To assess Early Childhood Caries by measuring the dmft, Significant Caries Index (SiC), pufa, and caries-free status in informal settlements outside Cape Town, South Africa over a 10-year period.
A series of cross-sectional studies over a 10-year period (2009-2019). Surveys were carried out in preschools in informal settlements. A total of 5090 children aged from 1 to 5 years of age were examined.
For 1- to 3-year-olds, the mean dmft was 4.33 ± 1.55, and for 4- and 5-year-olds, it was 6.34 ± 1.48. The difference in dmft for 1- to 3-year-olds increased but did not differ statistically between 2009 and 2019. For 4-5 years old, there was an increase over time. For 1- to 3-year-olds, the mean pufa was 0.34 ± 0.28, and for 4- to 5-year-olds, it was 0.63 ± 0.59. For 1- to 3- and for 4- to 5-year-olds, there was a statistically significant, lower pufa 2009-2019. For 1- to 3-year-olds, the mean SiC was 11.0 ± 2.35, and for 4- to 5-year-olds, it was 12.05 ± 1.89. There was a difference in SiC for 1-3 and for 4- to 5-year-olds, which was higher but did not differ statistically 2009-2019. Among 1- to 3-year-olds, 32.1% were assessed as caries-free. Among 4- to 5-year-olds, 16.0% were caries-free. There was a statistically significant, lower number of caries-free 1- to 3-year-old and 4- 5-year-old children 2009-2019.
The mean dmft has been found to be continuously high from 2009 to 2019. The SiC score remained unchanged, whereas pufa was significantly lower. The frequency of caries-free children was lower over time.
通过测量乳牙龋失补牙面数（dmft）、龋均（SiC）、致龋性菌斑（pufa）以及无龋状态，对南非开普敦以外非正式定居点10年间的幼儿龋齿情况进行评估。
在10年期间（2009 - 2019年）开展了一系列横断面研究。在非正式定居点的幼儿园进行调查。共检查了5090名1至5岁的儿童。
1至3岁儿童的平均dmft为4.33 ± 1.55，4至5岁儿童的平均dmft为6.34 ± 1.48。1至3岁儿童的dmft差异有所增加，但在2009年至2019年期间无统计学差异。4至5岁儿童的dmft随时间增加。1至3岁儿童的平均pufa为0.34 ± 0.28，4至5岁儿童的平均pufa为0.63 ± 0.59。在2009年至2019年期间，1至3岁以及4至5岁儿童的pufa均有统计学意义的降低。1至3岁儿童的平均SiC为11.0 ± 2.35，4至5岁儿童的平均SiC为12.05 ± 1.89。1至3岁与4至5岁儿童的SiC存在差异，且较高，但在2009年至2019年期间无统计学差异。1至3岁儿童中，32.1%被评估为无龋。4至5岁儿童中，16.0%无龋。在2009年至2019年期间，1至3岁以及4至5岁无龋儿童数量有统计学意义的减少。
2009年至2019年期间，平均dmft持续处于较高水平。SiC评分保持不变，而pufa显著降低。随着时间推移，无龋儿童的频率降低。
