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

Table 3 Descriptive statistics and 95% CIs for the mesiodistal and buccolingual dimensions of the teeth (mm) after merging the right and left sides. The P values are calculated using the t-test
