The purpose of this study was to evaluate a risk-based dental caries prevention program at an urban pediatric primary care clinic serving low-income residents.
A demonstration caries prevention trial lasting 26 months was conducted with 219 6- to 27-month-old children. A "prevention" group of 6- to 15-month-old children (initial visit) were compared at the end of the trial with a "comparison" group at their initial visit. The latter children were patients of the same clinic who were 12 months older (18-27 months). Preventive services included: caries-risk assessments; mutans streptococci (MS) monitoring; fluoride varnish applications; dental health counseling; referral for dental treatment, if indicated; and periodic recalls.
Prevention group children at the last recall experienced fewer mean carious dental surfaces (0.1 vs 1.29, P=.01) and over 8-fold less MS (P=.01) than comparison group subjects at their initial visit. The number of precavitated lesions was not significantly different
Administration of prevention measures was shown to reduce dental caries experience in low socioeconomic status infants and toddlers, and oral MS levels were a reliable indicator of future caries status. Outcomes support establishment of caries prevention programs at urban primary care pediatric clinics.
本研究旨在评估一项基于风险的龋齿预防项目,该项目在一家为低收入居民服务的城市儿科初级保健诊所开展。
对219名6至27个月大的儿童进行了为期26个月的龋齿预防示范试验。将6至15个月大儿童的“预防”组(初次就诊)在试验结束时与同一家诊所12个月大(18至27个月)的“对照组”初次就诊时的情况进行比较。预防服务包括:龋齿风险评估;变形链球菌(MS)监测;氟化物涂膜应用;口腔健康咨询;如有需要,转诊进行牙科治疗;以及定期回访。
在最后一次回访时,预防组儿童的平均龋面数(0.1比1.29,P = 0.01)比对照组初次就诊时少,变形链球菌数量减少超过8倍(P = 0.01)。早期龋损的数量没有显著差异。
结果表明,采取预防措施可减少社会经济地位较低的婴幼儿患龋齿的情况,口腔变形链球菌水平是未来龋齿状况的可靠指标。研究结果支持在城市初级保健儿科诊所建立龋齿预防项目。
