摘要:

目的：探讨断冠再接术和活髓切断术治疗外伤冠折露髓年轻恒前牙的临床疗效。方法：选取2018年9月-2019年9月笔 者医院牙体牙髓科就诊的90例外伤冠折露髓年轻恒前牙患儿为观察对象，按冠折断片保留完整与否分为断冠再接组45例（共 45颗患牙）和树脂修复组45例（共49颗患牙），两组均行口腔检查和活髓切断术治疗，在此基础上断冠再接组给予断冠再接 术修复牙冠，树脂修复组给予树脂修复牙冠，比较两组患儿随诊临床疗效和术后24个月冠方修复体临床美学效果、牙周相 临床指标及主观满意度。结果：经过1～2年的临床随诊观察，两组1～6个月成功率均为100%，12个月、24个月后断冠 再接组成功率分别为78.94%和67.65%，树脂修复组成功率分别为68.42%和55.56%，差异均无统计学意义(χ2 =1.086， 1.079，P＞0.05)；断冠再接组边缘染色和边缘密合性评分均高于树脂修复组(P＜0.05)，两组断裂和保留、术后敏感性及 继发龋评分比较差异均无统计学意义(P＞0.05)；断冠再接组牙周临床各指标均低于树脂修复组（P＜0.05）；断冠再接组美 观性与舒适度评分均高于树脂修复组(P＜0.05)，两组咀嚼功能和固位功能评分比较差异均无统计学意义（P＞0.05）。结 论：断冠再接术联合活髓切断术治疗可提高外伤冠折露髓年轻恒前牙的中、短期临床疗效，具有较佳临床美学效果，对患儿 牙周组织健康影响较小，有利于提高治疗满意度，值得临床推广应用。

Abstract:

Objective To observe and explore the clinical efficacy of broken crown reattachment and vital pulpotomy in the treatment of young permanent anterior teeth with traumatic crown fracture and pulp exposure. Methods 90 children with young permanent anterior teeth with traumatic crown fracture and pulp exposure in the hospital department of dentistry and endodontics between September 2018 and September 2019 were selected as the observation subjects. According to whether the crown fragments were kept intact or not, the children were divided into broken crown reattachment group (45 cases, 45 teeth) and resin restoration group (45 cases, 49 teeth). Both groups underwent oral examination and vital pulpotomy, and on this basis, the broken crown reattachment group was given broken crown reattachment, and the resin restoration group was treated with resin crown restoration. The follow-up clinical effi cacy, and clinical aesthetic eff ect of crown restoration, clinical periodontal indicators and subjective satisfaction at 24 months after surgery were compared between the two groups of children. Results After 1 to 2 years of clinical follow-up observation, the success rates of both groups were 100% and 100% after 1 to 6 months, and the success rates after 12 months and 24 months were 78.94% and 67.65% in broken crown reattachment group and were 68.42% and 55.56% in resin restoration group respectively (χ2 =1.086, 1.079, all P＞0.05). The scores of marginal staining and marginal adaptation of broken crown reattachment group were higher than those of resin restoration group (P＜0.05), but there were no significant differences in the scores of fracture and retention, postoperative sensitivity and secondary caries between the two groups (P＞0.05). The clinical periodontal indicators of broken crown reattachment group were lower than those of resin restoration group (P＜0.05). The scores of aesthetics and comfort were higher in broken crown reattachment group than those in resin restoration group (P＜0.05), and there were no statistical differences in the scores of masticatory function and retentionfunction between the two groups (P＞0.05). Conclusion The combination of broken crown reattachment and vital pulpotomy can improve the short-term and medium-term clinical efficacy of young permanent anterior teeth with traumatic crown fracture and pulp exposure. It has a better clinical aesthetic effect and smaller impact on the health of periodontal tissues, and it is conducive to improving the treatment satisfaction, thus it is worthy of clinical promotion and application.
