Dental ceramics because of their translucency exemplify the most biologically realistic restorative materials for aesthetic rehabilitation and can be used to estimate dose accumulated as a result of a nuclear accident or attack. In this study, lithium disilicate ceramic obtained from Vivadent Ivoclar, Turkey was studied for its thermoluminescence (TL) properties. The lithium disilicate glass ceramic was irradiated with a ⁹⁰Sr–⁹⁰Y β‐source from 10 Gy to 6.9 kGy and the results read on a Harshaw 3500 reader. The TL peak of lithium disilicate ceramic showed sublinearity in the range 12 Gy to 6 kGy. The area under the TL glow curve increased by about 25% by the end of 10th measurement cycle. Fading values were also considered after irradiation. Lithium disilicate ceramic samples underwent 37% fading after 1 h and 59% fading after 1 week. In addition to the experimental study, a software‐based simulation study was also undertaken using a MATLAB system identification tool. Experimental studies are generally time consuming and some materials used for experiments are very expensive. In this study, experimental, and simulation results were compared and produced almost the same outcome with a similarity of more than 98%.

使用外部输入模型的非线性自回归分析二硅酸锂玻璃陶瓷的热致发光特性。

牙科陶瓷由于其半透明性，是进行美学修复的生物学上最现实的修复材料的典范，可用于估计由于核事故或攻击而积累的剂量。在这项研究中，研究了从土耳其Vivadent Ivoclar获得的二硅酸锂陶瓷的热致发光（TL）性能。二硅酸锂玻璃陶瓷用⁹⁰ Sr– ⁹⁰辐照Yβ源从10 Gy到6.9 kGy，并在Harshaw 3500阅读器上读取结果。二硅酸锂陶瓷的TL峰在12 Gy至6 kGy范围内表现出亚线性。到第10个测量周期结束时，TL辉光曲线下的面积增加了约25％。辐射后也考虑了褪色值。二硅酸锂陶瓷样品在1小时后褪色37％，在1周后褪色59％。除了实验研究之外，还使用MATLAB系统识别工具进行了基于软件的模拟研究。实验研究通常很耗时，并且一些用于实验的材料非常昂贵。在这项研究中，对实验和仿真结果进行了比较，得出了几乎相同的结果，相似度均超过98％。
