Thromboinflammation as bioactivity assessment of HO-alkali modified titanium surfaces.

The release of growth factors from platelets, mediated by the coagulation and the complement system, plays an important role in the bone formation around implants. This study aimed at exploring the thromboinflammatory response of HO-alkali soaked commercially pure titanium grade 2 discs exposed to whole human blood, as a way to assess the bioactivity of the discs. Commercially pure titanium grade 2 discs were modified by soaking in HO, NaOH and Ca(OH).

Antibacterial investigation of titanium-copper alloys using luminescent Staphylococcus epidermidis in a direct contact test.

Commercially pure titanium (CP-Ti), used as oral implants, is often populated by various bacterial colonies in the oral cavity. These bacteria can cause Peri-implantitis, leading to loss of bone tissue and failure of implants. With the increased awareness of antibiotic resistance, research has been directed towards alternative solutions and recent findings have indicated titanium‑copper (Ti-Cu) alloys as a promising antibacterial material.

Titanium surface modification to enhance antibacterial and bioactive properties while retaining biocompatibility.

Bacterial infections associated with metal implants are severe problems affecting a considerable amount of people with dental or orthopedic implants. This study aims to examine the antibacterial effect of a Titanium-peroxy gel layer on the modified surface of commercially pure titanium grade 2. Variations in a multi-step surface modification procedure were tested to determine the best combination that provided an antibacterial effect while enhancing bioactivity without compromising biocompatibility.

Debridement of Bacterial Biofilms with TiO/HO Solutions and Visible Light Irradiation.

Objectives: The aim of the study was to explore the debridement efficacy of different solutions of HO and rutile particles against and biofilms attached to titanium surfaces when exposed to visible light.

Materials And Methods: Titanium discs cultivated with biofilms of or were subjected for 1 min to suspensions consisting of rutile particles mixed with high (950 mM) or low (2 mM) concentrations of HO under visible light irradiation (405 nm; 2.1 mW/cm).

Organic degradation potential of a TiO/HO/UV-vis system for dental applications.

Objectives: The combination of TiO and HO under light activation constitutes a promising method for disinfection of dental prosthetics and implants, due to production of reactive oxygen species (ROS). The aim of this work was to investigate the organic degradation ability of TiO particles in combination with HO and under light activation utilizing the organic dye rhodamine B (RhB).

Methods: Five different types of TiO particles, consisting of anatase, rutile, or a mixture of these crystalline phases, were combined with HO and RhB, and subsequently exposed to UV (365nm) or visible (405nm) light at an irradiance of 2.
