目的比较非创伤性修复治疗(ART)和常规玻璃离子充填方法治疗儿童第一恒磨牙龋的充填体保留情况。方法 82名患儿,浅龋、中龋共104颗,配对分为两组:ART组52颗,手用器械去腐,Ketac molar充填;对照组52颗,机钻去腐,Fu ji II LC充填。随诊6个月、12个月,评价两组充填体保留情况。结果 6个月后复查ART组48颗,对照组51颗,充填体存留率分别为93.75%和96.08%,经统计学检验差异无统计学意义(P>0.05)。12月后复查ART组41颗,对照组46颗,充填体存留率分别为85.37%和86.96%,差异无统计学意义(P>0.05)。12个月时ART组和对照组的累计生存率分别为80.03%和83.55%,差异亦无统计学意义(P>0.05)。结论 6个月、12个月后ART组和对照组的充填体存留率和累计生存率相似,ART和常规玻璃离子充填的效果相似,ART可用作儿童恒磨牙龋的治疗。
Objective To compare the retention of non-invasive repair (ART) and conventional glass iontophoresis in the treatment of children’s first permanent molar caries. Methods A total of 104 children with superficial caries and dental caries were divided into two groups: ART group (n = 52), hand instrument decontamination and Ketac molar filling; control group (n = 52) Filling. Follow-up 6 months, 12 months, evaluation of two sets of filling retention. Results Six months later, 48 ART patients and 51 control patients were examined. The retention rates of the infiltrated materials were 93.75% and 96.08%, respectively. There was no significant difference between the two groups (P> 0.05). After December, 41 ART patients and 46 control patients were reexamined. The retention rates of filling bodies were 85.37% and 86.96% respectively, with no significant difference (P> 0.05). The cumulative survival rates of ART group and control group at 12 months were 80.03% and 83.55% respectively, with no significant difference (P> 0.05). Conclusion After 6 months and 12 months, the retention rate and cumulative survival rate of ART group and control group are similar. ART is similar to conventional glass ion implantation. ART can be used as a treatment for permanent molar caries in children.
