Evaluation of Postorthodontic Changes in the Treatment of Cleft Lip and Palate Patients Using the PAR Index

Abstract

Objective: To evaluate dental changes in cleft patients after undergoing orthodontic treatment for at least 2 years. Hypothesis: The dental change would decline significantly after 2 years of completing orthodontic treatment. Design: This is a retrospective study. Patient: Eighteen repaired cleft lip and palate patients from the Faculty of Dentistry, KhonKaen University, Thailand, participated in this study. Mean Outcome Measures: A dental model with before treatment (T0), completed treatment (T1), and retention period (T2) data was analyzed using the peer assessment rating (PAR) index. Result: The results showed that the PAR score improved enormously after treatment; from T0 to T1, it was 34.00 ± 10.01 to 4.67 ± 2.47, and there was a reversion in the retention period. There was statistical significance between T0, T1, and T2, with P values
