摘要
本研究探讨了牙髓血运重建术中根管封药药物对治疗年轻恒牙牙髓坏死效果及影像学指标的变化。选取80例年轻恒牙牙髓坏死的患儿(80颗牙)进行回顾性研究,根据治疗方法分为研究组[44例(44颗牙)]和对照组[36例(36颗牙)]。两组患者均采用血运重建术治疗,研究组术中采用氢氧化钙根管封药治疗,对照组采用三联抗生素糊剂根管封药治疗;对比两组患儿治疗前后的临床疗效,并采用口腔颌面锥形束CT(CBCT),检查两组患儿治疗前后不同时间的患牙牙冠根比、患牙根管壁厚度。治疗12个月后,研究组患儿的患牙牙冠根比低于对照组,治疗6个月及治疗12个月后,研究组的患牙根管壁厚度测定值大于对照组(P<0.05);治疗3个月后,研究组患儿的治疗效果优于对照组(P<0.05)。牙髓血运重建术+氢氧化钙根管封药方法治疗年轻恒牙牙髓坏死效果较好,采用CBCT能观察到治疗后患儿的恒牙牙根再发育情况,有利于提高治疗效果。
This study investigated the effect of root canal sealing drugs on the treatment of pulp necrosis in young permanent teeth and the changes of imaging indicators during pulp revascularization.Eighty children(80 teeth)with pulp necrosis in young permanent teeth were retrospectively studied.According to the treatment method,44 cases(44 teeth)in the study group and 36 cases(36 teeth)in the control group.Both groups were treated with revascularization.The study group was treated with calcium hydroxide root canal sealing medicine,and the control group was treated with root canal sealing drug with triple antibiotic paste.The clinical efficacy of the two groups before and after treatment was compared,and Cone Beam CT(CBCT)was used to examine the crown-to-root ratio and root canal wall thickness of the affected teeth at different times before and after treatment in the two groups.After 12 months of treatment,the crown-to-root ratio of the affected teeth in the study group was lower than that in the control group.After 6 months of treatment and 12 months of treatment,the measured value of the root canal wall thickness in the study group was greater than that in the control group(P<0.05).After 3 months of treatment,the therapeutic effect of the study group was better than that of the control group(P<0.05).Pulp revascularization combined with calcium hydroxide root canal sealing is effective in treating pulp necrosis of young permanent teeth.CBCT can observe the redevelopment of permanent teeth in children after treatment,which is beneficial to improve the treatment effect.
