Evaluation of Cymbopogon Citratus as Disinfectant and its Effect on the Dimensional Stability of the Resultant Gypsum Casts: An in Vitro Study.

BACKGROUND AND AIM: Proper disinfection of impression is probably the most important procedure for dental lab to render it safe further handling without affecting accuracy fine details. In light these intermingling facts, author aimed 1) investigate antimicrobial effect Cymbopogon citratus on selected microorganism colony and 2) disinfectant solution dimensional resultant gypsum casts. MATERIALS & METHOD: Initially, tropicalgin Alginate was mixed total 20 impressions alginate painted with bacterial colonies. Swabs were subjected culture sensitivity tests predetermined strains. immersed in glutaraldehyde 2% Citratus 30% 10 minutes (ten each). The swabs wiped glass Petri dish inoculated. colonial growth transferred slide Gram staining which confirmed presence Staphylococcus aureus, Streptococcus mutans Candida albicans control group. Cross-arch distance between 16 26 poured samples compared cross arch typhodont teeth using digimatic vernier caliper. RESULT: Statistical analysis attempted SPSS version 22.0. results Glutaraldehyde (Group A) mean reading 55.114, Variance =0.00687 standard deviation 0.8289 obtained. Cymbopogan B) 55.403, = 0.0268 0.16384 CONCLUSION: Within limitations study, authors concluded that anti-microbial efficacy less comparison this study superior glutaraldehyde.
