ENDOSEAL MTA is a paste-type root canal sealer and filler based on pozzolan cement that has excellent physical and biological properties of MTA. It is part of the family of products known as calcium silicate-based endodontic sealers. Endoseal is premixed and pre-loaded in a syringe that allows direct application of the sealer into the root canal without requiring powder/liquid mixing, unlike other products. The product has outstanding flowability and maneuverability, which makes it possible to completely fill the root canal system including accessory and lateral canals. It is eugenol-free and will not impede adhesion inside the root canal.

Endoseal MTA Indications
ENDOSEAL MTA is developed for root canal filling and root perforation repair, effectively preventing periapical tissue irritation as well as secondary infection.

• Permanent obturation of the root canal system
• Root perforation repair
• Pulp revascularization
• Premixed and pre-loaded in a syringe: No powder/liquid mixing required 

Endoseal composition: calcium silicates, calcium aluminates, calcium aluminoferrite, calcium sulfates, radiopacifier, thickening agent 

Endoseal MTA Properties

Endoseal MTA Science and Technology

The inside of the root canal system has high humidity due to residual moisture in the dentinal tubules. MTA solidifies into a hard structure by absorbing the moisture from the surrounding tissue and has outstanding sealing capacity and biocompatibility. Therefore, it is appropriate for root canal treatment. Endoseal MTA solidifies by absorbing the moisture from the surrounding tissue and producing calcium hydroxide during the process that penetrates into the dentinal tubules, and it creates hydroxyapatite extensively. In addition, it induces regeneration of the surrounding damaged hard tissue.

Endoseal MTA Biocompatibility

Since Endoseal MTA is a root-end filling material based on MTA, it has superior biocompatibility and little inflammation. These characteristics of Endoseal MTA have been verified by many researchers and published at SCI journals.

Endoseal MTA Antibacterial effect

Endoseal MTA has a high PH and excellent antibacterial effects. E. faecalis, which is most commonly observed in teeth where endodontic treatment has failed, is very difficult to control with conventional intracanal instruments and cleansing, and is resistant to intracanal medicament. If a root canal sealer has antibacterial effects against E. faecalis, the root canal treatment will have higher predictability.

Endoseal MTA Hermetic sealing

2% dimensional change of Endoseal MTA occurs only during the setting process. Afterward, it rarely expands as shown in the table. In addition, Endoseal MTA is naturally penetrated even into unreachable spaces, where a dentist could not fill, during complete hardening time (12 hours).

Endoseal MTA Hard Tissue formation

Endoseal MTA not only has excellent sealing ability, but it also promotes hard tissue formation around the infected tooth. The superior ability of the hard tissue formation can be seen by various genetic tests.

Directions for Storage and Precautions

• Endoseal MTA starts to harden when it is exposed to moisture in the air, and in the root canal. If you leave the tip in place, the front part of the tip will harden, which will result in sealing. The plastic or needle tip, however, does not guarantee complete long-term sealing. Therefore, after unpacking and using the product the first time, regular reuse at least once a week is recommended to avoid the gelation of the front end of the product. If the product has not been used for a long time remove the inserted tip, squeeze a little, and insert a new tip.
• Pulling back the plunger will cause the moisture in the air to come inside the syringe, which will cause the product to harden. Thus, never pull back the plunger.
• Overfill may occur if the plastic or needle tip is stuck in the canal. Inject the product with the tip loose in the root canal.
• Use the product without the master cone for primary and permanent teeth under orthodontic treatment.
• Recap the needle tip after use for storage.
• Before reuse, check if the product can be smoothly squeezed out at the tip like a waterdrop and insert it in the root canal.
• Completely dry the root canal before obturation.
• Moisture in the root canal will greatly accelerate the gelation of the product.
• Filling with Endoseal without gutta-percha will also ensure good outcomes.
