Intended Use

The Intraoral Dental Digital Imaging Sensor is aimed at the acquisition of intra-oral medical images from teeth, jaw and oral structure, only for exclusive dental use and must be handled by trained and qualified health professionals.

Device Description

This Intraoral Dental Digital Imaging Sensor employs CMOS (Complementary Metal-Oxide-Semiconductor), protective optical fiber and scintillator. There are three names proposed for this device: EAGLE S/ SAEVO SLIM/D700 SLIM. The three models are all identical except for the name. This sensor was developed to obtain a high-quality x-ray image from the human arch and its structures. The acquisition process is made by positioning the sensor inside the mouth, behind the structure you want to perform the exam. The structure must be exposed to an x-ray dose using an external source. Once exposed, the sensor performs a conversion of the x-ray photons into a digital sign and transfers it to a computer through USB connection (Universal Serial Bus). The device performs the acquisition by positioning the sensor inside of the patient's mouth, behind the structure to be examined. The structure should be exposed to a dose of x-rays, using an external source. Once exposed, the sensor performs a conversion of the x-ray photons into a digital signal and then transfers it to a computer via a Universal Serial Bus (USB) connection. The x-ray generator (an integral part of a complete dental x-ray system) is not part of the device.

AI/ML Overview

The provided text describes the marketing submission for an Intraoral Dental Digital Imaging Sensor (Eagle S/Saevo Slim/D700 Slim) and its claim of substantial equivalence to a predicate device. However, it does not contain detailed acceptance criteria or a comprehensive study demonstrating performance against specific numerical or qualitative endpoints. The document primarily focuses on non-clinical testing (safety, EMC, biocompatibility) and a general statement about clinical images.

Here's an analysis of what information is available and what is missing, structured according to your request:

Acceptance Criteria and Reported Device Performance

The document does not explicitly define acceptance criteria as pass/fail thresholds for specific performance metrics. Instead, it presents a comparison table and discusses general improvements over the predicate device.

Acceptance Criteria (Implicit/Derived)Reported Device Performance (vs. Predicate)
Resolution (Line pairs/mm)25 lp/mm (Predicate: 15 lp/mm)
Pixel Size20 µm (Predicate: 33 µm)
Number of Pixels (Size 1)1000 x 1500 (Predicate: 600 x 900)
Number of Pixels (Size 2)1300 x 1800 (Predicate: 800 x 1000)
MTF (Modulation Transfer Function)>70% @ 1.47 lp/mm (at RQA5) (Predicate: Not specified)
DQE (Detective Quantum Efficiency)>61.3% @ 0 lp/mm (at RQA5) (Predicate: Not specified)
Contrast12 bits (Same as Predicate)
Gray Level4096 (Same as Predicate)
Clinical AcceptabilityImages are of "good quality, clinically acceptable, and better than the predicate images."

Study Details

  1. Sample size used for the test set and the data provenance:

    • Sample Size: Not explicitly stated for the "clinical images" or "submitted intra-oral radiographs."
    • Data Provenance: Not specified (e.g., country of origin, retrospective or prospective). The document only mentions "submitted intra-oral radiographs" and "adequate clinical images."
  2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

    • Number of Experts: One expert was mentioned for the image quality analysis.
    • Qualifications: "USA Board Certified Radiologist." No mention of years of experience.
  3. Adjudication method for the test set:

    • Adjudication Method: Not specified. It mentions a single "USA Board Certified Radiologist" performed an "image quality analysis" comparing the predicate to the new device. This suggests a sole expert review rather than a multi-reader adjudication process (e.g., 2+1 or 3+1).
  4. 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. The device is an imaging sensor, not an AI-assisted diagnostic tool for humans, so an MRMC study related to AI assistance for human readers is not relevant in this context. The clinical evaluation mentioned focused on inherent image quality of the sensor itself.
  5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

    • Standalone Performance: Yes, in the sense that the sensor's technical performance (resolution, MTF, DQE) was evaluated through bench testing, which is an algorithm/device-only evaluation. The "adequate clinical images" and radiologist review also reflect the standalone performance of the imaging sensor.
  6. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

    • Ground Truth (for image quality): Expert opinion/comparison. The "USA Board Certified Radiologist" compared images from the predicate and the new device. For the technical metrics (MTF, DQE, resolution), these are physical measurements rather than clinical ground truth established by pathology or outcomes.
  7. The sample size for the training set:

    • Sample Size for Training Set: Not applicable. This document describes an imaging sensor, not a machine learning or AI algorithm that requires a training set.
  8. How the ground truth for the training set was established:

    • Ground Truth for Training Set: Not applicable (as above).

