摘要:
[摘要]目的：探究金属预成冠(Preformed metal crown, PMC)对乳磨牙大面积龋病儿童活髓保存后的修复效果。方法：选取
笔者医院2017年1月-2018年1月收治的乳磨牙大面积龋病儿童208例，按随机数表法分为观察组和对照组，每组104例。观察
组患儿采用活髓保存后PMC修复方案，对照组患儿采用传统复合树脂充填治疗方案。比较两组患儿修复成功率、修复失败原
因，同时比较修复18个月后两组患儿家属VAS评分。结果：两组患儿治疗后12个月内复查，观察组患儿修复成功率均略高于
对照组，但差异均无统计学意义(P ＞0.05)；治疗18个月后，观察组患儿修复成功率(87.74%)显著高于对照组(71.25%)，差
异具有统计学意义(P ＜0.05)；两组患儿修复失败原因主要是继发龋和充填体脱落、破裂，其中观察组患儿继发龋的发生率
(3.77%)明显低于对照组(15.94%)，组间比较差异有统计学意义(P ＜0.05)；观察组患儿家属VAS评分为(7.42±1.46)分，对
照组为(8.20±1.31)分，观察组较对照组低，但组间比较差异无统计学意义(P ＞0.05)。结论：PMC对乳磨牙大面积龋病儿童
活髓保存后的修复效果显著，可有效恢复正常咬合关系，维持儿童正常咀嚼功能及颌面发育，有效弥补复合树脂充填体易脱
落、破裂以及继发龋发生率较高等缺点，值得在临床中推广应用。

Abstract:
Abstract: Objective To investigate the effect of Preformed Metal Crown (PMC) on the preservation of pulp in large rickets
of children with deciduous teeth. Methods A total of 208 children with large rickets who were treated in our hospital from
January 2017 to January 2018 were enrolled. The patients were divided into observation group and control group according
to the random number table method, 104 cases in each group. In the observation group, the PMC repair protocol was used
after the preservation of the pulp, and the control group was treated with the traditional composite resin fi lling treatment. The
success rate of repair and the cause of repair failure were compared between the two groups.as well as the VAS scores of the
families of the two groups. Results The recovery rate of the children in the observation group was slightly higher than that in
the control group within 12 months after treatment. The difference was not statistically signifi cant (P ＞0.05). After 18 months
of treatment, the observation group suffered from the observation group. The success rate of repair (87.74%) was signifi cantly
higher than that of the control group (71.25%), and the difference was statistically signifi cant (P ＜0.05). The causes of repair
failure in both groups were mainly secondary sputum and fi lling detachment and rupture. The incidence of secondary spasm in
the observation group (3.77%) was signifi cantly lower than that in the control group (15.94%). The difference between the two
groups was statistically signifi cant (P ＜0.05). The VAS score of the family members in the observation group was (7.42±1.46)
points, and that of the control group was (8.20±1.31)points. The observation group was lower than the control group, but there
was no statistical difference (P ＞0.05). Conclusion PMC can signifi cantly restore the normal occlusal relationship of children
with large rickets of deciduous teeth, and can effectively restore normal occlusion. It can effectively compensate the
detachment, rupture and secondary sputum of composite resin fi llings. Higher shortcomings are worthy of promotion and
application in the clinic.
