Materials and methods: The neuronal activities related to unilateralmastication were detected with functional magnetic resonance imaging in 10healthy volunteers.
Results (1)The semiminute masticatory performance in the youth of normal occlusion on autonomous mastication was significantly higher than that on unilateralmastication (P<0.05);
结果①自由咀嚼的半分钟咀嚼效能高于限定用单侧咀嚼的效能（P＜0．05）；
3
Objective To study the effect of unilateral chew on temporomandibular joint and mastication muscles.
