Significance of association (P) between the number (N) and proportion (%) of subjects (i) without caries experience, with lower and higher caries experience (DMFT and DMFS), and gender, based on 50th percentile of distribution of DMFT and DMFS; and (ii) without, with very low, low, moderate, high and very high caries experience and gender based on DMFT categories used by WHO14
