Abstract:

Aim: Caries recurrence under restorations considered one of the main causes for restoration replacement. The aim of this study was to evaluate the anti-cariogenic property (fluoride ion release and its antibacterial properties) among four types of glass ionomer cements used as a permanent filling of caries cavities. Materials & Methods: Four types of glass ionomer cements were used in this study such as Fuji IX (GC, Japan) - conventional glass ionomer cement; Fuji II LC (GC, Japan) �?? resin modified glass ionomer cement (RMGIC); Dyract AP (Dentsply, Konstanz, Germany) - polyacid-modified composite resin (compomer) and; Ketac N100 (3M ESPE St. Paul, MN, USA) - nano-filled resin-modified GIC. Six wells (7 mm diameter and 3 mm thickness) were punched in the Muller-Hilton agar plates and filled with the four types of GIC restorative materials. The antibacterial activity of each material was evaluated against the Streptococcus mutans after day 2, 7, 14 and 30. Results: All types of GIC restorative materials developed antibacterial activity and bacterial inhibition zone but size of these zones decreased by time to be the smallest at day 30. Conclusion: The best one developed antibacterial activity was Fuji IX - conventional glass ionomer cement all over tested time, followed by Ketac N100 - nano-filled resin-modified GIC while the least one was Dyract AP (Dentsply, Konstanz, Germany) - polyacid-modified composite resin (compomer). If the antibacterial property is the most important for dentist regardless physical & mechanical properties of GIC restorative material, the first choice should be conventional GIC e.g. Fuji IX.
