| Abstract | ||
| Microbes are considered as the primary etiologic agents in endodontic diseases. Disinfection of the root canal is obtained by the combined effect of biomechanical preparation, irrigation and intra canal medicament. The aim of the present study was to assess the antimicrobial activity of intracanal medicaments (formocresol and Endosepton) against two micro organisms (Streptococcus mutans and staphylococcus aureus) isolated from 15 necrotic pulps of primary molars indicated for pulpectomy procedure. The samples were cultured, and purified using microbiological evaluation. Broth dilution test was performed in our study by preparing test tubes containing 10 ml of BHI broth (pH. 7) which then inoculated with strains of the tested bacteria and incubated at 37 C° for 24 h. After over night incubaction, ten fold dilution were made in test tubes containing 9 ml of normal saline by adding 1 ml of the inoculum to the first tube . Then from dilution 10-1 , 0.1 ml of cell suspension was added to 9.9 ml of formocresol and endosepton, then 0.1 ml was taken and spread on duplicates of BHI agar plates at different intervals and incubated aerobically for 24 h. at 37 C°. Colonies on the plates were counted after incubation and CFU/mL (colony forming unit) was calculated. Our results indicating that there were no significant differences between the intracanal medicaments, but there were high significant differences between the intervals time of the study. We concluded that both materials had great antibacterial effect against the pathogens commonly isolated from necrotic pulpal tissue of primary teeth. | ||
