A system of oral health determination in which times between eruption of teeth and first restorations because of caries is measured is applied in a retrospective analysis of oral health data relating to rural health centres in Finland.
The retrospective analysis was carried out using data relating to three health centres in different parts of Finland. The times between eruption and the placement of the first restorations in subjects up to 18 years of age were investigated.
Between 10% and 25% of all permanent molar teeth were filled in the year of tooth emergence--the 'immediate posteruptive step'. A steadily increasing restoration placement rate--the 'ascending growth phase'--was observed after the 'posteruptive step'. The restoration rate was found to plateau 5-8 years after eruption--the 'retardation phase'.
Restoration increment curves with longitudinal measurements are believed to be a sensitive indication of oral health at both individual and population levels.
应用一种口腔健康测定系统，该系统测量牙齿萌出与首次因龋齿进行修复之间的时间，对芬兰农村健康中心的口腔健康数据进行回顾性分析。
使用芬兰不同地区三个健康中心的数据进行回顾性分析。调查了18岁及以下受试者牙齿萌出与首次修复之间的时间。
在牙齿萌出的当年，即“萌出后即刻阶段”，所有恒牙磨牙中有10%至25%进行了填充。在“萌出后阶段”之后，观察到修复率稳步上升——“上升增长阶段”。发现修复率在牙齿萌出5至8年后趋于平稳——“迟缓阶段”。
纵向测量的修复增量曲线被认为是个体和群体层面口腔健康的敏感指标。
