Adolescents’ Perception of Dental Arrangement and its Influence on Oral Health, Function, Self-esteem and Everyday Life

There is a great need to develop a new kind of instrument for assessment of orthodontic treatment need. Such an instrument or index should apart from purely morphological aspects of the dentition also include consequences of malocclusions on oral health, function and psychosocial wellbeing. Through this project based on both qualitative and quantitative studies we will develop and test an instrument for assessment of dental arrangement-related everyday life issues, focusing on self-esteem and experiences regarding oral health and function. We also investigate the impact of dental disarrangement and orthodontic treatment on self-esteem, oral health and function and everyday life in adolescents.

The new instrument will comprise a questionnaire with items extracted from focus group interviews with teenagers complemented with items covering global health perception. The questionnaire is distributed to randomly selected children, 13-year of age living in the county of Uppsala. The results of the questionnaires will be linked to data on orthodontic diagnoses obtained from their general dentist´s records.

Associations between subjective treatment need (based on the new instrument), oral health related quality of life and professional assessment based on current treatment need indices will be calculated.
