Caries experience and enamel fluorosis prevalence in 8-year-old children belonging to different socio-economic classes were determined in two Chilean twin cities that are served by optimally fluoridated community water from the same waterworks facility. Low socio-economic status (LSES) children had a higher mean dmft and DMFT indices (P < 0.001) than high socioeconomic status (HSES) children. Prevalence of enamel fluorosis in the permanent teeth of LSES children was 0.79, significantly higher (chi 2 = 9.0; P < 0.003) than the value 0.59 found in HSES children. The proportion of Dean's scores 2, 3, 4 and 5 in first molars, mandibular and maxillary incisors in LSES children was higher than in HSES children (P < 0.001). Differences in prevalence and severity of enamel fluorosis between both groups are tentatively attributed to a different pattern of tap water and tea consumption at pre-school ages. Suggestions are advanced to minimize the undesirable prevalence and severity of enamel fluorosis.
在智利两座由同一水厂提供最佳氟化社区用水的双子城，确定了不同社会经济阶层8岁儿童的龋齿经历和釉质氟斑牙患病率。社会经济地位低（LSES）的儿童比社会经济地位高（HSES）的儿童有更高的平均乳牙龋失补牙面数（dmft）和恒牙龋失补牙面数（DMFT）指数（P < 0.001）。LSES儿童恒牙釉质氟斑牙患病率为0.79，显著高于HSES儿童中发现的0.59（χ² = 9.0；P < 0.003）。LSES儿童第一磨牙、下颌和上颌切牙中Dean指数2、3、4和5的比例高于HSES儿童（P < 0.001）。两组之间釉质氟斑牙患病率和严重程度的差异初步归因于学前年龄阶段不同的自来水和茶饮用模式。提出了一些建议以尽量减少釉质氟斑牙的不良患病率和严重程度。
