The present study was performed to evaluate the effect of tetracycline-HCl on the change of implant surface microstructure according to application time. Implant with pure titanium machined surface, GBA surface and RBM surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline-HCl solution for min. 1min. min. 2min. and min. respectively in the test group. Then, specimens were processed for scanning electron microscopic observation. The results of this study were as follow. 1. Both test and control group showed a few shallow grooves and ridges in pure titanium machined surface implants. There were not significant differences between two group. 2. In GBA surfaces, control group exhibit many porous depression, and each depression were divided by strict border. Experimental group applied with tetracycline-HCl for 2min. were similar with control group. But when applied for min. surface alteration and border breakdown started, resulting enlargement of the porous depression. 3. In REM surface, control group exhibit rough, uneven surface with crater-like depression can be found. The surface alteration started when tetracycline-HCl was applied for 30sec. resulting breakdown of the crater-like depression. Depression became larger as applying time increased.
