Abstract

Abstract:

Objective To analyze pit and fissure sealing spatial heterogeneity and related influencing factors in Shanxi Province. Methods In 2016, 937 children aged 7 to 9 years were randomly selected from primary schools for pit and fissure sealing, and the effect of pit and fissure sealing was evaluated in 2017,2018 and 2021. The q-statistic was used to analyze the spatial heterogeneity of retention rate and influencing factors. Results The GeoDetector model was used to study the influence of eight influencing factors, including socioeconomic, medical resources and natural environment, one year,two and five years after pit and fissure sealing. Five years after pit and fissure sealing, the degree of spatial stratification and heterogeneity of the postoperative sealant retention rate was the largest, and the trend of increasing from north to south was the most obvious. The highest q value was observed at 1 year after surgery (q=0.52, P<0.05), indicating that water fluoride content was an important environmental factor determining the spatial heterogeneity of sealer retention at 1 year after surgery, followed by mean annual precipitation. The highest q values were observed for the proportion of health technicians at 2 and 5 years after surgery (q=0.70,P<0.05; q=0.69, P<0.05), indicating that the proportion of health technicians was an important environmental factor determining the spatial heterogeneity of sealant retention rates at 2 and 5 years after surgery. Conclusion In Shanxi Province, the total retention rate of sealant after one year was 95.06%, two years, 89.30%, and five years, 64.55%. There is spatial heterogeneity in the retention rate after fissure sealing, which increases from north to south. The proportion of health technicians and water fluoride content are the main factors influencing the spatial heterogeneity of fissure closure retention rate.

Key words: pit and fissure sealing, sixth-year molar, oral disease prevention, spatial heterogeneity
