Introduction: This study investigates buccolingual crown size of the maxillary and mandibular incisors in patients with permanent
mandibular canine/s impaction.
Material and methods: Dental models of 43 subjects diagnosed with mandibular canine/s impaction (Impaction Group) were
compared with those of 86 subjects of a control reference sample (Control Group). Independent t-test was used to determine the
association between mandibular canine/s impaction and the maximum buccolingual crown diameter of the incisors. Results: Only
mandibular central incisor and lateral incisor had statistically significant differences (P<0.05) between the groups.
Conclusion: Subjects with mandibular canine/s impaction appear to be characterized with buccolingually wider incisors. It raises the
possibility that mandibular incisors teeth size helps in prediction of mandibular canine impaction, early during the mixed dentition.
