The device description and performance studies focus on the material properties and biocompatibility of a light-cured resin, with no mention of AI or ML capabilities.
Yes
The device is described as a "light-curved complex resin for aesthetic restoration for both anterior and posterior parts" used for "restoration that requires aesthetics through decay and damage," which directly addresses and treats a medical condition (dental decay/damage).
No
The device is described as a light-curved complex resin for aesthetic restoration, indicating it is used for treatment and repair rather than diagnosis.
No
The device description clearly states it is a "light-curved complex resin" in a "paste form" and is packaged with physical components like a syringe and disposable tip. This indicates it is a physical material, not software.
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. They are used to provide information for diagnosis, monitoring, or screening.
- Device Description and Intended Use: The description clearly states the device is a "light-curved complex resin for aesthetic restoration" used for "restoration that requires aesthetics through decay and damage." Its intended uses are for restoring dental cavities (Class III, V, smaller IV), repairing dental materials, and undercut blockout.
- Lack of Biological Sample Testing: There is no mention of the device being used to test or analyze any biological samples from a patient. It is a material applied directly to the tooth.
- Performance Studies: The performance studies listed focus on material properties, biocompatibility, and safety standards related to dental restorative materials, not diagnostic accuracy or performance on biological samples.
Therefore, this device falls under the category of a dental restorative material, not an in vitro diagnostic device.

Dear Kab Lee:
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.
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
1
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.

| Description | DiaFil Flow belongs to Group 1 of Class 2 of Type 1 according to the standard classification of ISO 4049. It is a light-curved complex resin for aesthetic restoration for both anterior and posterior parts. It is used for aesthetic restoration which is caused by decay and damage, and it is a paste form consisting of a mixture of unpolymerized dimethacrylate monomer, inorganic filler, and photoinitiators. That means that it makes a hard restoration by polymerizing through dental visible-ray polymerizer after recovering with the unpolymerized product. | DenFil Flow is a light-cured radio-opaque flowable restorative resin. It is composed of Epoxyacrylate (Bis-GMA), Diurethane dimethacrylate, Triethylenglycol dimethacrylate, Barium aluminosilicate, and other materials. As Denfil flow has a lower viscosity than paste type composite resin-Flow; 0.16 mm/30sec, so it can restore narrow & deep cavity easily. DenFil Flow can be applied to fill cavities of all types exactly and efficiently by using a disposable tip. And DenFil Flow has various shades that correspond to the most common used shading system. | Equivalent |

The main compositions are similar, but the compositions of DiaFil Flow and the predicate device are not same completely. However, DiaFil Flow and the predicate device are substantially equivalent through Biological Safety Assessment Report. (#BSA-2018-14)
The subject device has the similar technological characteristics as the predicate device: indications for use, main raw materials, mechanical properties (curing time, photopolymerization type resin).
ConClusions
Based on the above information and all data provided in this submission, the comparison of indications for use, technological characteristics, and non-clinical performance testing demonstrates that the subject device is substantially equivalent to the legally marketed devices identified in this submission.
