Resumo: Purpose: The aim of this study was to assess the contamination status of endodontic absorbent paper points from sterilized or not sterilized commercial packs, as well as paper points exposed to the dental office environment. Methods: Twenty absorbent paper points were evaluated for contamination status packed under different conditions: commercial/sterilized pack, commercial/non-sterilized pack, exposed to the clinical environment, and intentionally contaminated (positive control). Contamination was determined qualitatively and quantitatively by aerobiosis, capnophilic growth, and pour plate. The Petri dishes were analyzed with a colony counter, and the results were expressed as colony-forming units. The data were analyzed by Kruskal-Wallis test (α=0.05). Results: No difference in colony-forming units was found among the groups of endodontic absorbent paper points. All groups were contaminated by fungi and bacteria. Conclusion: It can be concluded that the sterilization of absorbent endodontic paper points before clinical use should be recommended regardless of commercial presentation.

Metodologia: Vinte cones de papel sob diferentes condições foram testados para verificar a contaminação: comercialmente esterilizados, comercialmente não esterilizados, expostos ao ambiente clínico, e intencionalmente contaminados. A contaminação foi determinada qualitativamente e quantativamente por diferentes condições: aerobiose, crescimento capnofílico ou pour plate. As placas Petri cultivadas com o cone foram analizadas através de contagem de colônias, e os resultados expressos em unidade formadora de colônias. Os dados foram analisados por teste de Kruskal-Wallis (α=0,05). Resultados: Não houve diferença estatística significante entre os grupos, sendo que todos cones de papel endodôntico estavam contaminados por bactérias e fungos. Conclusão: Concluiu-se que a esterilização de cones de papel endodônticos deve ser recomendada antes do uso clínico independente de sua apresentação comercial.EDIPUCRS - Editora Universitária da PUCRS2011-01-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Articlein vitro; laboratorialapplication/pdfhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/article/view/7485Revista Odonto Ciência; Vol. 26 No. 1 (2011); 56 - 60Revista Odonto Ciência; v. 26 n. 1 (2011); 56 - 601980-65230102-9460reponame: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/7485/6218Pereira, Érica RodriguesNabeshima, Cleber KeitiMachado, Manoel Eduardo de Limainfo:eu-repo/semantics/openAccess2013-11-11T12:11:58Zoai:ojs.revistaseletronicas.pucrs.br:article/7485Revistahttps://revistaseletronicas.pucrs.br/ojs/index.php/foPRIhttps://revistaseletronicas.pucrs.br/ojs/index.php/fo/oai||odontociencia@pucrs.br1980-65230102-9460opendoar:2013-11-11T12:11:58Revista odonto ciência (Online) - Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS)false
