摘要/Abstract

摘要： 目的：研究不同种类、颜色与厚度玻璃陶瓷修复体对口腔常用光固化灯的透射玻璃陶瓷后透射光光学性能的改变。方法：用CAD/CAM技术制作二硅酸锂基玻璃陶瓷和白榴石增强型玻璃陶瓷圆片试件,每种玻璃陶瓷选择颜色为A2和A3,共分为4组。每组制作厚度为0.5~4.0mm的圆片共8个,总计32个。收集2台全新LED光固化灯,用光谱辐照度计和光功率计（积分球标定精度）测量2台光固化灯3种功率模式下的中心波长和光强,以及透射玻璃陶瓷圆片后透射光的中心波长和光强。采用SPSS 25.0软件包对数据进行统计学分析。结果：不同光固化灯功率模式、玻璃陶瓷不同类型、颜色的透射光中心波长有显著差异（P<0.05）;不同光固化灯功率模式、玻璃陶瓷不同类型、颜色、厚度的透射光光强有差异（P<0.05）。结论：光固化灯的功率模式,玻璃陶瓷的类型和颜色对透射光的中心波长有影响,玻璃陶瓷的厚度对透射光的中心波长无影响。光固化灯的功率模式,玻璃陶瓷的类型、颜色、厚度对透射光的光强有影响;其中,玻璃陶瓷厚度对透射光的光强衰减影响最显著。

Abstract: PURPOSE: To study the optical properties of two common dental light curing units and the optical properties of the transmitted light after transmitting glass ceramics. METHODS: Two types of glass-ceramic disc named IPS e.max CAD and IPS Empress CAD were produced by CAD/CAM technology, and the colors of A2 and A3 were chosen for each type of glass ceramic, then divided into 4 groups. Eight discs were made 0.5 mm to 4.0 mm thick in each group, the total number was 32. Spectra irradiance meter and power meter were used to measure the central wavelengths and irradiance of 3 power modes of 2 new LED light curing units before and after transmitting glass-ceramic discs. Statistical analysis was performed using SPSS 25.0 software package. RESULTS: Under different power modes of light curing units, different types and colors of glass ceramics, the central wavelengths of transmitted light were significantly different (P<; 0.05). Under different power modes of light curing units, different types, colors and thicknesses of glass ceramics, the irradiance of transmitted light was significantly different (P<; 0.05). CONCLUSIONS: The power mode of light curing unit, the type and color of the glass ceramic have influence on the central wavelength of the transmitted light, but the thickness of the glass ceramic has no influence on the central wavelength of the transmitted light. The power mode of the light curing unit, the type, color, and thickness of the glass ceramic have influence on the irradiance of the transmitted light, in which glass ceramic thickness has the most significant effect on the attenuation of the irradiance of the transmitted light.
