摘要/Abstract

摘要： 目的:评价活髓切断术联合透明预成冠修复乳前牙外伤的临床疗效。方法:选择西安交通大学口腔医院2022年3月—2023年2月收治的82例乳前牙外伤冠折露髓患儿,随机分为试验组和对照组,每组各41例。两组患儿均行活髓切断术,试验组采用透明预成冠修复,对照组采用复合树脂修复。治疗后1个月,比较两组牙龈指数(gingival index,GI)和菌斑指数(plaque index,PLI)。治疗后6、12和18个月,比较两组修复成功率。结果:治疗后1个月,试验组GI和PLI显著低于对照组（P<0.05）。两组治疗后6、12个月修复成功率相比,差异无统计学意义（P>0.05）;治疗后18个月,试验组修复成功率显著高于对照组（P<0.05）。结论:活髓切断术联合透明预成冠修复乳前牙外伤不仅显著提高修复成功率,还能有效改善牙龈健康,减少菌斑堆积,并保持患牙长期稳定,具有良好的美学效果和功能。

Abstract: PURPOSE: To evaluate the curative effect of pulpotomy combined with prefabricated transparent crown for traumatic anterior primary tooth. METHODS: A total of 82 children with traumatic crown fractures and pulp exposure of anterior primary teeth treated at Xi'an Jiaotong University Stomatology Hospital from March 2022 to February 2023 were selected and randomly divided into experimental group and control group, with 41 cases in each group.Both groups were treated with pulpotomy,the experimental group was treated with prefabricated transparent crown and the control group was treated with composite resin.One month after treatment, gingival index (GI) and plaque index (PLI) were compared between the two groups. At 6, 12 and 18 months after treatment, the success rate of restoration was compared between the two groups. RESULTS: One month after treatment, GI and PLI of the experimental group were significantly lower than those of the control group(P<0.05). There was no significant difference in the success rate of restoration between the two groups at 6 and 12 months after treatment (P>0.05), and the success rate of restoration in the experimental group was significantly higher than that in the control group at 18 months after treatment(P<0.05). CONCLUSIONS: Pulpotomy combined with prefabricated transparent crown restoration not only significantly improves the success rate of restoration for traumatic anterior primary tooth,but also effectively enhances gingival health, reduces plaque accumulation and maintains long-term tooth stability,with good aesthetic effects and functionality.
