The study describes tooth mortality levels and pattern of prosthetic treatments in a sample of 1744 Chinese aged 20-80 yr who are residents of Beijing area. Complete edentulousness was rarely seen before the age of 60 yr. Beyond this age up to 26% were edentulous, depending on age and sex. The mean number of teeth present ranged from 10.0 to 29.7 depending on age, sex, and area of residence. Below the age of 60 yr very few persons had experienced extensive loss of teeth but thereafter the number of teeth missing was substantially increased. Prosthetic treatments in the form of partial dentures, crowns, and bridges were frequently observed even in the younger age groups. In all age groups the number of teeth exhibiting caries lesions involving the pulp was much higher than the number of teeth exhibiting extensive mobility. Although many people retain a high number of teeth even late in life our findings indicate a substantial need for, in particular, relief of pain services. Concurrently, emphasis must be placed on preventive programs aiming at interfering with ongoing disease.
该研究描述了居住在北京地区的1744名年龄在20至80岁的中国人样本中的牙齿死亡率水平和修复治疗模式。60岁之前很少见到全口无牙的情况。超过这个年龄，根据年龄和性别，有高达26%的人无牙。根据年龄、性别和居住地区，现存牙齿的平均数量在10.0至29.7颗之间。60岁以下很少有人经历过大量牙齿缺失，但此后缺失牙齿的数量大幅增加。即使在较年轻的年龄组中，也经常观察到局部义齿、牙冠和牙桥等修复治疗。在所有年龄组中，出现累及牙髓的龋损的牙齿数量远高于出现广泛松动的牙齿数量。尽管许多人即使到晚年仍保留大量牙齿，但我们的研究结果表明，尤其迫切需要缓解疼痛的服务。同时，必须强调旨在干预正在发生的疾病的预防计划。
