In this study, antibacterial chlorhexidine (CHX)-containing hydroxyapatite (HAp) was coated on titanium and investigated its characteristics. Ti-mSBF-CHX group was prepared by soaking titanium disks in the modified simulated body fluid (mSBF) mixed with CHX. Ti-mSBF group was coated using mSBF without CHX. Ti-mSBF-adCHX group was prepared by soaking Ti-mSBF specimen in CHX-containing solution. The crystallines clusters composed with nano-shaped crystallites were coated on the surface of the Ti-mSBF specimen. The ribbon-shaped crystallites were observed with the crystalline clusters on the Ti-mSBF-CHX specimen. The content of CHX chemical compositions was high in ribbon-shaped crystallites. HAp crystalline structure was dominant for all prepared specimens, and
본 연구에서는 타이타늄 상에 항균제 클로르헥시딘(chlorhexidine; CHX)이 함유된 수산화인회석을 코팅하고 그 특성을 규명하였다. CHX를 혼합한 개조된 생체유사용액(modified simulated body fluid; mSBF)에 타이타늄 디스크를 침적하여 Ti-mSBF-CHX 시편군을 준비하였다. CHX를 함유하지 않은 mSBF에 침적하여 코팅한 Ti-mSBF 시편군을 다시 CHX 용액에 침적하여 Ti-mSBF-adCHX 시편군을 준비하였다. Ti-mSBF 시편 표면에 나노 형태의 결정들로 구성된 구형의 클러스터들이 균일하게 코팅되었다. Ti-mSBF-CHX 시편에서는 이러한 클러스터들과 함께 리본형상의 결정들이 관찰되었으며, 이 결정들에서 높은 CHX 조성이 측정되었다. 두 시편 모두 HAp 결정구조가 지배적이었으며,
