Orofacial pain in young adults and associated childhood and adulthood factors: results of the population study, Wales, United Kingdom.

Objectives: The aim of the study was to investigate the prevalence of orofacial pain (OFP) among young adults (30-31 years old) and to determine the effect of childhood and adulthood risk factors on the occurrence of OFP.

Methods: Prospective cohort study to investigate dental and social effects of malocclusion and effectiveness of orthodontic treatment was conducted in Wales, United Kingdom. At 20-year follow-up 337 subjects aged 30-31 participated (74% from previous follow-up aged 19-20 and 33% from the baseline) and were asked about OFP.

Twenty-year cohort study of health gain from orthodontic treatment: temporomandibular disorders.

Introduction: Temporomandibular disorder (TMD) is a common condition. Studies of TMD in relation to orthodontic treatment did not show an association, but longitudinal studies from adolescence to adulthood are lacking. The aim of this study was to investigate the relationship between orthodontic treatment and TMD with a longitudinal study design.

Malocclusion and temporomandibular disorder: a comparison of adolescents with moderate to severe dysfunction with those without signs and symptoms of temporomandibular disorder and their further development to 30 years of age.

A total of 1018 subjects were examined at the age of 11 years, 791 were reexamined at 15 years, 456 at 19 years, and 337 at 30 years. Anamnestic and clinical recordings of temporomandibular disorder (TMD) were made. Morphology, including calculation of peer assessment rating (PAR) scores, was recorded.
