摘要： 目的:分析广泛型侵袭性牙周炎(GAgP)患者咀嚼肌肌电活动,并以正常人为对照,探讨GAgP患者咀嚼肌肌电表现及对咀嚼肌功能的影响。方法:测量并记录正常组和牙周炎组双侧颞肌前束(TA)、咬肌(MM)、二腹肌前腹(DA)及胸锁乳突肌(SCM)在下颌不同位置时肌电值。利用配套软件进行肌电值分析,获得连续肌电值的平均值,计算肌电值不对称指数。比较两组咀嚼肌肌电值有无统计学差异;比较两组在最大紧咬时,TA和MM肌电值不对称指数有无统计学差异。结果:在下颌姿势位时,牙周炎组的TA、MM、DA和SCM的肌电值均大于正常组;在牙尖交错位( ICP)最大紧咬时,牙周炎组TA、MM肌电值均小于正常组(P＜0.001);在下颌姿势位时,牙周炎TA、MM、DA和SCM均有微小肌电活动,其中TA＞MM＞DA;最大紧咬时TA＞MM;前伸运动时DA＞MM＞TA;后退位时 DA＞MM,TA＞MM,差异均有统计学意义(P＜0.05);ICP最大紧咬时,牙周炎组较正常组左右侧TA和MM肌电值不对称指数高,并且存在统计学差异(P＜0.05)。结论:GAgP患者因牙周组织受损而降低了咀嚼功能,存在咀嚼活动不平衡及肌肉功能异常。

Abstract: Objective: To analyze the masticatory muscle electromyographic activity in generalized aggressive periodontitis (GagP) patients. Methods: The electromaography of anterior temporalis (TA), masseter muscle (MM), digastric anterior (DA) and sternocleidomastiod (SCM) were recorded in differential mandibular positions. The electromaography (EMG) was analyzed using bundled software. Results:In the resting position, the electromyography values of anterior temporalis, masseter muscle, digastric anterior and sternocleidomastiod of periodontitis group were higher than those of the control group. In the intercuspal position, the electromyography values of anterior temporalis, masseter muscle of periodontitis group were lower than those of control group (P＜0.001). In the resting position, anterior temporalis, masseter muscle, digastric anterior and sternocleidomastiod of periodontitis group showed low electromyographic activities, TA＞MM＞DA. In the intercuspal position, TA＞MM;In the protrusive position, DA＞MM＞TA;In the retruded contact position, DA＞MM,TA＞MM. The differences were statistically significant (P＜0.05). In the intercuspal position, the asymmetry index of electromyography values of anterior cntemporalis, masseter muscle of periodontitis group were lower than those of the control group(P＜0.05). Conclusion: The masticatory function of the patients with GagP was impaired by the damaged periodontium. The patients with GagP showed unbalanced chewing activity, muscle dysfunction and masticatory muscle tension imbalance in left and right side.
