Resumo: The objective this paper is evaluate influence of photoativation with halogen light and LED on conversion’s degree of two different composites. Thirty samples were divided in six groups considering type of composite, photoativation unit and type of polimerization used. Raman spectrophotometry was used to measure the degree of conversion. The Non-polimerized and polimerized samples were compared to evaluate if there was any difference on the degree of conversion to Ho1: composites; Ho2: diferent polimerization sources and Ho3: diferent activation modes. Anova and T Student were utlilized to statistical analysis. Results showed difference between the degrees of conversion of the different composites expressing a higher value for nanoparticulate resins, which could be explained by the presence of the TEGDMA on the composition of the matrix.

Trinta amostras foram divididas em seis grupos variando tipo de resina, tipo de lâmpada e tipo de ativação. Para medir grau de conversão foi utilizada espectrofotometria por Raman. As amostras não polimerizadas e polimerizadas foram comparadas para avaliar se houve diferença no grau de conversão para Ho1: os diferentes compósitos; Ho2: as diferentes fontes luminosas e Ho3: os diferentes modos de ativação. Para análise estatística foram utilizados Anova e T de Student. Os resultados mostraram haver diferença estatística, demonstrando maior grau de conversão para resinas nanoparticuladas, o que pode estar ligado à presença de TEGDMA em sua matriz.Associação Brasileira de Odontologia - Seção Rio de Janeiro2011-02-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Descritivaapplication/pdfhttps://revista.aborj.org.br/index.php/rbo/article/view/19710.18363/rbo.v67n2.p.220Revista Brasileira de Odontologia; v. 67, n. 2 (2010); 220Revista Brasileira de Odontologia; v. 67, n. 2 (2010); 2201984-3747reponame:Revista Brasileira de Odontologiainstname:Associação Brasileira de Odontologia (ABO)instacron:ABOporhttps://revista.aborj.org.br/index.php/rbo/article/view/197/193Direitos autorais 2016 Revistasinfo:eu-repo/semantics/openAccessRitto, Fernanda PittaBorges, Márcio Antônio ParaízoBastian, Fernando LuizMichelon, Marcela Mendes MedeirosMatos, Irma Cunha2011-02-09T13:26:47Zoai:revista_aborj_org_br.www.revista.aborj.org.br:article/197Revistahttps://revista.aborj.org.br/index.php/rboONGhttp://www.revista.aborj.org.br/index.php/rbo/oaihttps://revista.aborj.org.br/index.php/rbo/oai0034-72721984-3747opendoar:2011-02-09T13:26:47Revista Brasileira de Odontologia - Associação Brasileira de Odontologia (ABO)false
