Objective and subjective need for orthodontic treatment in Stockholm County.

The objective and subjective need for orthodontic treatment according to a modified version of the treatment priority index of the Swedish National Board of Health and Welfare (index scores 0 to 4), was studied in 1281 children and teenagers, aged between 8 and 16 years and living in the Stockholm area. Furthermore, differences between different parts of the Stockholm County with respect to need for orthodontic treatment, and the subjective demand for treatment were also recorded. Five areas with varying population structures were studied.
