The existence of a secular trend in the distribution of occlusal patterns was studied in two generations of children. Study models and demographic data of a sample of 265 children from the previous generation (group A) and recordings of clinical examinations of 988 children from the present generation (group B) served as the data base for this study. Children in whom caries affected the occlusion and those in the deciduous dentition stage were excluded. Thus, occlusal analysis was performed for 102 children in group A and 703 in group B. A dramatic decrease was found in the prevalence of caries affecting the occlusion. No difference existed between the two groups with respect to molar and canine anteroposterior relationships. However, there was a decrease in the prevalence of normal occlusion accompanied by an increase of Class I malocclusion.
在两代儿童中研究了咬合模式分布的长期趋势。上一代265名儿童的研究模型和人口统计学数据（A组）以及当代988名儿童的临床检查记录（B组）作为本研究的数据库。龋齿影响咬合的儿童和处于乳牙列阶段的儿童被排除在外。因此，对A组的102名儿童和B组的703名儿童进行了咬合分析。发现影响咬合的龋齿患病率显著下降。两组在磨牙和尖牙前后关系方面没有差异。然而，正常咬合的患病率有所下降，同时I类错牙合患病率有所上升。
