Inclusion Criteria

Inclusion criteria common to all groups: children about 9 years of age with intact primary canines and molars; without prior orthodontic interventions; with preventive / interceptive orthodontic needs or space supervision. Participants may not have chronic or systemic diseases that affect dental resorption or formation.

Exclusion Criteria

patients with chronic or systemic diseases that affect dental resorption or formation, participants with previous orthodontic treatment, because the pattern of dental resorption may be altered and / or participants with exfoliated canines or primary molars.

Primary Outcome Measures

Name	Time	Method
To evaluate the pattern of root resorption rate / speed of primary teeth, through the comparison of panoramic radiographs (baseline and after 1 year of treatment), from the measure of root resorption (quantitative) and scores (qualitative)

Secondary Outcome Measures

Name	Time	Method
To evaluate the influence of root resorption of primary teeth on the formation/eruption of sucessor permanent, through the comparison of panoramic radiographs (baseline and after 1 year of treatment), assessing root formation of permament teeth (Nolla stage) and measuring the distance from the cusp tip to the occlusal plan.
