Öz: Bu çalışmada, saf ve nadir toprak elementlerinden olan Lantan (La) katkılı kadmiyum oksit (CdO) nanoparçacıkları soljel yöntemi ile sentezlendi. Katkılama farklı mol yüzdelerinde (1%, 3%, 5% ve 7%) gerçekleştirildi. Sentezlenen nanoparçacıklar FE-SEM, EDX, XRD ve FT-IR analizleri ile karakterize edildi. Farklı oranlardaki La katkılı CdO nanoparçacıkların dielektrik sabiti, dielektrik kayıp faktörü ve ac iletkenlik değerleri oda sıcaklığında frekansın bir fonksiyonu olarak empedans analizör cihazı ile belirlendi. La katkılı nanoparçacıklar sol-jel yöntemi ile başarılı bir şekilde sentezlenmiştir. Sentezlenen nanoparçacıklar küre benzeri formdadır ve La katkılı nanoparçacıkların boyutları saf CdO' ya göre daha yüksektir. Frekansın artması ile birlikte dielektrik özelliklerinde azalma olmuş ve daha yüksek frekanslarda sabit bir değere yaklaşmıştır. 1% La katkısı ile 6.87 olan dielektrik sabiti 7% La katkısı ile 28.15'e yükselmiştir. Dielektrik kayıp değerleri La katkısı ile azalma göstermiştir. 1% La katkısı ile 9.799x10 -5 S/cm olan iletkenlik değeri 7% La katkısı ile 6.110 x10 -7 S/cm olarak ölçülmüştür.

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.

“…By doping elements such as Mg, Zn, Ag, Bi, Cu, Cr, Li, Co, Se, Cd, Ta, F, Eu, B, and Ni to apatite, their osteogenic, antibacterial, and biological properties can be adjusted, and biocompatible materials with different properties can thus be formed [ 27 , 28 ]. Recently, trace amounts of these elements in natural bone have been the focus of attention.…”

“…Apatite nanoparticles can be produced by various processes, such as hydrothermal, mechanochemical precipitation, sonochemical, combustion, and sol–gel processes. The hydrothermal process has several advantages, such as simplicity, low cost, an almost homogeneous size distribution, and good crystallinity [ 27 , 31 ].…”

In the present study, the structural, morphological, and in vivo biocompatibility of un-doped and boron (B)-doped strontium apatite (SrAp) nanoparticles were investigated. Biomaterials were fabricated using the hydrothermal process. The structural and morphological characterizations of the fabricated nanoparticles were performed by XRD, FT-IR, FE-SEM, and EDX. Their biocompatibility was investigated by placing them in defects in rat tibiae in vivo. The un-doped and B-doped SrAp nanoparticles were successfully fabricated. The produced nanoparticles were in the shape of nano-rods, and the dimensions of the nano-rods decreased as the B ratio increased. It was observed that the structural and morphological properties of strontium apatite nanoparticles were affected by the contribution of B. A stoichiometric Sr/P ratio of 1.67 was reached in the 5% B-doped sample (1.68). The average crystallite sizes were 34.94 nm, 39.70 nm, 44.93 nm, and 48.23 nm in un-doped, 1% B-doped, 5% B-doped, and 10% B-doped samples, respectively. The results of the in vivo experiment revealed that the new bone formation and osteoblast density were higher in the groups with SrAp nanoparticles doped with different concentrations of B than in the control group, in which the open defects were untreated. It was observed that this biocompatibility and the new bone formation were especially elevated in the B groups, which added high levels of strontium were added. The osteoblast density was higher in the group in which the strontium element was placed in the opened bone defect compared with the control group. However, although new bone formation was slightly higher in the strontium group than in the control group, the difference was not statistically significant. Furthermore, the strontium group had the highest amount of fibrotic tissue formation. The produced nanoparticles can be used in dental and orthopedic applications as biomaterials.
