In the present study, we assessed the relation between dental status and fall in a sample of 253 volunteers(105 men and 148 women) free-living adults and elderly people in Japan by a questionnaire survey. The mean group rate and number of people who had fallen during the past 3-year period were 24. 1% and 3. 36 times, respectively. Among those who had fallen, the proportion who had lost the occlusal supporting zone was 29. 7%, while the proportion who maintained the occlusal supporting zone was 21. 4%. Then, we also investigated the influence of change in dental occlusion on the stabilization of posture stance disturbed by electrical stimulation of unilateral lower limb in healthy 5 adults volunteers with dental splint occluded anterior teeth only and 5 healthy elderly people with denture. When the occlusal supporting zone was transiently lost by insertion of dental splint, both and maximum ground reaction force were increased. In the elderly people with dentures, maximum ground reaction forces in both anterior-posterior and medial-lateral directions with teeth clenching on wearing denture were smaller than that with teeth clenching on wearing no denture. The present results suggested that maintenance of dental occlusion throughout life would be possibly effective for not only preserving better the masticatory function but also preventing falls later in life.

在本研究中，我们评估了牙齿状态和下降的样本253名志愿者（105名男性和148名女性）自由生活的成年人和老年人在日本的问卷调查之间的关系。在过去3年期间，平均群体比率和跌倒人数为24人。1%和3。分别是36次。在跌倒的人中，失去咬合支持区的比例为29。7%，而保持咬合支持区的比例为21。百分之四然后，我们还研究了牙齿咬合变化对单侧下肢电刺激干扰的姿势稳定性的影响，其中5名健康成年志愿者仅使用牙夹板咬合前牙，5名健康老年人使用义齿。当咬合支持区暂时丧失时，最大地面反力和最大地面反力均增加。戴义齿的老年人，戴义齿时咬牙时前后和内外向最大地面反力均小于不戴义齿时咬牙时。目前的结果表明，在整个生命中保持牙齿咬合不仅可以更好地保持咀嚼功能，而且还可以防止以后的生活中的福尔斯。
