Abstract / Excerpt:

Potentiometric stipping analysis (PSA) was applied for the determination of lead and cadmium leaching from dental prosthetic materials and teeth. The soluble lead content in finished dental implants was found to be much lower than that of the individual compo-nents used for their preparation. Cadmium was not detected in dental implants and materials under the defined conditions. The soluble lead and cadmium content of teeth was slightly lower than the lead and cadmium content in whole teeth (w/w) reported by other research-ers, except in the case of a tooth with removed amalgam filling. The results of this work sug-gest that PSA may be a good method for lead and cadmium leaching studies for investiga-tion of the biocompatibility of dental prosthetic materials.
