Effect of Excimer UV lamp radiation on titanium

已经有一些关于钛表面处理以更早获得骨结合的报道。紫外线(UV)灯通过对钛的辐射作用促进细胞的附着和增殖，近年来引起了人们的广泛关注。这项研究的目的是比较这几种类型的紫外灯，准分子紫外灯(EX-UV)和低压汞-紫外灯(LP-UV)的能力。一般来说，当一个基态的电子获得高能量时，它会跃迁到能量更高的外轨道。这种状态是一种激发状态，每个元素都有各自的能级。当电子转移回能量较低的内轨道时，与能量差对应的光被照射，人们认为准分子紫外灯缩短了辐射时间，获得了与LP-UV相同的效果。此外，我们还将尝试分析紫外线照射前后表面化学成分的变化，以及体外和体内的细胞反应。

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.
