Migraine is basically vascular in origin, involving vasodilation and inflammation of cranial blood vessels, particularly the trigeminal vascular system. The pathophysiology involves changes in cerebral blood flow and release of vasoactive substances. MPDS is muscular, glossopharyngeal neuralgia is neurologic, and glossodynia is often idiopathic or related to local factors rather than vascular.

Zinc 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.

Adrenaline is the drug of choice in anaphylactic shock as it acts rapidly to counteract the effects of histamine by causing vasoconstriction and bronchodilation. It is administered intramuscularly to ensure quick absorption and action.
