A study on the dosimetric properties of polycarboxylate cement used in dental treatments

Zinc Polycarboxylate cement is one of the few dental materials that demonstrate true adhesion to tooth structure. The powder is primarily zinc oxide, and the liquid is polyacrylic acid or a copolymer of that acid. In this study, the dosimetry properties of Zinc Polycarboxylate cement using thermoluminescence (TL) were investigated and determined the effectiveness of its use as a good dosimeter. As a result, the sample shows a good TL properties with three main peaks found around 140 ℃, 220 ℃ and 330 ℃. It has a wide linear dose response between 144 𝐺𝑦 and 2.3 𝐾𝐺𝑦 and good reusability with eight cycles of measurement. Keywords: Thermoluminescence, Dosimetry Properties, Zinc Polycarboxylate
