[The antimicrobial efficiency of aqueous solutions of calcium hydroxide on Streptococcus mutans, Streptococcus faecalis and Candida albicans, in vitro].
Calcium hydroxide preparations Ca(OH)2 are used as water solutions, putly, liner, cement or artificial material. The therapeutic effect of each medicaments depends on physical and chemical characteristic of additional components. The aim of the paper is to research the sensitivity of Streptococcus faecalis and Candida albicans to different water solution concentrations of calcium hydroxide. As solid plates, Bacto-Mitis-Salivarius agar was used for S. mutans, Torlak blood agar for S. faecalis and Sabourand agar "Torlak" for C. albicans. The holes were drilled in solid plates and were filled by 0.2 ml of water solutions of Ca(OH)2. Preparations, created as described were incubated aerobically at 37 degrees C in the period of 48 hrs. Results were read after 24 as well as after 48 hrs. The examined solutions of Ca(OH)2, revealed the highest antimicrobic effect after 24 hrs. The result remained unchanged even after 48 hrs. The inhibition of S. mutans growth on the solid plate occurred with the concentration of Ca(OH)2 solution from 271.18 x 10(-2) mol/dm3 and pH 12.76. The growth of S. faecalis at the solid plate was inhibited with the concentration of 3335.21 x 10(-3) mol/dm3 and pH 12.82. The inhibition of C. albicans growth on solid plate occurred with the concentration of Ca(OH)2 solution from 1023.20 x 10(-3) mol/dm3 and pH 12.84. The difference in the sensitivity of the examined microorganisms at the same concentrations of Ca(OH)2 solution was observed.
