Dental fluorosis is endemic in the Rift Valley in Africa, especially around volcanic areas, due to the high fluoride content in daily drinking water.
This study evaluates the oral health status and types of occlusion in a school population, and to assess the possible association between dental fluorosis and other pathologies such as decay, gingivitis and periodontitis.
An observational study of 581 individuals recruited from a public secondary school in Arusha, Northern Tanzania was undertaken. The indices used were: the Silness & Löe Plaque Index, the Community Periodontal Index and the Decayed/Missing/Filled index. Descriptive statistical analyses were performed and a chi-square test was used to assess the associations between independent variables.
Almost all the school children evaluated (96.73%) presented Angle class I dental occlusion, and 75.22% presented some degree of dental fluorosis. Most of the population (511, 87.95%) showed bleeding on probing. A moderate/high degree of some dental pathology (DMF score) was recorded in 14.46%. The association between dental fluorosis, gingival bleeding and tooth decay indicated a higher concentration of pathology in groups with more severe fluorosis (<0.05).
In this large population sample, both tooth decay and gingivitis were significantly associated with moderate or severe dental fluorosis.
由于日常饮用水中氟含量高，非洲裂谷地区，特别是火山地区，氟斑牙流行。
本研究评估了一个学校人群的口腔健康状况和咬合类型，并评估了氟斑牙与其他疾病（如龋齿、牙龈炎和牙周炎）之间的可能关联。
对坦桑尼亚北部阿鲁沙市一所公立中学的 581 名学生进行了一项观察性研究。使用的指标有：Silness & Löe 菌斑指数、社区牙周指数和龋齿/缺失/补牙指数。进行了描述性统计分析，并使用卡方检验评估了独立变量之间的关联。
评估的几乎所有学童（96.73%）都呈现 Angle Ⅰ类牙咬合，75.22%都有一定程度的氟斑牙。大多数人群（511 人，87.95%）存在探诊出血。记录到中度/高度的一些牙齿病变（DMF 评分）为 14.46%。氟斑牙、牙龈出血和龋齿之间的关联表明，氟斑牙越严重，病变的浓度越高（<0.05）。
在这个大样本人群中，龋齿和牙龈炎与中度或重度氟斑牙显著相关。
