Photoacoustic and electron microscopic studies of reminerlized artificially carious enamel and dentin

Electrical, photoluminescence and optical investigation of ZnO nanoparticles sintered at different temperatures

“…It is accepted that the evaluation of optical constants of ZnO has significant importance in optoelectronic and optical applications such as filters, modulators, solar cells, photodiode, switches, etc. [29][30][31][32]. Therefore, it is necessary to get some information on its optical absorption, especially when sintered at different temperatures.…”

Photothermal Radiometry and Diffuse Reflectance Analysis of Thermally Treated Bones

“…Additionally, it has been shown that the thermal diffusivity of human enamel is higher than in bones, a result that should be expected taking into account that enamel is a ceramic-like HA material [34,35]. In contrast, in the case of human dentin, having a high porosity, lower values around 2.3 × 10 −3 cm 2 ·s −1 have been reported [34][35][36][37]. These results indicate that the microstructure and composition are key factors in thermal diffusion; however, the detailed process of heat transport in non-homogenous materials and its effect on the macroscopic thermal properties is a subject that continues to be developed [38].…”

In vitro thermal diffusivity measurements as aging process study in human tooth hard tissues

“…This is probably due to the real stage of protein consolidation in the collagen. El-Brololossy et al 38 observed an increase of the values of thermal diffusivity of reminerlized artificially carious enamel and dentin. The largest values were for the samples treated with Zeolite followed by bioactive glass in the form of sealing of enamel pores and plugging of dentinal tubules.…”
