Oral hygiene levels and periodontal disease prevalence among residents with mental retardation at various residential settings

This pilot study compared oral hygiene levels and periodontal disease prevalence among residents with mental retardation in a large traditional state institution, a small regional facility, and community group homes. Plaque scores and periodontal disease levels were high in all groups. However, there was a significant difference (P less than 0.05) among the group home residents, who had lower scores, than the other groups. These results indicate that preventive dental programs are necessary in new residential settings for individuals with mental retardation.
