Surveys of dental caries prevalence were carried out from 1970-1993 in schoolchildren of the city of Zurich. DMFT experience declined by 68 to 80%, while the average dmft decreased by 48-53% (ages 7 to 9). From 1988 to 1993, the average DMFT decreased further in the age group of 12- and 14-year-olds; in the ages 7 to 10, however, neither the DMFT nor the dmft showed a decline. In children who had of late immigrated, DMF levels were 2 to 3 times higher than in the children holding Swiss citizenship.
1970年至1993年期间，对苏黎世市的学童进行了龋齿患病率调查。恒牙龋失补牙面数（DMFT）经验值下降了68%至80%，而乳牙龋失补牙面数（dmft）平均值下降了48%至53%（7至9岁）。1988年至1993年期间，12岁和14岁年龄组的恒牙龋失补牙面数（DMFT）平均值进一步下降；然而，在7至10岁年龄段，恒牙龋失补牙面数（DMFT）和乳牙龋失补牙面数（dmft）均未下降。近期移民儿童的龋失补牙面数（DMF）水平比拥有瑞士公民身份的儿童高2至3倍。
