Efficacy of regular professional brushing by a dental nurse for 3 months in nursing home residents-A randomized, controlled clinical trial.

Objective: The oral health of nursing home residents is poor for various reasons. Many require help for oral hygiene. Regular professional brushing by a dental nurse should improve oral hygiene. This study aimed to determine the efficacy of regular tooth brushing by a dental nurse on the oral health of nursing home residents.

Methods: This controlled trial randomized participants (n = 50; mean age 83 ± 8 years) to brushing by a dental nurse every 2 weeks for 3 months (n = 25; test group) or oral hygiene procedures performed/controlled by nursing home staff (n = 25; control group). Personal, general and oral health, as well as various oral hygiene parameters-plaque index (PI), gingivitis index (GI), papilla bleeding index (PBI), oral hygiene index (OHI) and Volpe-Manhold Index (VMI)-were evaluated at baseline, after initial professional dental cleaning and before last brushing.

Results: At baseline, oral health was impaired according to investigated indices in both groups. After professional brushing for 3 months, there were improvements in PI, GI and PBI, with significant increases compared with the control group in OHI and VMI (P = 0.017 and P < 0.001, respectively). Among the control group, the number of teeth decreased while the root caries index increased (P = 0.002 between groups).

Conclusions: Regular professional brushing every 2 weeks by a dental nurse can be recommended for nursing homes residents to improve oral health parameters and to help reduce root caries incidence as a basis to preserve the number of teeth. Such oral hygiene procedures will maintain and improve the oral health of nursing home residents.
