The purpose of this study was to investigate betel-quid chewing behavior and its effect on the oral health and the morbidity rate ot precancerous oral lesions (erythroplakia, leukoplakia and submucous fibrosis). Oral health behavior, alcohol consumption, cigarette smoking, sex and social factors were also studies. An oral health examination and questionnaire, which surveyed 85 residents (male=35, female=50) of Manchou country, found that 66 of them were betel-quid chewers (74.12 % of the testers). Ofthose 66 betel-quid chewers, 18 (male=9, female=9) developed precancerous oral lesions. The data were analyzed by the Chisquare test. Comparing the difference between the precancerous Drallesions patients and healthy residents, oral health behavior (teeth brushing frequency, dental floss use, ordinary teeth check etc.) was not significant. In both male and female subjects, the morbidity rate of precancerous oral lesions was significantly associated with betelquid chewing, cigarettes smoking and alcohol consumption (p=0.0290). The study proved betel-quid chewing is detrimental to oral health. To improve oral health in Manchou country, it is suggested that betel-quid consumption should be reduced or eliminated. Especially the residents who also smoke cigarettes and consume alcOhol, as these residents are the most at risk, they need to be dissuaded.
