Auroseal M.T.A. Kit – Eugenol-Free Endodontic Cement

AUROSEAL – Eugenol-Free Endodontic Cement for Complex Clinical Cases

AUROSEAL is an innovative, eugenol-free endodontic cement formulated to address a range of clinically challenging applications. Composed of modified mineral oxides, its hydrophilic nature ensures a reliable seal even in the presence of blood or other organic fluids. The cement develops a high pH during setting, which helps limit bacterial proliferation, while its biocompatible properties support the healing process.

Mixed exclusively with water, AUROSEAL avoids the drawbacks of traditional eugenol-based cements, such as potential irritation and poor adhesion in less-than-perfectly dry environments.

Key Benefits

• Eugenol-free formulation – reduces risk of irritation and improves adhesion in moist conditions.
• Hydrophilic mineral oxides – maintain seal integrity even in the presence of blood or organic fluids.
• High pH during setting – limits bacterial growth.
• Biocompatible – promotes healing processes.
• Simple mixing with water – no additional solvents required.

Composition

• Powder: Mixture of aggregated mineral oxides (M.T.A.) based on Portland cement, with setting regulators, plasticizers, and radiopacifiers.
• Liquid: Distilled water in single-dose strips.

Indications for Use

• Repair of root perforations
• Retrograde fillings in surgical endodontics
• Filling of the apical third in teeth with open apex and inactive Hertwig’s sheath

Instructions for Use

Mix the contents of one vial with 3–4 drops of liquid using the supplied mixing pad. Mix thoroughly until the product achieves a creamy, dense, and uniform consistency.

Working time at 20°C: approximately 3–5 minutes. This cannot be extended by re-spatulating the cement on the pad and adding liquid.

After application, compact the material with a slightly moistened cotton pellet. Setting is favored by maintaining a humid environment. After 72 hours, restorative treatments can continue. Optimal mechanical performance is achieved after complete setting, which occurs after approximately 28 days.

Application Methods

Repair of Root Perforations

1. Isolate the operative field with a rubber dam.
2. Clean and shape the root canal.
3. Control bleeding and dry the root canal.
4. If sufficient drying is not possible due to inflamed tissues or active suppuration, perform a treatment with calcium hydroxide (Endoidrox) and temporize the tooth with a temporary filling. After one/two weeks, remove the calcium hydroxide and proceed to dry the canal.
5. Achieve apical endodontic seal using normal endodontic filling techniques with thermoplastic gutta-percha.
6. Remove debris and filling material from the perforation.
7. Revise the root perforation and control bleeding.
8. Mix AUROSEAL and place it in the perforation with a spatula or a plugger of appropriate size.
9. Place a pellet moistened with water over the AUROSEAL and temporize the tooth with a temporary filling.
10. After one week, re-intervene to check setting, then proceed with definitive restoration.

Retrograde Filling in Surgical Endodontics

1. Gain surgical access and expose the apex.
2. Resect the apex with a bevel cut at minimal angulation.
3. Revise the surgical cavity and remove all granulomatous residues.
4. Prepare the retrograde cavity using ultrasonic instruments or a micro-head handpiece.

Note: To obtain an appropriate seal, prepare a canal section of at least 3 mm.

5. Control bleeding.
6. Mix AUROSEAL (one dose of powder and 3–4 drops of liquid) and place it in the retrograde cavity with a moistened spatula.
7. Compact the material with a suitable retrograde compactor.
8. Thoroughly clean the surgical cavity and flap to remove debris, then proceed to suture (after placing AUROSEAL, it is possible to fill the bone defect with osteoconductive materials).
9. Reposition and suture the surgical flap.
10. Perform follow-up with intraoral radiographs at 3, 6, and 12 months.

Filling of the Apical Third in Teeth with Open Apex and Inactive Hertwig’s Sheath

1. Isolate the operative field with a rubber dam.
2. After gaining access to the root canal system, perform usual endodontic instrumentation with mechanical and/or manual means, alternating irrigations with sodium hyp
