Dental fluorosis is a dental pathology caused by excessive ingestion of fluoride during the first years of life. Excess of fluoride will thus disrupt the normal formation of enamel crystals during amelogenesis and lead to the formation of an often unsightly porous enamel. The degree of severity of fluorosis can be established precisely using different classifications and depends on the ingested dose, the frequency of ingestion, the age of the subject and individual variability. The reason for consultation of patients with fluorosis is mainly aesthetic. The choice of treatment was based on the stage of fluorosis. There are currently very conservative therapies such as whitening or micro- abrasion, which can effectively treat mild or even moderate fluorosis. Treatment with bonded ceramic veneers or full-coverage prostheses is only indicated for cases of moderate and severe fluorosis because of their aesthetic interest and their mechanical and biological properties. It will therefore be appropriate for the partitionner to make a precise diagnosis and to choose the best suited therapy to his patient.Our papier will present and discuss 3 clinical cases about the managment of dental fluorosis.
