The provided text is a 510(k) summary for the EzDent-i / E2 / Prora View dental imaging software. Based on the information given, here's an analysis addressing your questions:

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

The document states:

• "Verification, validation and testing activities 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."
• "The subject device and the unmodified device are substantially equivalent, having the same indications for use and functionalities like operation software, computer platform, picture archiving and communication format, image format, image processing features, windowing. image edit, measurements and manipulation."
• "The differences are that the subject device has changes in PC System Requirement Information Change, Settings upgrade (Annotation, Privacy Policy, adding Help Document, VIEWER tab upgrade (Export Image with Overlay, Saving as IO Sensor Image) and adding SERVICE tab. These differences are not significant since they are additional features for user convenience and do not raise the questions of safety or effectiveness."

Crucially, this 510(k) summary does not provide a specific table of quantitative acceptance criteria or detailed performance metrics. The core of this submission is to demonstrate substantial equivalence to a previously cleared device (EzDent-i / E2 / ProraView, K172364). The "performance data" section only states that testing was done and passed pre-determined criteria, but it does not specify what those criteria were (e.g., minimum accuracy, sensitivity, specificity for a diagnostic task). The changes appear to be primarily related to software features, user interface, and system compatibility, rather than fundamental diagnostic algorithm performance.

Therefore, a table of acceptance criteria and reported device performance specific to diagnostic accuracy (e.g., AUC, sensitivity, specificity) cannot be extracted from this document because it's not a de novo submission or a significant change that would necessitate such detailed performance validation for diagnostic claims.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

The document does not specify the sample size used for any test set or the provenance of the data (country of origin, retrospective/prospective). Given that the submission focuses on substantial equivalence based on feature updates rather than new diagnostic claims, it's unlikely a large-scale diagnostic performance study with specific sample sizes was conducted. The testing likely focused on functional verification and validation of the new software features.

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 information is not provided in the document. Since the submission is not focused on validating a new diagnostic algorithm's performance against ground truth, there's no mention of expert-established ground truth or expert qualifications used for such a test.

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

This information is not provided in the document.

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

No such study (MRMC or otherwise demonstrating human reader improvement with AI assistance) is mentioned or implied in this 510(k) summary. The device's purpose is "to provide diagnostic tools" and is "meant to be used by trained medical professionals such as radiologist and dentist" for viewing and interpreting images. It is not described as an AI-powered diagnostic aid that assists human readers.

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

This document does not indicate that a standalone algorithm performance study was conducted. The device is described as software that provides tools for human interpretation, not an autonomous diagnostic algorithm.

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

Since the document does not detail a diagnostic performance study, the type of ground truth used is not specified.

8. The sample size for the training set

This information is not provided. The device is described as "dental imaging software," and it's unclear if it even employs machine learning/AI models that would require a "training set" in the conventional sense for diagnostic tasks. The changes described are primarily software features and compatibility updates.

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

Not applicable, as no information about a training set or its ground truth establishment is provided.

Summary of what's provided for acceptance criteria and proof of meeting them:

The 510(k) submission for EzDent-i / E2 / Prora View (K190087) focuses on demonstrating substantial equivalence to its predicate device (K172364) following software updates. The acceptance criteria described are primarily functional:

• The device retains the same indications for use.
• The device maintains the same functionalities as the predicate, including image acquisition, viewing, saving, loading DICOM files, image processing features (brightness, contrast, measurement), and simulation tools.
• New features (PC system requirement changes, settings upgrades, viewer tab upgrades, service tab) are deemed "additional features for user convenience" and do not raise new questions of safety or effectiveness.
• "Verification, validation and testing activities 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."

The proof of meeting those criteria is presented as the statement that "the device passed all of the tests based on pre-determined Pass/Fail criteria" and the FDA's ultimate determination of substantial equivalence. The document does not disclose the specific quantitative criteria or the detailed results of those tests (e.g., specific error rates, precision, or recall for any diagnostic task). This is typical for a 510(k) submission based on substantial equivalence for software updates, where the primary concern is that the changes do not adversely affect existing validated functionality and safety.

OrthoVision is a 2D orthodontic analysis and simulation program created by EWOOSOFT. OrthoVision manages patient information and images during orthodontic analysis. This software also assists in orthodontic treatment by providing accurate image analysis, growth forecasts, profilograms, superimpositions, and VTO/STO simulations. The analyzed results are saved in chart format so that you can easily store and track treatment and records of each patient.

The provided text is a 510(k) summary for the OrthoVision software. It asserts substantial equivalence to a previous version of the same device. As such, it does not contain the detailed study information typically found in a De Novo or full PMA submission where a new device's performance is rigorously tested against acceptance criteria.

The document states that "Verification, validation and testing activities 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." However, it does not specify what those acceptance criteria were, what tests were conducted, or the results of those tests in a quantifiable manner.

Therefore, the requested information, specifically acceptance criteria and a study proving the device meets them, is not present in the provided text.

Here's a breakdown of the specific points missing:

1. A table of acceptance criteria and the reported device performance: This is not provided. The document only states that tests were conducted and passed.

These tools are available to view and interpret a series of DICOM compliant dental radiology images and are meant to be used by trained medical professionals such as radiologist and dentist.

EzDent-i is intended for use as software to acquire, view, save 2D image files, and load DICOM project files from panorama, cephalometric, and intra-oral imaging equipment.

EzDent-i is a device that provides various features to acquire, transfer, edit, display, store, and perform digital processing of medical images. EzDent-i is a patient & image management software specifically for digital dental radiography. It also provides server/client model so that the users upload and download clinical diagnostic images and patient information from any workstations in the network environment.

