The fluoride as environmental factor with influence over the dental structure.

The halogen fluoride is well distributed throughout the Earth and never occurs in a free state in Nature. Fluorine exists only in combination with other elements as fluoride compounds, which are constituents of minerals in rocks and soil. Fluoride accumulates in the hard tissues of the body and is known to play an important role in the mineralization of bones and teeth While fluoride is accepted as an effective method to prevent caries, the excessive consumption of fluoride can put bones and teeth at risk of developing fluorosi. My main objective is to identify, from the earliest stages, the abnormalities in the dental system of the children and adolescents who study in the schools of Bihor County.
