A group of 483 men, all of whom were 68 or 69 yr old and had lived for a long time in the city of Malmö were examined with regard to number of teeth present, removable dentures, fixed bridges, and tooth spaces. 76.4% had one or more natural teeth remaining, 59.2% had removable dentures, and 0.2% were edentulous and without dentures. The mean number of teeth present in a fixed dentition calculated on dentate subjects was 16.21 +/- 8.02, including teeth replaced by pontics and 15.0 +/- 7.44 when natural teeth only were recorded. The number of bridges was high, 28.8% of natural dentate persons having bridgework. This cohort had fewer remaining teeth than in similar groups in other areas of Sweden, but more fixed bridges. 19.5% had open tooth spaces corresponding to one or more teeth in the visible parts of the dental arches. The availability of dentistry has been extremely good in Malmö and financial support for all types of dental care has been provided for all inhabitants since 1974. In spite of this, a low number of remaining teeth and many untreated tooth spaces in visible part of the dental arches were found, though on the other hand much fixed bridgework was found. It appears from the present study that the population tends to polarize into two groups, namely one group which takes advantage of the dental services and one which does not.
对一组483名男性进行了检查，他们年龄均为68或69岁，长期居住在马尔默市，检查内容包括现存牙齿数量、可摘假牙、固定桥和牙间隙。76.4%的人有一颗或多颗天然牙留存，59.2%的人有可摘假牙，0.2%的人无牙且未佩戴假牙。在有牙列的受试者中计算得出的固定牙列中现存牙齿的平均数量为16.21±8.02颗，包括由桥体替代的牙齿，若仅记录天然牙则为15.0±7.44颗。固定桥的数量很多，28.8%的有天然牙列的人有桥体修复。与瑞典其他地区的类似群体相比，该队列留存的牙齿较少，但固定桥较多。19.5%的人在牙弓可见部分有相当于一颗或多颗牙齿的牙间隙。自1974年以来，马尔默的牙科服务可及性一直非常好，为所有居民提供了各类牙科护理的经济支持。尽管如此，仍发现牙弓可见部分留存的牙齿数量较少且有许多未治疗的牙间隙，不过另一方面也发现了大量的固定桥修复。从本研究来看，人群似乎倾向于两极分化为两组，即一组利用牙科服务，另一组则不利用。
