摘　　要：目的 探索山西省第一恒磨牙窝沟封闭保留率的空间异质性及相关影响因素。方法 2016年从小学随机抽取937名7至9岁的儿童行窝沟封闭术,在2017年、2018年和2021年分别进行窝沟封闭术后效果评估,应用q-统计量分析窝沟封闭保留率与影响因素的空间异质性。结果 应用GeoDetector模型研究了窝沟封闭术后1、2和5年社会经济、医疗资源、自然环境3方面8个影响因素对窝沟封闭保留率的影响,术后5年封闭剂保留率的空间分层异质性程度最大,由北向南呈现增加的趋势最为明显;术后1年水氟含量的q值最高(q=0.52,P<0.05),表明水氟含量是决定术后1年封闭剂保留率空间异质性的重要环境因素,其次是年平均降水量。术后2年和5年卫生技术人员比例的q值最高(q=0.70,P<0.05;q=0.69,P<0.05),表明卫生技术人员比例是决定术后2年和5年封闭剂保留率空间异质性的重要环境因素。结论 在山西省,窝沟封闭术后1年封闭剂总保留率为95.06%,术后2年封闭剂总保留率为89.30%,术后5年封闭剂总保留率为64.55%;窝沟封闭术后的保留率存在空间异质性,表现为从北到南增加;卫生技术人员比例与水氟含量为窝沟封闭保留率空间异质性的主要的影响因素。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.
