Microradiographic study of bone and tooth alterations in bovine fluorosis.
Exostoses were found in the 5th rib, the cannon bone and the mandible of a 6-year-old fluorotic cow. Microradiographic alterations of lamellar bone in these skeletal items included both matrix modifications and mineralization troubles. In the incisors, the enamel was covered by a layer of cementum, and the dentine presented numerous giant tubules and accentuation of incremental lines. In the cementum, hypomineralized areas were located along the periodontal fibres.
