The heritability of maxillary arch length (71.26%) was higher than the mandibular one (31.33%). The intraclass correlation coefficients were similar in dental crowding between MZ and DZ, with the lower in DZ. Low heritability of dental crowding was found in both maxillary (4.73%) and mandibular (10.3%) teeth.
