title: [Dose and exposure reduction in endodontic radiology through the use of new filters].
abstract: In this study the authors discuss parameters which influence the emission spectrum of x-rays and criteria that have an influence on their distribution (anode current, tension), and they draw attention to the materials most frequently used for filter construction-niobium in particular. The authors conducted a clinical study to verify whether the use of a niobium filter mounted on an x-ray machine would decrease the amount of exposure to the patient and give a higher quality image as well, because of decreased radium diffusion which consequently diminishes the risk to the operators.
