Lead health hazard in root calan filling material.

It has been stated in the recent literature that the lead content of N2 endodontic filling material poses a hazard of lead otxicity to the patient. No clinical evidence in humans was offered in support of the statements. In the studies here reported, it was determined that endodontic fillings of RC2B, A U.S. variant of the N2 material, contain, per root-canal, a quantity of lead equivalent to permissible uptake of 10-15 days. It is believed lead is generally unavailable to the blood stream, due primarily to its being chemically bound, and secondarily to the known affinity of dentin for lead. It was found that the levels of lead in the blood of nine young male patients, sampled at intervals up to 90 days following placement of RC2B endodontic fillings, were mostly nondetectable, did not exceed 9 mug/100 ml in any instance, and were all far below the accepted hazard-indicating level of 40 mug/100 ml whole blood.

Enhanced fluoride uptake by teeth through use of iontophoretic techniques.

The effects of electric currents on the uptake of fluoride ions by human teeth, in vitro were determined by measuring the change in fluoride ion concentration of the electrolyte in which teeth were subjected to the electrochemical treatment. There was an enhanced uptake when the gold electrode embedded in the tooth was polarized anodically. Evidence that the fluoride ions were taken upon by the teeth was shown by subsequent cathodic polarization of the gold electrode in a fluoride free electrolyte and by measurement of fluoride release into the solution.
