Light-activated glass polyalkenoate (ionomer) cements: the setting reaction

In situ microhardness evaluation of glass–ionomer/composite resin hybrid materials at different post‐irradiation times

“…For glass–ionomer/composite resin hybrid materials, an improvement of mechanical properties as a function of time can be verified, reflecting the continuity of the setting reaction (Wilson, 1990; Sidhu & Watson, 1995). A positive relation between microhardness levels and time can be verified (Bourke et al ., 1992; Kao et al ., 1994; Burgess et al ., 1995; Swift et al ., 1995; Kanchanavasita, Anstice & Pearson, 1998) although superficial microhardness cannot reliably detect the setting reaction that occurs in the bulk of the material (Kilpatrick, McCabe & Murray, 1994).…”

The Effect of Nanofilled Resin-Base Coating on the Mechanical and Physical Properties of Resin Composites

“…37 Any alteration in microhardness might indicate the material’s setting reaction and the uncompleted maturation of the restorative material. 38 In the present study, VHN were measured after 24 hours and 60 days of storage in DW. Therefore, the maturity of the resin composites was reached at the time of measurement, and any differences observed in VHN between study groups could be attributed to the effects of coating application and material composition.…”

Long-Term Water Balance Evaluation in Glass Ionomer Restorative Materials

“…This evaluation involved the first long-term study of selected conventional and RMGI glass ionomer restorative products, including some materials not previously reported in the scientific literature. Thermal analysis techniques have been utilized to evaluate glass ionomer cement products [21,25,[52][53][54][55] and this evaluation used a combined differential scanning calorimetry-thermogravimetric analysis technology (DSC/TGA) technology. Specimens were subjected to a 25-620 • C thermal challenge at a rate of 10 • C/min with simultaneous thermal and weight change data recorded.…”
