[Daily living activities and oral condition among care facility residents with severe intellectual disabilities. Comparative analyses between residents receiving tooth-brushing assistance and those not receiving tooth-brushing assistance].
OBJECTIVE
To clarify 1) differences in daily living activities and oral condition among care facility residents with severe intellectual disabilities and 2) chronological changes in daily living activities and oral condition for residents receiving tooth-brushing assistance and those never receiving tooth-brushing assistance.


METHODS
Subjects were 44 residents at a care facility for individuals with severe intellectual disabilities, who underwent dental screening in July 1994 and October 2003. At each time point, daily living activities, behavior during oral health guidance, behavior during dental health screening and oral condition were compared between residents receiving tooth-brushing assistance (assistance group) and those not receiving tooth-brushing assistance (independent group). Furthermore, chronological changes were analyzed for residents requiring assistance at both screenings, those requiring assistance only at the second screening, and those not requiring assistance at either screening.


RESULTS
1) In the assistance group, 100% and 36.4% of residents were unable to brush their teeth independently in 1994 and 2003, respectively. Significant differences between the assistance and independent groups were observed in all items of behavior during dental health screening in 1994, but not in 2003. No significant intergroup differences in oral condition were observed in 1994, but differences were seen in 2003; when compared to the assistance group, the number of lost teeth was significantly higher in the independent group, while the number of remaining teeth was lower. 2) Regarding changes over the nine-year period, a significantly greater proportion of residents not requiring assistance at either screening and those requiring assistance only at the second screening finally required assistance in bathing. As for oral condition, no significant changes in healthy teeth were observed in residents requiring assistance at both screening time points, while significant increases in dental caries and filled teeth and a significant decrease in the number of healthy teeth were observed in residents requiring assistance only at the second screening and those not requiring assistance at either screening.


CONCLUSIONS
Over the nine-year period, the subjects of tooth-brushing assistance changed, and assistance was given to those able to brush their teeth independently in addition to those unable to brush their teeth independently. The number of healthy teeth did not change in residents receiving tooth-brushing assistance during this period, but in residents never receiving tooth-brushing assistance, decrease was noted. Therefore, even for individuals able to brush their teeth independently, some form of tooth-brushing assistance is needed to sufficiently prevent oral diseases.
