In 2005 a dental survey of the prevalence of caries among 6- and 12-year-old schoolchildren in The Hague was carried out. In the case of the 12-year-olds, the prevalence of dental erosion was also studied. The sample consisted of 814 students in twelve primary schools in The Hague. The results reveal that since the previous study, in 2002, the trend in the direction of an increasing percentage of children with deciduous caries-free teeth and permanent caries-free teeth had continued. In the case of the children who were not caries-free, it was noticeable that, in general, the number of new dental caries (dmfs- and DMFS-score) had not changed in the period 1996-2005, while the number of restorations among the 6- and 12-year olds had decreased. The mean restorative index in the deciduous dentition of 6-year-olds decreased from approximately 40% in 1996 to approximately 20% in 2005; with respect to permanant dentition among 12-year-olds, the percentage decreased from more than 90% to 60%. The percentage of 12-year-olds with dental erosion in 2005 remained unchanged as compared with 2002: 24%. The research revealed that there was no increase in dental caries or dental erosion among the 6- and 12-year-old school children in The Hague.
2005年，针对海牙6岁和12岁学童的龋齿患病率开展了一项牙科调查。对于12岁的儿童，还研究了牙齿侵蚀的患病率。样本包括海牙12所小学的814名学生。结果显示，自2002年的上一项研究以来，乳牙无龋和恒牙无龋儿童的比例呈上升趋势。对于非无龋儿童，值得注意的是，在1996年至2005年期间，新龋齿（dmfs和DMFS评分）的数量总体上没有变化，而6岁和12岁儿童的补牙数量有所减少。6岁儿童乳牙列的平均修复指数从1996年的约40%降至2005年的约20%；对于12岁儿童的恒牙列，这一比例从90%以上降至60%。与2002年相比，2005年12岁儿童牙齿侵蚀的比例保持不变：为24%。研究表明，海牙6岁和12岁学童的龋齿或牙齿侵蚀情况没有增加。
