A dental health survey was carried out in the Arussi province in Ethiopia. The survey comprised 1,700 persons between 6 and 54 years of age in five age groups from four areas of the province. The present paper deals with findings on dental fluorosis and dental caries. Dental fluorosis was found in 18% of the subjects, mainly in a very mild form. The fluoride content of the water (0.2-0.3 part/10(6) F-) in combination with a high tea consumption was assumed to give a fluoride intake optimal for caries prevention. The prevalence of dental caries was low. Thirty-eight percent of the 6-7-year-old group had decayed primary teeth and 51% of the total sample had decayed permanent teeth. Comparisons with a study from 1958 revealed that the prevalence of dental caries had increased in the last few decades, probably due to the recently adopted habit of using sugar in the diet.
在埃塞俄比亚的阿鲁西省开展了一项口腔健康调查。该调查涵盖了该省四个地区五个年龄组的1700名6至54岁的人员。本文论述了有关氟斑牙和龋齿的调查结果。在18%的受试者中发现了氟斑牙，主要为非常轻微的形式。水中的氟含量（0.2 - 0.3 份/10⁶ F⁻）加上较高的茶消耗量被认为使氟摄入量对于预防龋齿而言处于最佳水平。龋齿患病率较低。在6 - 7岁年龄组中，38%的儿童乳牙有龋坏，在整个样本中，51%的人恒牙有龋坏。与1958年的一项研究相比表明，在过去几十年中龋齿患病率有所上升，这可能归因于最近在饮食中使用糖的习惯。
