Abstract:
Objective To evaluate masticatory performance and life quality of children with ectodermal dysplasia(ED) after prosthetic rehabilitation.Methods Six children with ED received denture restoration and 18 healthy children were involved in this study.The surface electromyography(EMG) of masseter(MM) and anterior temporalis(TA) during clenching and chewing movement were recorded.The EMG amplitude,area,asymmetry index of total and activity index of MM/TA were compared at each stage.The masticatory efficiency was measured with spectrophotometer.The life quality was assessed using visual analogue scale questionnaire.Results The EMG amplitude of MM and TA during chewing in ED Group were 41.7％ and 45.6％ of the control group respectively,the area were 35.9％ and 36.0％ respectively.Significant difference in asymmetry index of total during clenching was observed between the two groups (P＜0.05) but not during chewing(P＞0.05).The differences of activity index of MM/TA during clenching and chewing between the two groups were not detected(P＞0.05).The masticatory efficiency of ED group was 67.2％ of the control group.The score of chewing function in children with ED after prosthetic rehabilitation was three times higher than before,and no difference was present between the two groups (P＞0.05).Conclusions Early prosthetic rehabilitation can significantly improve the masticatory performance and life quality of children with ED.
