Abstract
Some physical properties of the luting cements, zinc phosphate cement, polycarboxylate cement, glass ionomer cement currently on market were examined in relation to various powder/liquid ratio, and for their fulfilment of Japanese Industrial Standards (JIS) T-6602 for dental zinc phosphate cement and American Dental Association Specification No. 8 for zinc phosphate cement. 1) Some physical properties of zinc phosphate cement were similar to traditional reports. 2) Although film thickness of polycarboxylate cement was smaller, other physical properties were similar to traditional reports. 3) Altghough film thickness and solubility of Fuji ionomer Type I and Keatc-cem were smaller than previously reported, other physical properties and physical properties of HY-BOND Glasionomer-c were similar to traditional reports.
