No
The description focuses on the hardware (CMOS sensor, USB connection) and basic image capture functionality. There is no mention of AI, ML, or advanced image processing beyond standard digital image acquisition. The software is mentioned as being cleared separately and is likely standard imaging software.
No.
The device is used for capturing diagnostic x-ray images and detecting anomalies, which is a diagnostic purpose, not a therapeutic one. It facilitates diagnosis but does not provide treatment.
Yes
This device is a diagnostic device because its "Intended Use" explicitly states it's for "capturing of digital diagnostic x-ray images" and its "Device Description" says it's "used in the detection and diagnosis of anomalies in dental anatomy."
No
The device description clearly states it is a physical CMOS sensor with image capture components, a USB plug, and internal hardware like a scintillator. While it uses software, it is fundamentally a hardware device.
No, 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 Tuxedo Digital Dental Sensor is an in vivo device. It is placed inside the patient's mouth to capture images generated by an external x-ray source. It does not analyze samples taken from the patient.
- Intended Use: The intended use is to capture digital diagnostic x-ray images on a patient for evaluation. This is a direct interaction with the patient's body, not an analysis of a sample.
The device is a medical imaging device used for diagnostic purposes, but it falls under the category of radiological imaging devices, not in vitro diagnostics.
N/A
Intended Use / Indications for Use
The Tuxedo Digital Dental Sensor is a CMOS sensor for the capturing of digital diagnostic x-ray images on a patient for evaluation by an appropriately trained oral healthcare professional. The Tuxedo sensor itself is a single piece comprised of the image capture components on one end, with a USB 2.0 plug on the other end. The sensor is designed to be used in conjunction with a disposable, single-use hygienic sheath as well as a positioning device to allow for proper alignment within the patient's mouth. Images are acquired with the Tuxedo sensor by plugging it into a USB port and properly placing it in the patient's mouth, while an operator exposes radiation toward the sensor from an approved intraoral x-ray generator.

Device Description
The TUXEDO Dental Digital Sensor is used in the detection and diagnosis of anomalies in dental anatomy, as well as for the evaluation of performed treatment in dental care. The primary use is by general dental practitioners to detect the presence and extent of carious legions in the dentin and enamel of a tooth. Two different sized sensors (size 1 and size 2) are utilized to image different anatomy and different patient sizes. The TUXEDO Dental Digital Sensor functions by being placed in a patient's mouth lingually by a licensed dental practitioner, and is designed to capture collimated radiation which is converted into a digital image for viewing by a licensed dental practitioner. The capturing of the radiation is done within the TUXEDO sensor casing which contains a scintillator used to convert the radiation into visible light, and this visible light is immediately captured by the internal CMOS sensor. The digital image is transferred to a computer via USB 2.0 and can be viewed in most common imaging software programs, including LED Imaging Software. A software driver is available from LED Dental which will allow the TUXEDO sensor to be used in these software programs. The software supplied with the Tuxedo Digital Dental Sensor was cleared separately by FDA by Apteryx, Inc. The sensor is intended to be used with a disposable barrier sheath that should be replaced between patients. This is to reduce cross contamination between patients. The sensor is also sealed in a way that the portion of the device that is placed in the patient's mouth can be sterilized with liquid without the device being damaged.

- Performance Testing: Successful standards testing was done according to the following: Radiated Emission IEC60601-1-2: 2007, including Radiated Immunity EN61000-4-3, and Electrostatic Discharge (ESD) EN61000-4-2.
Dielectric strength and PATIENT LEAKAGE CURRENT and Temperature of APPLIED PARTS: IEC60601-1:2005.

Imaging performance tests were conducted according to IEC6220-1, Characteristics of digital X-ray imaging devices - Part 1: Determination of the detective quantum efficiency.
Other testing: The stability of sensitivity, dark output and offset value.
Mechanical Strength Testing: Bending and Pulling Test of Cable
Other Reliability Test Reporting: Dropping, Alcohol Dipping, Air leakage, Mechanical Strength of APPLIED PART, and Transport testing.
Although the device does not directly contact the patient, biomedical conformity was evaluated according to food utensil safety requirements of Japan.
We also conducted a risk analysis according to the recommendations of IEC 14971, Application of Risk Management to Medical Devices. There are three broad categories of risk: Broadly Acceptable Region; Marginal; countermeasure required to reduce risk to acceptable level (ALARP) and Intolerable; countermeasure required to reduce risk to acceptable level. After applying countermeasures, all risks were reduced to the BA (broadly acceptable) category. The application of the standards testing (above) was the main method of risk reduction, as well as relying on the use of FDA cleared components such as the sanitary barriers and the software. The sensor has been previously cleared as well.

- Clinical Testing: Clinical images were provided using a Phantom equivalent to a 51 year old male. Phantom Utilized for Image Capture:
DXTTR III Dental X-Ray Phantom (Human Skull): A training phantom. With real skull and teeth with silicone face etc.
- Clinical Testing: Clinical images were provided using a Phantom equivalent to a 51 year old male. Phantom Utilized for Image Capture:
Intra-Oral X-Ray Generator Utilized: Gendex Expert DC
These images were not necessary to establish substantial equivalence based on the modifications to the device (note CMOS detector that is very similar to the predicate dental detector Rio), but they provide further evidence in addition to the laboratory performance data to show that the complete system works as intended. All images acquired demonstrated excellent diagnostic imaging quality on both the size #1 and the size #2 sensor. The sensors demonstrated a good latitude response from variations in generator settings. Contrast and spatial resolution on all images were good to excellent on all images acquired.
-
- Conclusion as to Substantial Equivalence: In accordance with the federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification. LED Dental concludes that the Tuxedo Digital Dental Sensor is safe and effective to perform its intended use as well as substantially equivalent to the predicate device.
