INTRODUCTION: This trial aimed to longitudinally evaluate the effect of the treatment of transverse maxillary deficiency using rapid palatal expansion (RPE) on self-perceived oral health-related quality of life (OHRQOL) in children.
METHODS: Eighty participants aged 8-10 years with transverse maxillary deficiency and bilateral posterior crossbite were randomly assigned to 2 groups (n = 40 each): a group treated with RPE using hyrax-type appliances and a nontreated control group. OHRQOL was assessed by using the Child Perceptions Questionnaire for 8-10-year-olds at 4 times: before RPE, during RPE (T1), at the end of RPE (T2), and 1 month after the appliance removal (T3). Generalized mixed models were used for data analysis (α = 0.05).
RESULTS: Both groups exhibited similar demographic characteristics and OHRQOL scores at baseline. All participants completed the study. RPE had a time-dependent effect on OHRQOL. At T1 and T2, this therapy is expected to increase the overall OHRQOL scores by 1.17 times (ie, ∼17% increase; T1 95% confidence interval [CI], 1.08-1.26; T2 95% CI, 1.09-1.27; P = 0.001). In contrast, the overall OHRQOL scores at T3 are expected to be 0.28 times the baseline scores (ie, ∼72% reduction; T3 95% CI, 0.26-0.31; P = 0.001). All individual domains of the OHRQOL evidenced a positive impact of treatment at T3 (P = 0.001). Only the oral symptoms and social well-being domains showed a significantly negative impact of the treatment at T1 and T2.
CONCLUSIONS: Correction of the transverse maxillary deficiency by RPE in children aged 8-10 years improves OHRQOL. There is a temporary worsening of OHRQOL during the treatment of this condition using RPE.
REGISTRATION: This trial was not registered.
PROTOCOL: The protocol was not published before trial commencement.
