摘　　要：目的评估正畸-牙周联合治疗对替牙期儿童错位伴继发性咬合创伤牙齿局部牙周组织的疗效。方法选取2016年1月—2018年1月在江苏省徐州市中心医院口腔科就诊的50例替牙期儿童,依据错位牙是否伴有继发性咬合创伤将其分为两组,研究组(n=25)为错位牙伴继发性咬合创伤的儿童;对照组(n=25)为牙齿有错位但不伴有咬合创伤的儿童。所有患儿在牙周-正畸联合治疗前先行牙周状态评估,对比两组患者治疗前、后错位牙牙周袋探针深度(PD)、牙龈指数(GI)、出血指数(BI)和菌斑指数(PI)。结果治疗前研究组错位继发咬合创伤牙齿平均牙周指标PD、GI、BI、PI均高于对照组,差异有统计学意义(P<0.05);治疗后两组错位牙局部牙周状况较治疗前均有明显改善,差异均有统计学意义(P<0.05);而两组治疗后的PD、GI、BI、PI比较,差异无统计学差异(P>0.05)。结论对于替牙期出现错位伴继发性咬合创伤牙齿的儿童,应给予早期干预,正畸-牙周联合治疗不仅能去除咬合创伤、排齐牙齿,而且有利于患牙牙周组织的改建和修复。Objective To evaluate the effect of periodontal-orthodontic treatment on the local periodontal tissue of children with malposed teeth and secondary occlusal trauma in mixed dentition period.Methods From January 2016 to January 2018,50 children in mixed dentition period were selected from Department of Stomatology,Xuzhou Central Hospital.They were divided into two groups according to the malposed teeth whether or not with secondary occlusal trauma,children in the study group with malposed teeth and secondary occlusal trauma(n=25),children in the control group with malposed teeth without secondary occlusal trauma(n=25).The periodontal status of all children were evaluated at the first visit before orthodontic-periodontal treatment.Probing pocket depth(PPD),gingival index(GI),bleeding index(BI)and plaque index(PI)of the two groups were compared before and after orthodontic-periodontal treatment.Results The average periodontal index PD,GI,BI and PI of malposed teeth with secondary occlusal trauman in the study group before treatment were higher than those in the control group,the differences were statistically significant(P<0.05).After treatment,the local periodontal status of malposed teeth in the two groups was significantly improved compared with that before treatment,the differences were statistically significant(P<0.05).But there was no significant difference in PPD,GI,BI and PI between two groups after treatment(P>0.05).Conclusion Early intervention should be given to the mixed dentition children with malposed teeth and a secondary occlusal trauma.A combined orthodontic-periodontal therapy can not only eliminate occlusal trauma and align teeth,but also help to reconstruct and repair periodontal tissue.
