• Submission Type: Traditional
• Regulation: 21 CFR 872.3820
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The Bi-Directional Spiral & Epoxy Root Canal Cement System is indicated for permanent sealing of root canals following established endodontic procedures.

Device Story

Obturation system for filling straight and minimally curved root canals. Kit includes bi-directional spirals and two-component epoxy root canal cement (powder and gel). Clinician uses bi-directional spiral to apply cement to canal walls; technique prevents cement extrusion beyond apex. System used in conjunction with gutta percha points. Epoxy/amine reaction causes setting. Provides seal equivalent to lateral condensation and thermoplastic gutta percha. Noneugenol-based formulation ensures compatibility with resin restoration procedures. Used by dentists/endodontists in clinical settings.

Clinical Evidence

No clinical data. Substantial equivalence supported by bench testing of physical properties (flow, film thickness, dimensional stability, solubility, disintegration) per ADA Specification No. 57/ISO 6876 and biocompatibility literature review.

Technological Characteristics

Two-component epoxy resin system (powder/liquid). Contains silver radiopaquing agent and bisphenol epoxy resin. Includes ISO size 25 bi-directional spirals. Meets ADA Specification No. 57 and ISO 6876 standards. Non-eugenol formulation.

Indications for Use

Indicated for permanent sealing of root canals following established endodontic procedures in patients requiring endodontic treatment.

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.

Predicate Devices

# 510(K) SUMMARY

This summary of 5l0(k) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR §807.92.

The assigned 5l0(k) number is: _______________________________________________________________________________________________________________________________________________

## 1. Submitter's Identification:

MDS 119 West 57th Street Suite 700 New York, NY 10019

Date Summary Prepared: August 4, 1999

Contact: Dr. Barry Lee Musikant

## 2. Name of the Device:

Bi-Directional Spiral & Epoxy Root Canal Cement System

### 3. Predicate Device Information:

1. AH-26® Root Canal Sealer (Pre-Amendment Device)

- 2. AH® PLUS® Root Canal Sealer, K# 960548, Dentsply International, York, PA
### 4. Device Description:

The subiect device is an obturation system for filling straight and minimally curved canals. The bi-directional spiral and epoxy root canal cement, combined with a single point technique, creates a seal equivalent to lateral condensation and thermoplastic gutta percha. Contained in the kit are the following:

4 - Color Coded to ISO Size 25 Bi-Directional Spirals (1-21 mm length and 3-25 mm length) 7.5 gm - Epoxy Root Canal Cement Gel 8.0 gm - Powder (Epoxy Root Canal Cement) 1 Measuring Scoop

### 5. Intended Use:

The Bi-Directional Spiral & Epoxy Root Canal Cement System is indicated for permanent sealing of root canals following established endodontic procedures.

{1}------------------------------------------------

## 6. Comparison to Predicate Devices:

The Bi-Directional Spiral & Epoxy Root Canal Cement System and its predicates are all endodontic sealing cements containing two-component systems. The AH® PLUS® Root Canal Sealer is a two-paste system (Paste A is an epoxy resin paste and Paste B is amine-containing paste), whereas the AH-26® and subject device endodontic cements are based on a powder-liquid mix. All device' two-component systems react via an epoxide/amine reaction to cause setting, and thus used in conjunction with the same auxillary materials in the root canal (i.e., gutta percha points).

The subject device is a derivative of AH-26® (a well-know epoxy-resin cement that has been reported favorably in the dental literature for more than 45 years). The subject device is noneugenol-based (no incompatibility with subsequent resin restoration procedures). Both the AH-26® and subject device use silver as the primary radiopaquing agent and a bisphenol epoxy resin as the liquid/gel. The powder and liguid systems of both AH-26® and subject device filling cement allows the clinician to choose the viscosity of the material. The AH® PLUS® Root Canal Sealer and AH-26® Root Canal Sealer are compatable in setting time, flow, shrinkage and microleakage physical property values. The difference between the subject device and the AH-26® device is that subject device uses a bi-directional spiral technique that thoroughly coats the walls of the canal without letting any cement flow beyond the apex during the application process.

## 7. Discussion of Non-Clinical Tests Performed for Determination of Substantial Equivalence are as follows:

Bench Testing performed on the components (contained in the kit) of the Epoxy Root Canal Cement meet/exceed ADA Specification No.57 ISO 6876 (Dental Root Canal Filling Material) and (Endodontic Filling Materials) to include physical properties such as flow, film thickness, dimensional stability, solubility and disintegration. Bi-Directional Spiral (reverse spiral drill) dimensional inspections are checked against approved meeting all required specifications

## 8. Discussion of Clinical Tests Performed:

Biocompatibility literature supplied with this 510(k) submission along with Material Safety Data Sheets, has shown that components contained in the Bi-Directional Spiral & Epoxy Root Canal Cement System, as well as in the predicate devices, do not raise any new safety/biocompatibility concerns.

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

## 9. Conclusions:

The Bi-Directional Spiral & Epoxy Root Canal Cement System has the same intended use and similar technological characteristics as the predicate devices. Moreover, bench testing contained in this submission and clinical literature supplied demonstrate that any differencies in their technological charactertics do not raise any new questions as to safety or effectiveness. Thus, the Bi-Directional Spiral & Epoxy Root Canal Cement System is substantically equivalent to the predicate devices.
