[Non-skeletal forms of fluorosis].

Concepts of nonskeletal forms of fluorosis are set forth in the light of the author's own investigations and reports in the available literature. Descriptions of pathology of the central nervous system, skeletal musculature, stomach, liver, kidney, cardiovascular system, retina, and the skin are presented. The evidences obtained indicate that disturbances in soft tissues in chronic intoxication with fluorine develop early, usually long before the onset of typical changes in teeth and skeletal bones; these changes characterize the preskeletal phase of fluorosis.

Relationship of cheek tooth abrasion to fluoride-induced permanent incisor lesions in livestock.

Teeth from cattle, sheep, and horses that ingested various fluoride intakes and teeth from field studies of these species plus deer, elk, and bison were examined for abnormalities. Approximately 99,000 animals in 322 herds were examined for fluorosis. From field studies, 988 cattle of various ages and with different degrees of dental fluorosis were slaughtered and necropsied. The severity of fluoride-induced mottling, hypoplasia, and abnormal abrasion of paired permanent incisor teeth was correlated with abrasion of premolar and molar (cheek) teeth that form and mineralize at approximately the same age. Severe irregular wear of cheek teeth impaired mastication and resulted in poor utilization of feed and unthriftiness. Excessive amounts of fluoride during tooth formation and mineralization induce characteristic dental changes. Offspring from the fluoride-affected animals did not have discernible fluoride-induced lesions in the deciduous teeth.

Suicide by exposure to sulfuryl fluoride.

The insecticide fumigant, sulfuryl fluoride, was used as an instrument of self destruction in at least two of the three fatal exposures detailed in this report. The autopsy findings, while nonspecific, have a confirmatory value. Toxicologic analysis should include a plasma and a urine fluoride level, since the toxic effects of exposure are probably related to this ion. Concentrations of fluoride in our cases were: 50.42 mg/L (Case 1) and 20 mg/L (Case 3). However, the values must be interpreted in light of all known information as a result of the paucity of reported cases of fatal sulfuryl fluoride exposures. The cases described provide a model for the investigation of tent fumigation deaths. Proper investigation of fumigant deaths requires knowledge of the insecticide, the fumigation procedure, and the implementation of warning devices. Guidelines are offered along with a procedural checklist for the investigation of tent fumigation deaths.

Experimental fluorosis in sheep: alleviating effects of aluminum.

Five groups of 4 sheep were given for 33 mo a daily oral dose of 0, 1.9 or 4.7 mg fluoride (F)/kg body weight with or without 13.5 mg aluminum (Al)/kg. In all treated animals the general health status was disturbed and osteo-dental symptoms appeared while F levels were increased in teeth, bones and organs. In sheep given the higher F dose, pathologic lesions were observed in kidney and liver. Most disturbances were dose-related and alleviated by simultaneous administration of aluminum sulfate, mainly for the lower F dose.
