Abstract / Excerpt:

The overwhelming majority of all root canal fillings in Sweden today are made with gutta-percha. A
number of different gutta-percha brands contains 0,6-0,7% cadmium, probably due to cadmium-based
color pigment. Cadmium-pigments are prohibited in Sweden since 1982. In a special regulation the
Naturvårdsverket has made an exception for dental materials. In this kind of endodontic therapy based on gutta-percha, chloroform is used both as an ingredient in a so called sealer and as a solvent for the gutta-percha itself. No drugs sold in Sweden contains chloroform. In the USA the use of chloroform is
prohibited in both drugs and cosmetics due to its canceroginity.
