Small upper lateral incisors in patients with palatally impacted canines may contribute to inter-arch tooth size discrepancies.
To compare the Bolton ratios in female patients with and without unilateral palatally impacted canines.
The pretreatment dental casts of 30 female patients with unilateral palatally impacted canines (Impaction group) and 30 female patients without palatally impacted canines (Control group) were used. The latter were matched for age and incisor malocclusion with the Impaction group. The anterior and overall Bolton ratios were calculated for each group.
Although the total width of the upper anterior teeth in the Impaction group was significantly smaller than the total width of the upper anterior teeth in the Control group (
Females patients with palatally impacted canines may not have more inter-arch tooth size discrepancies than female patients without palatally impacted canines.
