Angelus MTA Fillapex - Bioceramic root canal sealer
Properties of MTA Fillapex
Chemical
A. Setting Time
MTA-Fillapex showed average setting time of 130 minutes (2 hours and 10 minutes) with a variation of ±10 minutes.
B. Solubility
The material showed a variation of 0.1%, after submission to the phenomenon of solubility, a value lower than the maximal variation accepted by ISO which is 3%.
C. Setting Expansion
The setting expansion of the material decreases apical leakage
Physical
A. Flow
MTA fillapex has optimized flow and a low film thickness for easy penetration into lateral & accessory canals
B. Radiopacity
The optical density of the sealer must be equal or superior to the area of the aluminum scale that corresponds to a thickness of 3 mm. Software Image J was used to calculate the optical density in pixels. MTA-Fillapex presented a value 146% superior to the 3 mm of the aluminum
C. Film Thickness
Proves its high filling capacity, even in secondary and accessory canals.
D. Dimensional Change
ISO sets that the average dimensional change of the material should not exceed 1.0% shrinkage or 0.1% expansion.
The material fulfilled the requirements standardized by ISO, with an average dimensional change = 0.088% expansion.
Biological
A. Sealing of root canals
MTA-Fillapex shows an optimized flow due to the nanoparticles. It provides excellent filling and sealing of the main and lateral canals.
Benefits
Why is the presence of MTA important in the composition of this product?
The MTA cement became available in the market in 1998 and it turned out to be a ''miraculous'' material in the field of Endodontics, due to the scientifically proven excellent results. MTA as a component means perfect sealing (provided by its setting expansion), sealing integrity (provided by its low solubility) and the highest biological regeneration (provided by the release of calcium ions and their antimicrobial action).
Does MTA-Fillapex replace the MTA Reparative Cement?
No. MTA-Fillapex is an endodontic sealer, while MTA Reparative is indicated for the treatment of perforations, root resorption, apical plug and pulp capping.
What is the working time of Fillapex?
The working time is 23 minutes, which allows the root canal filling to be calmly performed by both the general practitioner and the endodontist.
What is the setting time of Fillapex?
Two hours and thirty minutes. Important: MTA-Fillapex only sets in contact with moisture. Inside the root canal the moisture is derived from the dentinal tubules and from the periapical tissues. MTA-Fillapex will not set completely on the mixing pad.
Should MTA-Fillapex be used alone or associated with gutta-percha points?
Fillapex can be used in both techniques: associated with the points and also for root canal fillings without the points.
How radiopaque is MTA-Fillapex?
It is one of the most radiopaque endodontic sealers in the market.
Can MTA-Fillapex can be used in the thermal condensation technique?
The boiling point of Fillapex is 150ºC. If the equipment temperature is kept below this point, yes, Fillapex can be used.
Is MTA-Fillapex biocompatible with the tissues?
Yes. MTA-Fillapex presents two components that guarantee this property: MTA, known as the most biologically compatible endodontic material and the salicylate resin, an organic and therapeutic resin widely used in endodontic cements.
How can MTA-Fillapex be removed from the canal?
With the same techniques indicated for the other endodontic sealers.
Can MTA-Fillapex be kept in the refrigerator?
No. MTA-Fillapex is sensitive to moisture and should not be stored in the refrigerator.
How many cases can be made with one syringe/tube of Fillapex?
1 double syringe with 4 g provides an average of 15 cases, depending on the tooth being treated.
1 tube with 30 g provides an average of 200 cases, depending on the tooth being treated.
