Intended Use

Ai Ray Dental X-Ray Device is an extraoral diagnostic dental X-ray source to produce X-ray images using intraoral image receptors. It is indicated for use by a dental technician for both adult and pediatric patients.

Device Description

Ai Ray Dental X-Ray Device is a super capacitor-operated, portable dental X-ray source designed for handheld operation. It is designed to produce diagnostic quality X-rays images utilizing either film or digital imaging techniques. The Portable Dental X-ray Device is designed for use in a dental office. It can also be used in other similar environments (orthodontic office, general practitioner's office, hospital ward, etc.) where appropriate safeguards are implemented. The device uses a rechargeable supercapacitor to allow for the use of the Portable Dental X-ray Device where transportation or use of other x-ray devices might be prohibitive due to the other device's size and/or lack of mobility.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "an extraoral diagnostic dental X-ray source to produce X-ray images." The "Device Description" also mentions it is "designed to produce diagnostic quality X-rays images."

SaMD (Software as a Medical Device)

The device description explicitly states it is a "portable dental X-ray source designed for handheld operation" and uses a "rechargeable supercapacitor," indicating it is a hardware device that produces X-rays, not a software-only device.

IVD (In Vitro Diagnostic)

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

IVD devices are used to examine specimens obtained from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or treatment.
This device is an X-ray source used to produce images of the teeth, jaw, and other oral structures within the patient's body. It is a diagnostic imaging device, not an in vitro diagnostic device.

The description clearly states its purpose is to produce X-ray images using intraoral image receptors, which is a form of medical imaging performed directly on the patient.

Dear Charles Mack:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.

For comprehensive regulatory information about medical devices and radiation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/medicaldevices/device-advice-comprehensive-regulatory-assistance) and CDRH Learn (https://www.fda.gov/training-and-continuing-education/cdrh-learn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic. See the DICE website (https://www.fda.gov/medical-device-advice-comprehensive-regulatoryassistance/contact-us-division-industry-and-consumer-education-dice) for more information or contact DICE by email (DICE@fda.hhs.gov) or phone (1-800-638-2041 or 301-796-7100).

Device Description:

The differences between the proposed Ai Ray Dental X-Ray Device and the predicate EzRay Air Portable, VEX-P300 (K200182) are as follows:

The opening key is positioned differently, EzRay Air Portable at the bottom and Ai Ray at the top.
The structural shapes of the two devices are different.

Principles of Operation

The equipment acquires images by emitting X-rays continuously on a human tooth. X-rays are emitted when high voltage is supplied to the X-ray tube assembly, which frees electrons from the cathode. They hit the anode to produce X-rays.

Comparison of Technological Characteristics with the Predicate Device

Differences Discussion:

Note1 The physical shape/size difference has no impact on safety and performance. Both devices conform to the same safety and performance standards.

Note 2 The distance difference has no impact on safety and performance. Both devices conform to the same safety and performance standards.

Note 3 The difference has no impact on safety and performance. Both devices conform to the same safety and performance standards.

Note 4 The size of the backscattering shield is different due to different device shapes. The radiation leakage value of the device with a backscattering shield after testing meets the requirements of the FDA. Security and performance are not affected.

Note 5 Although the battery specifications are different, they conform to the same requirement of IEC 62133 for the rechargeable battery. The differences do not raise issues of safety and effectiveness.

Note 6 Both devices conform to the same requirement of federal standard requirements. The performance test demonstrated that the difference doesn't raise safety and effectiveness issues.

Note 7 Although the X-ray tube's specifications are not identical and conform to the same performance standards IEC 60601-2-65, The performance test demonstrated the difference doesn't raise safety and effectiveness issues.

Note 8 Although the X-ray tube's specifications are not identical, and they conform to the same performance standards IEC 60601-2-65. The performance test demonstrated that the difference doesn't raise safety and effectiveness issues.
