Fluoride content in Pan masala, chewing tobacco, betel nuts (supari), toothpastes and tooth-powder items used and consumed in rural and urban parts of Rampur district, Uttar Pradesh by Rajesh Kumar, S.S.Yadav

Levels of fluoride content in pan masala, chewing tobacco, betel nuts, toothpastes and tooth-powder were
estimated in the rural and urban areas of Rampur district (Uttar Pradesh). These items are, generally,
ignored while calculating the total dietary intake of fluoride. An effort was also made to quantify, on the
basis of available studies, the probable human ingestion of fluoride through these substances. Increased
leaching of fluoride from some of these substances has been observed in acidic conditions in the present
study. The results can be extrapolated to acidic conditions of human stomach. The significant amount of
fluoride ingested through these items is equivalent to additional sources of fluoride.
