title: Combining normative and psychosocial perceptions for assessing orthodontic treatment needs.
abstract: Whereas perceptions of malocclusion by the public are mainly subjective, currently orthodontic treatment needs are predominantly determined using normative need. There are considerable differences between normative and subjective perceptions of orthodontic need. Yet clinical measures determine current provision of orthodontic services, whereas subjective oral health-related quality of life (OHRQoL) measures are seldom used and play a small part in need assessment despite predicting perceived need. The sociodental approach to assessing orthodontic treatment needs overcomes deficiencies of the sole use of normative need. It is a gradual integration process, estimating orthodontic needs by combining normative and psychosocial perspectives, as well as considering behavioral factors affecting outcomes of orthodontic treatment and scientific evidence about the effectiveness of interventions. To be appropriately used in needs assessment, an OHRQoL measure should provide condition-specific estimates of the impact of malocclusion on daily life. The sociodental approach attempts to replicate the characteristics of good clinical practice using a structured, rational, and coherent system for assessing orthodontic needs and, therefore, is a useful tool in planning oral health services.
