新型光固化硅酸钙材料在乳牙牙髓切断术中的疗效观察

Effect of a new light-curable calcium silicate-based material in pulpotomy of deciduous teeth

摘要

摘要:
目的比较新型光固化硅酸钙材料TheraCal LC与生物陶瓷材料iRoot BP Plus在乳牙牙髓切断术中的临床效果。
方法将118颗去腐露髓的患儿乳牙随机分为试验组(n=59)和对照组(n=59), 并分别采用TheraCal LC和iRoot BP Plus行乳牙牙髓切断术。术后6、12、18个月复查, 比较2组的临床成功率和影像学成功率。
结果术后6个月，试验组和对照组治疗成功率均为100.0%; 术后12个月，试验组和对照组治疗成功率分别为98.3%和96.6%; 术后18个月，试验组和对照组治疗成功率分别为85.7%和86.7%; 2组术后6、12、18个月的治疗成功率比较，差异均无统计学意义(P>0.05)。充填治疗与预成冠修复的患牙术后成功率比较，差异无统计学意义(P>0.05)。
结论 TheraCal LC与iRoot BP Plus用于乳牙牙髓切断术的成功率均较高，但TheraCal LC在临床中更具操作便捷、价格便宜、操作时间短等优势。

Abstract:
Objective To compare the clinical efficacy between a new light-curable calcium silicate-based material TheraCal LC and bioceramic material iRoot BP Plus in treating pulpotomy of deciduous teeth.
Methods A total of 118 pulp-exposed deciduous teeth after removal of necrotic tissue were randomly divided into trail group (n=59) and control group (n=59), and were respectively treated with TheraCal LC and iRoot BP Plus for pulpotomy of deciduous teeth. At 6, 12 and 18 months after operation, the clinical success rate and imaging success rate of the two groups were compared.
Results Six months after operation, the therapeutic success rate was 100.0% in the trail group and the control group; at 12 months after operation, the therapeutic success rates of the trail group and the control group were 98.3% and 96.6% respectively; at 18 months after operation, the therapeutic success rates of the trail group and the control group were 85.7% and 86.7% respectively; there were no significant differences in the therapeutic success rates between the two groups at 6, 12 and 18 months after operation (P>0.05). There was no significant difference in the success rate between the methods of filling treatment and the preformed crown repair (P>0.05).
Conclusion Both TheraCal LC and iRoot BP Plus have high success rates in the pulpotomy of deciduous teeth, but TheraCal LC has more advantages such as convenient operation, low price and short operation time in clinical practice.
