Choi SH, et al. - This research aspired to evaluate whether the biological activity of the surface of titanium, when stored in an aqueous solution, in low vacuum, and under ambient conditions after ultraviolet light (UV) treatment was comparable to that of the surface immediately after UV treatment for 15 min and that after dielectric barrier discharge (DBD) plasma treatment for 15 min. Followed by wet storage, UV treatment of the titanium implants was useful for maintaining enhanced biological activity and overcoming biological aging during shelf storage.
