Dear Dr. Tricia Cregger:

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.

{1}------------------------------------------------

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.

| The proposed Coltolux Comfort LED Curing Light (Coltolux Comfort) is used for the polymerization of light-cured resin materials used in<br>dental restorations. The Coltolux Comfort incorporates a focused high-power LED to produce light in the "deep blue" spectrum<br>(wavelength 440 - 470 nm) for activating Camphorquinone (CQ) photo-initiators. The device is utilized by placement of the lens within<br>close proximity to the surface of the material to be cured, activation of the curing light via the pushbutton switch, and retention of the<br>tip near the dental material until the composite is cured. | | | | |
| Intended Use/Indications for Use | | | | 21 CFR 807.92(a)(5) |
| The Coltolux Comfort LED Curing Light is indicated for the polymerization of intra- and extraoral dental rom<br>materials (commonly referred to as visible light cured dental restoratives and/or dental adhesives) that contain<br>Camphorquinone as the photoinitiator. | | | | |
| Indications for Use Comparison | | | | 21 CFR 807.92(a)(5) |
| The indications for use of the Coltolux Comfort LED Curing Light are the indications for use of the predicate device, the<br>Coltolux LED Curing Light (K040551). | | | | |
| Technological Comparison | | | | 21 CFR 807.92(a)(6 |

The Coltolux Comfort LED Curing Light (subject device) and the Coltolux LED Curing Light (predicate device) are both LED curing lights for dental composite material. The indications for use and technological characteristics are substantially equivalent with only minor
