The purpose of the present survey is to ascertain basic data on oral malodor at the community level and the relationship between oral malodor and oral health status. 2672 people aged 18 to 64 years who lived in Fukuoka Prefecture were measured for oral malodor using a portable sulfide monitor, assessed for their oral health status and interviewed about their life style. The subjects were divided into four examination groups : those examined in the morning within 2 hours from final oral activities, beyond 2 hours from final oral activities, and those examined in the afternoon also within 2 hours from final oral activities or beyond. Significant differences in volatile sulfur compounds (VSC) were not observed between males and females in every measurement group. For each age group both in the morning and in the afternoon, the VSC value was significantly higher in a time period beyond 2 hours from their final oral activities, such as eating, drinking tea, tooth brushing, than in a period within 2 hours from such activities. The VSC obtained from older age groups was significantly higher than that from younger age groups in both time periods in the afternoon. However, the VSC values were not significant between age groups in the morning. Correlation analysis demonstrated an association between oral malodor and tongue coating or periodontal conditions. However, no association was found between the VSC and the number of decayed teeth, quantity of plaque, frequency of tooth brushing or smoking habits. The percentages of persons having 75 ppb and over of the VSC, which was considered a socially acceptable level of oral malodor, ranged from 6% to 23%. The result suggests that at any time of the day 6% of a population have oral malodor and 17% have it part time depending on their health condition. These findings will provide basic information on oral malodor for planning and implementation of an oral health programme for the general population.
