Wilson NJ, et al. - In order to gain insights into the ways whereby oral health outcomes can be improved for people with intellectual and developmental disability (IDD), a population with poor oral health and requirement of support to maintain optimal oral health outcomes, researchers analyzed the existing evidence addressing this topic from five electronic databases in this scoping literature review. Findings revealed a small number of approaches and interventions in this regard. A crucial role of caregivers in the provision of oral health support was emphasized in the identified studies and this highlights that educational interventions for caregivers are effective. Frequently, a required and effective method of oral healthcare provision in cases of more severe IDD and/or dental-related behavioural problems was dental treatment under general anaesthesia. The limited access of such population to oral care services can successfully be enhanced via strategies such as outreach and exclusive oral health services. Experts concluded that success with a uniform approach to supporting oral health for people with IDD is unlikely. In order to meet the different requirements of such populations, their caregivers and service context, the necessity of a system-based approach was realized.
