The device description and performance studies focus on the material properties and biocompatibility of a dental composite, with no mention of AI or ML.
No
The device is described as a composite material for aesthetic restoration of teeth, not for treating a disease or condition.
No.
The device is described as a composite material for "aesthetic restoration" of teeth, functioning as a "light-curved complex resin" that is "polymerized directly in the oral cavity" to mend "decay and damage." It is used for "recovering" and forming a "hard restoration." This indicates a therapeutic or restorative function, not a diagnostic one.
No
The device description clearly states it is a "composite material" and a "paste" that is polymerized in the oral cavity, indicating it 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 for "aesthetic restoration by getting polymerized directly in the oral cavity" for "Direct anterior and posterior restorations." This describes a material used in the body for structural repair, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details a "light-curved complex resin" that is applied as a paste and then hardened by light. This is consistent with a dental restorative material, not an IVD.
- Anatomical Site: The anatomical site is the "oral cavity; anterior and posterior parts (of teeth)." This is where the device is applied and functions, not where a sample is collected for testing.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information about a patient's health status.
In summary, the DiaFil & DiaFil Capsule is a dental restorative material used for filling cavities and repairing teeth, which is a medical device but not an in vitro diagnostic device.

Device Description
The product belongs to Group 1, Class 2 of Type 1 according to the standard classification of ISO 4049. It is a nano hybrid typed light-curved complex resin for aesthetic restoration for both anterior and posterior parts, which is used for restoration that requires aesthetics through decay and damage in a form of paste with unpolymerized dimethacrylate monomer, inorganic filler, and photoinitiators mixed. That is, after recovering with the unpolymerized product, to make a hard restoration by polymerizing through dental visible-ray polymerizer.

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
1
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).

8.2 Discussion :
The Change is only a package addition of DiaFil Capsule. The package includes 5" generation bonding agent (DiaPlus, K192392) and Etching agent (DiaEtch, K192273), which have already been proven to have Substantial product equivalence through the 510(k) decision of each product. The final package design of DIAFL START KT is added according to the configuration of package, but the products labeling of each components of package is not changed.
As the result of discussion of comparison, the package addition of DIAFIL CAPSULE does not affect to the original product.
9 Clinical Performance Data
No clinical data was collected or provided to support substantial equivalence between the subject and predicate devices.
10 Conclusions
Since the comparative products are components of the safely and effectiveness of subject product has already been proven in each aproved product. According to the conclusion, the subject device is practically the same as the predicale devices that are legally sold in market.
