In 1973 the fluoridation of drinking water in the Dutch town of Tiel was discontinued. In order to monitor the effect of this measure, the caries experience in 15-year-old children was investigated annually from 1979 to 1988, both in Tiel and in Culemborg. In the latter town the drinking water had never been fluoridated. The caries data of 15-year-old children examined between 1968 and 1969 in Tiel (children having used fluoridated water from birth) and Culemborg were used as historical controls. In Tiel the mean number of DMFS increased between 1968/69 and 1979/80 from 10.8 to 12.7 (+18%) and decreased to 9.6 (-26%) in the following years; in 1987/88 the mean DMFS was 11% lower than in 1968/69. In Culemborg the mean DMFS score decreased between 1968/69 and 1987/88 from 27.7 to 7.7 (-72%). In 1968/69 the mean DMFS score in Tiel was 61% lower and in 1987/88 17% higher than in Culemborg. The question as to whether water fluoridation would have had an additional effect if it had been continued (presuming the application of existing preventive measures) cannot be answered, as there are no remaining communities with fluoridated water in The Netherlands.
1973年，荷兰小镇蒂尔停止了饮用水氟化处理。为监测这一措施的效果，1979年至1988年期间，每年对蒂尔和库伦堡15岁儿童的龋齿患病情况进行调查。在库伦堡，饮用水从未进行过氟化处理。将1968年至1969年期间在蒂尔（从出生就饮用氟化水的儿童）和库伦堡接受检查的15岁儿童的龋齿数据用作历史对照。在蒂尔，1968/69年至1979/80年期间，DMFS（龋失补牙面数）平均数从10.8增加到12.7（增长18%），在随后几年降至9.6（下降26%）；1987/88年的平均DMFS比1968/69年低11%。在库伦堡，1968/69年至1987/88年期间，DMFS平均得分从27.7降至7.7（下降72%）。1968/69年，蒂尔的平均DMFS得分比库伦堡低61%，1987/88年则比库伦堡高17%。由于荷兰已没有仍在进行饮用水氟化处理的社区，因此无法回答如果继续进行饮用水氟化处理（假设采用现有的预防措施）是否会产生额外效果这一问题。
