摘　　要：目的分析在为年轻恒牙因外伤致牙髓坏死(Pulpnecrosis,PN)患者行牙髓血运重建治疗的过程中联合运用氢氧化钙粉末与洗必泰所获得的临床效果。方法随机在天津市滨海新区塘活口腔医院接受年轻恒牙因外伤致PN后行牙髓血运重建治疗的患者中抽取76例开展试验研究,根据随机数字表法将患者分为各有38例患者的实验组与对比组,实验组患者在牙髓血运重建中联合运用氢氧化钙粉末与洗必泰治疗,对比组则运用三联糊剂治疗,分析比较两组患者的临床治疗效果与相关治疗指标。结果两组患者治疗效果、不良反应发生率以及治疗后疼痛评分、牙齿松动度、牙龈肿胀程度、CBCT检查结果和细菌培养阳性率均存在显著差异,P<0.05。两组患者治疗前疼痛评分、牙齿松动度、牙龈肿胀程度、CBCT检查结果和细菌培养阳性率均无显著差异,P>0.05。结论实施年轻恒牙因外伤致PN后行牙髓血运重建治疗的过程中,氢氧化钙粉末联合洗必泰的应用效果较为显著,有助于患者相关临床指标的更好改善,值得予以临床推广。Objective To analyze the clinical efficacy of combined use of carbon hydroxide powder and chlorhexidine in the treatment of Pulp necrosis(PN)caused by trauma in young permanent teeth.Methods A total of 76 patients who received pulpal revascularization in hospital due to PN caused by trauma of young permanent teeth were randomly selected to conduct an experimental study.According to the random number table method,the patients were divided into an experimental group with 38 patients in each group and a comparison group.The experimental group was treated with calcium hydroxide powder and chlorhexidine combined in pulpal revascularization,while the comparison group was treated with triple paste.The clinical therapeutic effect and related therapeutic indexes of the two groups were analyzed and compared.Results There were significant dfferences in treatment effect,incidence of adverse reactions,pain score,tooth looseness,gingival swelling,CBCT results and positive rate of bacterial culture between two groups(P<0.05).There were no significant differences in pain score,tooth looseness,gingival swelling,CBCT results and positive rate of bacterial culture between two groups before treatment(P>0.05).Conclusion The application of calcium hydroxide powder combined with chlorhexidine in the treatment of pulp revascularization after PN injury in young permanent teeth has a significant effect,which is helpful to better improve the relevant clinical indicators of patients,and is worthy of clinical promotion.
