Dental fluorosis is the most common and prominent symptom in the early stage of chronic fluorosis, which is caused by excessive fluorine intake during tooth development. In severe cases, it may be accompanied by skeletal fluorosis. There are also systemic damages to the nervous system, cardiovascular system, endocrine system and so on. The pathogenesis of dental fluorosis is not totally clear, which may be a complex pathological process involving both genetic and environmental factors. The prevalence of dental fluorosis has an upward trend arround the world, thus certain public prevention and treatment strategies need to be taken. This article focuses on the prevalence, etiology, diagnosis and scoring system, as well as the public prevention and treatment strategies, of dental fluorosis, so that to provide reference for the research and prevention of the disease.
氟牙症是在牙发育形成期间，由于机体摄氟过多导致牙釉质发育缺陷而引起的牙体硬组织改变，是慢性氟中毒早期最常见且突出的症状，严重者可同时伴有氟骨症，并引起心血管、中枢神经和内分泌等多系统损伤。氟牙症涉及的发病机制尚未完全明确，可能是基因与环境共同作用的复杂病理过程。鉴于氟牙症的发病率在全球呈上升趋势，本文重点对氟牙症的流行情况、病因研究进展、诊断与评分体系以及公共防治策略进行阐述，为氟牙症的研究与公共卫生策略制定提供参考。.
