Clinical evaluation of the antibacterial action of different intracanal medicaments

Abstract EN

Aim of the study: To evaluate the antibacterial effectiveness of different intracanal medicaments.

Material and method: One hundred and twenty anterior opened necrotic teeth with no apical radiolucencies were chosen for this study.

Endodontic treatment was performed to the teeth which were medicated between the appointments by different intracanal medicaments (Tricresol formalin, formocresol, 2% acetic acid, CMCP, calcium hydroxide, and normal saline as control).

The decrease in the bacterial flora of these teeth was monitored during the treatment appointments by swabbing the root canals and culturing the swabs on blood agar culture media.

Results: The teeth medicated by tricresol formalin formocresol and 2% acetic acid experienced the most decrease in the bacteria count and showed the highest negative cultures.

CMCP was next and then calcium hydroxide and lastly normal saline.

The chemo mechanical debridement of the root canals was effective in eliminating most of the bacterial flora but not to the degree of sterility.

Conclusion: Two percent acetic acid can be an efficient intracanal medicament
