The loss of teeth is known to influence the mastication of foods and nutritional status. Therefore, we hypothesize that poor dentition status can impair the systemic health of the aged. To clarify the influence of dentition status on deterioration in physical ability, mental impairment, and mortality, we conducted a six-year prospective cohort study of the institutionalized elderly living in 29 of the 30 institutions for the elderly in Kitakyushu, Japan. Bivariate analysis revealed that worse dentition status at baseline led to significantly worse physical and mental impairment, and higher mortality. In a multiple logistic regression analysis, the physical ability of edentulous subjects without dentures significantly deteriorated compared with that of dentate subjects with 20 or more teeth. The six-year mortality rate of the edentulous subjects without dentures was significantly higher than that of the subjects with 20 or more teeth. Poorer dentition status, especially edentulousness without dentures, may therefore be related to deterioration in the systemic health of the aged.
众所周知，牙齿缺失会影响食物咀嚼和营养状况。因此，我们推测牙列状况不佳会损害老年人的全身健康。为了阐明牙列状况对身体机能衰退、认知障碍和死亡率的影响，我们对日本北九州市30所养老院中的29所机构养老的老年人进行了为期六年的前瞻性队列研究。双变量分析显示，基线时较差的牙列状况会导致身体和认知障碍显著加重，以及死亡率升高。在多元逻辑回归分析中，无牙且未佩戴假牙的受试者的身体机能与有20颗或更多牙齿的有牙受试者相比显著恶化。无牙且未佩戴假牙的受试者的六年死亡率显著高于有20颗或更多牙齿的受试者。因此，较差的牙列状况，尤其是无牙且未佩戴假牙，可能与老年人全身健康的衰退有关。
