aANOVA with overall p value reported. Statistically significant differences were followed up with Tukey multiple comparisons: p < 0.05 compared with *N-N or δN-Y.
bChi-square statistic.
AMR: active carious lesion, missing due to caries or restored due to caries
dmft: number of decayed, missing or filled teeth.
