摘要
目的应用自酸蚀法和磷酸酸蚀法为低龄儿童处理牙面后行窝沟封闭术,比较窝沟封闭剂的保留率,评价自酸蚀粘接剂与全酸蚀粘接剂在低龄儿童行窝沟封闭术中应用的效果。方法选择4颗第二乳磨牙完全萌出并无龋坏的儿童67例为研究对象,268颗第二乳磨牙作为试验牙。采用自身对照的方法,分为4组,右侧A组(上颌)、B组(下颌)采用自酸蚀法,左侧C组(上颌)、D组(下颌)采用磷酸酸蚀法。术后随诊3、6、12、24个月,比较4组封闭剂的脱落率。结果 A^D四组患牙3、6个月时封闭剂保留率差异无统计学意义(P>0.05);第12个月时,A、C组均与D组的封闭剂保留率差异有统计学意义(P<0.05),但B、D组与A、B、C组之间差异无统计学意义(P>0.05);第24个月检查时,A、B、C组均与D组的封闭剂保留率差异有统计学意义(P<0.05),但是A、B、C组之间差异无统计学意义(P>0.05),下颌全酸蚀组的保留率明显低于其他三组。结论下颌牙齿更易受唾液污染,使用自酸蚀法可以减少唾液污染产生的影响,提高窝沟封闭剂的保留率,推荐临床上为低龄患儿使用。
Objective Compare the retention rate of fissure sealants when using self-etching adhesive and phosphate acid for the clean tooth surfaces of young children. To evaluate the effect of the application of pit and fissure sealant with self- etching adhesives and phosphoric acid. Methods Sixty-seven children with complete eruption and no caries of the four second primary molars were selected as the study subjects. Totally 268 teeth of the second primary molars were used as test teeth, divided into four groups with the method of self control test. The right Group A（maxillary） and B（mandibular） were treated with self-etching adhesive, and the left Group C（maxillary） and D（mandibular） with phosphate-acid etching method. All the children were followed up and the rate of shedding of the four groups was compared after 3, 6, 12 and 24 months. Results The retention rates of pit and fissure sealant in four groups（A-D） had no significant difference after 3 and 6 months（P〉0.05）. At the 12 months, there was significant difference between the A, C group and the D group（P〈0.05）, but there was no significant difference between the B, D group and the A, B, C group respectively（P〉0.05）. At the 24 months, the retention rate of pit and fissure sealant in Group D was statistically lower than in the A, B, C group（P〈0.05）, but the other three groups（A, B, C） had no significant difference in the retention rate of pit and fissure sealant（P〉0.05）. The retention rate of the mandibular group with phosphoric acid etching was significantly lower than the other three groups. Conclusion The mandibular molars are more susceptible to saliva contamination. Self-etching adhesive can reduce the influence of saliva pollution and improve retention rate of fissure sealing. It is recommended to be used for young children in clinical.
