【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(P0.05);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(P0.05),但B、D组与A、B、C组之间差异无统计学意义(P0.05);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(P0.05),但是A、B、C组之间差异无统计学意义(P0.05),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。
[Abstract]:Objective to evaluate the effect of self-etching and total acid etching in the treatment of low age children by the method of self-etching and phosphoric acid etching, and to compare the retention rate of sealant and self-etching adhesive in the treatment of young children. Methods Sixty-seven children with complete eruption of the second primary molars and no caries were selected as subjects. 268 second molars were selected as experimental teeth. The patients were divided into 4 groups by autocontrol, right group A (mandible) and left group C (group D) were treated with phosphate acid etching. 6 cases were followed up for 12 months and 24 months after operation. The rate of sealant loss was compared in 4 groups. Results there was no significant difference in the retention rate of sealant between group A and D at 3 and 6 months, but there was no significant difference between group A and group D at the 12th month. At the 24th month, there was a significant difference in the retention rate of the sealant between group C and group D, but there was no significant difference between the two groups. The retention rate of total mandibular acid etching group was significantly lower than that of the other three groups. Conclusion the mandibular teeth are more susceptible to saliva contamination. Self-etching can reduce the influence of saliva contamination and increase the retention rate of sealant. It is recommended that this method should be used clinically for young children.
