse tipo de traumatismo, sem diferença entre os cursos (p≥0,05). O estudo revelou que há falta de conhecimento sobre o manejo da avulsão de dentes permanentes pelos estudantesavaliados, principalmente os dos cursos de Medicina e Enfermagem. Desta forma, existegrande necessidade dodesenvolvimento de programas de educação, informação e treinamento, que enfatizem o tratamento emergencial para avulsão dentária, dirigidos aos alunos desses cursos (AU).

The aimof the present study was to evaluate the knowledge of undergraduate students ofhealth care courses (dentistry, medicine and nursing) from a public higher education institution about theavulsion of permanent teeth, as well as on emergency procedures to be taken in the occurrenceof this type of injury. Information was collected through self-administered structured questionnairecontainingpersonal data, previous experiences, knowledge about dental avulsion and about the main proceduresto be taken in the occurrenceof this type of trauma. Descriptive and statistical analysis was performed using Pearson's chi-square test. The significance level adopted was 5% (p <0.05). The sample, selected for convenience, was composed of 390 students from the Federal University of Juiz de Fora, 154 of them dentistrystudents,93 nursing studentsand 143 medicinestudents. Less than half of interviewees reported having previously received anyinformation about dentoalveolar trauma, and the majority who received some information were dentistrystudents (p <0.01). The majority also had no previous experience with this type of trauma, with no difference between courses (p≥0.05). The study revealed that there is lack of knowledge about the management of avulsion of permanent teeth by evaluatedstudents, especially those enrolled in medicine and nursing courses. Thus, there is great need for the development of education, information and training programs emphasizingthe emergency treatment for dental avulsion aimed at students of these courses (AU).

Biosafety in Dental Practices Versus COVID-19 Outbreak

ABSTRACT Objective: To evaluate the dentists' knowledge about biosafety considering the SARS-CoV-2 and the risks of increasing the COVID-19 outbreak by dental practices during the pandemic in Brazil. Material and Methods: A cross-sectional study was performed by internet-based snowball sampling technique. A questionnaire with questions about different content was applied, and then analyzed the following two parameters: participants' Brazilian region and professional's specialty. Results: A total of 413 e-questionnaires from all Brazilian regions were considered valid. There were no significant differences among biosafety measures adopted by participants from different Brazilian regions (p≥0.05), except for those from North region, which have applied less previous oral antisepsis, temperature screening, and specific anamnesis tracking COVID-19 symptoms (p<0.05). The unique use of N95 mask was positively associated with North region (p<0.05). Expert participants of Groups 2 (oral surgery and correlate areas) and 4 (orthodontics, oral radiology and facial jaw orthopedics) were more updated than other ones (p<0.05). Conclusion: The biosafety protocols applied by participants were not adequate for the epidemiologic status of COVID-19 in each region of Brazil, from 13th May to 17th June 2020. Specialties linked to microbiology area or structured social networks have better applied preventive measures for COVID-19.

The Novel Coronavirus: An Alert for Pacifiers' Disinfection

Objective: To evaluate the best strategy for pacifier disinfection methods. Material and Methods: The literature search was conducted on MEDLINE/PubMed, Scielo, Lilacs, Web of Science, and Scopus databases to find all relevant articles published over the past 20 years, based on PRISMA guidelines. Two reviewers extracted data independently by using a standardized form. The following factors were recorded: country of study, type of study, pacifier material, sample number, microorganisms analyzed, decontamination methods used, method accessibility and results found. Results: A total of 121 articles were obtained from all databases. The selected documents underwent a final screening, resulting in 8 articles. The method of disinfection analyzed by the literature were: 3.5% neutral detergent, apple cider vinegar 70% spray, boiling water during 15 minutes, sodium hypochlorite 2.5, hydrogen peroxide 70% spray, chlorhexidine 0.12%, Brushtox®, sterile water and microwave. Conclusion: Because of the broad methods for pacifier disinfection and different levels of accessibility to disinfectant agents, the pacifier consensus for decontamination remains unclear. Although the disinfection methods are diverse, the methods suggested to its disinfection were identified and described in this article.
