目的：研究一种新型钛合金在模拟口腔环境中的表面色泽的改变，为口腔内存在钛合金种植体或戴用钛合金义齿的患者给予临床指导。方法将制备好的钛合金试件随机分为8组。每组试件于处理前以及处理后，分别测量色彩值CIE L*a*b*，应用SPSS 统计软件分析所得结果。结果刷洗组试件相对不刷洗组试件表面色泽改变增大，具有统计学意义（P＜0．01）；使用含氟牙膏组的表面色泽改变略大于不含氟牙膏组，但两组改变值无统计学意义（P ＞0．05）；通过对pH 值和氟离子浓度两个因素的交互效应的统计学分析，提示两因素之间存在交互作用（P ＜0．05），具有统计学意义。结论近β钛合金的腐蚀程度主要与是否刷洗，以及模拟口腔环境中氟离子浓度和pH 值的交互作用有关。

Objective To study the variation of the surface color of a new type of titanium alloy in simulated oral environment sur-face,and to provide clinical guidance for patients who have received titanium implant therapy or wear denture. Methods Titanium chips were prepared and divided into eight groups randomly. CIE L*a*b* of each specimen was examined by SPSS software before and after treatment. Results The surface color of the brushing group was more evident than that of the non-brushing group (P <0. 01). The surface color change of Fluoride-containing toothpaste group was more than that of non-fluoride-containing toothpaste group, but the change was not statistically significant(P > 0. 05). pH value had a significant interactive effect with fluoride ionic concentration (P < 0. 05). Conclusions pH,fluoride ionic concentration,and tooth brushing all have an effect on the degree of corrosion.
