Resumo: Objective: The influence of low level laser (l 670 nm) was evaluated regarding the foreign body reaction and inflammatory response around silk and polyglactin 910 rapid absorbing sutures.Methods: Forty rats were divided into control and irradiated groups and in four subgroups represented by the type of suture material and by the study period - 7 and 14 days. After transfixation of the suture material, the irradiated group was submitted to laser therapy (GaAlAs, 670 nm, 9 mW). Through tissue sections stained with HE, foreign body reaction and inflammatory cell infiltration were analyzed around the wires.Results: Around the silk, foreign body reaction and inflammation were reduced in the groups treated with laser in both periods. Compared to polyglactin 910, laser intensified the presence of multinucleated giant cells. The differences in both sutures and in different groups were not statistically significant.Conclusion: Laser in absorbable sutures increases the foreign body reaction and inflammation in relation to non-absorbable sutures.

Após a transfixação do fio de sutura, o grupo irradiado foi submetido à laserterapia (GaAlAs, l670nm, 9mW). Através de secções teciduais analisou-se a reação de corpo estranho e infiltrado inflamatório em volta dos fios. Resultados: Ao redor do fio de seda houve redução da reação de corpo estranho e da inflamação nos grupos tratados com laser. No décimo quarto dia a redução da inflamação foi estatísticamente significativa (p=0,008). Na presença da poliglactina 910 de rápida absorção, o laser estimulou o aumento de macrófagos e de células gigantes multinucleadas e a manutenção de filamentos do fio apesar das diferenças não serem estatíticamente significantes em relação ao grupo controle.Conclusão: No fio de sutura absorvível o laser intensificou a reação de corpo= estranho e a resposta inflamatória em relação aos fios não absorvíveis.EDIPUCRS - Editora Universitária da PUCRS2016-03-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/1394210.15448/1980-6523.2015.4.13942Revista Odonto Ciência; Vol. 30 No. 4 (2015); 105-110Revista Odonto Ciência; v. 30 n. 4 (2015); 105-1101980-65230102-946010.15448/1980-6523.2015.4reponame:Revista odonto ciência (Online)instname:Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)instacron:PUC_RSenghttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/13942/14425Copyright (c) 2016 Revista Odonto Ciênciainfo:eu-repo/semantics/openAccessAmaral, Ingrid Esteves de VillemorSilva, Ana Carolina Ribeiro N.Hoshi, RyuichiMedrado, Alena PeixotoAndrade, Miguel Gustavo SetubalReis, Silvia Regina de Almeida2016-06-16T13:49:48Zoai:ojs.revistaseletronicas.pucrs.br:article/13942Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2016-06-16T13:49:48Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
