Antimicrobial Efficacy of a Novel Automated Irrigation Device As Compared to Conventional Needle Irrigation Against Enterococcus faecalis: An In Vitro Study

Aim The present study aims to compare the antibacterial efficacy of a novel automated endodontic irrigation device with that manual technique. Materials and methods considered 45 extracted single-rooted teeth. After sectioning teeth, specimens were inoculated Enterococcus faecalis (E. faecalis) bacteria for three weeks. Instrumentation was done using ProTaper Gold rotary files size 50 5% taper. Based on protocol, experimental samples divided into Group I: control (normal saline irrigation) (n = 15); II: conventional needle III: 15). in III device. irrigation, pre-weighted dentinal shaving collected Eppendorf tubes, diluted 10 times, incubated Petri dish tryptone soy agar (TSA) 48 hours. Finally, colony-forming unit (CFU) counts assessed. IBM SPSS Statistics Windows version 23.0 (Armonk, NY, USA, Corp.) used data analysis. Intergroup comparisons made non-parametric Kruskal-Wallis test. Results mean CFU count (CFU/ml) groups was: 1 irrigation): 3.67x101; 2 (manual 2.69× 101; 3 (automated 1.57× 101. A statistically significant reduction E. seen among assessed (p<0.01). group exhibited most substantial count. showed difference compared (p<0.05). Conclusions superior reducing counts. This indicates has potential enhance bacterial elimination during treatment.
