Intended Use

The DRFP ProSmart Root Canal Obturation System is designed for permanent sealing of root canals following established endodontic procedures by qualified healthcare professionals. The ProSmart Root Canal Obturation System is intended for Prescription Use.

Device Story

ProSmart Root Canal Obturation System provides permanent root canal sealing. System consists of ProPoints (radiopaque core with hydrophilic coating) and ProRes Sealer (epoxy-amine resin paste with active powder). Clinician applies ProRes paste to ProPoints before insertion into prepared root canal. Hydrophilic components absorb moisture, causing radial expansion into dentine tubules and irregularities to create mechanical seal. No heating or compression equipment required. Used in dental clinics by dentists. Benefits include tight seal, dimensional stability, and ease of revision without softeners. Output is physical obturation of canal, verified by clinician via X-ray.

Clinical Evidence

Clinical evaluation based on an ongoing, controlled three-year investigation in Europe. Data from one-year follow-up of treated teeth showed 33% healed, 35% improved, 25% stable periapical tissue, and 6% widening of periodontal ligament. All treated teeth were symptom-free and functional; no extractions or retreatment required. Non-clinical bench testing included ISO 6876/6877 compliance, expansion testing, resistance to tooth cracking, and exposure to sodium hypochlorite/EDTA.

Technological Characteristics

System uses hydrophilic polymer technology. ProPoints: radiopaque core, hydrophilic translucent coating. ProRes Sealer: two-component epoxy-amine resin paste with active powder. Dimensions: 4%, 6%, PT, S tapers. Connectivity: N/A. Sterilization: Clean conditions packaging. Standards: ISO 6876:2001, ANSI/ADA Specification #57, ISO 6877:2006, ADA/ANSI Specification #78, ISO 10993, ISO 7405.

Indications for Use

Indicated for permanent sealing of root canals following endodontic procedures in patients requiring root canal therapy. Contraindicated in pregnant women and nursing mothers.

Regulatory Classification

Identification

### 2.7 Device Description [807.92(a)(4)]

The ProSmart Root Canal Obturation System is using hydrophilic polymer technology. This causes the material to expand into irregularities and tubules of the root canal to assure a tight mechanical seal with the dentine. The hydrophilic properties of the system allow extraction without softeners in revision procedures.

#### 2.7.1 ProPoint Obturation Points

ProPoints are offered in the traditional 4% and 6% sizes and for use with variable taper files (such as ProTaper™ and Sendoline S5™). The radiopaque core is coated with hydrophilic, translucent material that expands radially up to 20% (6% points) while maintaining dimensional length stability.

The points are packaged in clean conditions and come individually wrapped to prevent cross-contamination. They can be cut to exact tip size and length.

No heating or compression equipment is required. Post insertion can commence immediately after root canal has been filled.

ProPoints are coated with ProRes paste prior to insertion into the root canal.

#### ProRes Paste 2.7.2

Is a two-component base:catalyst paste based on epoxy-amine resin chemistry. It is packaged in a dual-syringe for easy and consistent mixing.

The paste comes with a carefully formulated 'Active Powder'. Mixing a tiny scoop of this material into the prepared ProRes will provide the paste with hydrophilic properties that uses the moisture present in the root canal to expand into crevices and dentine tubules for a tight mechanical seal with the tooth dentine.

### 2.10. Performance Data [807.92(b)]

### 2.10.1 Non-Clinical PerformanceTests (807.92(b)(1)

### Handling & Setting Characteristics ProRes Sealer:

| Parameter | Acceptable Limit<br>(ISO 6876:2001 & ANSI/ADA<br>Specification # 57) | Results |
|----------------|----------------------------------------------------------------------|---------------------|
| Flow | Not less than 20mm | 44mm |
| Working time | Not less than 90% stated by manufacturer | 35 mins at 37°C |
| Setting time | Within range stated by manufacturer | 45 mins at 37°C |
| Film thickness | Not more than 50 $ \mu $ m | 3.3 $ \mu $ m |
| Solubility | Shall not exceed 3% | 0.0324% |
| Radiopacity | Not less than 3mm Al equivalent | 5.4mm Al equivalent |

### ProSmart System:

#### 1) Expansion on Hvdration

Propoints coated with prores expand up to 20%.

- Worst Scenario Bench Test of Resistance to Tooth Cracking 2) Due to Hydrophilic Expansion
Insertion of prores-coated propoints in heat-sterilized extracted teeth (more brittle and desiccated than patients' teeth), showed no sign of cracking or damage due to product expansion.

- Exposure to Sodium Hypochlorite 3)
The manufacturer's recommends to rinse the canal three (3) times prior to insertion of the system. If this regime is followed, the remaining value of 0.01% sodium hypochlorite will have no effect on the safety and effectiveness of the device.

#### Exposure to EDTA 4)

Undiluted 17% EDTA has shown to have no effect on the system.

#### 5) Radiopacity

Extensive testing and continuous interaction with practicing dentists after three (3) years of use in Europe demonstrate adequate radiopacity for the intended purpose. The dentist is able to

- verify that the obturation point is located in the correct . position and has the correct working length

{3}------------------------------------------------

## K 100248

- assure that it has not penetrated the apex and as a . medical record to
- assess healing

### ProPoint Obturation Points:

#### 1) ISO 6877:2006

All applicable performance testing showed the points to be in full compliance with this standard. Since the standard was developed with reference to traditional Gutta Percha points, additional device-specific testing was performed regarding:

- Expansion on Hydration .
- Bonding of Sheath to Core .
- Flexibility .
- Geometry .
- Radiopacity and Analysis of Core Materials .
- In-Vitro Dye Penetration and Sealing Tests .
- CT Scans and X-Ray Photographs

Test results demonstrate that propoints are safe and effective for the intended purpose.

#### 2) ADA/ANSI Specification # 78

DRFP propoints comply with all relevant requirements. Due to device-specific material differences when compared to Gutta Percha, propoints differ in

- Color = white core and translucent coating
- = radiopaque core and radiolucent coating Radiopacity

propoints are visible in the filled root canal when x-rayed so that the endodontist can verify the effectiveness of the obturation

### 2.10.2 Clinical Evaluation (807.92(b)(2)

Radiographic images of an on-going, controlled three-year investigation to evaluate the ease of use by operating dentists, the handling characteristics and the specific root filling techniques of the ProSmart System, demonstrate after one year:

- 33% healed ●
.

- 35% improved .
- 25% same periapical tissue .
- 6% widening of the periodontal ligament (This is an assessment of . the state of tissue surrounding the base of the tooth and not an effect caused by the ProSmart system)

All teeth treated with ProSmart Root Canal Obturation System, were

- symptom-free and in function; .
- No teeth had to be extracted .
- None had to be retreated or required a clinical intervention .

Clinical evidence after close to three (3) years of use in Europe confirms these findings.
