Adhesion and Colonisation of Microorganisms on Porous TiO₂ and TiO₂-Silver Biomaterials

Bone graft transplantation is one of the most common transplants in the world and there has been a significant increase in the use of biomaterials in this sector. Bone substitutes are widely used in traumatology, orthopaedics, maxillofacial surgery and dentistry. The culturing method was used to determine microorganism ability to attach and form biofilms on originally synthesised porous TiO₂ and TiO₂Ag ceramics. The aim of this study was to determine and compare the intensity of adhesion and colonisation of Staphylococcus epidermidis, Pseudomonas aeruginosa and Candida albicans on TiO₂ and TiO₂Ag ceramics. The lowest adhesion and colonisation were on TiO₂Ag samples for S. epidermidis and P. aeruginosa.No C. albicans adhesion and colonisation differences were found on TiO₂ and TiO₂Ag ceramic samples.
