Abstract
Aims and Objectives:In recent years, researchers have focused on finding methods of eliminating caries and white spot lesions under orthodontic bands without requiring patient cooperation. One of the effective and preventive strategies is the addition of antibacterial and remineralizing agents to the band cement. However, modifying the cement should not lead to microleakage and weakening of its mechanical properties. This in vitro study represents a continuation of our previous work of investigating the retentive strength of orthodontic bands cemented with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified glass ionomer cement (GIC).Material and Methods:60 extracted human premolars were randomly divided into two groups (n = 30). In group 1, stainless steel bands were cemented with GIC. In group 2, a novel dental caries-preventive material, CPP-ACP, was incorporated into the GIC for cementing. The microleakage of each group was measured by the fluid filtration method.Results:Results showed no statistically significant difference in microleakage of either group (GIC and CPP-ACP-modified GIC).Conclusion:We concluded that 1.56% w/w CPP-ACP can be incorporated with GIC for cementing orthodontic bands without promoting microleakage.
