Data on the dental health of Australian school children from 1977 to 1985 have previously been reported. Significant features included a secular decline in caries experience as defined by the number of decayed, missing and filled teeth in both the deciduous dentition (dmft index) and permanent dentition (DMFT index), and a change in the distribution of caries experience within the child population in Australia, indicated by increasingly smaller percentages of children accounting for greater proportions of total disease experience. The aim of the present paper was to extend the annual reporting on caries experience in Australia up to and including 1993, and to document the change in the distribution of caries within the child population since 1977. In addition, the data are compared with dental targets for children for the year 2000 in Australia and internationally. Caries data were obtained for the years 1977-1993 for children who were patients at School Dental Services in each State and Territory of Australia. Caries experience was recorded by uncalibrated dentists and dental therapists during routine dental examinations. From 1977-89 data were weighted by State and Territory estimated resident populations. From 1989, the data were stratified according to age, year, and State, and weighted to reflect proportions in the national estimated resident population for each State/age stratum. Between 1977 and 1993 there has been a decline in caries experience for 6 year old children from a dift++ of 3.13 to a dmft of 1.90, and an increase in the per cent with dmft = 0 from 33.1 per cent to 53.2 per cent with dmft = 0 in 1993. Over the same time period the DMFT for 12 year olds reduced from 4.79 to 1.10 and the per cent while DMFT = 0 increased from 10.5 per cent to 53.1 per cent. Projection of the decline in DMFT indicates the dental health target for 12 year old children of DMFT = 1.0 by the year 2000 should have been achieved by the end of 1995.
此前已报道过1977年至1985年澳大利亚学龄儿童的牙齿健康数据。显著特征包括龋病患病情况呈长期下降趋势，这一趋势通过乳牙列（dmft指数）和恒牙列（DMFT指数）中龋、失、补牙的数量来定义；澳大利亚儿童群体中龋病患病情况的分布也发生了变化，即患龋病儿童的比例越来越小，但他们占总疾病经历的比例却越来越大。本文的目的是将澳大利亚龋病患病情况的年度报告更新至1993年（包括1993年），并记录自1977年以来儿童群体中龋病分布的变化。此外，还将这些数据与澳大利亚和国际上2000年儿童的牙齿健康目标进行比较。龋病数据取自1977年至1993年期间澳大利亚各州和领地学校牙科服务机构的儿童患者。龋病患病情况由未经校准的牙医和牙科治疗师在常规牙科检查中记录。1977年至1989年的数据按各州和领地的估计常住人口进行加权。从1989年起，数据按年龄、年份和州进行分层，并加权以反映每个州/年龄层在全国估计常住人口中的比例。1977年至1993年期间，6岁儿童的龋病患病情况有所下降，龋失补牙面数（dift++）从3.13降至dmft 1.90，dmft = 0的儿童百分比从33.1%增至1993年的53.2%。在同一时期，12岁儿童的DMFT从4.79降至1.10，DMFT = 0的儿童百分比从10.5%增至53.1%。DMFT下降趋势的预测表明，到1995年底应已实现2000年12岁儿童DMFT = 1.0的牙齿健康目标。
