Effects of mucosal care on oral pathogens in professional oral hygiene to the elderly.

To elucidate the effects of mucosal care on colonization of mutans streptococci and infection of Candida species, we randomized 50 functionally dependent nursing home residents, mean age 76.1 (±7.8 years), 76% females, to receive oral professional care with or without mucosal care. During 12 months of follow-up, significant reduction in the numbers of mutans streptococci in saliva and dental plaque samples were observed in both treatment groups. However, there was no reduction in the numbers of mutans streptococci in tongue samples in the non-mucosal group (p=0.150). In the comparison between the treatment with and without mucosal care, the treatment with mucosal care showed a significant inhibition effects on numbers of nutans streptococci on the tongue surface at 6 months after the treatment as compared with the treatment without mucosal care (p=0.043). Mucosal care was not associated with any significant reduction in the rate of opportunistic infection with Candida species in any of the three sites. However, more subjects without mucosal care had Candida infection in dental plaque during the follow-up (p=0.046). Professional dental care with (versus without) mucosal care had no effect on mutans streptococci colonization in saliva or plaque. Lack of mucosal care seemed to be associated with higher rates opportunistic infections with Candida species.
