Oral malodor prevention effect of toothpaste containing 0.5% zinc citrate and 1,450 ppm fluoride

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.
