NEETMDSZinc phosphate cement is an anhydrous powder and liquid system, and its liquid (phosphoric acid) is very stable. Glass ionomer cement (GIC) liquid is polyacrylic acid, which is more prone to water loss or gain than zinc phosphate liquid. Polycarboxylate cement liquid is also polyacrylic acid, but it is typically supplied in a solution form that is highly susceptible to water evaporation when exposed to air, leading to changes in viscosity and handling properties. Therefore, polycarboxylate liquid has the highest rate of water loss, followed by GIC liquid, and then zinc phosphate liquid.

Oral PathologyMarcus Gunn phenomenon is characteristic of jaw winking syndrome, where there is synkinetic movement between the pterygoid muscles and the levator palpebrae superioris. This causes the eyelid to elevate when the jaw moves (especially with lateral jaw movements). This congenital condition involves aberrant neural connections. Marin-Amat syndrome, Horners syndrome, and Eagles syndrome do not involve this jaw-eyelid synkinesis.
