摘要
目的观察富含血小板纤维蛋白(PRF)及矿物三氧化物凝聚体(MTA)材料支架和iRoot BP Plus支架在年轻恒牙再生性牙髓治疗中的应用效果。方法回顾性分析2017年4月至2019年4月于榆林市中医医院口腔科治疗的68例(68牙)龋齿、73例(82牙)外伤引发年轻恒牙再生性牙髓患儿的临床资料。按照治疗方案的不同分为4个亚组,其中龋齿引发年轻恒牙再生性牙髓患儿为A组、B组,外伤引发年轻恒牙再生性牙髓患儿为C组、D组,A组、C组使用PRF及MTA材料支架实施牙髓手术,B、D组使用iRoot BP Plus支架实施牙髓手术。术后随访24个月,比较两组患儿的临床疗效、患牙恢复状况、根管根尖改善状况。结果A组患牙的治疗总有效率为94.12%,明显高于B组的67.65%,差异有统计学意义(P<0.05);C组患牙的治疗总有效率为87.80%,明显高于D组的60.98%,差异有统计学意义(P<0.05);A组患牙的牙髓活力正常、根尖孔封闭、萌出高度增加、牙体色泽正常分别占79.41%、94.12%、67.65%、82.35%,明显高于B组的47.06%、55.88%、38.24%、50.00%,差异均具有统计学意义(P<0.05);C组患牙的牙髓活力正常、根尖孔封闭、萌出高度增加、牙体色泽正常分别占78.05%、78.05%、60.98%、73.17%,明显高于D组的51.22%、51.22%、36.59%、43.90%,差异均具有统计学意义(P<0.05);治疗前,A组患牙的根管壁厚度、根管长度分别为(2.06±0.25)mm、(12.52±1.60)mm,同B组的(2.09±0.29)mm、(12.47±1.65)mm比较差异均无统计学意义(P>0.05);治疗后,A组患牙的根管壁厚度、根管长度分别为(2.53±0.29)mm、(16.85±2.03)mm,明显高于B组的(2.19±0.27)mm、(15.09±1.92)mm,差异均有统计学意义(P<0.05);治疗前,C组患牙的根管壁厚度、根管长度分别为(2.10±0.26)mm、(12.79±1.48)mm,同D组的(2.07±0.28)mm、(12.73±1.46)mm比较差异均无统计学意义(P>0.05);治疗后,C组患牙的根管壁厚度、根管长度分别为(2.50±0.31)mm、(16.91±1.92)mm,明显高于D�
Objective To observe the effect of platelet-rich fibrin(PRF)and mineral trioxide aggregates(MTA)material scaffolds and iRoot BP Plus scaffolds in the treatment of young permanent teeth with regenerative endodontics.Methods The clinical data of 68 cases(68 teeth)of young children with regenerative endodontics of permanent teeth caused by dental caries and 73 cases(82 teeth)of young children with regenerative endodontics of permanent teeth caused by trauma,who were treated in the Chinese Medicine Hospital of Yulin City from April 2017 to April 2019,were retrospectively analyzed.According to the different treatment options,the patients were divided into 4 subgroups:the 68 cases caused by dental caries were divided into group A and B,and the 73cases induced by trauma were divided into group C and D.The endodontic surgery was performed with a PRF and MTA scaffold in group A and C and with iRoot BP Plus scaffold in groups B and D.After 24 months of postoperative follow-up,the clinical curative effect,the restoration status of the affected tooth,and the improvement of the root canal apex of the two groups were compared.Results The total effective rate in group A was 94.12%,which was significantly higher than 67.65%in group B(P<0.05);the total effective rate of group C was 87.80%,which was significantly higher than 60.98%of group D(P<0.05).The normal pulp vitality,apical foramen closure,eruption height increase,and normal tooth color in group A accounted for 79.41%,94.12%,67.65%,and 82.35%,respectively,which were significantly higher than corresponding 47.06%,55.88%,38.24%,and 50.00%in group B(all P<0.05);those in group C accounted for 78.05%,78.05%,60.98%,and73.17%,respectively,which were significantly higher than corresponding 51.22%,51.22%,36.59%,and 43.90%in group D(all P<0.05).Before treatment,the root canal wall thickness and root canal length of the teeth in group A were(2.06±0.25)mm and(12.52±1.60)mm,which were not statistically significant different from(2.09±0.29)mm and(12.47±1.65)mm in group B(P>0.05);afte
