The Investigation of Thermoluminescence Properties of Tooth Enamel

Öz

In this study; Thermoluminescence(TL) properties of tooth enamel which was obtained from healh teeth in the Faculty of Dentistry Aegean University. The tooth enamel was exposed to X-ray and TL spectra were taken with different heating rates (β) (2-10^oC/s). It was observed that there is a broad TL peak approximately at 210 ^oC for tooth enamel in the range of 50-400 ^oC. The dependence of heating rate and exposed X-ray dose (dose response) of the 210 ^oC peak were investigated, as well as kinetic parameters were calculated using peak shape and heating rate methods for tooth enamel.

Diş Minesinin Termolüninesans Özelliklerinin İncelenmesi

Öz

Bu çalışmada, Ege Üniversitesi Diş Hekimliği Fakültesi’nden alınan sağlıklı diş minelerinin termolüminesans (TL) özellikleri incelenmiştir. Diş minesi X ışınları ile uyarılarak farklı ısıtma hızlarında (β) (210oC/s) TL spektrumları alınmıştır. 50-400 oC aralığında diş minesi için yaklaşık 210 oC’ de geniş bir TL piki olduğu gözlenmiştir. 210 oC’ deki pikin ısıtma hızı ve X ışını dozuna bağlılığı (doz yanıt) incelenmiş, aynı zamanda pik şekli ve ısıtma hızı metodları kullanılarak diş minesi için kinetik parametreler hesaplanmıştır

Anahtar Kelimeler
