FLUORIDE TOXICITY, FLUOROSIS
 
Description    The major sources of toxic fluorides in domestic animals are releases into the atmosphere from industrial operations that settle on vegetation. Pitting and mottling of the permanent teeth and roughening of the periosteal surface are the major signs of Chronic Fluorosis. Bony swellings start on the limbs and also affect the mandible and ribs. Although Chronic Fluorosis is more common, Acute Fluoride Toxicity has been reported, with signs involving primarily the renal, gastrointestinal, nervous, and cardiovascular systems.
