The prevalence of adult onset idiopathic isolated focal dystonia in Ireland is higher than that recorded in many similar service-based epidemiological studies but is still likely to be an underestimate. The low proportion of individuals with blepharospasm may reflect reduced environmental exposure to sunlight in Ireland. This study will serve as a resource for international comparative studies of environmental and genetic factors in the pathogenesis of the disorder.

In the cohort examined: AR and OR differed significantly for malocclusion groups. The prevalence of clinically significant TSDs did not differ significantly between surgical and non-surgical groups although the highest percentage of clinically significant TSDs was recorded for AR in Class II and Class III surgical cases. AR and OR were closely related.

Objective To examine the distribution of interdisciplinary clinics for hypodontia patients in the UK and to assess the provision of orthodontic-restorative care for hypodontia patients in units where this service is and is not available.Design Prospective, online-questionnaire.Setting Hospital orthodontic departments in the UK.Participants In total, consultants from 92 orthodontic departments completed the questionnaire.Methods Orthodontic consultants were asked to complete a questionnaire regarding the provision of orthodontic-restorative care for hypodontia patients in their units.Results Overall, 100% of teaching hospitals and 51% of district general hospitals (DGHs) that responded have an interdisciplinary clinic for hypodontia patients. In 51% of units, the majority of patients assessed on the interdisciplinary clinic undergo their restorative care at the same secondary care unit. In 59% of units where an interdisciplinary clinic is not available most of the restorative care for hypodontia patients is provided by the GDP, whilst in 38% of units a specialist restorative dentist in another secondary care unit provides most of the restorative care.Conclusions The provision of an interdisciplinary clinic for hypodontia patients varies amongst hospital units throughout the UK. The provision of orthodontic-restorative care for hypodontia patients also varies between these units.
