Intended Use

DRFP propoint obturation points are designed for permanent sealing of root canals when used with DRFP smartpaste dental sealer or with EndoSequence® BC Sealer following established endodontic procedures by qualified healthcare professionals.

Device Story

DRFP propoints are radiopaque, hydrophilic polymer-coated obturation points used for root canal sealing. The hydrophilic coating expands radially upon contact with moisture to fill canal irregularities and voids, creating a mechanical seal with dentine without exerting pressure on tooth structures. The device is used by dentists in clinical settings. Propoints are inserted into the root canal after the application of a compatible sealer (EndoSequence® BC Sealer or DRFP smartpaste). No heating or compression equipment is required; post-insertion procedures can begin immediately. The system benefits patients by providing a tight, biocompatible seal, reducing the risk of leakage, and facilitating potential future revision procedures due to the material's properties. The healthcare provider uses the device to achieve permanent obturation, with clinical success monitored via X-rays.

Clinical Evidence

Clinical evidence based on 18 months of use across approximately 2,000 treatments by a user panel of dentists. Reported a 0.8% failure rate, primarily attributed to tooth-related issues rather than material failure. Clinical X-rays confirmed effective bonding and healing. Bench testing included in-vitro dye penetration tests on heat-sterilized extracted teeth, showing no dye ingress, and chemical compatibility testing with sodium hypochlorite and EDTA.

Technological Characteristics

Radiopaque core with opaque hydrophilic cross-linked polymer coating. Biocompatible materials per ISO 10993 and ISO 7405. Available in 4%, 6%, PT, and S sizes. Non-heated, non-compressed manual insertion. Standalone dental device.

Indications for Use

Indicated for permanent root canal sealing in patients requiring endodontic obturation. Contraindicated in pregnant women and nursing mothers.

Regulatory Classification

Identification

A root canal filling resin is a device composed of material, such as methylmethacrylate, intended for use during endodontic therapy to fill the root canal of a tooth.

Obturation System

propoints (4%, 6%, PT, S) Obturation Points smartpaste Sealer with Active Powder

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

#### propoint Obturation Points 5.7.1

The propoints are identical to the points cleared for marketing with K100248. They are made of a radiopaque core and an opaque hydrophilic coating of cross-linked hydrophilic polymers that have been used in the contact lens industry for more than 20 years.

propoints are offered in the traditional 4% and 6% sizes and for use with variable taper files (such as ProTaper™ and Sendoline S5™). They are biocompatible and fully opaque. The hydrophilic coating expands radially to push the sealer into irregularities and voids present in the root canal system for a tight mechanical seal with the dentine. The coating only expands into available space and does not exert pressure on tooth structures. Dimensional length stability is maintained.

The points are packaged in clean room 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. The hydrophilic properties of the device allow extraction without softeners in revision procedures.

propoints are

- coated with DRFP smartpaste prior to insertion into the root canal . (K100248) or
- inserted after the root canal has been filled with EndoSequence® BC. .

To demonstrate the safety and effectiveness of root obturations with this sealer is the subject of this submission.

#### EndoSequence® BC Sealer 5.7.2

NOTE: Only the interaction with this sealer, not the device itself, is the subject of this submission.

It "is a convenient premixed ready-to-use injectable white hydraulic cement paste developed for permanent root canal filling and sealing applications. EndoSequence® BC (iRoot SP) is an insoluble, radiopaque and aluminum-free material based on a calcium silicate composition, which requires the presence of water to set and harden. The sealer does not shrink during setting and demonstrates excellent physical properties." 2

#### 5.8 Statement of Intended Use [807.92(a)(5)]

DRFP propoint obturation points are designed for permanent sealing of root canals when used with DRFP smartpaste dental sealer or with EndoSequence® BC Sealer following established endodontic procedures by qualified healthcare professionals.

Federal US Law restricts propoints (K100248) and Brasseler EndoSequence® BC (K080917) to sale by or on the order of a dentist.

#### Comparison with Predicate Devices [807.92(a)(6)] 5.9

The use of propoints with Brasseler EndeSequence® BC Sealer for root canal obturations is substantially equivalent to the performance of the DRFP ProSmart Root Canal Obturation System (K100248).

## 5.10 Performance Data (807.92(b)]

5.10.1 BenchTests (807.92(b)(1)

DRFP propoints used with EndoSequence® BC Sealer:

- In-Vitro Dye Penetration and Sealing Test to Validate 1) Effective Seal
Heat-sterilized extracted teeth (more brittle and desiccated than patients' teeth), filled with EndoSequence® and propoints and immersed in Brilliant Blue Dye solution for at least one week, showed no sign of dye ingress after sectioning and assessment under a microscope.

Includes immediate tooth failures such as fracturing, canal ossification, teeth requiring extraction n

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

#### 2) Exposure to Sodium Hvpochlorite

The manufacturer recommends to rinse the canal three (3) times prior to insertion of the endodontic components. If this regime is followed, the remaining value of 0.01% sodium hypochlorite will have no effect on the safety and effectiveness of the devices.

#### 3) Exposure to EDTA

- Undiluted 17% EDTA has shown to have no effect on the system. 4) Radiopacity
- Clinical x-rays validate the excellent radiopacity of both devices.

### 5.10.2 Clinical Performance (807.92(b)(2)

18 months of clinical use demonstrate that propoint and EndoSequence® Sealer form an effective and safe system for the obturation of root canals. Out of approx. 2000 treatments, the DRFP User Panel of practicing dentists reports a 0.8% failure rate that is predominantly attributed to tooth rather than material oroblems. An abundance of clinical x-rays confirm effective bonding to tooth structures and provide evidence of good healing.

## 5.10.3 Conclusion (807.92(b)(3)

Bench test results and clinical evidence based on more than 2000 treatments performed by DRFP User Panel of practicing dentists, including x-rays, show that DRFP propoints with Brasseler USA EndoSequence ® BC sealer form an effective system for root canal obturations.

#### Contraindications 5.11

The manufacturer recommends to not use the system in pregnant women and in nursing mothers.

#### 5.12 Information Bearing on Safety and Effectiveness [807.92 (b)(3)]

. . . .

The materials used in DRFP propoints and EndoSequence® BC Sealer have a long history of safe and effective use in dental and other medical devices.

Biocompatibility testing according to ISO 10993 and ISO 7405 has shown the materials to be non-toxic, non-carcinogenic and biocompatible with tissue fluids . There are no characteristics known that should adversely affect the safety and effectiveness of this device combination.

Performance bench test results and abundant clinical data demonstrate that DRFP propoints in combination with Brasseler USA EndoSequence® BC Sealer form an effective and safe system for the obturation of dental root canals and that it is substantially equivalent to the predicate.

The results of design validation and non-clinical and clinical performance testing raise no new issues of safety and effectiveness.
