Abstract

The present study was performed to evaluate the effects of Tetracycline-HCl on the microstructure change of SLA implant surface according to application time. In the Tetracycline-HCl group, 6 implants were rubbed with sponges soaked 50mg/ml Tetracycline-HCl solution for 0.5min., 1min., 1.5min., 2min., 2.5min. and 3min. In the saline group, another 6 implants conditioned with sponges soaked saline using same methods. One implant wasn't conditioned anything. Then, the changes of surface roughness values were evaluated by optical interferometer & specimens were processed for scanning electron microscopic observation. The results of this study were as follows: 1. In both Tetracycline-HCl group & saline group, there are no significant differences between surface roughness values before & after surface detoxification. And in scanning electron microscopic observation, there are slightl9y changes of implant surface structures but this changes were not significant by comparison with no treatment implant surface. 2. In the changes of surface roughness values & the scanning electron microscopic observation, there were no significant differences between saline & Tetracycline-HCl groups. In conclusion, the detoxification with 50mg/ml Tetracycline-HCl within 3 minutes can be applied for treatment of peri-implantitis in SLA surface implants, without surface microstructure changes.
