Ms. Hillary Clinton Less than Honest About Benghazi Threatening Security

“Yesterday’s lawyer-lingo evasions don’t matter any more, because it was all B.S. anyway. When inspectors general discovered hard proof of then-classified material flowing through ClintonMail.com, they referred the matter to the Justice Department… and warned that future public releases of Clinton’s email could be peppered with enough secret information to threaten national security.” click here for article.

Association of Urine Fluoride with Dental Fluorosis; Mexico

Jarquín-Yañez L, de Jesús Mejía-Saavedra J, Molina-Frechero N, Gaona E, Rocha-Amador DO, López-Guzmán OD, Bologna-Molina R. Association between urine fluoride and dental fluorosis as a toxicity factor in a rural community in the state of San Luis Potosi. TheScientificWorldJournal. 2015;2015:647184. doi: 10.1155/2015/647184.

OBJECTIVE: The aim of this study is to investigate urine fluoride concentration as a toxicity factor in a rural community in the state of San Luis Potosi, Mexico.

MATERIALS AND METHODS: A sample of 111 children exposed to high concentrations of fluoride in drinking water (4.13 mg/L) was evaluated. Fluoride exposure was determined by measuring urine fluoride concentration using the potentiometric method with an ion selective electrode. The diagnosis of dental fluorosis was performed by clinical examination, and the severity of damage was determined using Dean’s index and the Thylstrup-Fejerskov (TF) index.

RESULTS: The range of exposure in the study population, evaluated through the fluoride content in urine, was 1.1 to 5.9 mg/L, with a mean of 3.14±1.09 mg/L. Dental fluorosis was present in all subjects, of which 95% had severe cases. Higher urine fluoride levels and greater degrees of severity occurred in older children.

CONCLUSIONS: The results show that dental fluorosis was determined by the presence of fluoride exposure finding a high positive correlation between the severity of fluorosis and urine fluoride concentration and the years of exposure suggested a cumulative effect.
