Abstract

Introduction: Blood is a biological material with high potential of infectious transmission in dental environments, including herpes simplex, hepatitis and AIDS. Aim: To investigate the efficacy of luminol in detecting blood in endodontic files before and after the sterilization process. Material and method: Luminol was used to investigate the presence or absence of traces of blood tissue in 50 endodontic files, visible to naked eye or not, after performing endodontic treatment and after the cleaning/sterilization process. The results obtained were tabulated and statistically analyzed by using the Friedman’s test at a significance level of 5% (p<0.05). Result: By naked eye, it was found that 31/50 files showed no trace of blood, 8/50 showed a slight presence of blood and 11/50 showed a considerable presence of blood after endodontic treatment. After the use of luminol, however, 16/50 endodontic files showed no trace of blood, 19/50 showed a slight presence of blood and 15/50 showed a considerable presence of blood. After the cleaning and sterilization process, no blood was detected in the files. Conclusion: It was concluded that the luminol solution is effective in detecting blood tissue in endodontic files as well as in validating the cleaning/sterilization process.

Resumo

Introdução: Sangue é um material biológico com alto potencial de transmissão de infecção em ambientes odontológicos, incluindo herpes simples, hepatites e AIDS. Objetivo: Investigar a eficácia do luminol em detector sangue em limas endodônticas antes e após o processo de esterilização. Material e método: Luminol foi utilizado para investigar a presença ou ausência de vestígios tecido sanguíneo em 50 limas endodônticas, visíveis ou não à olho nu, após a realização do tratamento endodôntico e após o processo de limpeza/esterilização. Os resultados obtidos foram tabulados e analisados estatisticamente utilizando o teste de Friedman com nível de significância de 5% (p<0,05). Resultado: A olho nú, foi observado que 31/50 limas não apresentaram vestígios de sangue, 8/50 apresentaram uma leve presença de sangue e 11/50 apresentaram uma presença considerável de sangue após o tratamento endodôntico. Após a utilização do luminol, entretanto, 16/50 limas endodônticas não apresentaram vestígios de sangue, 19/50 apresentaram uma leve presença de sangue e 15/50 apresentaram uma presença considerável de sangue. Após o processo de limpeza e esterilização não foi detectado sangue nas limas endodônticas. Conclusão: A solução de luminol é efetiva na detecção de tecido sanguíneo em limas endodônticas, validando o processo de limpeza/esterilização.
