Evaluation of Selection Criteria for Patients Indicated for Fixed Orthodontic Appliance Treatment.

This study aimed to assess selection criteria for patients treated with fixed orthodontic appliance at the College of Dentistry, University of Baghdad, and to set a protocol of treatment in accordance with the Index of Orthodontic Treatment Need (IOTN). Medical records of 120 patients aged 10-30 years old, were retrieved, examined and scored according to IOTN. Results showed that 69% of patients fall within the definite treatment group (i.e. scores 4 and 5), none was in the no need group, 21% in the moderate need group and only about 10% of the sample was in the little need group. Females had the greater prevalence for each score, and the difference was much greater at scores 2 and 3. The criteria for patient selection according to the IOTN-DHC were applicable to Iraqi sample in this study, therefore, it is recommended to use this index to identify patients in need for treatment with some suggested modifications.
