The device description and performance studies focus on the material properties and physical characteristics of a dental veneering paste, with no mention of AI or ML technologies.
No
The device is a dental veneering material used to enhance the aesthetic appearance of dental prostheses (artificial teeth), not to treat or cure a disease or condition.
No
The device is described as a "dental veneering material" used for color staining and glazing of dental restorations, and its purpose is to make "artificial teeth (dental prosthesis) more similar with natural teeth." It does not detect, diagnose, treat, or prevent any medical condition.
No
The device is a dental veneering material in paste form, which is a physical substance, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is clearly stated as a "veneering material for fixed prosthesis in crowns and bridges" and "forming a porcelain veneer on to a ceramic substructure." This describes a material used in the mouth for dental restoration, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description reinforces its use as a "dental veneering material in paste form used for color staining and glazing of the surfaces of restorations." This is a material used in the fabrication of dental prosthetics.
- Lack of Diagnostic Purpose: There is no mention of the device being used to analyze a sample (blood, urine, tissue, etc.) or to provide information for the diagnosis, monitoring, or treatment of a disease or condition.
- Performance Studies: The performance studies focus on material properties (Appearance, Weight, Uniformity, Chemical solubility, Flexural strength, etc.), which are relevant to the physical and chemical characteristics of a dental material, not the analytical performance of a diagnostic test.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic purposes. This device is used in vivo (in the mouth) as a restorative material.

Device Description
rainbowTM Paste Stain SE is a dental veneering material in paste form used for color staining and glazing of the surfaces of restorations such as porcelain-fused zirconia, full-contoured zirconia, or lithium disilicate.
The intended use of general porcelain is to make artificial teeth (dental prosthesis) more similar with natural teeth. The subject device is pre-mixed paste form, which can help dental technicians exclude mixing process of porcelain powder and liquid.

§ 872.6660 Porcelain powder for clinical use.
(a)
Identification. Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish.(b)
Classification. Class II.

Dear Hayoung Sung:
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 (the 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 available 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.
