Comparative clinical evaluation of conventional syringe irrigation, endoactivator and endovac in reducing the microbial count from infected root canal
An in vivo study

endoactivator, endovac, disinfectionAbstract
Root canal decontamination is a crucial step in achieving endodontic success. For this, absolute eradication of microbes from root canal is of paramount importance. This in vivo study aimed at comparing the Conventional, EndoActivator and EndoVac irrigation system in reducing intracanal bacterial load. 70 necrotic, single rooted teeth having chronic periapical lesions were selected for endodontic therapy and randomly assigned into three groups. Group 1 – 20 teeth treated using Conventional needle irrigation. Group 2 – 20 teeth treated using EndoActivator system. Group 3– 20 teeth treated using EndoVac system. After the surface disinfection, access opening was done. Groupwise irrigation with NaOCl (VISHAL DENTOCARE PVT.LTD.) and EDTA (AMMDENT CANALARGE) was done with each canal in between instrumentation. Data were obtained by culturing bacterial samples of root canal before and after chemomechanical preparation under both aerobic and anaerobic conditions and CFU was counted. Statistical analysis - Paired‘t’ test was used for intragroup comparisons while ANOVA test followed by the “post hoc Games Howell test” for intergroup comparisons. Significant post-operative reduction in bacterial colony counts was seen with all the groups. EndoVac group had significantly higher mean log reduction in CFU counts than Conventional group.
