Objective To probe the risk factors of the dental fluorosis prevalence in 12-15 age group students of the high fluorine area in Tongshan of Xuzhou.Methods Stratify sampling,random sampling and cluster sampling were used in the survey.Dental fluorosis was assessed by Dean＇s score and caries prevalance followed the World Health Organization criteria.A questionnaire was used to obtain information about some knowledge relevant to oral health.Epidata3.0 and SPSS11.5 were used for data processing.Results In a multiple logistic regression analysis,the variable female（OR = 1.569 /CI（1.091 ～ 2.254））,the severe dental fluorosis（OR = 2.758 /CI（1.401 ～5.426）） came out as the significant risk factors associated with dental caries,and the family income that was 800 ～1500 $ helped protect the dental caries（OR = 0.444 /CI（0.282 ～ 0.701））.The answer＂Two years＂for the question＂How long do you test your teeth？＂（OR = 3.75 /CI（1.425 ～ 9.869）） and the answer＂Clean the teeth＂for the question that＂what is the reason for brushing teeth？＂（OR = 1.54 /CI（1.003 ～ 2.364）） were the risk factors associated with dental caries.Conclusions Female,dental fluorosis and family income were associated with dental caries.Some answers about oral heath were associated with dental caries too.
