Abstract

Aim. The aim of this study was to compare the antimicrobial efficacy of cysteamine, calcium hydroxide[Ca(OH)2], triple antibiotic paste (TAP), chlorhexidine (CHX) and their combinations against Enterococcus faecalis (E. Faecalis).

Methods. The E. Faecalis eradication capacity of cysteamine, Calcium hydroxide (Ca[OH]2), TAP, CHX, and their combinations was tested on E. Faecalis by Kirby Brauer disc diffusion method.

Results. Cysteamine in combination with TAP was able to completely eradicate E. Faecalis within 24 hours. Ca(OH)2 was unable to show its effect on E. Faecalis in the given time.

Conclusion. Cysteamine increased the E. Faecalis eradicating capacity of TAP and also showed positive results when used in combination with Ca(OH)2, which if used alone was unable to show any action in 24 hours.
