tarnish and corrosion behavior of three commercial dental amalgams namely am.1, am.2, am.3, have been investigated by utilizing in vitro tests. the corrosion and/or dissolution rate of the three dental amalgams were studied in 0.9 wt% nacl solution, artificial saliva and ringers solution. potentiodynamic polarization technique was employed to study cathodic and anodic polarization behavior, fro...

93 Abstract The findings presented here suggest that mercury poisoning from dental amalgams may play a role in the etiology of oral health disorders in multiple sclerosis (MS) patients. Comparisons between MS subjects with dental amalgams and a control group of MS subjects without amalgams found significantly fewer oral cavity symptoms per subject in the amalgam-removal group during twelve mont...

This article is part of the program described in [3]. We study the Phan amalgams and their universal completions that occur for q = 3 in rank n = 3 for the diagram A3 = D3, corresponding to SU(4, 3) ∼= Spin−(6, 3). We show that the associated geometries admit universal 9-fold coverings, by showing that the universal completion of the Phan amalgam is the central extension of SU(4, 3) by its Schu...
