摘要: The aim of this paper is to compare the fluoride-releasing and mechanical properties an experimental luting glass ionomer cement, which has a modified composition commercial cement. powder was obtained by sol-gel process then, it used prepare cements. cement pastes, such as setting time working time, microhardness diametral tensile strength were determined. Fluoride release from GICs evaluated at intervals 1, 7, 14, 21 28 days in deionized water. Atomic force microscopy (AFM) analyses showed that surface cements more homogeneous than GICs. measure liberation fluoride two influenced ratio powder:liquid chemical precursor powders. Experimental released less However, constant during analyzed period. Thus, results study indicated niobium can lead formation polysalt matrix with good properties. In other words, we say offered considerable promise for exploitation dental field.
