Enquadramento: Os materiais restauradores desempenham um papel importante na infecção cruzada, devendo apresentar resistência às forças mastigatórias, evitando, igualmente, fenómenos de micro-infiltração, protegendo, assim, a polpa, no caso de o dente estar vital ou a obturação do sistema de canais radiculares, no caso do dente ter um tratamento endodôntico. Objetivo: Revisão sistemática da evidência científica publicada sobre a utilização de quitosano em Medicina Dentária Conservadora. Material e métodos: Revisão sistemática da literatura realizada através da metodologia Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Nas bases de dados científicas: PubMed e Scopus, com os operadores booleanos AND e OR, tendo resultado na expressão de busca composta exclusivamente por termos MeSH: (<chitosan=) AND ("dentistry") OR (<oral health=) OR (<dental materials=). A selecção dos estudos com a aplicação dos critérios de inclusão e de exclusão, foi feita por dois investigadores independentes. Resultados: Foram incluídos seis estudos que constituíram o corpus de análise final. Ficou, assim, demonstrado que, em adesivos dentinários, compósitos e cimento de ionómero de vidro, a adição de quitosano, na forma de nanopartículas, em comparação sem adição de quitosano, resultou numa melhor força de adesão, em propriedades antimicrobianas e melhores propriedades mecânicas. Conclusão: Os resultados podem ser úteis para investigações futuras sobre a incorporação de quitosano em materiais restauradores, área ainda não extensivamente explorada. Esta revisão sistemática da literatura fornece, também, informações para ajudar a explorar melhor o pré-tratamento da dentina afectada por cárie com quitosano antes da restauração com resina composta.
Context: Restorative materials play a crucial role in preventing cross-infection, requiring the ability to withstand masticatory forces. Additionally, they must prevent micro-leakage to protect the pulp in vital teeth or the filled root canal system in endodontically treated teeth. Objective: This study aims to systematically review the published scientific evidence regarding the application of chitosan in Conservative Dentistry. Materials and Methods: A systematic literature review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were performed in the scientific databases PubMed and Scopus using the Boolean operators AND and OR, resulting in a search query composed exclusively of MeSH terms: (<chitosan=) AND (<dentistry=) OR (<oral health=) OR (<dental materials=). The selection of studies was carried out by two independent researchers based on predefined inclusion and exclusion criteria. Results: Six studies met the inclusion criteria and constituted the final corpus for analysis. The findings demonstrate that the incorporation of chitosan in the form of nanoparticles into dentine adhesives, composites, and glass ionomer cement, compared to formulations without chitosan, resulted in enhanced adhesion strength, superior antimicrobial properties, and improved mechanical characteristics. Conclusions: These findings may inform future research regarding the integration of chitosan into restorative materials, an area that has not been extensively explored. This systematic review also provides insights that may facilitate further investigations into the pre-treatment of carious dentin with chitosan prior to restoration.
