The aim of this study was to analyse the stomatognathic system of adult women with chronic allergic rhinitis by means of molar bite force and electromyographic activity of the masseter and temporalis muscles.
A total of 26 subjects were screened and divided into two distinct groups: chronic allergic rhinitis group (n = 13) and healthy control group (n = 13). Subjects were assessed by maximal molar bite force (right and left) and normalized electromyographic activity of mandibular tasks (rest, right and left laterality, protrusion and maximal voluntary contraction). Data were submitted to Student's t test (< .05).
There was significant difference in right ( = .03) and left ( = .04) maximal molar bite force with force reduction in the chronic allergic rhinitis group. There was significant difference in normalized electromyographic activity in maximal voluntary contraction in the right ( =.01) and left ( = .01) temporalis muscles, with increased electromyographic activity in the masticatory muscles for the chronic allergic rhinitis group.
The results suggest that chronic allergic rhinitis in adult women promoted negative changes in the electromyographic activity of temporalis muscles in maximal voluntary contraction and maximal molar bite force. Rhinitis, occlusal force, electromyography, masticatory muscles.
本研究旨在通过磨牙咬合力以及咬肌和颞肌的肌电图活动来分析成年慢性变应性鼻炎女性的口颌系统。
共筛选出26名受试者并分为两个不同的组：慢性变应性鼻炎组（n = 13）和健康对照组（n = 13）。通过最大磨牙咬合力（右侧和左侧）以及下颌任务（休息、右侧和左侧偏侧、前伸和最大自主收缩）的标准化肌电图活动对受试者进行评估。数据采用Student's t检验（<.05）。
慢性变应性鼻炎组右侧（= .03）和左侧（= .04）最大磨牙咬合力存在显著差异，咬合力降低。右侧（= .01）和左侧（= .01）颞肌最大自主收缩时标准化肌电图活动存在显著差异，慢性变应性鼻炎组咀嚼肌的肌电图活动增加。
结果表明成年女性慢性变应性鼻炎在最大自主收缩和最大磨牙咬合力时会导致颞肌肌电图活动出现负面变化。鼻炎、咬合力、肌电图、咀嚼肌。
