Factors influencing the decision about orthodontic treatment. A longitudinal study among 11- and 15-year-olds and their parents.
The aims of the study were to evaluate the attitude towards orthodontic treatment among 11-(T1) and 15-year-old children (T2) and their parents, to present the distribution of referral rate and treatment uptake by a treatment need index assessed at T1 and to elucidate factors influencing the decision about orthodontic treatment in the period from T1 to T2. A group of 359 children and their parents answered separate questionnaires at T1, and 293 families responded to a follow-up study 4 years later. For the clinical examination, 224 children participated after exclusion of children in active treatment. The dental study casts were assessed by the Index of Orthodontic Treatment Need (IOTN). The mean referral rate was 56%, with a variation from 40% to 71% among different dental clinics. About 44% of the children had completed or were undergoing orthodontic treatment at T2. No significant sex differences among referred and treated children were discovered. Aesthetic motives were the most frequently reported subjective reason for orthodontic care. The untreated group expressed diminishing treatment desire in the follow-up period. The logistic regression analysis selected Dental Health Component (DHC) grades as a strong predictor for treatment uptake, followed by parents' concern and attitude to braces, while the 11-year-olds' own orthodontic concern was less significant. Children in the untreated group with late treatment decisions (T2) were best predicted by Aesthetic Component (AC) changes from T1 to T2. The results indicate that dentists play a key role in determining orthodontic treatment levels. High referral rates secured low risk of denying care to some patients. Treatment decision may be guided by the orthodontist. However, individual variation in attitude and desire influence treatment uptake even among children with great need.
