치주조직유도재생술 시행시 Gore-tex 차폐막에 부착되는 치주세균에 대한 미노클린첨부제의 향균력에 대한 미생물학적 연구 = Microbiological study of the antibacterial effects of locally delivered $Minocycline^R$ on the plaque accumulation on $Gore-tex^R$ membrane during the guided tissue regeneration therapy

다국어 초록 (Multilingual Abstract)

The present study was done to evaluate the antibacterial effects of $Minoclin^R$ which was localally delivered on the $Gore-tex^R$ barrier membrane in the guided tissue regeneration(GTR) therapy for treatment of human furcal defects. Beneath the membranes. the antibiotics were applied for 1 week and then changed with new one. The $Minoclin^R$ was removed out one week later. 6 weeks after the GTR therapy. No systemic antibiotics were administered except for oral mouthrinses with chlorhexidines. 2 weeks and 6 weeks following the membrane therapy, the bacterial samples were examined for periodontopathic microorganisms. The results indicated that the locally delivered $Minoclin^R$ successfully inhibited the growth of periodontopathic organisms. This results might be further applied in the subgingival plaque control regimen in the GTR procedure, especialy in patients who is contraindicated for oral administration of systemic antibiotics
