摘要
目的:寻求全唾液的检测法,探讨唾液与错固定矫治牙面脱矿的关系,为脱矿风险的预测提供参考。方法:选取固定矫治后脱矿与未脱矿患者各36例(12～16岁,已矫治1～1.5a),通过傅立叶红外检测方法检测唾液样本,采用SPSS13.0软件包进行Fisher判别分析。结果:错固定矫治牙面脱矿与未脱矿患者的傅立叶红外检测光谱存在一定差异,并获得判别函数。结论:在青少年,傅立叶红外检测可作为检测唾液的重要手段。判别函数可作为错固定矫治后牙面发生脱矿的风险参考指数。
PURPOSE： To find a method for saliva analysis, and to investigate the relation between saliva and the enamel decalcification in orthodontic treatment, and to predict the risk of enamel decalcification. METHODS： The saliva samples came from 72 patients who were 12 to 16 years old （36 patients with enamel decalcification, 36 without enamel decalcification）. Fourier transforms infrared spectrometry was used to detect their saliva. The spectrum was analyzed by Fisher＇s discriminatory analysis using SPSS 13.0 software package. RESULTS： There was difference in saliva between patients with enamel decalcification and patients without enamel decalcification by Fourier transform infrared spectra. Discriminate function was obtained. CONCLUSIONS： In the teenagers, Fourier transforms infrared spectrometry is an important tool for saliva analysis. Discriminate function as a risk index of enamel decalcification could be used for fixed orthodontic treatment. Supported by Natural Science Foundation of Shanxi Province （Grant No.2004C275）.
