[摘要]目的：探讨不同修复方式对乳磨牙龋病大面积缺损修复的临床应用效果。方法：选取2016年10月-2017年10月在四川锦欣妇女儿童医院口腔科就诊的乳磨牙龋病大面积缺损的患儿135例。将所有患儿随机分为三组，记为A、B、C组，每组45例。A、B、C三组分别采用光固化复合树脂充填、金属预成冠以及Hall技术修复。比较三组患牙修复后6、12、24个月的成功率。结果：三组修复后6个月及12个月临床治疗成功率比较，差异无统计学意义（P>0.05）;修复后24个月，B组的临床治疗成功率为84.44%，C组的临床治疗成功率为86.67%，均显著高于A组的73.33%，差异有统计学意义（P<0.05）。结论：与光固化复合树脂充填修复相比，金属预成冠修复与HALL技术在乳磨牙龋病大面积缺损修复中具有更好的临床应用效果，值得临床进一步推广应用。

Abstract：Objective To observe the effect of different restoration methods on large area defect of deciduous molar. Methods 135 children with large area defect of deciduous molar were selected in our hospital from October 2016 to October 2017. All patients were randomly divided into three groups， recorded as group A， group B and group C， each group had 45 cases. Group A of patients accepted light-cure composite resin filling，Group B of patients accepted metal crown restoration， and Group C of patients accepted Hall technique. The successful rate of restoration in 6， 12， and 24 months after restoration was compared between the three groups. Results There was no significant difference in the clinical treatment success rate between three groups in A，B and C at 6 and 12 months after restoration（P>0.05）.The clinical treatment success rate of group B （84.44%） and group C （86.67%） was significantly higher than that of group A （73.33%） at 24 months after restoration， and the difference was statistically significant （P<0.05）. Conclusion  Compared with the light-cure composite resin filling，the metal crown restoration technology and HAll repair technology have better clinical application effect in the large area defect of deciduous molar， which worthes further of clinical application.

齲病是临床常见的细菌感染性口腔疾病，好发于儿童并发展迅速，若未及时采取干预措施治疗极易造成儿童牙冠大面积损坏，甚至缺失[1]。儿童乳牙龋最为常见的是乳磨牙龋大面积缺损，不仅影响患儿的正常咀嚼功能，还对颌骨的正常发育造成危害[2]。随着口腔医疗技术的不断发展，乳牙龋病的修复方法日益增多，多种修复方式已得到大家认可[3]。传统的修复方法是采用复合树脂进行充填粘接修复，可有效填充龋洞，具有较好的修复效果[4]。金属预成冠修复操作简单且经济实用，可恢复正常咀嚼功能，修复效果良好并持久，在临床上被广泛应用[5-6]。HALL技术是采用预成冠隔离龋坏组织与口腔组织，其操作简单易行，无需对龋坏乳磨牙进行充填、局麻及任何牙体预备，适用于牙髓健康的患牙，可避免机械振动对患儿造成恐惧心理，提高修复舒适度[7-8]。本研……
