초록
The purpose of this study was to compare the bond strength of the glass ionomer luting cements after the functional loads were applied to the crowns respectively 10 min, 30 min, 1 hr, 24 hrs later after mixing of cements. The conventional (GC Fuji I; GC Int. Co., Japan), water hardening type (Ketac Cem; ESPE, W. Germany) glass ionomer luting cement and C-dent ZPC (Confi-Dental Products Co., U.S.A.) as a control were used. The results of this study were obtained as follows: 1. In the bond strength of GC Fuji I, 24 hr-group was highest and there were no statistically significant differences among 10 min-, 30 min- and 1 hr- groups. 2. l3 the bond strength of Ketac Cem and C-dent ZPC, there was no statistically significant differences among 10 min-, 30 min-, 1 hr- and 24 hr-groups respectively. 3. Comparing the bond strength among cements in 10 min-, 30 min-groups respectively, GC Fuji I was lowest and there was no statistically significant difference between Ketac Cem and C-dent ZPC. 4. The bond strengths between GC Fuji I and Ketac Cem were not significantly different in 1 hr-, 24 hr-group. 5. The bond strengths among 3 types of cements were not significantly different in 24 hr-groups.
