The summary describes a digital dental x-ray sensor and image processing system, but there is no mention of AI, ML, or related concepts in the intended use, device description, performance studies, or any other section. The focus is on the sensor technology and image acquisition speed.
No
The device is described as collecting and converting dental x-ray photons for diagnostic use by dentists, not for treatment or therapy.
Yes
The "Intended Use / Indications for Use" section states that the electronic impulses "may be stored, viewed and manipulated for diagnostic use by dentists," directly indicating a diagnostic purpose.
No
The device description explicitly states it is a "bendable sensor that is connected to a computer," indicating a hardware component (the sensor) is integral to the device's function.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD definition: 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 EzSensor Soft, EzSensor Soft i, and EzSensor Bio i are digital dental intraoral sensors. Their function is to capture dental x-ray images directly from within the patient's mouth.
- No sample analysis: The device does not analyze any biological samples taken from the patient. It converts physical x-ray photons into digital data for imaging purposes.
Therefore, while it's a medical device used for diagnosis, it falls under the category of medical imaging devices, not In Vitro Diagnostics.

Device Description
EzSensor Soft, EzSensor Soft i, EzSensor Bio i are digital dental intraoral sensors which acquire digital intra oral images. Direct digital systems acquire images with a bendable sensor that is connected to a computer to produce an image almost instantaneously following exposure. The primary advantage of direct sensor systems is the image acquisition speed. For patient comfort, the ergonomic design is based on human intraoral anatomy.
- Excellent image quality based on advanced CMOS technology
- · Sensor's ergonomic shape is more comfortable for the human oral structure
- · Lower dose exposure (compared to film sensor)
- Enhanced durability

This device is operated using viewer software. With the identical hardware configuration, the intraoral sensor model name is distinguished by the type and version of image viewing software available. The software functions include the patient information management, image capture, and viewer for captured images. Both EzDent-i 1.0 and 2.0 versions have 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 EzDent-i 2.0 (K150747) has additional features such as "Hide the patient information", "Export to acquisition information", "Create New Report" and "Print Setting".
In addition, a new sensor size 1.5 is available to the existing sensor sizes 1.0 and 2.0 of the predicate device.
These differences do not raise the questions of safety or effectiveness. Based on the laboratory testing results submitted in this 510K, we conclude that the subject device is substantially equivalent to the predicate device.
6. Summary of Performance Testing
The intended use, application and detector type of EzSensor Soft i, EzSensor Soft i, EzSensor Bio, EzSensor Bio i are identical to the predicate device. Both the subject and predicate device use the same amorphous silicon alley and materials for fluorescent as the sensing means. The performance test result indicates that the EzSensor Soft, EzSensor Soft i, EzSensor Bio, EzSensor Bio i detector performed equally the predicated device; EzSensor Soft [Alternative name : EzSensor Bio] and no additional safety risk is identified in the bench test: Non-clinical report.
Non-clinical according to FDA Guidance "Guidance for the Submissions of 510(k)'s for Solid State X-
8
ray Imaging Devices" was performed.
The DQE, MTF and linear response to X-ray exposure test demonstrated that the subject sensor performed equivalently compared to the predicate device with the same dynamic range.
Electrical, mechanical, environmental safety and performance testing were performed according to standard IEC 60601-1: 2005 + CORR.1(2006) + CORR(2007) (Medical electrical equipment Part 1:General requirements for basic safety and essential performance). EMC testing was conducted in accordance with standard IEC 60601-1-2:2007.
7. Conclusions
In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification. Rayence Co., Ltd. concludes that EzSensor Soft, EzSensor Soft i, EzSensor Bio, EzSensor Bio i is safe and effective and substantially equivalent to predicate device as described herein.
