The purpose of this study is to work out plans to reduce oral malodor by carrying out effective methods. In the research, 17 volunteers were selected from the students at Sahmyook Health University's Dental Hygiene Dept. in order to measure the effects of reduction of oral malodor. The results are as follows. 1. As time passes, both the control group and the experimental group proved the effects of the reduction of oral malodor for 20 minutes after the experiment(p<0.05). 2. The experimental group with tooth-brushing showed a statistically significant difference compared with the control group from a lapse of 5 minutes after the experiment to 20 minutes(p<0.05). 3. The experimental group with tongue cleaner did not prove a statistically significant difference compared with the experimental group with toothbrushing( p>0.05). 4. The experimental group in which participants took a candy showed a statistically significant difference compared with the control group after 5 minutes(p<0.05). 5. The experimental group with chewing a gum proved a statistically significant difference compared with the control group for 10 minutes(p<0.05). Using a washing implement of the tongue, taking a candy, and chewing a gum proved the same effect of reducing foul breath as in the case of operating a tooth-brushing. This experiment proves that taking a candy or extending time of chewing a gum was effective in a short time, and using a tongue cleaner or chewing a gum for 5 minutes was a useful method for reducing oral malodor if not operating a tooth-brushing.
