In order to evaluate the effectiveness of tooth brushing, mouth gargling and gum chewing in reducing halitosis. 84 individuals ranging in from 22 to 28 years old were examined. These individuals had no gross oral abnormalities, other than mild
gingival
inflammation, dental caries, nasopharyngeal disorder, or systemic diseases that were associated with halitosis. They were divided into a tooth brushing group, a mouth gargling group, a gum chewing group and a control group that did not use any
halitosis
removing method. Each of the groups included 21 persons. B.B. Checker (Tokuyama Soda Co., LTD., Japan) was used to measure the concentrations of intraoral volatile methyl of each group. The concentrations of intraoral volatile methyl mercaptan
were
measured before and after lunch, and after removing halitosis by tooth brushing mouth gargling and gum chewing.
@ES The obtained results were as follows:
@EN 1. The average concentration of intraoral volatile methyl mercaptan before lunch was 1.79ppm and after lunch it was 2.02ppm, and incerase of 12.9%.
2. In the tooth brushing group the average consentration of intraoral volatile methyl mercaptan was 0.61ppm, in the mouth gargling group it was 1.15ppm, in the gum chewing group it was 1.64ppm and in the control group it was 1.92ppm, It
decreased
69.5%
in the tooth brushing group, 43.8% in the mouth gargling group, 18.4% in the gum chewing group and 5.4% in the control group(P<0.05).
3. There were significant differences between the tooth brushing and control group, tooth brushing and gum chewing group and between mouth gargling and control group in concentrations of intraoral volatile methyl mercaptan after using the
halitosis
removing methods (P<0.05).
According to the above results, tooth brushing and mouth gargling are effective ways to reduce halitosis.
