The timing of the placement of first fillings because of caries on different permanent tooth surfaces was determined at three health centers in Finland. The 927 subjects analyzed were born either in 1970-71 o4 in 1980-81. Basically, two different types of filling placement site were identified: 1) fissures and pits and 2) proximal and smooth surfaces. In some fissures and pits a 'post-eruptive'--that is, fillings placed in the year of emergence--was observed. This step had decreased markedly in the cohort born in 1980-81. The curves plateaued (retardation phase) at 50-60% for the occlusal surfaces in first molars for the children born in 1970-71 and at 20-30% for the younger cohort. The time without any filling varied from 1 to 7 years on smooth surfaces, and some surfaces remained totally filling-free. The filling placement curves followed the pattern of caries attack and can thus be used as an indicator of dental health.
在芬兰的三个健康中心确定了因不同恒牙表面龋齿而首次补牙的时间。所分析的927名受试者出生于1970 - 1971年或1980 - 1981年。基本上，确定了两种不同类型的补牙部位：1）窝沟和点隙；2）邻面和平滑面。在一些窝沟和点隙中观察到“萌出后”补牙情况，即牙齿萌出当年进行补牙。这一情况在1980 - 1981年出生的队列中明显减少。1970 - 1971年出生儿童的第一恒磨牙咬合面补牙曲线在50% - 60%处趋于平稳（延迟阶段），而较年轻队列则在20% - 30%处趋于平稳。平滑面无补牙的时间从1年到7年不等，有些表面始终未进行补牙。补牙曲线遵循龋齿发病模式，因此可用作口腔健康指标。
