Abstract

The present study was performed to evaluate the effect of tetracycline - HCl on the change of implant surface microstructure according to application time. Implants with pure titanium machined surface and titanium plasma-sprayed surface were utilized. Implant surface was rubbed with 50mg/ml tetracycline - HCl solution for 1 min., 1½ min., 2 min., 2½ min. and 3min. respectively in the test group and with saline for 1 min. in the control group. Then, the specimens were processed for scanning electron microscopic observation.
The following results were obtained.
1. Pure titanium machined surfaces conditioned with saline for 1 min., showed a few shallow grooves and ridges and were less irregular.
2. Pure titanium machined surfaces conditioned with 50mg/ml tetracycline - HCl solution showed more irregular and corrosive surfaces compared to the control group irrespective of the application time of tetracycline - HCl solution.
3. Titanium plasma-sprayed surfaces conditioned with saline for 1 min., were deposited with round or amorphous particles and showed round or irregular pores that can be connected to each other.
4. The irregularity of titanium plasma-sprayed surfaces conditioned with 50mg/ml tetracycline - HCl solution was lessened and the flattened areas were wider relative to the application time of tetracycline - HCl solution.
5. Titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution for 1 min. and 1½ min. were very similar to that of the control group, but the surfaces conditioned for 2 min., 2½ min. and 3 min. were changed.
In conclusion, pure titanium machined surfaces were changed irrespective of the application time of tetracycline - HCl solution. And titanium plasma-sprayed surfaces conditioned with tetracycline - HCl solution began to be changed from 1½ min. This results will be applicable to the regenerative procedures for peri-implantitis treatment.
