Resumo: | Objectives: To produce a systematic review regarding the effect of graphene-reinforced polymethylmethacrylate used in dentistry on mechanical properties. Methods: Electronic databases (Pubmed/MEDLINE, Web of Science, Embase) were independently searched by two researchers for relevant studies published up to December 2021. An additional manual search was performed to identify relevant publications. The population, intervention, comparison, and outcome (PICO) question was “In dentistry, does graphene-reinforced polymethylmethacrylate offer better mechanical properties than conventional polymethylmethacrylate?”. The selection of articles was carried out according to the established inclusion and exclusion criteria, following the PRISMA flowchart. The inter-investigator reliability was assessed by Cohen's Kappa coefficient. The risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Quasi-experimental Studies. Results: Six in vitro studies were included in the qualitative analysis. A total of 247 specimens were evaluated: 81 made of non-reinforced PMMA resin and 166 of PMMA reinforced with graphene. The mechanical properties evaluated were flexural strength, flexural modulus, hardness, biaxial flexural strength, and impact strength. These properties seem to improve with the addition of graphene in certain concentrations. The analysis of the risk of bias showed low risk. Conclusions: Within the limitation of this study, graphene seems to strengthen some mechanical properties of PMMA dental resin. However, more studies are needed to understand the ideal graphene concentration to improve resin's clinical performance. |

Métodos: Dois investigadores independentes efetuaram uma pesquisa em três bases de dados (Pubmed/MEDLINE, Web of Science, Embase) até 31 de dezembro de 2021. Realizou-se também uma pesquisa manual para identificar publicações relevantes. A pergunta de in vestigação definida foi “Em medicina dentária, o polimetilmetacrilato reforçado com grafe no apresenta melhores propriedades mecânicas do que o polimetilmetacrilato convencio nal?”. A seleção dos artigos seguiu o fluxograma PRISMA, considerando os critérios de inclusão e exclusão definidos. A concordância entre investigadores foi calculada pelo coe ficiente Kappa de Cohen. A qualidade dos estudos foi avaliada através da checklist do Joanna Briggs Institute para estudos quasi-experimentais. Resultados: Seis estudos in vitro foram incluídos na análise qualitativa. No total dos estudos analisados nesta revisão foram avaliados 247 provetes, 81 dos quais eram compostos por polimetilmetacrilato convencional e 166 por polimetilmetacrilato aditivado com grafeno. As propriedades mecânicas avaliadas foram: resistência à flexão, módulo de elasticidade, du reza, resistência à flexão biaxial e resistência ao impacto. Maioritariamente, estas proprie dades melhoraram com a adição de determinadas concentrações de grafeno. A análise da qualidade dos artigos demonstrou um baixo risco de viés. Conclusões: Considerando as limitações deste estudo, podemos concluir que o grafeno pa rece melhorar algumas propriedades mecânicas do polimetilmetacrilato utilizado em me dicina dentária. No entanto, mais estudos são necessários para se compreender a concen tração ideal de grafeno para se obter o melhor desempenho clínico das resinas protéticasVeritati - Repositório Institucional da Universidade Católica PortuguesaSalgado, HelenaFonseca, PatríciaVaz, MárioFigueiral, Maria HelenaMesquita, Pedro2023-02-01T10:16:15Z2022-12-282022-12-28T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.14/40065eng1646-289010.24873/J.RPEMD.2022.12.104685146272792000933739000001info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-07-12T17:45:36Zoai:repositorio.ucp.pt:10400.14/40065Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T18:32:49.247367Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
