2种酸蚀方法在窝沟釉质成形封闭术中的临床应用观察

Clinical application of two etching adhesivein enameloplasty sealant technique

目的比较磷酸酸蚀和自酸蚀应用于釉质成形术预防窝沟龋的临床疗效。方法根据适应证选择100例8岁小学生400颗第一恒磨牙,采用自身半口对照方法,窝沟釉质成形术后左侧(试验组)自酸蚀后涂布封闭剂,右侧(对照组)磷酸酸蚀后涂布封闭剂。术后跟踪随访6、12和24个月观察封闭剂保留率。结果 2组6、12和24个月封闭剂保留率相近,差异无统计学意义(P>0.05)。结论两种酸蚀方法用于窝沟釉质成形封闭术均能取得满意效果。

Objective Through a 2-year follow-up study on the effect of the two enameloplasty sealant techniques,to compare the efficacy of the application of phosphate etching and self-etching on preventing the caries of pit and fissure.Methods With split-mouth comparison,100 children aged 8 were selected to study,which means 400 first permanent molars were involved.After the enameloplasty,the left teeth of the mouth were self-etched （experimental group）,and the right ones were phosphate etched （control group）.The retention rates of sealing agent at 6 months,12 months and 24 months were followed up.Results There were no significant differences between the phosphate etching and self-etching adhesive in the retention rate of sealing agent at 6 months,12 months and 24 months （P〉0.05）.Conclusions The effect of the two etching adhesives in enameloplasty sealant technique is satisfying.
