Clinical and antimicrobial evaluation of a mouthwash and toothpaste for xerostomia: a randomized, double-blind, crossover study.

OBJECTIVES

Specific toothpaste and mouthwash for xerostomia based on triclosan, fluoride, and mineral salts were studied in order to evaluate their efficacy in improving the quality of life as well as their in vitro antimicrobial action.

MATERIALS AND METHODS

30 patients with dry mouth and hyposalivation confirmed by sialometry were included in a randomized, double-blind, crossover study, during two weeks for each experimental phase. Dryness and oral comfort, difficulty in speaking, chewing, swallowing and using dental prostheses, as well as taste and sleep disorders were evaluated. Values of minimal biocidal and minimal inhibitory concentrations of both products against microorganisms that often cause oral disorders in these patients were determined and compared.

RESULTS

The use of the mouthwash and toothpaste studied improved the dry mouth symptoms, whilst no significant differences when compared with the salivary enzyme substitutes were observed. The test products showed, in general, a higher biocidal and inhibitory action than the control products, with particularly noteworthy action against cariogenic bacteria.

CONCLUSIONS

The use of a toothpaste and mouthwash based on triclosan, fluoride, gingival revitalizers and mineral salts, improves the quality of life of patients suffering xerostomia.
