Sažetak
Calcium hydroxide preparations Ca(OH) 2 are used as water solutions, putly, liner, cement or arteficial material. The therapeutic
effect of each medicaments depends on physical and chemical haracteristic of additional components. The aim of the paper is to research the sensitivity of Streptococcus faecalis and Candida albicans to different water solution concentrations o f 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 o f water solutions of Ca(OH)2. Preparations, created as described were incubated aerobically at 3TC in the period o f 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 occured with the concentration o f 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 occured with the concentration o f Ca(OH) 2 solution from 1023,20 x 10'3 molldm3 and pH 12,84. The difference in the sensitivity o f the examined microorganisms at the same concentrations of Ca(OH) 2 solution was observed.
