Two horses that consumed well water with high fluoride content exhibited clinical signs of chronic dental and skeletal fluoride toxicosis and were later euthanized and autopsied. Both horses had degenerative disease of multiple joints and multiple dental defects. Elevated fluoride concentrations were found in bone and tooth samples of both horses, well water, and feed. Microscopically, abnormalities were noted in bone and tooth samples, and consisted mostly of foci of cement necrosis and hypercementosis. Horses exhibiting bilateral, highly symmetrical dental and/or skeletal lesions, with chronic lameness, should be evaluated for the possible presence of fluoride toxicosis.
两匹马饮用高氟井水后出现慢性牙和骨骼氟中毒的临床症状，随后被安乐死并进行了解剖。两匹马都有关节退行性疾病和多处牙齿缺陷。两匹马的骨骼和牙齿样本、井水和饲料中都发现氟浓度升高。显微镜下，骨和牙齿样本存在异常，主要为牙骨质坏死和过度矿化灶。出现双侧、高度对称的牙齿和/或骨骼病变、慢性跛行的马匹，应评估是否存在氟中毒。
