摘要

目的:研究四种不同的治疗方法对颞下颌盘复位移位患者咬肌和颞肌肌肉活动的影响。对象和方法:共选择100例患者。其中女性64例,男性36例,平均年龄31岁左右。所选患者平均分为四组:第一组患者采用行为治疗;II组患者行低水平激光治疗;III组患者接受前路复位夹板;IV组采用平面夹板。采用表面肌电图(EMG)评价咬肌和颞肌的活动。组间比较采用单因素方差分析进行统计学分析。各组治疗前后比较采用配对t检验(p<0.05)。结果:治疗6个月后,除行为治疗组外,各组肌肉活动度均有显著提高。平板夹板组最高,行为治疗组最低。结论:咬合夹板治疗可明显提高咀嚼肌活动,其他治疗方法可作为辅助治疗。

Effect of four conservative treatment methods on the muscular activity of masseter and temporalis muscles for subjects with temporomandibular joint disc displacement with reduction
Objective: This study was conducted to study the effect of four different treatment methods on the muscular activity of masseter and temporalis muscles of patients with temporomandibular disc displacement with reduction. Subjects and methods: Total 100 patients were selected. The selected patients were 64 females and 36 males with mean age about 31 years. The selected patients were divided equally into four groups: patients in group I were treated with behavioral therapy; patients of group II had a low-level laser therapy; patients of group III received anterior repositioning splints; patients of group IV received a flat plane splints. Activities of masseter and temporalis muscles were evaluated using surface electromyography (EMG). Statistical analysis was done using one-way ANOVA test for comparison between groups. Within each group, comparison between baseline and after treatment was done using paired t-test (p<0.05). Results : All groups showed significant increase in the muscular activity after 6 months of treatment except behavioral therapy group. The flat splint showed the highest value, and the behavioral therapy group showed the lowest value. Conclusion : Treatment with occlusal splints significantly increased the masticatory muscles activity, and the other lines of treatment can be considered as an adjunctive therapy.
