Antibacterial Activity and Physical Properties of Conventional Glass-ionomer Cements Containing Chlorhexidine Diacetate/Cetrimide Mixtures

ABSTRACT Statement of the Problem: Hand excavation instruments are not as efficient as that with rotary burs in atraumatic restorative treatment (ART). Purpose: To evaluate the antibacterial activity (ABA), microhardness numbers (VHN), and cumulative fluoride releasing (CFR) patterns of conventional GICs (Fuji IX (FX) and Ketac Molar (KM)) containing chlorhexidine diacetate/cetrimide mixtures (2.5%/2.5%) (AB). Materials and Methods: The powders of ABs were added to powders of FX and KM selected as experimental groups (EXPs). FX and KM were assigned as controls (CNTs). ABA against S.mutans (MS) and L.casei (LB) were examined between 1–90 days. VHN were calculated after 24 hours and CFR patterns measured between 1–30 days. Analysis of variance was used for comparison (p
