Pharmacological behaviour support for adults with intellectual disabilities: Frequency and predictors in a national cross-sectional survey.

People with ID report a diverse range of support use, with many using GA or CS, particularly oral sedation, for dental treatment. This highlights a need for training and governance for dentists who provide this care. Patients who present with challenging behaviour, oral problems and, interestingly, difficulty with expressive communication are more likely to report use of pharmacological supports. The above has implications for dental service design and delivery for this population.
