- 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. RESULTS: The prevalence of OFP was 23% (95% CI: 19%, 28%). Childhood factors, socio-demographic, lifestyle, health behavior factors, history of orthodontic treatment and tooth wear were not associated with OFP. Participants with OFP were more likely to report that their teeth did not fit together properly [odds ratio (OR) = 12.4, 95% CI: 2.7-56.5) and reported previous trauma to the jaws (2.3; 1.3-4.2). Both diurnal and nocturnal teeth clenching and grinding were significantly associated with OFP (3.1; 1.4-7.1). Participants with frequent headaches had increased risk of having OFP (3.7; 1.6-8.4) while having reported 4-10 types of pain in other parts of the body other than the head, was associated with OR = 9.2 (3.7-23.0). An increased tendency to have OFP was seen in those individuals with higher levels of psychological distress (2.3; 1.4-3.9), high score on Life Event Inventory (2.6; 1.3-5.3), depressive symptoms (2.2; 1.2-4.0) and stress (2.2; 1.2-4.0). High self-esteem associated with lower risk of OFP (0.5; 0.3-0.9). CONCLUSIONS: This study shows that OFP is frequently reported by young adults aged 30-31 and supports a multifactorial etiology with factors from many domains, including local mechanical factors, psychological and co-morbidities. However, none of the childhood factors considered in this study were associated with OFP in adulthood.

- 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. Previous history of orthodontic treatment was assessed. Muscular endurance was recorded. The subjects completed four psychological measures. The malocclusion prevalence, occlusal contacts, psychological factors, and muscular endurance in subjects with no recorded signs and symptoms of TMD were compared with those with the most severe dysfunction at 19 years of age. The further development of TMD to 30 years of age was followed. PAR scores were significantly higher in the subjects with the most severe dysfunction. Apart from crowding of teeth, no other significant differences were found between the groups with regard to separate malocclusions, tooth contact pattern, orthodontic treatment, or extractions. A greater proportion of subjects with low endurance were found in those with TMD. Significant associations between TMD and general health and psychological well-being as well as the personality dimension of neuroticism and self-esteem were found. During the period from 19 to 30 years, the prevalence of muscular signs and symptoms showed considerable reduction, whereas clicking showed a slight increase. Locking of the joint showed a decrease from 19 to 30 years. One-quarter of the TMD subjects showed complete recovery. Thus, orthodontic treatment seems to be neither a major preventive nor a significant cause of TMD.
