Background: People with intellectual disabilities (ID) typically have poorer oral health. Oral diseases have a microbiological origin, and thus, dental plaque control (DPC) is key to safeguard their oral health. Methods: A structured search strategy was applied to screen oral health promotion initiatives for DPC among children and adolescents with ID following PRISMA statements. Qualitative and quantitative analyses were performed. Results: From 1,455 citations, 22 studies informed this review. Seven studies related to mechanical interventions and 13 to chemical interventions. Qualitative analyses found conventional toothbrushes were less effective than modified toothbrushes but quantitative analyses were conflicting. Of the nine studies that compared chlorhexidine to placebos, seven reported chlorhexidine was more effective than placebos. Meta-analysis favoured chlorhexidine to placebos (p < 0.0001, 95% CI 0.34-0.63). Conclusions: Both mechanical and chemical interventions are effective for DPC. It is unclear whether they are alternative means for DPC or whether they are best employed together.

Background: A visual-verbal integration model (VVIM) was used to train parents and their children with intellectual and developmental disabilities (IDD) to dispense a pea-sized amount of fluoridated toothpaste, aiming to balance the occurrence of dental caries and fluorosis. Method: Participants were 370 pairs of IDD preschool children and their parents. A two-phase pre-post-intervention study was performed. The weight of toothpaste was calculated by a portable electronic compact balance. Results: A quarter of parents and <20% children dispensed the appropriate amount at baseline. Almost 85% parents and 50% children achieved the pea-sized amount after intervention. Half of the children continued to use the recommended toothpaste amount after 6 months. Children with higher intellectual functioning and conceptual skills were more likely to dispense the pea-sized amount of toothpaste. Conclusions: Visual-verbal integration model training had a desired impact on parents' toothpaste-dispensing performance. Children with higher adaptive skills may benefit from VVIM training.
