title: Reduced formation of supragingival calculus with use of fluoride-zinc chloride dentifrice.
abstract: Results of this comparative, double-blind, clinical study show that fluoride dentifrice with 2.0% zinc chloride is effective in reducing calculus accumulation after a dental prophylaxis. The data also confirm earlier observations on calculus formation in that accumulation was not constant during the two 3-month study phases.