4. Description:

This Intraoral Dental Digital Imaging Sensor employs CMOS (Complementary Metal-Oxide-Semiconductor), protective optical fiber and scintillator. There are three names proposed for this device: EAGLE S/ SAEVO SLIM/D700 SLIM. The three models are all identical except for the name. This sensor was developed to obtain a high-quality x-ray image from the human arch and its structures. The acquisition process is made by positioning the sensor inside the mouth, behind the structure you want to perform the exam. The structure must be exposed to an x-ray dose using an external source. Once exposed, the sensor performs a conversion of the x-ray photons into a digital sign and transfers it to a computer through USB connection (Universal Serial Bus). The device performs the acquisition by positioning the sensor inside of the patient's mouth, behind the structure to be examined. The structure should be exposed to a dose of x-rays, using an external source. Once exposed, the sensor performs a conversion of the x-ray photons into a digital signal and then transfers it to a computer via a Universal Serial Bus (USB) connection. The x-ray generator (an integral part of a complete dental x-ray system) is not part of the device. Device sensor sizes:

5. Indications for use:

The Intraoral dental digital imaging sensor is aimed at the acquisition of intra-oral medical images from teeth, jaw and oral structure, only for exclusive dental use and must be handled by trained and qualified health professionals.

6. Comparison with predicate device:

The predicate SunilQ Digital Radiography System is a device intended for intra-oral x-ray examinations. Two sensor sizes are available. The new device Intraoral Digital Imaging Sensor and its predicates are small digital imaging receptors that may be used in place of dental x-ray film. Predicate sensor sizes: Size 1: 20.2 x 31.1 mm, Size 2: 26.2 x 35.2 mm.

Subject device sensor sizes: Size 1: 20 x 30 mm, Size 2: 26 x 36 mm.

The images are displayed on a computer workstation. The technologies employed by the predicate and our new device are almost identical. The proposed sensors have greater resolution than the predicate via smaller pixel size and greater numbers of total pixels. The same sensor sizes are available, and the computer interface is the same (USB). Both sensors use CMOS technology. Similarities: Indications for Use, available sizes, USB interface, CMOS technology employed. Differences: New device has greater resolution via smaller pixel size and greater number of pixels. The sensor sizes are nearly identical. A comparison table follows:

7. Non-clinical Testing Performed: Safety, EMC, Biocompatibility and Performance Data:

Safety testing: Electrical, mechanical, environmental safety and performance testing according to standard ABNT NBR IEC 60601-1:2016 (IEC 60601-1:2005/AMD1:2012) was performed by a nationally certified test laboratory. Note there is no electrical contact with the patient. Required tests passed. EMC testing was done according to IEC 60601-1-2 Ed. 4.0 (2014) – Medical electrical equipment – Part 1-2: General requirements for basic safety and essential performance – Collateral standard: Electromagnetic disturbance - Requirements and tests .

Biocompatibility testing was conducted to ISO 10993-1:2020 - Biological assessment of medical devices - Part 1: Assessment and testing within a risk management process. Tests conducted: Cytotoxicity; Sensitization; Intracutaneous irritation or reactivity. These items (although there is no direct patient contact) were tested:

Product PartMaterial
Plastic CoverPolycarbonate
USB CablePolyurethane
Silicone CoverSilicone

The main patient contact material is the FDA cleared barrier sheath (K160232, Disposable Barrier Sleeves and Covers), not supplied by us. Although direct contact is unlikely inside the oral cavity, the subject dental sensor Eagle S has been tested for biocompatibility and all test results indicate compliance with biocompatibility standards. Successful software validation and risk analysis was conducted. All test results were satisfactory. Cybersecurity concerns were addressed via labeling and internal software controls. Reference: Content of Premarket Submissions for Management of Cybersecurity in Medical Devices. The subject detector Eagle S has been bench tested, and successful test results (resolution, MTF, DQE) indicate substantial equivalence to the predicate.

    1. Clinical Testing Performed: Device clinical testing has been performed, and the submitted intra-oral radiographs are deemed of diagnostic quality. Adequate clinical images are additional proof of device effectiveness, and they enforce the bench testing results that are already supporting our claim of substantial equivalence.
      We compiled a Clinical Performance Report for the Intraoral Dental Digital Imaging Sensor. The purpose was to provide analysis results and records of the requirements arising during the empirical evaluation process of the Intraoral Dental Digital Imaging Sensor clinical performance. In this report, all information related to the tests or studies required for the survey and characterization of the clinical performance based on empirical data are in their entirety. We also had an image quality analysis performed by a USA Board Certified Radiologist who compared the predicate images to the proposed device images. He concluded that the images are of good quality, clinically acceptable, and better than the predicate images.
    1. Conclusions: Our conclusions drawn from the nonclinical tests (discussed above) are that we have demonstrated that the proposed device is as safe, as effective, and performs as well as or better than the legally marketed predicate device identified according to 807.92(b)(3), 57 FR 18066, Apr. 28, 1992, as amended at 59 FR 64295, Dec. 14, 1994,According to the Federal Food, Drug and Cosmetic Law, 21 CFR Part 872. Based on the information provided in this pre-marketing notification, Alliage S/A Indústrias Médica Odontológico concludes that Intraoral Digital Imaging Sensor is safe and effective and substantially equivalent to predicated devices, as described in this document.
