Histopathologic and bacterial evaluation of conventional and new copper amalgams.
In vivo pulpal responses in monkeys and in vitro bacterial inhibition studies were completed on new copper amalgams, Sybraloy, Dispersalloy, Tytin and a conventional Spheraloy amalgam. Amalgams were placed in cavities lined with ZOE and in unlined cavities. Silicate and ZOE were used as controls. A total of 165 adult monkey teeth were evaluated at 3 days, 5 and 8 weeks. At 3 days the pulpal res...

متن کاملTarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys
Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...
متن کاملSn4(OH)6Cl2 and SnO corrosion products of amalgams.
Although the corrosion characteristics of dental amalgam have been of considerable interest to dental researchers, it has been difficult to identify the products which form in vivo. This report demonstrates that Sn4(OH)6Cl2 and SnO are formed in vivo and in vitro. The Sn-Cl product is the predominant phase formed by corrosion-induced changes of the Sn8Hg phase of amalgam. It is present in conve...
متن کاملمقایسه کلینیکی تارنیش دو نوع آمالگام ایرانی با مس تراشه ای و کروی
There are two types of high-copper dental amalgams produced in Iran Cinalloy (lathe-cut particles) and Cinalux (spherical particles). Tarnish is one of the disadvantages of dental amalgam, which precedes corrosion, and in fact it means real destruction of restorative materials. The purpose of this study was to compare the extent of tarnish in Cinalux and Cinalloy amalgams. 32 patients, with at ...
