Objective: The purpose of this study was to identify the changing trend by hour of the oral malodor of ordinary people.
Materials and Methods: We measured the oral malodor by using Oral Chroma which is a based on volatile sulfide compound and BB Checker which is a device that measures overall gas inside the mouth. To identify the trend, the research selected 20 applicants, of which 10 applicants were teens while the other 10 were in their 30’s. The applicants’s breath was measured in every 2 yours from 7:00 in the morning and they were measured 8 times in total.
Results: The oral malodor is not influenced by age or gender (p＞0.05). The highest possibility to have oral malodor during the day is right after applicants wake up in the morning (p＜0.05). The oral malodor is reduced after meal as it is compared to before meal. The oral malodor increases as the time goes by.
Conclusion: The level of oral malodor changes during the day as time goes by. In this regard, it is recommended that when the change of oral malodor is identified, the breath of participants be measured at the same time of the day in order to eliminate the time factor.
