ZrO<sub>2<\/sub> presents three types of crystalline structures at ambient pressure: the monoclinic phase (<em>m<\/em>-ZrO<sub>2<\/sub>), stable from room temperature up to 1170 \u00b0C which exhibits poor mechanical properties, the tetragonal phase (<em>t<\/em>-ZrO<sub>2<\/sub>), which is stable in the temperature range 1170-2370 \u00b0C and has good mechanical properties, and the cubic phase (<em>c<\/em>-ZrO<sub>2<\/sub>), which is stable above 2370 \u00b0C and has moderate mechanical properties [French et al, 1994; Denry &amp; Kelly, 2008]. To prevent the volume expansion during cooling, ZrO<sub>2<\/sub> can be stabilized with different oxides like MgO, CaO, Y<sub>2<\/sub>O<sub>3<\/sub>, CeO<sub>2<\/sub>, using different methods of synthesis.<\/p>\n<p style=\"text-align: justify;\">In this work, Zr<sub>2-x<\/sub>Mg<sub>x<\/sub>O<sub>2<\/sub> (x = 0.05, 0.1, 0.15, 0.2, 0.25 and 0.3) was synthesized by solid-state reaction at high temperature, followed by their <em>in vitro<\/em> characterisation. The analysis of the amount of Zr<sup>4+<\/sup> and Mg<sup>2+<\/sup> ions dissolved in the Xerostom<sup>\u00ae<\/sup> saliva substitute gel after two months exposure times, using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) technique, showed dissolution of Mg<sup>2+<\/sup>. The XRPD (X-ray powder diffraction) technique was employed to investigate the phase transformations occurring during the degradation process in Xerostom<sup>\u00ae<\/sup>. The results revealed that the <em>t<\/em>-ZrO<sub>2 <\/sub>is the predominant phase for all the prepared compositions. The coexistence of both <em>t<\/em>&#8211; and <em>m<\/em>-ZrO<sub>2<\/sub> phases on the x = 0.1 composition was evidenced. Moreover, an examination by SEM\/EDS (scanning electron microscopy\/energy dispersive X-ray spectroscopy) showed interconnected grains in the sintered ceramics and confirmed the presence of Mg, Zr, and O, with a homogenous distribution throughout the samples.<\/p>\n<p><strong>References<\/strong><\/p>\n<p>French, R.H.; Glass, S.J.; Ohuchi, F.S.; Xu, Y.-N.; Ching, W.Y.
