title: Application of the INAA technique for elemental analysis of metallic biomaterials used in dentistry.
abstract: The sensitive nuclear analytical technique Instrumental Neutron Activation Analysis (INAA) has been applied on several types of metallic biomaterials (Heraenium CE, Ventura Nibon, Wiron 99 and Ducinox which are currently used for restoration in the dental clinics) to study its performance in elemental analysis and identify eventual limitations. The investigation has been performed by two NAA Laboratories and aimed at getting an answer to the question on how the biomaterials compositions influence the patients' health over the course of time, taking into account the EC Directive 94/27/EC recommendations concerning Ni toxicity.
