The purpose of this study was to determine the prevalence and severity of dental caries and dental fluorosis, as well as various other oral conditions, in 2378 subjects (ages seven to 60) living in the fluoridated area of Khouribga and the non-fluoridated area of Beni Mellal, Morocco. The community index of dental fluorosis (CFI) ranged from 1.99 to 2.80 in the high-fluoride area: Over 90% of the population was affected, and more than one-third of the subjects showed moderate dental fluorosis. However, in Beni Mellal, more than 96% of the dentate subjects examined were free of dental fluorosis, and the CFI of 0.02 was considered not significant. Significant differences were observed between the two areas with respect to caries prevalence. DMFT and DMFS indices were markedly lower in the fluorosis area of Khouribga. The oral conditions of subjects appeared to be better in Khouribga, where the gingival and calculus indices were significantly lower than in Beni Mellal. The analyses of covariance showed no significant differences in plaque accumulation (PI) between the Khouribga and Beni Mellal samples. However, a close statistical correlation was found between PI and GI in Beni Mellal and Khouribga.
本研究的目的是确定生活在摩洛哥胡里卜盖（Khouribga）氟化地区和贝尼迈勒（Beni Mellal）非氟化地区的2378名受试者（年龄在7至60岁之间）的龋齿、氟斑牙以及各种其他口腔疾病的患病率和严重程度。在高氟地区，社区氟斑牙指数（CFI）在1.99至2.80之间：超过90%的人口受到影响，超过三分之一的受试者表现出中度氟斑牙。然而，在贝尼迈勒，接受检查的有牙受试者中超过96%没有氟斑牙，CFI为0.02被认为无显著意义。在龋齿患病率方面，两个地区之间观察到显著差异。胡里卜盖氟斑牙地区的DMFT和DMFS指数明显较低。胡里卜盖受试者的口腔状况似乎更好，其牙龈指数和牙石指数明显低于贝尼迈勒。协方差分析表明，胡里卜盖和贝尼迈勒样本之间的菌斑积聚（PI）没有显著差异。然而，在贝尼迈勒和胡里卜盖，PI与GI之间发现了密切的统计相关性。
