Oral Health Related Quality of Life measured with Child Perceptions Questionnaire 11-14 short form- change before and after orthodontic treatment and at matched time points in an untreated population
Child Perceptions Questionnaire (CPQ) 11-14 short form is a common instrument measuring Oral Health Related Quality of life (OHRQoL) in children and adolescents. It is a generic instrument, measuring all aspects of OHRQoL.
At start of study, 1 year after start of study, at study completion (an average of 2.5 years), 1 year after study completion
Oral Health Related Quality of Life measured with Psychosocial Impact of Dental Aesthetics Questionnaire - change before and after orthodontic treatment and at matched time points in an untreated population
Psychosocial Impact of Dental Aesthetics (PIDAQ) is an instrument measuring orthodontic specific aspects of OHRQoL.

500 12-19 year olds with malocclusion, defined as IOTN-DHC grade 3, 4 or 5. The adolescents are consecutively recruited new patients at three orthodontic centers; Center for Orthodontics and Pediatric Dentistry, Norrköping, Public Dental Service Östergötland; Department of Orthodontics, Folktandvården Stockholms län AB, Folktandvården Eastmaninstitutet, Stockholm, Sweden and Department of Orthodontics, Malmö University, Malmö, Sweden. Patients are examined at the first visit at the orthodontic department, before any orthodontic treatment is begun.
175 12-19 year olds without malocclusion, defined as IOTN-DHC grade 1 or 2. Patients are consectively recruited adolescents examined at their general dentistry clinic.
Group 1 is exposed to malocclusion and orthodontic treatment. However, the inclusion in the study does not affect the treatment since it is an observational study. The exposure of group 2 is no malocclusion, no orthodontic treatment.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
