A new Norwegian index of orthodontic treatment need related to orthodontic concern among 11-year-olds and their parents.
A new index of orthodontic treatment need was introduced in Norway in 1990. On a morphologic and functional basis the four groups very great (A), great (B), obvious (C) and little/no (D) need were defined for social insurance refunding. The purpose of the present study was to investigate to what extent the new index corresponded with orthodontic concern among potential orthodontic patients and their parents. Of 104 randomly selected fourth grade children, 99 (48 girls, 51 boys, mean age 10.7 yr) presented themselves for clinical examination and interview. One parent was asked to accompany the child, and 93 parents attended. On the basis of clinical examination, morphologic measurements on study casts, and X-rays, the children were allocated to one of the four groups defined by the index. In separate questionnaires the children and the parents were asked to assess satisfaction with own/child's dental arrangement and desire for orthodontic treatment. The interview data were transformed into a composite measure representing orthodontic concern. The results indicated that orthodontic concern was significantly related to index group. For the individuals who expressed concern the new index seemed to be meaningful for allocation of public subsidies, as most individuals (85%) who expressed concern exhibited malocclusions fulfilling the criteria for receiving public subsidies of treatment costs. However, more than 50% of the individuals allocated to group B (great need) did not experience a need for treatment.
