| Research Abstract |
There have been a number of reports of surface treatment of titanium to acquire osseointegration earlier. Ultraviolet (UV) lamp have attracted much attention in recent years because of promoting cellular attachment and proliferation by their radiation effect to titanium. The purpose of this study has been to compared the ability of these types UV lamp, excimer UV lamp (EX-UV) and the low-pressure Hg-UV lamp (LP-UV).Generally, when an electron at ground state has received high energy, it transits to an outer orbit having higher energy. This status is an excited status and each of elements has individual energy level. When the electron has transited back to the inner orbit having lower energy, light corresponding to the difference of energies is irradiated.It has been felt that the excimer UV lamp offers shortening radiation time to get the same effect of LP-UV. In addition we will attempt analysis of surface chemical constitution change before and after the UV radiation, and cellular responses in vitro and in vivo.