EzDent-i supports general image formats such as JPG and BMP for 2D image viewing as well as DICOM format. For 3D image management, it provides uploading and downloading support for dental CT Images in DICOM format. It interfaces with a 3D imaging software made by our company, the Ez3D-i (K131616, K150761, K161246) but the EzDent-i itself does not view, transfer or process 3D radiographs.

EzDent-i supports the acquisition of dental images by interfacing with OpenCV library to import the intra-oral camera images. It also supports the acquisition of CT/Panoramic/Cephalo/Intra-Oral Sensor images by interfacing with X-ray capture software.

• Print function supporting various viewing output format

The provided text describes a 510(k) premarket notification for a dental imaging software called EzDent-i (also referred to as E2 and ProraView). The primary purpose of this submission is to demonstrate substantial equivalence to a legally marketed predicate device. As such, the document focuses on comparing the new device to the predicate device rather than detailing specific performance studies with acceptance criteria for diagnostic accuracy.

Therefore, based on the provided text, I cannot provide a table of acceptance criteria and reported device performance related to diagnostic accuracy because such information is not present. The document focuses on performance related to functionality and reliability of the software.

Here's an analysis addressing the other points based only on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

As noted above, the provided text does not contain specific acceptance criteria or reported device performance metrics related to diagnostic accuracy (e.g., sensitivity, specificity, AUC) for the EzDent-i software. The document states:

"Verification, validation and testing activities 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 internal performance tests were conducted for functionality and reliability, and the device met its own pre-determined pass/fail criteria for these aspects. However, further details on these criteria or the results are not provided.

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

The document does not specify any sample size used for a test set (in the context of evaluating diagnostic performance) or the data provenance (e.g., country of origin, retrospective/prospective). The testing mentioned refers to "performance, functionality and reliability characteristics" of the software itself.

3. Number of Experts Used to Establish Ground Truth and Qualifications

The document does not mention the use of experts to establish a ground truth for any diagnostic performance test set. The software is described as providing "diagnostic tools," but its own diagnostic accuracy is not explicitly evaluated in the provided text.

4. Adjudication Method

No adjudication method is mentioned, as there is no described diagnostic performance study involving human readers or expert panels.

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

A multi-reader multi-case (MRMC) comparative effectiveness study is not mentioned. The document focuses on the software's features and its substantial equivalence to a predicate device, not on how human readers perform with or without AI assistance.

6. Standalone (Algorithm Only) Performance Study

A standalone performance study for the algorithm's diagnostic accuracy is not mentioned. The "performance data" refers to the verification, validation, and testing of the software's functionality and reliability.

7. Type of Ground Truth Used

No type of ground truth (e.g., expert consensus, pathology, outcomes data) is mentioned, as no diagnostic performance study is described. The "ground truth" for the software's own functionality and reliability would relate to its adherence to design specifications.

8. Sample Size for the Training Set

No sample size for a training set (relevant for machine learning algorithms) is mentioned. The description of the device's technological characteristics does not indicate the use of AI/machine learning that requires a training set in the typical sense. It describes features like "image processing functions including adjustment of brightness and contrast" and "measurement function of length and angle," which are generally rule-based or conventional image processing techniques, not typically requiring large training datasets for their core function.

9. How Ground Truth for Training Set Was Established

Since no training set is mentioned, the method for establishing its ground truth is also not described.

Here's an analysis of the provided text regarding the acceptance criteria and study for Ez3D-i / E3, specifically focusing on the aspects requested:

Device: Ez3D-i / E3 (Dental imaging software)

1. Table of Acceptance Criteria and Reported Device Performance

The provided 510(k) summary does not explicitly list specific quantitative acceptance criteria or detailed reported device performance metrics in a table format. Instead, it makes a general statement about the testing performed.

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

The document does not specify the sample size used for the test set. It also does not mention 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

The document does not provide any information about the number of experts used to establish ground truth or their qualifications.

4. Adjudication Method for the Test Set

The document does not mention any adjudication method used for the test set.

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

The document does not indicate that an MRMC comparative effectiveness study was performed. There is no mention of human readers, AI assistance, or effect sizes related to human performance improvement.

6. If Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

The document describes Ez3D-i as "dental imaging software that is intended to provide diagnostic tools...These tools are available to view and interpret... and are meant to be used by trained medical professionals such as radiologist and dentist." It also states "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."

This strongly suggests that the device is intended for human-in-the-loop use, where the software provides tools, and the medical professional performs the interpretation and diagnosis. The document does not explicitly describe a standalone (algorithm only) performance evaluation.

7. The Type of Ground Truth Used

The document does not explicitly state the type of ground truth used. Given the nature of the device as a viewing and analysis tool for imaging, it is highly likely that the "ground truth" for its verification and validation would involve:

• Known image datasets: Using existing DICOM image sets where the anatomical structures, pathologies, or features are already well-established (e.g., through prior consensus reads, surgical confirmation, or other clinical information).
• Software functionality validation: Testing that the software accurately performs its stated functions (e.g., MPR, 3D visualization, measurements, implant simulation) according to expected outputs, rather than a clinical ground truth for disease detection.

8. The Sample Size for the Training Set

The document does not provide any information about a training set or its sample size. This is consistent with the device being primarily a viewing and analysis tool rather than a machine learning-based diagnostic algorithm that requires explicit training data.

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

Since no training set is mentioned, there is no information on how its ground truth might have been established.
