Thermoluminescence measurements of in-vitro and in-vivo aged porcelain

Analysis of thermoluminescence characteristics of a lithium disilicate glass ceramic using a nonlinear autoregressive with exogenous input model

“…Dental ceramic used in this study [IPS e.max® (LS2)] was obtained from a dental market company (Ivoclar Vivadent TR Ceramic). Lithium disilicate ceramic was also studied . Based on the XRF results, the chemical composition of the dental ceramic sample was SiO 2 (57.0–80.0%), MgO (0.0–5.0%), Al 2 O 3 (0.0–5.0%), P 2 O 5 (0.0–11.0%), ZrO 2 (0.0–8.0%), ZnO (0.0–8.0%), Li 2 O (11.0–19.0%), K 2 O (0.0–13.0%), colouring oxides (0.0–8.0%) and pigments (0–2%).…”

“…Some authors have proposed a system of developing SiO 2 –Li 2 O crystals in glass‐phase P 2 O 5 ‐added lithium disilicate (Li 2 Si 2 O 5 ) crystals . The chemical properties of lithium disilicate glass ceramic have been described previously and these are still in use . A key study on TL dosimetry was performed previously, in which dental restorative porcelain was investigated as a TL dosimeter to predict high doses following radiation accidents and in which the use of optically stimulated luminescence (OSL) and TL of dental ceramic for retrospective dosimetry was underlined.…”

Assessment of structural and thermoluminescence characteristics of porcelain used as an electrical insulator

“…5 When the literature is examined, it becomes apparent that porcelain is typically employed for accident dosimetry, retrospective dosimetry, or dating. [6][7][8][9][10][11][12][13][14][15][16] Ancient porcelain samples are frequently TL-dated using the pre-dose effect 110 • C TL peak of quartz, 6 a significant porcelain constituent. Pre-dose measurements of the 110 • C and/or 230 • C TL peaks, and additive dose measurement of 230 • C TL peak are common techniques applied using porcelain for retrospective dosimetry.…”

“…In their study, they determined that 230 • C TL emission at 620 nm is potentially useful for retrospective dosimetry of radiological events over the past few decades. Furthermore, Sfampa et al 7 made a valuable contribution by evaluating newly created and in vitro aged porcelain samples, and the measurements were also used on in vivo aged samples that were taken from patients. All of the samples, they noted, have at least one peak that is noticeable for dosimetric purposes.…”

Adsorption effect of Zn+2 and Co+2 on the antibacterial properties of SiC‐porcelain ceramics

“…7 Multilayered porcelain coated metallic implants have been fabricated in several works which resembles similar optical properties to that of human tooth. 8,9 In a recent work, 10 Sfampa et al have investigated the thermoluminescence properties of aged porcelain, which might be used in accidental personal dosimeter.…”
