摘要
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p H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p H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 surface,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 p H,fluoride ionic concentration,and tooth brushing all have an effect on the degree of corrosion.
