which is the clinical manifestations of dental fluorosis

Dental fluorosis, dental fluorosis, or spots, also known as tooth enamel, fluoride major damage to tooth enamel developmental stages of ameloblastoma, therefore, only too much fluoride during tooth development stage of mineralization into the body, dental fluorosis can occur. A regional dental fluorosis is a typical endemic fluorosis chronic disease the most common and prominent early symptoms, here we take a look at the introduction of experts:

1. Clinical manifestations of dental fluorosis is characterized by the eruption of the enamel in the same period have chalk color to brown patch, but also complicated with dental supplies severe enamel defects in real terms. Their often clinically mild, moderate and severe and is divided into chalk-type (mild), color type (moderate) and defect type (severe) three types;

2. Poor tolerance of friction, but strong resistance to etching;

3. Patients with severe chronic fluorosis, may have proliferative changes of bone, periosteum, ligaments, etc. can be calcified, and resulting in the waist, legs and joints symptoms. Acute poisoning symptoms are nausea, vomiting and diarrhea. As the combination of calcium and fluoride to form insoluble calcium fluoride, causing muscle spasms, breathing difficulties and collapse, resulting in death;

4. More common in permanent teeth, are rarely in deciduous teeth, the degree is also lighter. This is due to the occurrence of teeth and milk, respectively, in the infant stage Comprehensive Interpretation of dental fluorosis embryo, and placenta barrier for fluorine has some role. Therefore, dental fluorosis are generally found in permanent teeth, but if excessive fluoride intake, exceeding its screening function of the limit, also irregular teeth on the surface now.
