Objective.  : The purpose of this in vitro study was to investigate antimicrobial activity of calcium hydroxide (CH)  in  combination  with  chlorhexidine gluconate (CHX),glycerine,  chitosan  and  saline  against Enterococcus faecalis and Candida albicans.

Study design: Antimicrobial activity was determined using agar diffusion test. Standard well  in the cultivated agar plates were filled with one of the calcium hydroxide preparations and control agents. The zones of microbial inhibition were measured after incubation period.

 Results. : The  combination  of  Calcium  hydroxide  with chlorhexidine  demonstrated  most  antibacterial  activity  of  all  other  preparations. All  the  tested  groups  had  significant  antimicrobial  action  against E faecalis  and  C albicans.

Conclusion : Antimicrobial  activity  of  Calcium  hydroxide  may change with  the  type  of  the  vehicle.
