ABSTRACT


Aim

To evaluate the presence of root resorption in the lateral incisor after active orthodontic treatment in the early mixed
dentition.

Methods

Twenty-six children treated at the Children's Clinic of the Schulich School of Medicine and Dentistry at the
University of Western Ontario were examined radiographically for lateral incisors root resorption before and after early active treatment
to align upper incisors (2x4 appliance). In addition, canine inclinations to the midline and to the long axis of the lateral incisor as well as
the most medial position of the canine crown were measured as potential risk factors for root resorption.

Results

8 (4) of the
lateral incisors exhibited root resorption and the mean crown-to-root ratio of these teeth was significantly higher than that for lateral
incisors not exhibiting root resorption. Similarly, mean canine inclinations to the midline and to the long axis of the lateral incisor were
also significantly higher for the root resorption group. No association could be found between the most medial position of the canine
crown and root resorption in the lateral incisor.

Conclusion

This study showed that active orthodontic treatment in the early mixed
dentition does not increase the risk for root resorption in the lateral incisors as long as the clinician takes into consideration canine
inclinations and their potential effect on root resorption. Limitations inherent to radiographic assessment are acknowledged.
