The values are presented as means ± standard deviations. The values with different superscript letters within the same column are significantly different at p < 0.05.
Group 1, control (RMGIC-sound dentin assembly specimens); Group 2, RMGIC-artificially demineralized dentin assembly specimens (CAD specimens); Group 3, RMGIC to demineralized and then CPP-ACP remineralized dentin assembly specimens (remineralized CAD specimens); LSD, least significant difference; RMGIC, resin-modified glass ionomer cement; CAD, caries-affected dentin; CPP-ACP, casein phosphopeptide-amorphous calcium phosphate.
