OBJECTIVE: To evaluate the orthodontic treatment outcome among patients with non-syndromic unilateral cleft lip and palate using the Peer Assessment Rating (PAR) index. MATERIALS AND METHODS: The retrospective study comprised a sample of 80 patients with unilateral cleft lip and palate (39 males and 41 females) with complete pretreatment and posttreatment orthodontic records. The patients were divided into two groups according to the treatment modalities. Group 1 (n = 55), nonsurgical (consisted of patients treated with comprehensive orthodontics) and Group 2 (n = 25), surgical (with presurgical orthodontics followed by maxillary advancement orthognathic surgery). PAR score was evaluated on pretreatment and posttreatment study models for both groups. RESULTS: The mean percentage change for the weighted PAR score of Group 1 and Group 2 was 76.79 ± 20.27% and 82.37 ± 11.38%, respectively. Out of the total sample of 80 cases; 62 (77.5%) cases were “greatly improved,” 16 (20%) cases were “improved,” and 2 (2.5%) showed “worse/no improvement.” Nearly 72.5% of cases in Group 1 and 88% in Group 2 were greatly improved. CONCLUSIONS: The reduction in PAR score in both groups was satisfactory as more than 70% of the patients were in the greatly improved category. The results of the PAR index revealed a high occlusal outcome of orthodontic treatment rendered by the department for patients with unilateral cleft lip and palate.
