自酸蚀粘结剂并窝沟釉质成形窝沟封闭效果的临床观察

Clinical Effect of Pit and Fissure Sealant Used in Combination with Self-etching Adhesive and Enameloplasty Sealant Technique

目的:观察使用自酸蚀粘接剂并窝沟釉质成形方法对正畸磨牙窝沟封闭的临床效果。方法:选择54例9～16岁正畸患者,共154颗健康下颌第一或第二恒磨牙,分为2组,分别采用自酸蚀粘结剂并用窝沟釉质成形和自酸蚀粘结剂处理的方法行窝沟封闭,比较两种牙面窝沟处理方法封闭剂的保留率和龋病发生率,并通过自身对照,观察其临床效果,应用SPSS13.0统计软件包对数据进行卡方检验。结果:12个月时自酸蚀粘结剂并窝沟釉质成形处理方法窝沟封闭剂的完整保留率为87%,单独使用自酸蚀粘结剂窝沟封闭剂的完整保留率为69%;12个月时实验组发现2颗龋齿,对照组发现4颗龋齿,实验组龋降低率为50%;实验组窝沟封闭的的操作时间为(150±12)s。结论:应用自酸蚀粘接剂操作简单,技术敏感性低,结合使用窝沟釉质成形后封闭剂的完整保留率与磷酸酸蚀窝沟封闭剂的完整保留率接近,可替代磷酸在窝沟封闭时应用。

Objective： To observe the clinical effect of pit and fissure sealant used in combination with self- etching ad- hesive and enameloplasty sealant technique（EST） on molar following orthodontic treatment. Methods： 154 health mandi- ble the first or second molar in 54 orthdontie treatment patients aged from 9 to 16 years were divided into two groups . The teeth in one side used serf - etching adhesive and EST while the teeth in other side used serf - etching adhesive , and sealed with sealant（ ConeiseTM ,3M- ESPE）. The rate of the sealant reservation and the caries decreased were eompared in two groups, and used SPSS 13.0 software package for Chi -square test. Results： The full retention rates in serf- etching ad- hesive with EST and in self - etching adhesive were 87% and 69% respectively after treatment. There were 2 caries in pa- tients using self - etching adhesive and EST, while 4 caries in patients using self - etching adhesive. The caries decreased rate was 50%. The operating time using self - etching adhesive and EST was （ 150 ± 12 ） s, not much longer than only u- sing self - etching adhesive. Conclusion： Self - etching adhesive may use to replace the phosphate acids in pit and fissure sealant.
