Intended Use

TRC-Pex The TRC-Pex is a temporary root canal sealer for use in the treatment of root canals, following a pulpectomy or for apexegenesis or apexification. Radic-Sealer The Radic-Sealer is a root canal sealer for permanent sealing of root canals following established endodontic procedures and may be used in conjunction with the auxiliary materials in the root canal (i.e. gutta percha points). The Radic-Sealer is intended for use by qualified healthcare personnel trained in its use.

Device Story

TRC-Pex and Radic-Sealer are endodontic materials. TRC-Pex: calcium hydroxide and iodoform-based temporary filling material; pre-mixed; supplied in plastic syringe with plunger, tips, and direction control holder; injected into canal. Radic-Sealer: epoxy-amine resin-based permanent sealing material; supplied in dual-chamber syringe for mixing; used with gutta percha points to achieve permanent obturation via adhesion to canal walls. Used in dental clinics by qualified healthcare personnel. Output is physical filling/sealing of root canal space. Benefits include effective temporary or permanent canal obturation during endodontic procedures.

Clinical Evidence

Bench testing only. Performance testing conducted per ISO 6876 (radiopacity, liquidity, setting time, solubility, film thickness, flowability) and biocompatibility testing per ISO 10993 (cytotoxicity, oral mucous irritation/sensitization, short-term systemic toxicity). Results demonstrate equivalence to predicate devices.

Technological Characteristics

TRC-Pex: Calcium hydroxide and iodoform-based paste. Radic-Sealer: Epoxy-amine resin-based. Delivery: Plastic syringes (single for TRC-Pex, dual-chamber for Radic-Sealer). Testing standards: ISO 6876 (performance), ISO 10993 (biocompatibility). No software or electronic components.

Indications for Use

Indicated for patients requiring root canal therapy. TRC-Pex is for temporary sealing following pulpectomy, apexogenesis, or apexification. Radic-Sealer is for permanent sealing of root canals in conjunction with auxiliary materials like gutta percha points. Intended for use by trained healthcare personnel.

Regulatory Classification

Identification

#### Device Description: 5.

### TRC-Pex

TRC-Pex is an immediately available pre-mixed root canal filling material based on Calcium Hydroxide and lodoform. This pre-mixed temporary filling material maintains a constant flow, which makes it easy to inject into the canal. Depending on apicoectomy or root canal therapies, it can be used as a temporary root canal filling material. The device is contained in a plastic syringe and the system includes a plunger, disposable tips, a rubber, a protective cap, an indo stop and a holder for direction control of the tip.

### Radic-Sealer

Radic-Sealer is a root canal sealing & filling material based on epoxy-amine resin. Radic-Sealer is contained in a dual syringe which makes it easy to mix and inject. It makes permanent obturation of root canals using adhesion properties between root canal walls and the root canal filling materials. The base and catalyst are contained separately in the chambers of two separate plastic syringes. The product consists of a mixing tip with a mixing joint, a protective cap, a mixing pad, and a plunger.

#### 6. Intended Use:

### TRC-Pex

The TRC-Pex is a temporary root canal sealer for use in the treatment of root canals, following a pulpectomy or for apexegenesis or apexification.

### Radic-Sealer

The Radic-Sealer is a root canal sealer for permanent sealing of root canals following established endodontic procedures and may be used in conjunction with the auxiliary materials in the root canal (i.e. gutta percha points). The Radic-Sealer is intended for use by qualified healthcare personnel trained in its use.

#### 7. Substantial Equivalence

The TRC-Pex and the Radic-Sealer are substantially equivalent to the predicate devices

{2}------------------------------------------------

### KM Corporation

with respect to intended use, accessory components, delivery method, and physical properties. The difference is the compositions of raw materials; however, the biocompatibility and the performance testing results show that this difference does not raise issues in safety and effectiveness.

#### Performance Data(Non-Clinical): 8.

The following properties were tested based on the referenced standards.

- · ISO 6876 Radiopacity, Liquidity, Setting time, Solubility test, Film Thickness, Flowability
- · ISO 10993-5 Cytotoxicity
- · ISO 10993-10 Oral Mucous Irritation & Sensitization
- · ISO 10993-11 Short-term systemic toxicity (Oral)
- · Other bench testing Shelf life, appearance, volume/weight spec, and packaging tests

Performance testing that confirmed to the protocols and recommended values described in ISO 6876 was performed. We believe that the performance data provided demonstrate that TRC-Pex and Radic-Sealer are substantially equivalent to the predicates in design, principle of performance, and technology.

Biocompatibility data were provided to demonstrate substantial equivalence to the predicate devices. Side-by-Side cytotoxicity testing was performed that compared the TRC-Pex and a predicate device, and the test results showed that they have similar biocompatibility properties.

The bench and biocompatibility tests provided evidence that the chemical and physical properties of TRC-Pex and Radic-Sealer are substantially equivalent to the predicate devices.

#### Conclusion: 9.

Based on the testing results, KM Corporation concludes that the TRC-Pex and the Radic-Sealer are substantially equivalent to predicate device in safety, effectiveness and performance.
