Objective: The aim of this study is to investigae the effect of Zinc citrate containing dentifrice for oral malodor control.
Methods: The experimental dentrifice containing zinc citrate, the comparison dentrifice, and the control dentrifice prepared from the removal of major constituents of the experimental dentrifice were applied to the experimental group (n=30), the comparison group (n=30), and the controlled group (n=30). Thus, a total of 90 volunteers were instructed to use the corre-sponding dentrifice for 4 weeks. Calculus index, papillary marginal attachment gingivitis index, gingival index, patient hy-giene performance index, and plaque index were measured at a total of 4 sessions, i.e., prior to the experiment, at week 1, at week 2, and at week 4. The degree of mouth odor was recorded with the Oralchroma and B&B checker.
Results: Pre-experimental measurements of volatile sulfur compounds using Oralchroma were 2.40 ng/10 ml in the ex-perimental group, 2.48 ng/10 ml in the comparison group, and 2.22 ng/10 ml in the controlled group. At 4 weeks, these val-ues were decreased to 1.09 ng/10 ml, 1.79 ng/10 ml, and 1.86 ng/10 ml, respectively. The mouth odor was significantly re-duced in the experimental group. Pre-experimental mouth odor measures using the B&B checker were 70.2 BBV in the ex-perimental group, 70.9 BBV in the comparison group, and 72.5 BBV in the controlled group. At 4 weeks, these values were decreased to 49.5 BBV, 59.9 BBV, and 62.9 BBV, respectively. The experimental group showed a significant reduction in mouth odor after week 2.
Conclusion: These results indicated that a zinc citrate containing dentrifice was more effective and prompt, as compared with a conventional type of dentrifice for mouth odor.
