No
The summary describes a standard extra-oral dental X-ray system and does not mention any AI or ML capabilities for image processing, analysis, or other functions.
No.
The device is described as an extra-oral x-ray system used for producing diagnostic images of dental structures, which is a diagnostic function, not a therapeutic one.
Yes
The device is described as producing images for "diagnostic dental radiographic examination and diagnosis of teeth, jaw, and other oral structures," and is used for "dental diagnosis such as dental caries, periodontal diseases, dental root fracture, and other oral and dental pathologies." This clearly indicates its role in the diagnostic process.
No
The device description explicitly states that DVAS is an "extra-oral source x-ray system" and "standard X-ray equipment," indicating it is a hardware device that emits X-rays.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Definition of IVD: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The DVAS is an extra-oral x-ray system. It uses radiation to create images of internal structures (teeth, jaw, etc.) within the body. It does not analyze samples taken from the body.
- Intended Use: The intended use is for producing diagnostic dental radiographic examinations and diagnosis using intra-oral image receptors. This involves imaging the patient directly, not analyzing a sample from the patient.
Therefore, the DVAS falls under the category of a medical imaging device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use

Device Description
DVAS, the extra-oral source x-ray system for dentistry is the standard X-ray equipment used to acquire intraoral images of patients during dental diagnosis such as dental caries, periodontal diseases, dental root fracture, and other oral and dental pathologies. DVAS is used to provide anatomic X-ray images of a patient at hospitals or dental clinics using a cone for X-ray exposure.
The doctor or dentist can check the acquired X-ray images with chemical films or a PC monitor.
DVAS can be used Digital I/O Sensor, Image plate (CR), Film as a Image receptor. The image receptors are not part of this submission. And the minimum integration requirements for intra-oral detectors when used with this device are:
Pixel Size: ≤ 40 μm

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
DVAS have been successfully compeleted verification and validation testing per GENORAY quality system as well engineering bench testing in support of successfully completed verification and validation testing per GENORAY quality system and this submission.
The system has been tested and is compliant with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3. IEC 60601-1-6. IEC 60601-2-65. IEC 62366. Also. DVAS complies with all applicable 21 CFR performance standards (21 CFR 1020.30, 21 CFR 1020.31).
And Software was validated according to the FDA Guidance "Guidance for the Content of Premarket Submissions for Software Contained in Medical devices", FDA Guidance "Guidance for the content of premarket submissions for management of cyber security". Results demonstrated that all executed verification tests were passed.
DVAS can be used not only in adults but also In the pediatric population, and therefore the system has reflected pediatric information in the labeling according to the FDA Guidance "Pediatric Information for X-ray Imaging Device Premarket Notifications," dated November 28, 2017".
Non-clinical validation testing has been performed to validate that DVAS conform to the intended use, claims, user needs, effectiveness of safety measures and instructions for use.
As a results, all test results were satisfactory and the result of bench tests indicates that the new device is as safe and effective as the predicate device.

8. Safety, EMC and Performance data comparison to Predicate [21 CFR 807.92(b)]
DVAS have been successfully compeleted verification and validation testing per GENORAY quality system as well engineering bench testing in support of successfully completed verification and validation testing per GENORAY quality system and this submission.
The system has been tested and is compliant with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-3. IEC 60601-1-6. IEC 60601-2-65. IEC 62366. Also. DVAS complies with all applicable 21 CFR performance standards (21 CFR 1020.30, 21 CFR 1020.31)
And Software was validated according to the FDA Guidance "Guidance for the Content of Premarket Submissions for Software Contained in Medical devices", FDA Guidance "Guidance for the content of premarket submissions for management of cyber security". Results demonstrated that all executed verification tests were passed.
DVAS can be used not only in adults but also In the pediatric population, and therefore the system has reflected pediatric information in the labeling according to the FDA Guidance "Pediatric Information for X-ray Imaging Device Premarket Notifications," dated November 28, 2017"
Non-clinical validation testing has been performed to validate that DVAS conform to the intended use, claims, user needs, effectiveness of safety measures and instructions for use.
As a results, all test results were satisfactory and the result of bench tests indicates that the new device is as safe and effective as the predicate device.
9. Conclusion
In reference to the comparison information provided in the substantial equivalence chart, and the most of functions and electronic features are similar with the predicate device. We believe that the DVAS are safe and effective as predicate device, and have no new indication for use. Therefore, DVAS are substantially equivalent to predicate device.
