Device Story

BIO-C SEALER ION+ is a ready-to-use, injectable bioceramic root canal sealer. It is supplied in a preloaded syringe with disposable intracanal tips for direct application into the root canal system by a dental professional. The material is insoluble and radiopaque; it requires moisture (from dentinal tubules or surrounding tissue) to initiate a hydration reaction that allows it to set and harden. During this process, the material releases calcium, magnesium, and silicon ions, and the presence of calcium sulfate increases the local pH. The device is used for permanent obturation of root canals and treatment of internal reabsorption. By providing a stable, biocompatible seal, it aids in the success of endodontic procedures.

Clinical Evidence

No clinical performance testing was conducted. Evidence is based on bench testing (ISO 6876:2012) including setting time, solubility, flow, film thickness, and radiopacity, alongside additional physical/chemical characterization (XRD, particle size, viscosity). Biocompatibility was established via ISO 10993-1:2009 testing, demonstrating the material is non-mutagenic, non-irritant, non-sensitizing, and lacks acute systemic toxicity.

Technological Characteristics

Bioceramic root canal sealer; composition: calcium and magnesium silicate, zirconium oxide (radiopacifier), silicon oxide (rheology agent), potassium sulfate, calcium sulfate. Form factor: pre-mixed paste in syringe with disposable tips. Principle: moisture-activated hydration/setting reaction. Non-sterile. Physical properties: radiopacity >= 7 mm Al, setting time 120-240 minutes.

Indications for Use

Indicated for sealing the root canal of permanent teeth and internal reabsorption treatment.

Regulatory Classification

| 3843 | BIO-C SEALER<br>ION+ | • 4 preloaded syringes with 0.5g each<br>• 20 disposable intracanal tips |
| 3845 | BIO-C SEALER<br>ION+ | • 1 preloaded syringe with 2g each<br>• 5 disposable intracanal tips |

#### INTENDED USE

Sealing the root canals.

#### INDICATIONS FOR USE

- 1. Sealing the root canal of permanent teeth;
- 2. Internal reabsorption treatment.

#### COMPARISON OF TECHNOLOGY

BIO-C SEALER ION+ and BIO-C SEALER are indicated for equivalent dental applications, have comparable chemical/physical properties and performance specifications and equivalent delivery systems (syringe and disposable intracanal tips). The reference device, ENDOSEAL MTA, contains a chemical component that is found in BIO-C SEALER ION+.

The similarities and differences of BIO-C SEALER ION+ and the predicates are discussed below:

{5}------------------------------------------------

- > BIO-C SEALER ION+, BIO-C SEALER and ENDOSEAL MTA are mainly composed of calcium silicates. BIO-C SEALER ION+ is composed of calcium and magnesium silicate, and BIO-C SEALER and ENDOSEAL MTA are composed of calcium silicates. Despite the difference between the silicates in the formulations, biocompatibility tests were conducted with the subject device and the results demonstrated that the device is biocompatible.
- v BIO-C SEALER ION+ and ENDOSEAL MTA uses calcium sulfate as setting agent, whereas BIO-C SEALER sets in the presence of moisture due to the hydration of the calcium silicates.
- v As BIO-C SEALER ION* and BIO-C SEALER are pre-mixed ready-to-use pastes, a biocompatible hydrophilic polymer is used in order to give an adequate viscosity and flow to the products. In this case, this polymer is included as a chemical component and is present in several cleared dental devices.
- ✔ Zirconium oxide is present all compositions. This component is responsible for the radiopacity of the products.
- V BIO-C SEALER ION+ and BIO-C SEALER use fumed silica (silicon oxide) as rheometry agent. This component is inert and the percentage of fumed silica used in both devices is highly similar.
- > All materials share the same Delivery System (syringe and disposable intracanal tips).
- V BIO-C SEALER ION+ and BIO-C SEALER are both provided non-sterile and have comparable setting time, solubility, flow, film thickness and radiopacity.

All materials are available as pre-mixed ready-to-use radiopaque pastes essentially designated for the equivalent dental applications and have comparable physical properties, performance specifications and share specific chemical components as can be seen above.

The table below summarizes the main similarities of BIO-C SEALER ION* and the predicate devices:

#### NON-CLINICAL PERFORMANCE TESTING

BIO-C SEALER ION* has undergone extensive bench testing. The following bench tests were performed according to ISO 6876:2012 Dental root canal sealing materials: setting time, solubility, flow, film thickness and radiopacity. Additional tests are also performed and incorporated into the product acceptance criteria: X-ray diffraction analysis, particle size analysis, viscosity and thixotropy tests and color determination analysis.

Biocompatibility tests were conducted with the subject device according to ISO 10993-1:2009 Biological evaluation of medical devices — Part 1: Evaluation and testing within a risk management process providing evidence that BIO-C SEALER ION+ is non-mutagenic, non-irritant to oral mucosa of hamsters, no sensitizing and has met the requirements of absence of acute systemic toxicity after single oral administration.

#### CLINICAL PERFORMANCE TESTING

Clinical performance testing was not conducted on the subject device.

#### CONCLUSION

Based upon a comparison of technology, non-clinical performance testing and similarity in intended use, we concluded that BIO-C SEALER ION* is substantially equivalent to the predicate devices.
