No
The device description and performance studies focus on a chemical rinse and light-based visualization, with no mention of AI/ML algorithms or data processing for analysis.
No
The device is used to aid in the visualization of carious lesions, which is a diagnostic purpose, not a therapeutic one. It does not treat or cure any condition.
Yes
The device is described as aiding in the visualization of carious lesions and performance studies mention sensitivity and specificity testing, which are metrics commonly associated with diagnostic devices. The intended use is to "aid the dental professional in visualization of carious lesions," which is a diagnostic purpose.
No
The device description explicitly includes a physical oral rinse solution, a blue light source, and light orange filter accessories (including protective eyewear), which are all hardware components.
Based on the provided information, the LumiCare™ device is not an In Vitro Diagnostic (IVD).
Here's why:
- Definition of IVD: An IVD is a medical device that is used to examine specimens, such as blood, urine, or tissue, taken from the human body to provide information for diagnosis, monitoring, or screening.
- LumiCare™'s Mechanism: The LumiCare™ device is an oral rinse that is used directly in the mouth to aid in the visualization of carious lesions on tooth surfaces. It does not involve the collection and analysis of a specimen outside of the body.
- Intended Use: The intended use is to "aid the dental professional in visualization of carious lesions," which is a direct application to the patient's teeth, not an analysis of a biological sample.
Therefore, while it is a diagnostic aid, it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The LumiCare™ device is an oral rinse solution containing starch-based particles tagged with fluorescein. A specific volume is swished in the mouth, followed by a water rinse and air drying of teeth prior to exposure of the teeth to a blue light source with an irradiance of 450 mW/cm2 and wavelength of 450-470 nm. The clinician completes the clinical examination by observing fluorescence through light orange filter accessories, including protective eyewear, to aid the visualization of dental caries.

Dear Prithul Bom:
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.

V. INDICATIONS FOR USE / INTENDED USE
LumiCare™ Caries Detection Rinse is indicated to aid the dental professional in visualization of carious lesions.
The Indications for Use statement for the LumiCare™ device is identical to that of the predicate device, with minor exception. This difference does not alter the intended use of the device nor does it affect the safety and effectiveness of the device relative to the predicate.
Both the subject and predicate device have the same intended use of detection of dental caries.

Image /page/5/Picture/0 description: The image shows the logo for GreenMark Biomedical Inc. The word "GREENMARK" is written in a combination of green and black letters, with "GREEN" in green and "MARK" in black. To the right of the text is a green leaf design. Below the text, "BIOMEDICAL INC." is written in smaller, black letters.
| Characteristic | Subject Device | Predicate Device |
|---|---|---|
| Carrier for staining agent | Submicron Starch Particle | None |
| Viewing Conditions | Blue light/orange filter | Ambient light/white light with the naked eye or under magnification |
| Stimulation Wavelength | Blue light (450-470 nm, peak value) | Visible light |
The subject and the predicate device are both dye-containing liquids which bind to carious lesions on all (occlusal, facial, lingual, proximal) directly visible surfaces of the teeth, providing a visible indicator of the presence of caries. The subject and predicate devices have similar technological elements: liquid formulation, application directly to teeth and the liquid contains carriers, preservatives, and a staining agent.
Technological differences between the subject and predicate device include:
-
- Viewing Conditions: The predicate device's stain is visible under visible light whereas the subject device's stain is visible under blue light conditions when viewed through an orange filter. This difference does not impact safety or performance.
-
- Staining agent and carrier: The subject device contains submicron starch particles as a carrier for the staining agent, fluorescein, whereas the predicate contains blue dye with no carrier. This difference does not impact safety or effectiveness. The fluoresceinated starch particle was demonstrated to be non-cytotoxic, non-irritating and non-sensitizing.
VII. PERFORMANCE DATA
- A. Non-Clinical Performance Testing
Bench Testing
Sensitivity and Specificity testing was completed on extracted teeth using histologic reference standard for the LumiCare™ rinse and the predicate, demonstrating a high degree of reproducibility for the LumiCare™ rinse, and performance comparable to the predicate device. No FDA-recognized standards were available to inform the testing.
Simulated Use Testing
Simulated use testing in a clinical environment was performed by clinicians using a manikin model with extracted teeth placed in a typodont, demonstrating ease and effectiveness of use within the clinical workflow. No FDA-recognized standards were available to inform the testing.

Biocompatibility
A biocompatibility risk assessment was performed (per 2016 FDA Biocompatibility Guidance), along with cytotoxicity, sensitization, and irritation testing (per ISO 10993-5 and 10993-10), indicating the LumiCare™ rinse is biocompatible for use as intended.
Shelf Life Testing
Based on accelerated testing, a shelf life of two years is supported. Real time aging is being performed. No FDA-recognized standards were available to inform the testing.
- B. Clinical Performance Testing
Clinical performance testing was not conducted.
VIII. CONCLUSION
Based upon the indications for use and comparison of technology, together with the results from non-clinical performance testing, we find the LumiCare™ rinse used together with a blue light source, having an irradiance of 450 mW/cm2 and wavelength of 450-470 nm, is substantially equivalent to the predicate device Pulpdent Snoop™.
