“…Furthermore, dental materials and restorative teeth were analyzed with SEM-EDX before and after carbonization, demonstrating that the original elemental composition was preserved. The ability to distinguish dental materials has an important impact on the identification process [38,39]. Even in cases of bodies in which metal osteosynthesis devices have been implanted, SEM/EDX could be considered for identification purposes.…”

The application of scanning electron microscopy with energy-dispersive X-ray analysis (SEM/EDX) to the anthropological field has begun to open up wide-ranging perspectives of evaluation and investigation of great interest from various points of view, including the forensic one. Indeed, when bones are directly affected by penetrating detrimental means, they become valuable substrates on which to perform SEM/EDX analysis for forensic purposes. Moreover, on partially or completely skeletonized corpses, anthropologists take over or work alongside the medical examiner and their contribution plays a major role. In addition, SEM/EDX analysis may also prove useful in pursuing the identification of a victim. For these reasons, anthropologists need to be increasingly aware of the huge potential of this technique. However, it requires special precautions in order to provide appropriate and reliable results. Therefore, we present the proper approach to bone tissue for SEM/EDX analysis, reporting some of its main applications in the anthropological field.

“…For example, the effects of high temperature are observed on different restorative dental materials by detecting changes in their microstructural and elemental composition and using X-ray spectroscopy to determine the content of trace elements. The ability to distinguish dental materials by elemental analyses has had an important impact on the identification process [ 140 , 141 ].…”

The presented work focuses on the application of spectroscopic methods, such as Infrared Spectroscopy (IR), Fourier Transform Infrared Spectroscopy (FT-IR), Raman spectroscopy, Ultraviolet and Visible Spectroscopy (UV-Vis), X-ray spectroscopy, and Mass Spectrometry (MS), which are widely employed in the investigation of the surface properties of dental materials. Examples of the research of materials used as tooth fillings, surface preparation in dental prosthetics, cavity preparation methods and fractographic studies of dental implants are also presented. The cited studies show that the above techniques can be valuable tools as they are expanding the research capabilities of materials used in dentistry.

“…Due to interaction between incident electrons and the slices, various types of signals may emit from irradiated tissues such as secondary electrons (SE), backscattered electrons (BSE), Auger electrons, continuous and characteristics X-rays, and other photons of different energies [18]. These signals are detected by suitable detectors available in SEM such as Everhart-Thornley detector (ETD) is used to detect SE [19], BSE using a retractable circular BSE detector (CBS) [20], and X-rays signal by energy dispersive spectrometer (EDS) detector [21]. 3D highly magnifying image form on the computer by connecting the signal detectors through the optical fiber.…”

Laser-induced breakdown spectroscopy (LIBS) analysis of human dental tissues: enamel and dentine, performed by utilizing Nd: YAG laser (𝜆=1064 𝑛𝑚, 𝜏=6 𝑛𝑠, 𝐸=50 𝑚𝐽) to investigate threshold ablation of laser energy density. Quantitative results based on the experiment provide us with threshold ablation value of laser energy density for calcium (Ca) ablation in enamel and dentine tissues. The computed threshold laser energy density for Ca ablation in dentin tissue is 0.38 J/cm2, which is significantly lower than the threshold in the enamel, which is 1.41 J/cm2. Scanning electron microscopic (SEM) examination of dental tissues determines that the dentin surface contains pores, voids, and bubbles that make it easy to ablate at low laser energy density, while enamel has a closely packed smear layer structure that is difficult to ablate, requiring high energy densities. These findings are helpful in the field of laser dentistry, where lasers are widely used for dental treatment.
