Objective To evaluate the effect of the comprehensive intervention of the oral health education for children aged 6 to 12 years.Methods The oral health knowledge questionnaire was used to evaluatethe children′s awareness about oral health and the correct rate of tooth-brushing before and after 12-month comprehensive intervention. Two organizational forms about pit and fissure sealant were adopted. In city school, students were brought by their parents to the hospital to do pit and fissure sealant, while in rural school, hospital medical team went to schools to do pit and fissure sealant for the students. Compare the sealants retention rate in 12-month follow-up between two forms. The total sealants retention rate among 6-month, 12-month and 24-month follow-up were compared.Results Before and after oral health education guidance, the rate of children′s oral health awareness was 68% and 96%, and the correct rate of tooth-brushing was 64% and 92% respectively (P<0.05). There was statistical difference before and after comprehensive intervention. The rate of pit and fissure sealant was 84.02% in city school and 97.98% in rural school and the sealant retention rate in 12-month follow-up was 86.75% and 85.29% respectively(P<0.05). The total sealants retention rate among 6-month, 12-month and 24-month follow-up were 92.01%, 86.02%, and 82.14% respectively (P<0.05).Conclusion The oral comprehensive intervention is helpful to improve the children′s awareness about oral health.
