摘要：

Among the materials applied in dentistry, porcelain is the most predominant one, as it has been used for dental restorations for decades. Towards the Thermoluminescence (TL) investigation of dental porcelain, and its capability to act as a personal accident dosimeter, the present work further examines-through a series of measurement protocols-the physical mechanisms responsible for the isothermal TL signal of its main dosimetric TL peak. Moreover, the influence of light on the TL of the same main peak is studied by means of Optically Stimulated Luminescence (OSL) measurements, while the origin of the OSL signal is further investigated. Finally, the existence of very deep traps of the material is examined and discussed via specific protocols.
