An experimental study on dosimetric and characteristic properties of bovine dentin

In this study, a bovine dentin, from a material collection which was excavated in Nevşehir–Ürgüp, Turkey, was used. This dentin sample was prepared in the laboratory using cutting, cleaning, grinding, and separating processes, respectively. The obtained dentin aliquots were irradiated with multiply...

Description
Summary:In this study, a bovine dentin, from a material collection which was excavated in Nevşehir–Ürgüp, Turkey, was used. This dentin sample was prepared in the laboratory using cutting, cleaning, grinding, and separating processes, respectively. The obtained dentin aliquots were irradiated with multiply radiation doses between 50 Gy and 2 kGy by 60 Co-gamma irradiator. The dosimetric properties and the radiation dose of this sample were determined using the electron paramagnetic resonance (EPR) method. During the measurements, the EPR spectra were recorded at four different temperatures (4 K, 50 K, 100 K, and 298 K) using X-Band ESR spectrometer. By these spectra, it was determined that the radiation-induced paramagnetic radical was occurred, and the accumulated radiation dose was calculated to be (12.404 ± 0.48) Gy. Also, this sample was analyzed in terms of microstructure and porosity using the field emission scanning electron microscopy, elemental composition using the energy-dispersive X-ray spectrometry, mineralogical composition using the X-ray diffraction, and chemical bonding using the Fourier transform infrared spectroscopy. As a result of all these measurements, it was understood that this sample had a single-phase hydroxyapatite crystal.
