In 1982 a combined sociodental research project was started in the city of Groningen in order to gain insight into the dental and social reasons for total extraction. 91% of the dentists in the city participated in this study by collecting the extracted teeth, filling out a questionnaire and asking their patients to fill out another questionnaire concerning the behavioral aspects of total tooth loss. 78% of the 134 patients returned the questionnaire. In this article the caries status in relation to the social background and dental attendance pattern has been described. The mean age at the time of extraction was 44.2 yr. The patients were a good cross-section of the Dutch population as regards education level, type of health insurance and sex. The average number of teeth was 14.2. The average DEMFT value was 22.8. Although regular attenders had less D-teeth than irregular attenders they had an average of 3.5 teeth with active caries. Regular attenders had more F-teeth but less sound teeth than irregular attenders. The contribution of the dental health care system to the dental health of the population is discussed.
1982年，在格罗宁根市启动了一项社会牙科联合研究项目，旨在深入了解全口拔牙的牙科和社会原因。该市91%的牙医参与了这项研究，他们收集拔除的牙齿、填写问卷，并让患者填写另一张关于全口牙齿缺失行为方面的问卷。134名患者中有78%返回了问卷。本文描述了与社会背景和看牙模式相关的龋病状况。拔牙时的平均年龄为44.2岁。在教育水平、医疗保险类型和性别方面，这些患者是荷兰人口的一个良好样本。平均牙齿数量为14.2颗。平均乳牙及恒牙龋失补牙面数（DEMFT）值为22.8。虽然定期看牙者的龋坏牙齿比不定期看牙者少，但他们平均有3.5颗牙齿有活动性龋病。定期看牙者的充填牙齿比不定期看牙者多，但完好牙齿比不定期看牙者少。文中讨论了牙科保健系统对人群口腔健康的贡献。
