Hydrocal, Calcium Hydroxide Paste for Pulp Capping and Cavity Liner

Clinical Overview

Hydrocal™ is a two-part, radiopaque calcium hydroxide paste indicated for direct and indirect pulp capping as well as deep cavity lining. It self‑sets into a rigid barrier that’s compatible with resin and amalgam restorations while supporting pulp healing through its high‑pH antibacterial effect.

Key Benefits

• Versatile use: effective for both direct and indirect pulp capping, and as a deep cavity liner.
• Self-setting & radiopaque: forms a solid barrier visible on radiographs for quality control.
• Reliable consistency: tube‑to‑tube delivery ensures consistent mix and easy handling.
• Material compatibility: safe under resin/composite and withstands amalgam condensation.
• Antibacterial & pH-driven healing: the high pH of calcium hydroxide supports dentin bridge formation and infection control.

Kit Contents

• 13 g Base paste (tube)
• 11 g Catalyst paste (tube)

Working & Setting Times

• Working time: quick mix upon combination.
• Set time: approximately 2–3 minutes intra-orally, ambient moisture accelerates cure.

Indications

• Direct pulp capping in pulp exposure cases
• Indirect pulp capping in deep carious preparations
• Deep cavity liner under composite, amalgam, or glass ionomer

Instructions for Use

1. Express equal lengths of base and catalyst onto a mixing pad.
2. Blend thoroughly (≈10 s) to a uniform consistency.
3. Place a thin layer over the pulp or dentin surface.
4. Allow material to set (≈2–3 min); maintain isolation.
5. Proceed with final restoration—compatible with resin/composite or amalgam.

Summary

Hydrocal™ 9005 offers a dependable, dual-paste calcium hydroxide liner that supports pulp healing, provides a radiopaque protective barrier, and integrates seamlessly under restorative materials. Its fast set and versatile application make it a valuable addition to restorative protocols.
