Methods: a total of 310 children with eruption of mandibular first molars who underwent routine physical examination in kindergartens in this city from August 2018 to October 2019 were randomly selected as research objects. They were randomly divided into the control group and the study group with 155 children in each group receiving different oral care measures, and the situation in the next 24 months was tracked and studied. The children in the control group were given routine oral care such as brushing their teeth in the morning and evening and gargling after meals, while the children in the study group were given oral care based on this. The occurrence of caries of the first permanent molars in the two groups at 6, 12, 18 and 24 months after physical examination and the preventive effect of the two kinds of care measures were observed and compared. Results: after 6 months of nursing, there was no significant difference in the incidence of caries between the two groups (1.83%vs2.17%) (P > 0.05). In the last three stages, the incidence of dental caries in children showed an upward trend. The incidence rates in the study group were 6.33%, 9.67% and 13.17% respectively, and the incidence rates in the control group were 14.33%, 19.50% and 24.83%, respectively. Compared with the control group, the incidence rates of dental caries in the study group were lower than those in the control group at each stage (p < 0.05). In addition, 6 months after nursing, there was no significant difference between the two groups (P > 0.05). In the last three stages, the average caries and caries surface of the two groups increased gradually, but the average caries and caries surface of the study group were lower at each stage (P < 0.05). Conclusion: fluorine protective paint has good preventive effect on children's first permanent molar caries, and the incidence of dental caries is low within two years, which is worthy of wide promotion.展开更多
