Evaluation of antimicrobial efficacy of Aloe vera and its effectiveness in decontaminating gutta percha cones

AIM: The aim of this study was to evaluate the antimicrobial efficacy of Aloe vera and to determine its effectiveness in decontaminating gutta percha cones. MATERIALS AND METHODS: A concentrated extract of Aloe vera was used to check for the antimicrobial efficacy using the agar well diffusion method. Presence of zones’ of diffusion was identified against three common GP contaminants namely, E.coli, E.faecalis and Staph. aureus. New GP Cones, freshly taken out of the packet were then decontaminated for 1minute using Aloe vera gel and then placed in thioglycolate broth to check for the presence of turbidity. RESULTS: The zones of inhibition on the agar plate were measured as 24mm,21mm and 24mm respectively. The broth remained clear even after 48 hours of incubation. CONCLUSION: We conclude that Aloe vera is indeed effective as a GP decontaminant and it holds a promising future as a medium for storage of GP cones.
