bjective: There is little information regarding the mesiodistal angulation of permanent teeth
in mixed dentition. The aim of this study was to evaluate mesiodistal root angulation of
reference plane based on the midpoint of the intercuspation of primary canines and permanent

25 degrees of distal root angulation. The maxillary canines were the most distally angulated
teeth, whereas the permanent mandibular canines were vertically positioned. The evaluation of
the anterior maxillary area showed vertical position of permanent lateral, and central incisors
with a slight distal angulation, whereas the permanent mandibular incisors tended to a mesial
radicular convergence. Conclusions: The proposed reference line could be useful in mixed dentition
root angulation evaluation; there was a slight asymmetry in the mesiodistal angulation among
homologous teeth, and also a small variation between the male and the female groups, but no
difference between 8-and 10-year-old children.
