Influence of Stomatognathic System and Systemic Condition on Gravity Fluctuation

Abstract

Some of the patients with temporpmandibular disorders (TMD) complain about not only major TMD symptoms but also other symptoms like stiff shoulder, dizziness, headache and so on. Many of researchers have been reported on the influence of occlusion and stomatognathic system on systemic symptom and posture by using a gravity fluctuation analysing system. So we evaluated the influence of stomatognathic system and systemic condition on gravity fluctuation. Ten volunteers were examined for their systemic symptoms and measured and recorded gravity fluctuation. General symptom, posture or facial symmetry, and temporomandibular joint (TMJ) or occlusion were recorded as the score. Category of general symptoms included dizziness, headache, stiff shoulder, numbness of hand, leg, and lumbago. Category of posture or facial symmetry included height of eyes, lip and shoulder and shift of nose. Category of TMJ and occlusion included pain of masseter and temporalis muscle, TMJ sound, opening disturbance, occlusal disharmony, and jaw shift. The area of gravity fluctuation was measured by using the gravity fluctuation analysing system. The score of general symptom was 2.8±2.04. The score of posture or facial symmetry was 2.4±1.26. The score of TMJ or occlusion was 2.2±1.32. There was no significant correlation between the area of gravity fluctuation and each three categories, but the tendency of positive correlation was seen.
