Permanent root canal obturation

This product is the root canal sealer conforming to ISO 6876. This is a pre-loaded syringe type that does not require mixing and set by absorbing the moisture around the root canal.

The provided document describes a 510(k) premarket notification for a medical device called "White ENDOSEAL MTA," which is a root canal filling material. This submission focuses on non-clinical performance testing and does not involve a study proving the device meets acceptance criteria related to AI/ML or human-in-the-loop performance.

Therefore, most of the requested information regarding AI/ML-specific study design (such as sample sizes for test and training sets, expert adjudication, MRMC studies, standalone algorithm performance, and ground truth establishment) cannot be found in this document.

However, I can extract information related to the performance testing (non-clinical) performed for this device based on the provided text.

Here's the breakdown of the information that can be extracted, and an explanation of why other requested information is not applicable:

Information available from the document:

1. A table of acceptance criteria and the reported device performance

The document lists performance testing against ISO 6876 standards, which implicitly defines acceptance criteria. The reported performance for the proposed device (White ENDOSEAL MTA) is compared to the predicate device.

Note: The document states "All the test results met the preset test criteria," indicating compliance with the referenced standards (ISO 6876, ISO 10993 series) for the White ENDOSEAL MTA.

2. Sample sized used for the test set and the data provenance

• Sample Size: Not specified for the non-clinical tests. Non-clinical bench testing often uses small, controlled samples, but the exact number isn't in this summary.
• Data Provenance: The testing was conducted by "MARUCHI" (the manufacturer) or by testing institutions following specific ISO standards. The location is the Republic of Korea (manufacturer's address). The data is from non-clinical bench testing, not patient data.

Information NOT available or NOT applicable to this document:

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

• This document describes non-clinical laboratory testing (e.g., material properties, biocompatibility), not clinical studies involving expert interpretation of medical images or patient outcomes. Therefore, there is no concept of "ground truth" established by medical experts in this context.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

• Not applicable. This is for clinical study ground truth establishment, not non-clinical bench testing.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• Not applicable. This document is about a root canal filling material, not an AI/ML device for image interpretation or diagnosis. No human reader studies were mentioned.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

• Not applicable. This is not an AI/ML device.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc)

• For the non-clinical tests described, the "ground truth" is defined by the objective measurement parameters and specifications set forth by the international standards (ISO 6876, ISO 10993 series) and internal testing methods. There is no clinical "ground truth" derived from patients or expert consensus.

8. The sample size for the training set

• Not applicable. This is not an AI/ML device, so there is no training set.

9. How the ground truth for the training set was established

• Not applicable. As above, there is no AI/ML component or training set.

Summary:

This 510(k) submission for "White ENDOSEAL MTA" focuses on demonstrating substantial equivalence to a predicate device through non-clinical (bench and biocompatibility) testing, confirming it meets established international standards for root canal filling materials. It does not involve AI/ML technology, clinical performance studies, or the types of expert-driven data collection and analysis that would require answering questions 3, 4, 5, 6, 8, and 9.

• Permanent obturation of the root canal following removal of infected or necrotic pulp and placement of intracanal dressings.

ENDOSEAL MTA is an endodontic sealer based on MTA, providing a biocompatible and effective root canal filling. It is premixed and pre-loaded in a syringe, which allows a complete filling of the entire root canal including accessory and lateral canals. The product is eugenol-free and will not impede adhesion inside the root canal.

Below is a summary of the acceptance criteria and study information for the Endoseal MTA device, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size and Data Provenance

The provided text does not specify the sample sizes used for the test set in any of the performance or biocompatibility tests.
The data provenance is from non-clinical testing conducted by MARUCHI, as presented in the 510(k) submission. The country of origin of data is implicitly the Republic of Korea, where MARUCHI is located. The studies are retrospective in the sense that they are summary test results, not prospective trials.

3. Number of Experts and Qualifications for Ground Truth

This information is not applicable to this type of device submission. The "ground truth" for this medical device (a root canal filling resin) is established by adherence to recognized international standards (ISO) for material properties and biocompatibility, as well as by comparison to legally marketed predicate devices. The performance is assessed through laboratory testing, not through expert consensus on diagnostic images or patient outcomes in the same way an AI diagnostic device would be.

4. Adjudication Method for the Test Set

This information is not applicable. Adjudication methods like 2+1 or 3+1 are typically used in clinical studies or studies involving expert review of data (e.g., imaging) where there might be disagreement in interpretations. For performance and biocompatibility testing of a material, the results are typically quantitative or qualitative based on established standard methods, and adjudication is not usually applied in this context.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

A multi-reader multi-case (MRMC) comparative effectiveness study was not conducted for this device. This type of study is relevant for diagnostic or AI-assisted devices where human readers interpret medical images or data. The Endoseal MTA is a material used in a dental procedure.

6. Standalone Performance Study

Yes, a standalone performance study was done in the sense that the device was subjected to a series of bench and biocompatibility tests without human intervention or interpretation of the material's properties by human operators with respect to its performance against the set standards. The tests were performed on the device itself to verify its physical, chemical, and biological properties.

7. Type of Ground Truth Used

The ground truth used for this device is based on established international standards (ISO 6876, ISO 10993 series) for the physical, chemical, and biological properties of root canal filling materials. The device's performance is measured against the criteria defined by these standards, and its safety and effectiveness are supported by demonstrating substantial equivalence to legally marketed predicate devices that also comply with these standards.

8. Sample Size for the Training Set

This information is not applicable. This device is a medical material, not an AI or machine learning algorithm that requires a training set. The "training set" concept is not relevant for evaluating the performance of a physical material.

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

This information is not applicable, as there is no training set for this type of device.
