Dental Materials — Key differences for NEET MDS
Addition silicone PVS = most accurate no byproduct. Condensation silicone = releases alcohol byproduct = shrinkage. Polysulfide = longest setting time messiest = lead dioxide accelerator. Polyether = stiffest most hydrophilic = initial rigidity. Alginate = irreversible hydrocolloid = snap set. Agar = reversible hydrocolloid = high detail low strength. Impression plaster = most rigid.

Resin cement = best with all-ceramic restorations. ZOE = most biocompatible least irritating weakest cement. Polycarboxylate = chemical adhesion mild pulp response. Zinc silicophosphate = combined ZPC and silicate properties.
