Abstract

Objectives
This study aims to verify the effect of the use of a toothpaste containing 0.5% zinc citrate and 1,450 ppm fluoride on oral malodor.
Methods
In this study, the experimental group using the experimental toothpaste and the control group using the standard toothpaste control toothpaste were allowed to use each toothpaste for 4 weeks and then a clinical test to measure the change in bad breath was conducted. A study was conducted to evaluate the reduction effect. Efficacy was evaluated by conducting BB checker test and Oralchroma test three times in total before the testing 2 weeks and 4 weeks after the test.
Results
As a result of measuring the degree of bad breath using the BB checker, before the start of the test, the experimental group was 46.3 and the control group was 47.2. After 2 weeks of the test, the experimental group was 38.5 and the control group was 44.2 and after 4 weeks the experimental group was 29.6 and the control group was 39.2. There was a significant difference between the experimental group and the control group after 4 weeks of the test (P<0.05). The volatile sulfur compounds measured by Oralchroma were 0.825 ng/10 ml for the experimental group and 0.819 ng/10 ml for the control group after 2 weeks of the test, and they were 0.705 ng/10 ml for the experimental group and 0.860 ng/10ml for the control group after 4 weeks of the test. It was confirmed that a significant index change appeared after 4 weeks of the test compared to before the test (P<0.05).
Conclusions
It was confirmed that an improved effect of removing bad breath can be expected when a toothpaste containing 0.5% zinc citrate and 1,450 ppm fluoride is used.
