Assessing orthodontic treatment outcome of patients treated by orthodontic registrars - using the Peer Assessment Rating index

Background: Orthodontic treatment aims to improve occlusion and aesthetics in patients’ dentition. Assessing the degree of improvement is important to establish the standard of care provided by an individual orthodontist or a tertiary care institution. This study aimed to assess the orthodontic treatment outcomes of patients designated for use in final examinations by registrars in the postgraduate orthodontics program at the University of the Western Cape (UWC). The assessment was performed using the Peer Assessment Rating (PAR) index. Additional outcome measures included extraction, non-extraction, orthodontic prescription, impactions, Angle classification, and duration of treatment. Orthodontic study models and treatment records of patients who met the inclusion criteria were included. The final sample consisted of seventy-five patients with a mean age of 16 years and 6 months and a sex distribution of 47 (63%) females and 28 (37%) males. The PAR index was used to assess the pre- (T0) and post-treatment (T1) orthodontic study models. Additional outcome measures were assessed using the treatment records of the study sample.
