Intended Use

EndoREZ is designed to be used with EndoREZ Points and/or gutta percha for the filling of cleaned and shaped root canals. EndoREZ, in conjunction with a master cone and accessory cones (as needed), provides optimum sealing. Although EndoREZ Points are recommended, EndoREZ may be used with all conventional endodontic obturation techniques.

Device Description

A unique biocompatible methacrylate-based root canal sealer/filler, EndoREZ is a two part, mixed, dual cure material with optional EndoREZ Accelerator included. EndoREZ has hydrophilic characteristics providing excellent penetration into dentinal tubules. This allows for improved sealing properties combined with ease of placement and removal. Radiopacity equivalent to gutta percha simplifies radiographic interpretation. EndoREZ does not compromise the function of dentin bonding agents or luting resin polymerization.

AI/ML Overview

The document describes a 510(k) submission for the EndoREZ® Dual Cure with Accelerator, a dental device for root canal filling. The submission focuses on demonstrating substantial equivalence to a predicate device, rather than proving independent effectiveness through a clinical study with detailed acceptance criteria and performance metrics.

Therefore, the requested information regarding acceptance criteria, study details, sample sizes, expert ground truth, adjudication methods, MRMC studies, and training set information is either not applicable or not provided in this type of regulatory document.

Here's a breakdown based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Not Applicable / Not Provided.

This document is a 510(k) Summary, which aims to demonstrate "substantial equivalence" to a legally marketed predicate device, not necessarily to prove a device meets specific performance acceptance criteria through a standalone clinical study with reported metrics. The submission focuses on comparing characteristics and safety to an existing device.

Acceptance CriteriaReported Device Performance
None explicitly stated related to performance metrics for a specific clinical outcome.The document states "The results of biocompatibility testing demonstrate that the EndoREZ Dual Cure used with the EndoREZ Accelerator is compatible with its intended use as a root canal filler/sealer." This is a qualitative statement about compatibility, not a quantitative performance metric against an acceptance criterion.
Implicit criterion: Substantial Equivalence to Predicate Device (EndoREZ Dual Cure, K042756)The conclusion states: "EndoREZ Dual Cure used with the EndoREZ Accelerator... is substantially equivalent to the EndoREZ Dual Cure used alone... The two products are composed of nearly the same materials, have the same intended use and technological characteristics, and both are safe and effective when used for the indications described."

2. Sample Size Used for the Test Set and Data Provenance

Not Applicable / Not Provided.

No test set or clinical study with a specified sample size is described for the evaluation of the device's performance against specific acceptance criteria. The basis for equivalence relies on material comparison and biocompatibility testing. The data provenance (country, retrospective/prospective) is also not applicable as a clinical study is not detailed.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

Not Applicable / Not Provided.

No clinical test set requiring expert ground truth establishment is described in this document.

4. Adjudication Method for the Test Set

Not Applicable / Not Provided.

Since no clinical test set is described, an adjudication method is not relevant.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size

Not Applicable / Not Provided.

This document does not describe an MRMC comparative effectiveness study. The evaluation focuses on material properties and intended use.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Not Applicable / Not Provided.

This is a medical device (root canal sealer/filler), not an AI algorithm. Therefore, "standalone (algorithm only)" performance is not relevant.

7. The Type of Ground Truth Used

Not Applicable / Not Provided.

As no clinical study with a test set is detailed, there's no mention of expert consensus, pathology, or outcomes data as ground truth. The primary "truth" being established is substantial equivalence through chemical/physical property comparison and biocompatibility testing.

8. The Sample Size for the Training Set

Not Applicable / Not Provided.

This refers to an AI/machine learning context, which is not relevant for this medical device submission.

9. How the Ground Truth for the Training Set Was Established

Not Applicable / Not Provided.

This refers to an AI/machine learning context, which is not relevant for this medical device submission.

Technological Characteristics

EndoREZ Dual Cure is a methacrylate-based root canal sealer/filler consisting of a twopart, mixed, dual-cure, radiopaque material with hydrophilic characteristics that allow for penetration into dentinal tubules. The formulation of the base and catalyst of the Dual Cure are the substantially the same as in K042756.

An accelerant is being added to the obturation kit and is also available separately that may be used in conjunction with the EndoREZ Dual Cure. The Accelerator will be provided in a unit dose vial (35 µL per vial) for use with EndoREZ Points (or, alternatively, gutta percha). The points (or gutta percha) are dipped into the Accelerator then placed in the root canal. When the Dual Cure comes in contact with the dipped points, the curing reaction is accelerated from 12 - 20 minutes to 4 - 6 minutes.

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

The Accelerator is comprised of three proprietary elements. Two of the elements are also components of the Dual Cure (a monomer and an inhibitor). The third element is commonly used as an accelerant in polymerization reactions in dental resin fillings and bone cements.

Brief Description of Testing Performed

Each lot of product must pass internal test specifications prior to release. The results of biocompatibility testing demonstrate that the EndoREZ Dual Cure used with the EndoREZ Accelerator is compatible with its intended use as a root canal filler/sealer.

Conclusion and Substantial Equivalence

In conclusion, the EndoREZ Dual Cure used with the EndoREZ Accelerator, to be manufactured and marketed by Ultradent Products, Inc., 505 West 10200 South, South Jordan, UT 84095, is substantially equivalent to the EndoREZ Dual Cure used alone, also manufactured by Ultradent Products, Inc. The two products are composed of nearly the same materials, have the same intended use and technological characteristics, and both are safe and effective when used for the indications described.
