Key specifications

Material type: Radiopaque, self‑curing calcium hydroxide cavity liner (two‑component base and catalyst system).

Indications: Direct pulp capping on exposed vital pulp; indirect pulp capping on deep dentin; protective liner/base under composites, amalgam, cements and varnishes.

Setting characteristics: Paste‑to‑paste mix with short mixing time (around 10 seconds), working time about 2 minutes and intraoral setting in roughly 2.5–3.5 minutes.

Physical properties: High compressive strength, low solubility and hard set to withstand amalgam condensation and support overlying materials.

Radiopacity: Clearly visible on radiographs to distinguish liner from dentin and caries.

Pulp response: Alkaline pH and calcium hydroxide content that help protect pulp tissue and promote tertiary dentin formation.

Shades: Commonly supplied in Ivory and Dentin‑like shades for better esthetics under translucent restorations (adjust to the shade you stock).

Packaging: Typically 1 base tube (about 11–13 g), 1 catalyst tube (about 11 g) and a mixing pad (confirm exact content for your SKU).

Dycal Liner uses a base and catalyst paste system that mixes easily to a smooth consistency and sets quickly into a hard, radiopaque layer on dentin or exposed vital pulp. The calcium hydroxide content creates an alkaline environment that stimulates secondary dentin formation while providing a thermal and chemical barrier beneath restorative materials. Its formulation does not interfere with the polymerization of acrylic and composite materials, so clinicians can place permanent restorations or bases immediately after the liner sets.
