Data on prevalence of dental caries and increment of treated teeth are reported from children receiving dental care from a Public Child Dental Health Service established in 1959. Data are obtained from records in three periods: 1961-63, 1968-70, and 1976-78. The prevalence of dental caries in 8-year-olds (n approximately 300) after initial dental care remained at the same level in 1961 and 1968. In 1976 the prevalence was reduced by 30%. Increments of treated teeth in 8-11-year-old children (n approximately 1600) were reduced by more than 50% from 1961-63 to 1968-70, but remained then at the same level in 1976-78. Increments of restored surfaces of permanent incisor teeth were reduced by 90% in 1968-70 and further by 50% to almost nil in 1976-78. These data suggest a remarkable reduction in caries activity in the population, presumably resulting from the school-based preventive programs introduced in 1960, and widespread use of fluoridated dentifrice in Denmark from 1968. The apparently maintained level of restorative work in the last period is discussed and interpreted in the light of the more favorable dentist to population ratio and the markedly reduced intervals of recall visits in the same period.
本文报告了1959年成立的公共儿童牙科保健服务机构所诊治儿童的龋齿患病率及治疗牙齿增量的数据。数据取自三个时期的记录：1961 - 1963年、1968 - 1970年和1976 - 1978年。接受初次牙科护理后8岁儿童（约300人）的龋齿患病率在1961年和1968年保持在同一水平。1976年患病率降低了30%。8 - 11岁儿童（约1600人）的治疗牙齿增量从1961 - 1963年到1968 - 1970年减少了50%以上，但在1976 - 1978年保持在同一水平。恒牙切牙修复面的增量在1968 - 1970年减少了90%，在1976 - 1978年又进一步减少了50%，几乎为零。这些数据表明该人群的龋齿活动显著减少，推测这是由于1960年实施的基于学校的预防计划以及1968年起丹麦广泛使用含氟牙膏所致。根据同期更有利的牙医与人口比例以及显著缩短的复诊间隔，对最后一个时期修复工作水平明显维持的情况进行了讨论和解读。
