Volatile sulphur compound measurements, organoleptic measurements, and tongue coating were selected as outcome variables, and independent screenings were conducted with 333 unique titles and paper abstracts. Twelve publications (12 experiments) met eligibility criteria for this review.
The review concluded that nearly all mouthwashes with active ingredients had beneficial effects in reducing oral malodor in both short- and longer-term studies. “The most compelling evidence was provided for chlorhexidine mouthwashes, and those that contained a combination of cetyl pyridinium chloride and zinc provided the best evidence profile on oral malodor. Little data with respect to tongue coating were available, and none of the studies showed a beneficial effect for this parameter,” the study says.
