The subjects of this study were slected from 7th to 9th graders by stratified cluster sampling method. From each grade, four classes were chosen and the data were collected through structured questionnaires. Total vaild samples were 391. The results of this research is shown as follows: 1. Most of the participants have had the experiences of dental caries (82.1%). But the majority of the participants do not have dental caries (80.8%) currently for they’ve just had their permanent teeth. 2. The participants’ perception of “perceived susceptibitlity of dental caries” , “perceived benefits of after-meal-tooth-cleaning behavior” and “perceived severity of dental caries” tend to be above the average; and “perceived barriers of after-meal-tooth-cleaning behavior” tends to be below the average. 3. Among the questions of the behavioral clues of after-meal-teeth-cleaning behavior, “I went to the dentist for the tooth problems” is the highest (88.5%); the question “classmates’ reminding” is the lowest (5.1%). Besides, in respect of parental reminding, mother’s reminding was more frequent than father’s. 4. The participants’ degree of “self-efficacy of after-meal-teeth-cleaning behavior” and “after-meal-teeth-cleaning behavior intention” tends to be below the average. 5. Regarding the gender of the participants, girl’s cognition of perceived susceptibility of dental caries is higher than boy’s. The cognition of perceived susceptibility of students with dental caries experiences is higher than those without dental caries experiences. The cognition of perceived barriers of after-meal-tooth-cleaning behavior of students with dental caries experiences is higher than those without dental caries experiences. 6. Gender, past experience of dental caries, perceived susceptibility of dental caries, perceived benefits of after-meal-tooth-cleaning behavior, perceived barriers of after-meal-tooth-cleaning behavior, cues to action of after-meal-tooth-cleaning behavior and self-efficacy of after-meal-teeth-cleaning behavior, and the intention of after-meal-tooth-cleaning behavior explain 29.3% of participants’ decision to preventive after-meal-tooth-cleaning behavior.餐後潔牙行為健康信念模式自我效能國中學生after-meal-tooth-cleaning behaviorHealth Belief ModelSelf-effecacyjunior high school students
