The provision and outcome of orthodontic services in a Norwegian community: a longitudinal cohort study.
In a systematic child dental care system, professionals, consumers, and purchasers have a common interest in ensuring that provision and outcome of orthodontic care fulfill the goals of the service and the public's expectations. The purpose of this prospective study was to examine whether treatment was in fact provided to children with a normative treatment need, and also to assess the outcome of treatment. The baseline data were established for a sample of 83 11-year-olds before decisions about orthodontic treatment had been made, by recording the individuals' orthodontic concern as reported in questionnaires and their occlusal condition according to an index of orthodontic treatment need (NOTI). At re-examination at the age of 16 years, it was also recorded whether the individual had received orthodontic treatment. Most individuals (83%) with a normative need had been treated as well as some individuals without need but who had expressed orthodontic concern. Treatment had resulted in occlusal improvement ('health gain') in most patients, and generally this improvement paralleled a decrease in concern. The goals of the orthodontic service seem to have been fulfilled to the extent that residual treatment need was infrequent. The high treatment rate (63%) and standard may explain why all individuals, both treated and untreated, expressed satisfaction with their dental appearance at 16 years of age.
