Abstract

Aim:  To evaluate the antibacterial efficiency of 2%Chlorhexidine gel, Metapex, Calcium hydroxide powder mixed with 2% chlorhexidine solution and Calcium hydroxide paste as intracanal medicaments against E.faecalis bacteria.  Materials and Method: 80 single rooted human mandibular premolar teeth were collected. All the teeth were decoronated and biomechanical preparation was completed. Root canal space of all the teeth were infected with pure culture of E.faecalis bacteria and were randomly into four groups with 20 teeth per each group. Group A: 2%Chlorhexidine gel, Group B: Metapex, Group C: Ca(OH)2 powder mixed with 2% chlorhexidine solution, Group D: Calcium hydroxide paste, were used as intracanal medicaments. Lentulo spiral instruments were used to place the intracanal medicaments in the root canal space and the teeth were temporarily restored for 7 days. Later, intracanal medicaments were completely removed using canalbrush and root canal space were dried. Dry sterile paper points were used for culture tests from all samples and the number of CFU were counted. Results: Statistical analysis by One-Way ANOVA showed significant difference in the antibacterial efficiency between the four groups. P-Value is =0.0001.  Conclusion: 2% Chlorhexidine gel showed the highest antibacterial efficiency compared to other intracanal medicaments used in this study.
