Preventive effect of cavity and fissure sealing and resin filling on deciduous teeth caries
窝沟封闭术与预防性树脂充填术对乳牙龋病的预防作用研究

摘要

目的 探究窝沟封闭术与预防性树脂充填术对乳牙龋病的预防作用。方法 选择本院2021年8月-2022年3月期间临床收诊乳牙龋病患儿作为研究主体，共计100名纳入统计。根据随机分组法分为常规组、实验组，每组50名。常规组予以窝沟封闭术治疗、实验组予以窝沟封闭术与预防性树脂充填术治疗，比较两组不同时间密封剂保存率、龋齿发病率、龋均值水平和牙齿健康指标、预防治疗满意度。结果 干预后6个月两组密封剂保存率、龋齿发病率、龋均值水平无差异，P＞0.05。干预后12个月、18个月相较常规组，实验组密封剂保存率更高，龋齿发病率、龋均值水平更低，P＜0.05。相较常规组，实验组牙齿健康指标更优、预防治疗满意度更高，P＜0.05。结论 窝沟封闭术与预防性树脂充填术治疗可对乳牙龋病起到预防作用，提高牙齿功能，建议普及使用。

Abstract

Objective To investigate the preventive effect of cavity and fissure sealing and resin filling on deciduous teeth caries.
Methods A total of 100 children with deciduous tooth caries were selected as the subjects of the study. According to the random grouping method, they were divided into conventional group and experimental group, with 50 students in each group. The conventional group was treated with pit and fissure sealing, and the experimental group was treated with pit and fissure sealing and preventive resin filling. The retention rate of sealant, the incidence rate of dental caries, the mean level of dental caries, the dental health index and the satisfaction degree of preventive treatment were compared between the two groups at different time.
Results There was no difference in sealant retention rate, caries incidence rate and mean caries level between the two groups 6 months after intervention (P > 0.05). At 12 and 18 months after intervention, the sealant retention rate in the experimental group was higher than that in the conventional group, and the incidence of dental caries and the mean level of dental caries were lower, P < 0.05. Compared with the conventional group, the experimental group had better dental health indicators and higher satisfaction with preventive treatment (P < 0.05).
Conclusion   Pit and fissure sealing and prophylactic resin filling can prevent deciduous caries and improve dental function.
