Objective : This study was performed in order to provide basic data for halitosis prevention and
establish a device to efficiently eliminate halitosis and to analyze the factors that affect the halitosis.
Methods: Oral examination on the Gingival index, CPITN, Tongue Plaque index, and OHI-S as well
as halitosis measurement among 293 rural residents.
Results : Gingival index was high at mild on female and at moderate on male(p=0.025). Sorting the
result by age, mild was 54.1% in the 40s, and moderate was 49.5%, 42.0% and 70.0% each in the 50s,
60s, and the 70s(p=0.005). The need for dental plaque management was 100%. The need for scaling
was high with 78.3%, 93.0%, 89.9%, and 90.0% each for the 40s, 50s, 60s, and 70s. The need for complex
periodontal treatment was also high with 32.4%, 47.5%, 48.7% and 60.0%, each for the 40s, 50s,
60s, and 70s(p=0.050). The highest bad condition for OHI-S was 69.5%, and good being 18.9%, and
very bad being 11.6%. For moderate tongue plaque index was 74.4% as the highest. As the level of
education increased, the slight tongue plague was increased, but in contrast, the moderate and higher
tongue plague index was decreased(p=0.010). OG under 50ppm was 61.1% on male and OG over
50ppm was 50.9% on female(p=0.041). In OG over 50ppm, CPITN was 52.1% and 41.9% in scaling
and complex periodontal treatment group(p=0.018). OHI-S, in bad and very bad condition with OG,
over 50ppm, was 48.7% and 46.9%(p=0.019). The higher tongue plague index showed significant
amount of increase at OG and EG above 50ppm(p=0.006). NH3, as the tongue plaque index
increased, the wider range of distribution was shown(p=0.000). As for the multiple regression analysis result, there have been selected females and tongue plaque index as factors affecting OG. There
have been selected age and tongue plaque index as factors affecting EG and there have been selected
females as factors affecting on NH₃.
Conclusions : With the aforementioned results in mind, the status of halitosis among rural residents
is considered to bare a close relation with oral environments. we have to focus on correct tooth
brushing methods and tongue brushing, with using tongue cleaner to remove fur of tongue plaque.
Also, in order to analyze exactly the factors of individual halitosis, we need continuous and systematic
