Description
Seal Apex Sealer is a two-component (powder + liquid) calcium hydroxide–based root canal sealer designed for use with gutta-percha during obturation. Its non-eugenol formulation reduces the risk of tissue irritation while providing antimicrobial activity and apical healing support.
Dentists mix the powder and liquid to achieve a smooth, creamy consistency for easy canal placement.
Seal Apex Sealer Composition
-
Calcium Hydroxide (Ca(OH)₂) based
-
Non-eugenol formulation
-
Powder + Liquid system
The high pH of calcium hydroxide contributes to antibacterial activity within the canal system.
Clinical Indications
Dentists use Seal Apex Sealer for:
-
Root canal obturation with gutta-percha
-
Filling accessory canals
-
Enhancing apical sealing
-
Supporting periapical healing
-
Cases requiring antimicrobial support
It complements standard obturation techniques, including lateral and vertical condensation.
Key Clinical Properties
Antimicrobial Activity
Calcium hydroxide produces a high pH environment that suppresses residual microorganisms in the root canal system.
Hard Tissue Formation
The material supports hard tissue formation and may contribute to apical repair and periapical healing.
Biocompatibility
Seal Apex Sealer demonstrates compatibility with periapical tissues and minimizes inflammatory response.
Non-Eugenol Formula
The absence of eugenol reduces the risk of irritation, allergic reactions, staining, and odor issues.
Adequate Working Time
The material provides sufficient working time for mixing, loading, and placement before setting.
Good Sealing Adaptation
It fills voids around gutta-percha cones and reduces microleakage.

-
Dispense the required amount of powder.
-
Add the recommended quantity of liquid.
-
Mix until you achieve a smooth, mayonnaise-like consistency.
-
Apply inside the canal using a lentulo spiral or suitable carrier.
-
Insert gutta-percha cones and complete obturation.
