BACKGROUND: Assessing the degree of improvement is important for establishing the standard of care provided by an individual orthodontist or tertiary care institution. OBJECTIVE: This study aimed to assess the orthodontic treatment outcomes of patients treated by residents in a postgraduate orthodontic programme at a University in South Africa. DESIGN: Retrospective assessment of orthodontic treatment outcomes using the Peer Assessment Rating (PAR) index. SETTING: Department of Orthodontics at a University in South Africa. Participants Patients who completed fixed orthodontic treatment between May 2016 and May 2021. METHODS: The PAR index was used to assess pre- (T0) and post-treatment (T1) orthodontic study models. Additional outcome measures that were assessed included extraction, non-extraction, orthodontic bracket prescription, impactions, Angle classification and duration of treatment. RESULTS: Seventy-four patients were included in the study, with a mean age of 16 years and 6 months, and a sex distribution of 47 (63.5%) females and 27 (36.5%) males. The mean treatment time was 32 months, with a mean weighted score reduction of 28.1 (86%). The sample had 72 (97.3%) patients categorised as "improved" and 2 (2.7%) as "worse or no different". Of the "improved" patients, 52 (70.2%) were "greatly improved". CONCLUSION: The mean percentage weighted PAR score reduction of 86% for the sample reflects a high standard of care provided by the orthodontic residents at the tertiary care centre.
