In vitro investigations on the antimicrobial effect

The antimicrobial effect of ApexCal was examined in comparison to that of Calxyl, Calcipulp and calcium hydroxide using agar diffusion tests. This investigation did not establish any difference in the materials tested. As expected, the antimicrobial effect was limited to a narrow area of approx 0.5 to 1 mm in the immediate vicinity of the samples.

Agar diffusion test of ApexCal: An inhibition zone (C) is visible adjacent to the ApexCal sample (D). The whitish aureole (B) is an artefact caused by the diffusion of the material along the Petri dish. A: Bacteria lawn (Lactobacillus)
