Morphometric variations and nonmetric anatomical traits or anomalies of the primary molar teeth, plus the molars' size thresholds for sex identification

Table 6 The evaluation of the symmetry between the prevalences of the traits on the right versus left sides. The P values are calculated using the McNemar test
