两种窝沟封闭术防龋效果的临床观察

摘要

目的：研究两种窝沟封闭术预防龋病的临床疗效。方法：选择在我院儿童牙病科门诊就诊的160例6～8岁儿童，采用自身双侧对照，分别以窝沟釉质成形封闭术(enameloplasty sealant technique，EST)和普通窝沟封闭术(conyentional sealant technique ，CST)封闭下颌第一恒磨牙320颗，观察两种窝沟封闭术的保留率和龋病发生率。结果：随访3年后，实验组窝沟封闭剂的保留率明显高于对照组，且患龋率明显低于对照组(P均<0.05)。结论：EST较CST有明显提高窝沟封闭效果，且龋病发生率明显降低。%Objective:To study the application of two kinds of socket channel closed for preventing caries disease of clinical curative effect. Methods:By choosing patients from our children’s dental clinics, 160 cases of children aged between 6 and 8 years, using its own bilateral control, respectively by enameloplasty sealant technique (EST) and conyentional sealant tech-nique (CST) closed mandibular first permanent molar 320, observe two nest mouth retention rate and the incidence of tooth decay. Results: Followed up for 3 years, observe two groups of nest mouth retention rate and the incidence of tooth decay. Retention rate of socket channel blocking agent was obviously higher than that of controls , and risk of caries rate is signifi-cantly lower than the control group(P<0.05). Conclusion: Compared with CST, EST can obviously improve nest ditch seal-ing effect, and significantly decrease incidence of tooth decay.
