Para a realização do teste de infiltração, confeccionou-se um dispositivo para cada dente que permitiu a contaminação por Enterococcus faecalis e posterior preparo químico-mecânico. As amostras foram submetidas ao preparo biomecânico com diâmetro cirúrgico correspondente à lima #45 e mesma conicidade nos terços médio e cervical e receberam protocolo de desinfecção com hipoclorito de sódio a 2,5% (NaOCl), Clorexidina a 2% (CHX), óleo de girassol ozonizado a 2400ppm (OGO), PDT após irrigação com soro fisiológico (PDT+S) e PDT após irrigação com hipoclorito de sódio a 2,5% (PDT+H). As dez raízes restantes constituíram os controles positivo e negativo, sendo cinco dentes para cada grupo. Os controles positivos foram infectados e não foi utilizado nenhum agente irrigante. Os controles negativos foram compostos por dentes não contaminados pelo E. faecallis. Resultados: Os resultados da contagem de UFC/mL total e análise descritiva foram realizados. NaOCl e PDT+H apresentaram crescimento bacteriano inferiores aos valores de referência e foi considerado nulo. CHX e PDT+S apresentaram crescimento bacteriano baixo e OGO apresentou crescimento bacteriano moderado. Conclusão: NaOCl e PDT+H apresentaram melhor desempenho em relação aos demais protocolos de desinfecção utilizados. OGO apresentou crescimento bacteriano moderado sugerindo inviabilidade de sua utilização isolada em protocolos de desinfecção em endodontiaAim: The present “in vitro” pilot study evaluated the antimicrobial effects of sodium hypochlorite, chlorhexidine, photodynamic therapy, and ozonated sunflower oil, which were used as irrigating agents in the elimination of Enterococcus faecalis in the root canals of extracted human teeth. Methods: Sixty roots of single-root teeth (n = 60) were selected and autoclaved to perform the laminar flow experiment. To perform the infiltration test, a device was constructed for each tooth, which allowed for contamination by Enterococcus faecalis, and the tooth’s subsequent chemical-mechanical preparation. The samples were submitted to biomechanical preparation with surgical diameter, corresponding to file #45 and the same taper in the middle and cervical thirds, and received a disinfection protocol with 2.5% sodium hypochlorite (NaOCl), chlorhexidine 2% (CHX), ozonized sunflower oil at 2400ppm (OGO), PDT after irrigation with saline solution (PDT+S), and PDT after irrigation with 2.5% sodium hypochlorite (PDT + H). The remaining ten roots were positive and negative controls, with five teeth in each group. Positive controls were infected, and no irrigating agent was used. Negative controls consisted of teeth that were not contaminated by E. faecallis. Results: The results of the total CFU count and descriptive analysis were performed. NaOCl and PDT+H presented a bacterial growth of much lower t than the reference values and was considered null. CHX and PDT+S presented low bacterial growth, while OGO presented moderate bacterial growth. Conclusion: NaOCl and PDT + H presented better performance in relation to the other disinfection protocols used in this study. OGO presented moderate bacterial growth, suggesting its unviable use in endodontic disinfection protocolsporUniversidade Federal de Minas GeraisUFMGBrasilFAO - DEPARTAMENTO DE ODONTOLOGIA RESTAURADORAArquivos em odontologia (UFMG)DesinfecçãoEndodontiaFotoquimioterapiaHipoclorito de sódioClorexidinaEnterococcus faecalisPreparo de canal radicularExtração dentáriaEstudo piloto da análise comparativa da atividade antimicrobiana da PDT e agentes irrigantes em canais radiculares inoculados com Enterococcus faecalis “in vitro”A pilot study of the comparative analysis of the antimicrobial activity of PDT and irrigating agents in root canals inoculated with Enterococcus faecalis “in vitro”info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://periodicos.ufmg.br/index.php/arquivosemodontologia/issue/view/668Caroline Christine Santa Rosa CarolineChristiane Valente AraújoMonize Ferreira Figueiredo de CarvalhoPatricia Valente Araujoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
