Abstract
Aim: The present study aimed to measure the concentration of lead in various indigenous
preparations of tooth powders available and used locally in and around Udaipur, Rajasthan, India.
Materials and Methods: Seven different brands of tooth powders manufactured and/or marketed
locally were obtained from stores all over Udaipur city. Some home‑made powders commonly
used for cleaning teeth were also collected. The tooth powders were analyzed for lead content
by atomic absorption spectrophotometry.
Results: All tooth powders tested were found to contain high levels of lead ranging from 21
ppm to 82 ppm, above the maximum permissible level of 20 ppm prescribed by the Bureau of
Indian Standards.
Conclusion: Indigenous tooth powders contain high levels of lead and thus may be a source of
lead poisoning that is often overlooked.
