To evaluate differences in cooperation of adolescent patients in active orthodontic treatment between those who received one phased treatment (no prior interceptive or early treatment) and two phased treatment (prior interceptive or early treatment and subsequent corrective treatment). A prospective cohort study was carried out in 132 patients undergoing orthodontic treatment between 10 and 17 years old at CES University Dental Clinics and in 9 private practices in Medellín Colombia; two groups of 66 patients were defined; one that received two phased treatment and one that received one phased treatment. The Orthodontic Patient Cooperation Scale (OPCS) was applied to all individuals every three months during the first year of treatment in order to assess cooperation. Statistical differences between both groups were assessed using the SSPS® software program. Significantly greater cooperation (M = 4.6) was observed in patients who had received two phased treatment compared with those who were only subjected to one phased treatment (M = 2.3). Patient cooperation during orthodontic treatment does not seem to be affected by two phased treatment and to the contrary seems to have a positive impact when comparing it with individuals with one phased treatment. The most important factors found to influence cooperation were correlated with attitude, interest and commitment to treatment, patient and parental motivation. The OPCS scale proved to be useful for evaluating cooperation and making comparisons with other studies.

KEY WORDS: Non-cooperative patients, interceptive orthodontics, OPCS, malocclusion.
