Sibling correlations with adjustment for age, sex, and other covariates showed the highest degree of similarity in incisor width, followed by malalignment, overjet, overbite, crowding, spacing, and crossbites. The smallest intrafamily correlations were observed in the variables in buccal segment relationship, especially in neutroclusion and idealized occlusion pattern.
