Resumen
Objective: To compare the use of the Aesthetic Component (AC) of IOTN and the Child Perceptions Questionnaire (CPQ) in assessing orthodontic treatment need and concern.
Design: Cross-sectional observational study Subjects and methods: The subjects were 204 children aged 10�12 years studying in 10 schools in Bristol, UK. They completed a questionnaire comprising the CPQ and questions regarding orthodontic concern. AC scores as rated by the child and by the calibrated examiner were recorded.
Main outcome measures: CPQ scores were calculated from the responses in the questionnaire. AC scores and responses to questions regarding orthodontic concern were recorded.
Results: The children gave themselves lower AC scores compared to the examiner (p<0.001).
The only section of the CPQ that correlated significantly with Examiner AC was the emotional impacts section (rho=0.151). CPQ scores had a slightly higher correlation with self-perceived AC than Examiner AC. However, the correlations were still very low. The emotional impacts section of CPQ (rho=0.332) and overall CPQ score (rho=0.282) were better than the examiner AC (rho=0.209) at reflecting how bothered the children were by the alignment of their teeth, and how upset they would be if they couldn�t receive orthodontic treatment (rho=0.464, 0.428 and 0.214, respectively). Children with a normative need for orthodontic treatment, based on examiner AC did not have a worse oral health-related quality of life.
Conclusion(s): The CPQ and IOTN AC measure different attributes. There should be a shift towards using quality of life measures to supplement the IOTN in assessing the perceived need for orthodontic treatment.
