Can BIO-C SEALER be used without gutta-percha cones?

The technique recommended by the company is to use it with cones, as the cement is more difficult to remove if needed, due to its bioceramic characteristics.

What is the setting time of BIO-C SEALER?

The setting time is ≤240 minutes and depends on local humidity.

Should I leave the canal moist in order to use BIO-C SEALER?

No, moisture, which initiates the material setting, comes from apical tissues and dentinal canaliculi.

What is the resin used as base in BIO-C SEALER?

BIO-C SEALER has no resinous base. Its viscosity is given by a long-chain alcohol, the polyethylene glycol. Therefore, the product is more biocompatible and easier to clean.

How should I store BIO-C SEALER?

The storage should be in a dry ventilated place and it SHOULD NOT BE STORED IN THE FRIDGE.

Is BIO-C SEALER absorbable when overflown?

BIO-C SEALER contains in its composition calcium silicate, which in contact with the local humidity is hydrated, producing a hydrated calcium silicate structure and calcium ions and hydroxyl. A part of the material in the form of calcium ions and hydroxyl can be absorbed rapidly in contact with periradicular tissues if accidentally overflown. However, hydrated calcium silicate is a silica matrix, which together with the radiopacifier (zirconium oxide), represents the insoluble part of the product, and present high chemical stability, being difficult to absorb or solubilize.

What is the amount of bioceramic particles in BIO-C SEALER?

The product has 65% bioceramic content.

Can BIO-C SEALER be used in single cone techniques?

Yes, the product can be used for both single and accessory cone techniques.

What is the difference between BIO-C SEALER and MTA-Fillapex?

• BIO-C Sealer is a non-resinous ready-to-use bioceramic cement with 65% bioceramic charge.
• MTA-Fillapex is a resinous bioceramic cement (salicylate resin), pastexpaste, with 13% bioceramic charge in the product.

How many conduits are possible witch 1 BIO-C SEALER syringe?

It is possible to perform 10 to 12 root canals.

Can the Bio-C Sealer be used with the thermoplastic root canal filling technique?

In the root canal filling techniques that use gutta percha heating, the maximum temperature reached by the equipment is 200°C. The Bio-C sealer is stable at this temperature, unlike some other root canal sealers that degrade at temperatures close to 144ºC.

How long does the Bio-C Sealer alkaline reaction last?

The “alkaline reaction” is the hydration reaction of the product which, in contact with the moisture of the environment produces  Ca(OH)₂– calcium hydroxide and contributes to the increase in pH|alkalinity. Clinically, this hydration reaction depends a lot on the conditions of the root canal where the sealer will be inserted, which is a more or less humid canal. Under standardized conditions of humidity, the hydration reaction – “alkaline reaction” – takes an average of 28 days, however this process occurs in phases (I, II, III, IV and V) with variation in the amounts of Ca(OH)2 produced in the long-term.

In relation to the biological reaction, which product performs better, Bio-C Sealer or MTA-Fillapex?

The best biological reaction occurs with the Bio-C Sealer, due to its smaller particle size, which ends up being more reactive, and also the concentration of calcium silicate in the formulation (13% in MTA-Fillapex, and 70% in Bio -C Sealer).

When using bioceramic sealer, can we perform the restoration on the same day, or should we wait for the sealer to set completely?

When using Bio-C Sealer (or MTA-Fillapex), it is possible to proceed with the restoration of the dental element in the same session.

When using Bio-C Sealer, if we need to do an endodontic retreatment, what is the removal protocol?

The bioceramic root canal sealer can be removed with gutta-percha solvents (such as citric acid or eucalyptol), and with hand files and/or mechanized files, or using ultrasonic inserts.

If we perform the root canal filling with Bio-C Sealer without post preparation, can we do post preparation after the sealer setting?

Yes, if the preparation is not carried out immediately after the root canal filling, you should wait for the complete setting of the sealer and then proceed with the preparation for the placement of the post.

What is the management if there is an accidental extrusion of bioceramic sealer?

There is no need for any specific conduct. It is recommended to follow the case, and check remission of signs and symptoms.

Can we fill primary teeth with Bio-C Sealer?

Bio-C Sealer is only recommended for permanent teeth.
