The trend of dental caries in Chandigarh school children over a sixteen year period, studied by almost the same authors and using the same recording criteria of WHO reveals a continuous decline in 12 and 15 year children but a slight increase in the dental caries status of 5-6 year children. In 1977, the mean DMFT of 12 and 15 year children was 3.88 and 4.74 respectively. In 1985, it decreased to 1.38 in 15 year olds (12 year children not recorded) and in 1993 it marginally decreased to 1.12 +/- 1.35, much lower than the figure of 3.88 in 1977. In 5-6 year children, mean dmft/dmfs of 2.69 +/- 1.45 and 6.06 +/- 9.77 was found to be slightly higher as compared to the earlier caries prevalence figures (deft + DMFT-2.6 in 1977 and 2.26 in 1985).
昌迪加尔学童龋齿发病趋势在十六年期间由几乎相同的作者进行研究，并采用世界卫生组织相同的记录标准，结果显示12岁和15岁儿童龋齿情况持续下降，但5至6岁儿童的龋齿状况略有上升。1977年，12岁和15岁儿童的平均龋失补牙面数（DMFT）分别为3.88和4.74。1985年，15岁儿童的该数值降至1.38（未记录12岁儿童的数据），1993年略微降至1.12±1.35，远低于1977年的3.88。在5至6岁儿童中，发现平均乳牙龋失补牙面数/恒牙龋失补牙面数（dmft/dmfs）为2.69±1.45和6.06±9.77，与早期龋齿患病率数据（1977年乳牙龋失补牙面数 + 恒牙龋失补牙面数为2.6，1985年为2.26）相比略高。
