摘　　要：目的:研究聚乳酸(PLA)可吸收根管桩联合氰基丙烯酸酯粘接剂在婴幼儿前牙残冠修复中的应用价值。方法:选取2017年1月~2018年12月我院收治的前牙残冠婴幼儿患者100例,按照完全随机法将所有患儿分为对照组和PLA组各50例。对照组采用玻璃纤维短桩联合双重固化树脂粘接剂修复,PLA组采用PLA可吸收根管桩联合氰基丙烯酸酯粘接剂修复。评价两组患儿牙龈情况、咬合功能、牙龈沟炎症反应、临床疗效,并随访统计不良事件发生情况。结果:两组患儿修复后牙龈指数、咬合力高于修复前,牙龈出血指数低于修复前,且PLA组患儿牙龈指数、咬合力高于对照组,牙龈出血指数低于对照组,差异有统计学意义(P<0.05)。PLA组修复后牙龈沟炎症指标TNF-α、CRP、IL-8、IL-6表达水平均低于对照组,差异有统计学意义(P<0.05)。PLA组修复成功率显著高于对照组(P<0.05),PLA组不良事件总发生率显著低于对照组(P<0.05)。结论:婴幼儿前牙残冠修复治疗中应用PLA可吸收根管桩联合氰基丙烯酸酯粘接剂可改善牙龈状态,抑制TNF-α、CRP、IL-8、IL-6等炎症因子表达,对牙龈的刺激较小,可降低不良事件的发生,修复成功率较高。Objective:To study the application of polylactic acid(PLA)absorbable root canal post combined with cyanoacrylate adhesive in the restoration of infant anterior crown.Methods:A total of 100 infants with anterior residual crown admitted to our hospital from January 2017 to December 2018 were selected and randomly divided into control group and PLA group with 50 cases each.The control group was repaired with glass fiber short post combined with double curing resin adhesive,while the PLA group was repaired with PLA absorbable root pipe post combined with cyanoacrylate adhesive.The gingival condition,occlusal function,gingival sulcus inflammation,and clinical efficacy of two groups were evaluated,and the incidence of adverse events was followed up.Results:The gingival index and bite force after repair were higher than those before repair,and the gingival bleeding index was lower than that before repair.In addition,the gingival index and bite force of the PLA group were higher than those of the control group,and the gingival bleeding index was lower than that of the control group(P<0.05).After repair,the levels of TNF-α,CRP,IL-8,and IL-6 in the PLA group were all lower than those in the control group(P<0.05).The success rate of repair in PLA group was significantly higher than that in control group(P<0.05).The total incidence of adverse events in PLA group was significantly lower than that in the control group(P<0.05).Conclusion:PLA absorbable root canal post combined with cyanoacrylate adhesive can improve gingival state,inhibit the expression of TNF-α,CRP,IL-8,IL-6,and other inflammatory indexes in the treatment of residual crown of anterior teeth in infants,which has less stimulation to gingiva,reduces the occurrence of adverse events,and has a high success rate of restoration.
