Using laser Doppler flowmetry (LDF), the blood microcirculation of the masseter muscle was studied in one healthy male subject performing clenching and grinding of the teeth. LDF suggested that blood flow was increased during clenching, and that it did not change appreciably during grinding. In one female patient (acute pain from myofibrostic lesion in masseter muscle), LDF suggested that flow within the lesion was increased during rest (postural position). In three healthy adults, subjected to simulated traumatic occlusion of the incisors, LDF suggested an absence of consistent changes in pulpal blood flow.
使用激光多普勒血流仪（LDF），对一名进行咬牙和磨牙动作的健康男性受试者的咬肌血液微循环进行了研究。LDF显示，咬牙时血流量增加，而磨牙时血流量没有明显变化。在一名女性患者（咬肌肌纤维病变引起的急性疼痛）中，LDF显示病变部位在休息（姿势位）时血流量增加。在三名接受模拟切牙创伤性咬合的健康成年人中，LDF显示牙髓血流量没有持续一致的变化。
