舌肌功能训练联合固定矫治器治疗早期牙源性错牙合畸形患儿的效果

Effects of tongue muscle function training combined with fixed orthodontic appliance in treatment of children with early odontogenic malocclusion deformity

目的:观察舌肌功能训练联合固定矫治器治疗早期牙源性错牙合畸形患儿的效果。方法:选取2020年2月至2023年2月该院收治的66例早期牙源性错牙合畸形患儿进行前瞻性研究,按照随机数字表法将其分为对照组和观察组各33例。对照组采用固定矫治器治疗,观察组在对照组基础上联合舌肌功能训练治疗,两组均治疗6个月。比较两组临床疗效,治疗前后咀嚼肌肌电指标(咬肌、颞肌、二腹肌募集电位)水平、咀嚼功能[Karaduman咀嚼行为量表(KCPS)]评分和牙周指标(菌斑指数、软垢指数)水平。结果:观察组治疗总有效率为90.91%(30/33),高于对照组的69.70%(23/33),差异有统计学意义(P<0.05);治疗后,观察组咬肌、颞肌、二腹肌募集电位均高于对照组,差异有统计学意义(P<0.05);治疗后,观察组KCPS评分低于对照组,差异有统计学意义(P<0.05);治疗后,观察组菌斑指数、软垢指数均低于对照组,差异有统计学意义(P<0.05)。结论:舌肌功能训练联合固定矫治器治疗早期牙源性错牙合畸形患儿可提高治疗总有效率和咀嚼肌肌电指标水平,降低咀嚼功能评分和牙周指标水平,效果优于单纯固定矫治器治疗。

Objective:To observe effects of tongue muscle function training combined with fixed orthodontic appliance in treatment of children with early odontogenic malocclusion deformity.Methods:A prospective study was conducted on 66 children with early odontogenic malocclusion admitted to the hospital from February 2020 to February 2023.According to the random number table method,they were divided into control group and observation group,33 cases in each group.The control group was treated with fixed orthodontic appliance,while the observation group was treated with tongue muscle function training on the basis of that of the control group.Both groups were treated for 6 months.The clinical efficacy,the masticatory muscle EMG indexes(masseter muscle,temporal muscle,digastricus recruitment potential)levels,the chewing function[Karaduman chewing performance scale(KCPS)]score,and the periodontal indexes(plaque index,debris index)levels were compared between the two groups before and after the treatment.Results:The total effective rate of the observation group was 90.91%(30/33),which was higher than 69.70%(23/33)of the control group,and the difference was statistically significant(P<0.05).After the treatment,the recruitment potential of masseter muscle,temporal muscle and digastric muscle in the observation group were higher than those in the control group,and the differences were statistically significant(P<0.05).After the treatment,the KCPS score of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).Further,after the treatment,the plaque index and debris index in the observation group were lower than those in the control group,and the differences were statistically significant(P<0.05).Conclusions:Tongue muscle function training combined with fixed orthodontic appliance in the treatment of the children with early odontogenic malocclusion can improve the total effective rate of treatment and the levels of masticatory muscle electromyographic indexes,and reduce the levels of masticatory function score and periodontal index.Moreover,it is superior to single e fixed orthodontic appliance treatment.
