Abstract

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, HA-coated surface and dual acid etched surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline-HCL solution for ½min., 1min., 1½min., 2min., and 2½min. respectively in the test group. Then, specimens were processed for scanning electron microscopic observation.
The results of this study were as follows.
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 groups.
2. In HA-coated surfaces, round particles were deposited irregularly. The roughness of surfaces conditioned with tetracycline-HCL was lessened and the cracks were increased relative to the application time.
3. The etched surfaces showed the honey comb structures. The surface conditioning with tetracycline-HCl didn't influence on its micro-morphology.
In conclusion, the detoxification with 50mg/ml tetracycline-HCl must be applied respectively with different time according to various implant surfaces.
