Background: Poor oral health is common in adults with intellectual disabilities leading to risk of mouth and lung infections. Yet, little is known about the benefits of preventative oral health programs.
Objective/hypothesis: This prospective longitudinal experimental mixed methods study evaluated the efficacy of an oral health program aimed at improving knowledge and behaviours in adults with intellectual disabilities living in supported housing.
Methods: A 90-min training session was provided to residents and their staff at 12 houses (56 residents; 67 staff). Follow-up training sessions (at 1 week, 1,2,3 months) were tailored to the learning abilities, behavioural/physical challenges, and independence of residents. Outcome measures were collected pre, 1, 2 and 3 months (n = 36): dental exam, plaque index, gingival signs, tongue coating index and behavioural rating scale. At 3 months, support workers (n = 10) and residents (n = 19) were interviewed. Residents' interviews were supported by Talking Mats®.
Results: Most residents (94%) required support for oral cares; with 63% fully dependant on their support workers. 24 (63%) residents had significantly improved plaque scores at 3 months (p < .001). Resident interviews were restricted by communication competency but supported interviews indicated positive responses to 3-sided toothbrush 91%, interdental brush/flosser 60%, and mouthwash 100%. Support worker interviews revealed perceived health and social benefits including fresher breath and benefits of routines.
Conclusions: Oral health programs for adults with intellectual disabilities living in supported housing are well received by staff and residents, leading to changes in oral care routines and measurable changes in oral health.
