Objetivo: Responder à seguinte questão de investigação: qual é o impacto das diferentes faixas de temperatura nas peças dentárias e em materiais restauradores tais como amálgama, resina composta, ionómero de vidro e coroas metalocerâmicas?
Metodologia: Foi efetuada uma pesquisa da literatura publicada entre 2004 e 2022 em bases de dados eletrónicas: PubMed, B-ON e ScienceDirect. A pesquisa foi sujeita a critérios de inclusão e exclusão devidamente identificados e os estudos foram selecionados seguindo os critérios do diagrama Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A avaliação da qualidade metodológica dos artigos foi realizada de acordo com a ferramenta de Quality Assessment Tool For In Vitro Studies (QUIN) para os estudos in vitro.
Resultados: Dos 46 639 artigos potencialmente elegíveis, foram incluídos 8 estudos in vitro após a aplicação dos critérios de inclusão e exclusão estipulados. Os estudos indicam que os materiais restauradores têm a capacidade de resistir a elevadas temperaturas e exibem padrões de alterações macroscópicas e microscópicas específicas a cada faixa de temperatura.
Conclusão: A evidência dos estudos in vitro sugere que as restaurações com amálgama, as com coroas cerâmicas/metalocerâmicas e os tratamentos endodônticos apresentam menos alterações, quer nas suas composições químicas, quer ao nível macroscópico ou microscópico em comparação com outros materiais restauradores comuns, como por exemplo o compósito. Estes fornecem uma fonte de evidência forense após exposição a temperaturas até 1000°C, que podem ser usadas como meio de comparação e identificação positiva de vítimas sujeitas a altas temperaturas.
Objective: To answer the following research question: what is the impact of different temperature ranges on teeth and restorative materials such as amalgam, composite resin, glass ionomer and metal-ceramic crowns? Methodology: A literature search of articles published between 2004 e 2022 in electronic databases was carried out: PubMed, B-ON and ScienceDirect. The research was subjected to inclusion and exclusion criterias properly identified and the studies were selected following the Preferred Reporting Items for Systematic Reviews and Meta-Analyse (PRISMA) criteria. Methodological quality of the articles was assessed according to the Quality Assessment Tool For In Vitro Studies (QUIN) for in vitro studies. Results: Of the 46 639 potentially eligible articles, 8 in vitro studies were included after applying the stipulated inclusion and exclusion criteria. Studies indicate that restorative materials have the ability to resist high temperatures and exhibit patterns of macroscopic and microscopic changes specific to each temperature range. Conclusion: Evidence from in vitro studies suggests that amalgam restorations, ceramic and metaloceramic crowns and endodontic treatments show fewer changes, either in their chemical compositions, or at the macroscopic and microscopic level, compared to other common restorative materials such as the composite. They provide a source of forensic evidence after exposure to temperatures up to 1000°C that can be used as means of comparison and positive identification of victims subjected to high temperatures.
