Purpose:
To elucidate school age students' oral health status in Lishui city and monitor caries tendency of their first molars.
Methods:
Four hundred and forty-eight primary school students of the first and second grades were cluster sampled from the urban and suburb districts. The first molar crown caries were measured and their oral health caring measures were investigated.
Results:
The results showed that suburb children's DMFT and first molar caries prevalence were both higher than the children in the urban district, but the time of tooth brushing was obviously lower. The results also showed the most important influencing factors of caries were tooth brushing, followed by age, districts, and gender etc.
Conclusion:
It is suggested that we should enforce the oral health care education and promotion, especially in the suburb area.
