Title An evaluation of non-precious alloys for use with porcelain veneers - Part II: Industrial safety and biocompatibility.
Bibliographic information Oct. 1973, Vol.30, No.4, Part 1, p.432-441. Illus. 9 ref.
Abstract An air-sampling survey was conducted to determine whether or not the use of beryllium-containing non-precious alloys constitutes a dental occupational hazard. The biocompatibility of certain non-precious alloys was also assessed by means of animal implants. Results show that with proper local exhaust ventilation, non-precious beryllium containing alloys may be used safely in dental laboratories. The biocompatibility study demonstrates that several non-precious alloys produce a mild histological response not significantly different from that produced by the control gold-based alloy and less than that produced by zinc oxide and engenol cement and silicate cement.
