Determination of the sensitivity of the microflora of periodontitis teeth to furacilin

Abstract

Sensitivity to furacilin of streptococcus isolated from periodontitis teeth was studied in 38 patients by serial dilution and in 34 patients using diffusiometric method. The material was taken from the root canal with sterile turunds on root needles. The crops were sown on a Kitt—Tarozzi medium and Petri dishes with 5% blood agar. Incubation was carried out at 37* for 24-28 hours. Isolation of pure streptococcal cultures was performed using the usual method. By the method of serial dilutions, it was proved that the sensitivity of the studied streptococcus cultures has a significant range. Furacilin concentrations in dilutions of 1:40,000 and 1:160,000 were optimal. The bacteriostatic effect was found on 28 of 38 cultures.
