Resumo: Purpose: To evaluate the effect of the use of 0.5% and 2% chlorhexidine digluconate on the immediate bond strength of a conventional adhesive system to dentin in primary teeth. Methods: Twenty-one healthy primary molars were divided into three groups (n=7), being one control (A) and two experimental groups (B and C). After dentin exposure, in Group (A) the adhesive procedure was performed using 37% phosphoric acid gel (15 s); dentin was washed (15 s), air dried (30 s) and rehydrated with water. Groups B and C followed similar procedures but for re-hydration with 0.5% and 2% chlorhexidine, respectively, for 30 s. A resin composite block was built simulating a restoration, and the teeth were stored in distilled water at 37°C for 24 h before the microtensile bond strength test. The bond strength data were analyzed by analysis of variance. Results: No statistically significant difference in bond strength was found among the tested groups (P>0.05) Conclusion: The 0.5% and 2% concentrations of chlorhexidine presented similar behavior and caused no adverse effects on the bond strength to dentin in primary teeth.

Metodologia: Vinte e um molares decíduos hígidos foram divididos em três grupos (n=7), sendo um controle e dois experimentais. Após a exposição da dentina, foi realizado no grupo controle (A) o procedimento adesivo utilizando ácido fosfórico gel a 37% (15 s); a superfície foi então lavada (15 s), seca com ar (30 s) e reidratada com água. Os grupos B e C foram idênticos ao grupo A, apenas com diferença no reumidecimento de clorexidina 0,5% e 2% respectivamente, por 30 s. Após a confecção do bloco de resina composta, os dentes foram armazenados em água destilada a 37°C por 24 h antes do teste de microtração. Os dados de resistência de união foram avaliados através de análise de variância. Resultados: Os dados apresentaram distribuição homogênea, não havendo diferença estatisticamente significante entre os grupos (P>0,05). Conclusão: As concentrações de clorexidina a 0,5% e 2% apresentaram comportamentos similares e não causaram efeitos adversos na resistência de união em dentina de dentes decíduos, quando comparadas ao grupo controle.EDIPUCRS - Editora Universitária da PUCRS2010-01-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articleapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/5880Revista Odonto Ciência; Vol. 25 No. 1 (2010); 88 - 91Revista Odonto Ciência; v. 25 n. 1 (2010); 88 - 911980-65230102-9460reponame: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/5880/4869Manfro, Aline Rosler GringsReis, AlessandraLoguercio, Alessandro DouradoImparato, José Carlos PettorossiRaggio, Daniela Prócidainfo:eu-repo/semantics/openAccess2013-11-11T12:48:37Zoai:ojs.revistaseletronicas.pucrs.br:article/5880Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:48:37Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
