Commentary. Antibacterial activity and physical properties of conventional glass-ionomer cements containing chlorhexidine diacetate/cetrimide mixtures.

摘要

There are many clinical indications for which the use of conventional glass-ionomer cement (GIC) restorative materials would be advantageous. One such indication is the Atraumatic Restorative Treatment (ART) technique. However, ART is usually performed in situations where state of the art dental equipment is not available and therefore the outcomes of treatment rarely include the total elimination of disease causing bacteria. The purpose of this study is to determine whether the addition of antibacterial agents can reduce the possibility of secondary caries without significantly reducing the fluoride-releasing capacity or deteriorating the physical properties of the glass-ionomer restorative material. This study tested antibacterial activity, microhardness, and cumulative fluoride-releasing patterns of two conventional GICs (Fuji IX and Ketac Molar) containing chlorhexidine diacetate/cetrimide mixtures.
