The software level of concern is Moderate.

The provided document is a 510(k) summary for the EzDent-i / E2 / Prora View / Smart M Viewer software. It describes the device, its intended use, and argues for its substantial equivalence to a predicate device.

However, the document does not contain the detailed information necessary to answer all parts of your request, specifically regarding acceptance criteria, reported device performance, sample sizes, expert qualifications, adjudication methods, MRMC studies, standalone performance, or training set details.

This 510(k) submission primarily focuses on demonstrating that the updated software version (v3.4) is substantially equivalent to a previous cleared version (v3.3) by highlighting that the changes are for "user convenience and do not affect the device safety or effectiveness". It therefore does not provide a comprehensive study report with quantified performance metrics against specific acceptance criteria for diagnostic accuracy, which would typically be found in direct performance studies for devices with diagnostic claims.

Here's what can be extracted and what is missing:

1. Table of Acceptance Criteria and Reported Device Performance

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

• Sample Size for Test Set: Not specified.
• Data Provenance (e.g., country of origin of the data, retrospective or prospective): Not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

• Number of Experts: Not specified.
• Qualifications of Experts: Not specified.
  • The Indications for Use state the device is "meant to be used by trained medical professionals such as radiologist and dentist." This implies the target users, but not the experts for ground truth.

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

• Adjudication Method: Not specified.

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

• MRMC Study: No, an MRMC comparative effectiveness study is not mentioned. The device is described as "dental imaging software that is intended to provide diagnostic tools" and its results are "dependent on the interpretation of trained and licensed radiologists, clinicians and referring physicians as an adjunctive to standard radiology practices for diagnosis." This suggests it is a viewing and processing tool, not a diagnostic AI that would typically undergo an MRMC study to show improvement in human reader performance.

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

• Standalone Performance Study: No, a standalone performance study is not described. Given the device's function as an image management and processing system used "as an adjunctive to standard radiology practices for diagnosis," it is not presented as an AI algorithm providing standalone diagnoses.

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

• Type of Ground Truth: Not specified, as specific performance tests against diagnostic ground truth are not detailed. The performance data section broadly mentions "SW verification/validation and the measurement accuracy test were conducted," implying functional and technical testing rather than a clinical performance study with established ground truth for diagnostic accuracy.

8. The sample size for the training set

• Sample Size for Training Set: Not applicable/Not specified. The document describes software with various image processing and management features, rather than a machine learning or AI algorithm that would require a distinct "training set."

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

• Ground Truth for Training Set: Not applicable/Not specified, as no training set for a machine learning model is mentioned.

Summary of what the document implies about performance testing:

The "Performance Data" section states: "SW verification/validation and the measurement accuracy test were conducted to establish the performance, functionality and reliability characteristics of the modified devices. The device passed all of the tests based on pre-determined Pass/Fail criteria."

This indicates that Ewoosoft performed internal validation testing to ensure the software met its specified functional and technical requirements (e.g., correct image display, accurate measurements for linear distance and angle, proper functioning of new features like "Image Share" and "IO sensor image Preview"). However, these are not detailed clinical performance metrics for diagnostic efficacy or accuracy that would typically be associated with AI-driven diagnostic devices. Since the device is presented as substantially equivalent to a predicate device for managing and processing images, the focus of the 510(k) is on the safety and effectiveness of the software updates rather than demonstrating novel diagnostic performance.

This document describes a 510(k) premarket notification for the EzDent-i / E2 / ProraView/ Smart M Viewer, a dental imaging software. The submission aims to demonstrate substantial equivalence to a previously cleared version of the same software (EzDent-i / E2 / Prora View / Smart M Viewer v.3.2, K211795).

Based on the provided information, the following can be extracted:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria or detailed device performance metrics in a pass/fail format. Instead, it relies on a statement that "The device passed all of the tests based on pre-determined Pass/Fail criteria." The study's focus was on demonstrating that modifications made to the software "do not raise the questions of safety or effectiveness" and that the newer version is substantially equivalent to the predicate device.

The reported device performance, in terms of meeting criteria, is implicitly described as:

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

The document states that "SW verification/validation and the measurement accuracy test were conducted." However, it does not provide any details regarding:

• The specific sample size (e.g., number of images, number of cases) used for the test set.
• The data provenance (e.g., country of origin, retrospective or prospective nature of the data).

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

This information is not provided in the document. The document mentions that the software's diagnostic tools are "meant to be used by trained medical professionals such as radiologist and dentist" and that "Results produced by the software's diagnostic, treatment planning and simulation tools are dependent on the interpretation of trained and licensed radiologists, clinicians and referring physicians as an adjunctive to standard radiology practices for diagnosis." However, it does not specify how ground truth was established for the performance testing.

4. Adjudication Method for the Test Set

The document does not specify any adjudication method (e.g., 2+1, 3+1, none) used for establishing ground truth for the test set.

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

An MRMC comparative effectiveness study was not performed or reported in this submission. The study focuses on demonstrating substantial equivalence of the modified software version to its predicate through software verification/validation and measurement accuracy testing, rather than evaluating human reader performance with or without AI assistance.

6. Standalone (Algorithm Only) Performance Study

A standalone performance study focused on the algorithm's performance without human-in-the-loop interaction was performed implicitly through the "SW verification/validation and the measurement accuracy test." These tests are typically designed to assess the software's intrinsic functionalities and accuracy parameters independently. The submission indicates that these tests were conducted and passed. However, specific metrics (e.g., sensitivity, specificity, AUC) for diagnostic capabilities are not provided, as the device is characterized as a "medical image management and processing system" with "diagnostic tools," meaning it is an adjunctive tool for image interpretation by clinicians.

7. Type of Ground Truth Used

The type of ground truth used for the "SW verification/validation and the measurement accuracy test" is not explicitly stated. Given the nature of a "medical image management and processing system" and its function of enabling trained professionals to "view and interpret" images and provide "diagnostic tools," the ground truth for measurement accuracy tests would likely involve precisely measured objects or features within reference images. For software functionality, it would involve confirming that features operate as intended based on predefined specifications. Pathology or outcomes data are not mentioned as being used for ground truth.

8. Sample Size for the Training Set

The document does not provide any information about a training set or its sample size. This submission describes an updated version of existing software, and the evaluation focuses on comparing it to a predicate device rather than on the development and training of a new AI algorithm.

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

As no training set is mentioned, information on how its ground truth was established is not applicable/not provided in this document.
