Abstract | AIMS: To assess the prevalence rates and risk factors of anterior disc displacement with reduction (ADDR) and symptomatic hypermobility in a large sample of children and teenagers. Prevalence rates were also established in samples of young adults and adults. METHODS: Children from 7 Dutch primary and secondary schools (n = 1,833) aged 4 to 18 years (mean age +/- SD 10.8 +/- 3.9 years), 220 dental students aged 19 to 30 years (mean age +/- SD 21.9 +/- 3.6 years), and 100 dental school employees more than 30 years old (mean age +/- SD 43.5 +/- 9.8 years) were examined. The presence of ADDR or symptomatic hypermobility was scored using well-defined clinical criteria. For the children only, an additional standardized oral history and clinical examination were performed to assess possible risk factors. Odds ratios ( ORs) were calculated with the use of logistic multivariate regression analysis. RESULTS: The prevalence rate of ADDR in at least 1 of the 2 joints increased during childhood and adolescence and stabilized into adulthood at about 26.6%. In children and teenagers, besides age (OR = 1.06 for boys, OR = 1.23 for girls), risk factors for ADDR were a history of orthodontics (OR = 1.57), an increasing overbite (OR = 1.15), and protrusion (OR = 1.12). In children and teenagers, the prevalence rate of symptomatic hypermobility was higher for girls (13.8%) than for boys (8.2%). Besides gender (OR = 2.07), risk factors for symptomatic hypermobility were race (OR = 2.61 for non-Caucasians), masticatory muscle pain (OR = 1.95), and increasing maximum mouth opening (OR = 1.08). CONCLUSION: In children and teenagers, ADDR and symptomatic hypermobility have different prevalence rates and risk factors.
