[Antimicrobial efficacy and alkalizing effect of different calcium hydroxide compounds]

This publication compares the alkalizing effect of various calciumhydroxide compounds and their antimicrobial efficacy. In these experiments aqueous calciumhydroxide suspensions demonstrate the comparably highest alkalization combined with a profound longacting antimicrobial action. At relatively minor alkalization the examined calciumhydroxide cement caused a less profound, but also consistent inhibition of bacterial growth. Samples of calciumhydroxide-containing liners, fillers, and synthetic compounds, although showing a marked alkaline reaction themselves, did, however, not or almost not cause an alkalization of the environment or an inhibition of bacterial growth.
