Objective To have knowledge about the oral health condition of college students so as to provide a scientific basis for oral health care of college students.Method The prevalence of dental caries

oral health self-care knowledge and prevention and curing condition of 554 non-oral medicine college students of our university were surveyed by means of self-designed questionnaire and oral examination.Results The detection rate of dental caries was 46.39% and the filling rate of dental caries was 35.19%.The detection rate of dental caries for urban students was higher than that for rural students（χ2=5.361

p<0.05） and the detection rate of dental caries for the females was higher than that for the males（χ2=10.852

p<0.05）;differences in the dental caries detection rate of students from different grades were statistically significant（χ2=16.420

p<0.05）.The filling rate of dental caries for urban students was higher than that for rural students（χ2=9.493

p<0.05）;the higher the grade

the higher the filling rate

and differences in the dental caries filling rate of students from different grades were statistically significant（χ2=9.655

p<0.05）;Conclusion College students know little about the oral hygiene and health care.The oral health condition and the oral hygiene habit of higher-grade students are better than those of lower-grade students.
