Abstract
Objective: This study was conducted to confirm the oral malodor reduction effect of zinc citrate-containing dentifrice on night use.Methods: This study was designed as a parallel, randomized, double-blind, and control trial for 3 weeks. After 1-week run-in period, the subjects were randomly assigned to the experimental groups (zinc-citrate-containing-dentifrice using group) or the control group. After 3 days, 5 days, 1 week, 2 weeks, and 3 weeks, oral malodors were measured and compared.Results: As a result of measurement of volatile sulfur compounds using Oralchroma, before the experiment, the experimental group 3.01 ng/10 ml and the control group 3.03 ng/10 ml, after 3 days, 2.77 ng/10 ml, 3.01 ng/10 ml, after 5 days, 2.67 ng/10 ml, 2.95 ng/10 ml, after one week, 2.62 ng/10 ml, 2.96 ng/10 ml, and decreased to 2.50 ng/10 ml and 2.92 ng/10 ml after 2 weeks.Conclusion: In case of using the dentifrice for the oral malodor using zinc citrate once before sleeping, It was confirmed that the effective and quick oral malodor reduction effect can be expected compared with the existing dentifrice.
