title: [Masticatory function and life style in aged].
abstract: Elderly people gain enjoyment in their remaining years from eating, speaking and tasting things, and they find that the oral function is necessary to arouse in them a desire to work for society, in addition to looking after their own health, they find that over function is important. Recently, more attention has come to be paid to one's external appearance. Even if function is impaired, appearance has a strong influence on the feeling of leading a worth-while life. Though increasing age brings a steady loss of teeth, it is unlikely that physiological change resulting from tooth decay and disease are the cause of tooth loss. Degradation of the hard tissue caused by decay is unavoidable. Unless the decayed area is removed and the teeth are repaired with artificial materials, the function of the affected tooth is permanently lost. Moreover, as decay progresses and periodontal disease worsens the state of a given area, extraction becomes necessary. This is the process by which teeth are lost. However, even if teeth are lost, masticatory function may be restored through the use of dentures. Recently, we carried out a survey which showed that a group of elderly people with good masticatory functions were more healthy and lived longer than a group of elderly people with reduced physical functions (weight, grasping strength, balance, bone salt volume) and poor masticatory function.
