Seal development and composition at amalgam-ceramic interfaces after NaC1 and Na2S storage: 17; 53-54https://hdl.handle.net/10539/32701Chlorine and sulphur -.have been found in the marginal seal of some tooth-amalgam interfaces . Although the role of Cl in the sealing process is relatively well established the role of S remains more obscure. The purpose of the present study was to compare the sealing properties and elemental composition of the seal formed at the interface of amalgams placed in ceramic cavities and stored in either a 10% NaCl or 10% Na2S aqueous solution. This investigation undertaken in a simple controlled environment, devoid of complex oral influences, would clarify the role that these two elements play in the sealing process at amalgam-tooth interfaces within the mouth.enDental AmalgamSodium ChlorideNac1Sodium bisulfideNa2SArticle
