• Applicant: DiaDent Group International
• Product Code: KLE · Dental
• Decision Date: Jun 15, 2022
• Decision: SESE
• Submission Type: Special
• Regulation: 21 CFR 872.3200
• Device Class: Class 2

Intended Use

- All direct restorations - All indirect restorations - Desensitizing/sealing of tooth - Intra-oral repairs

Device Story

Dia-X Bond Universal is a single-bottle, light-cured resin tooth bonding agent used by dental professionals in clinical settings. It functions as a universal adhesive capable of total, self, and selective etching. The device contains 10-methacryloyloxydecyl dihydrogen phosphate (MDP), which utilizes a hydrophobic carbon chain and hydrophilic phosphate group to permeate dentin and enamel, increasing bonding to hydroxyapatite. After application to the tooth surface, the solvent is volatilized and the material is photopolymerized. The output is a bonded interface between the tooth structure and the restorative material, facilitating direct and indirect restorations, tooth desensitization, and intra-oral repairs. The device is intended for prescription use only.

Clinical Evidence

No clinical data was collected or provided. Substantial equivalence is supported by bench testing, including film thickness, shear bond strength, sensitivity to ambient light, and occlusion of dentinal tubules, alongside biocompatibility testing per ISO 10993 series (genotoxicity, sensitization, irritation, systemic toxicity). Cytotoxicity testing was deemed not applicable due to the acidic nature of the 10-MDP monomer.

Technological Characteristics

Universal resin bonding agent; single-bottle system. Composition includes 10-MDP, HEMA, BisGMA/TEGDMA, and silicon dioxide. Principle: photopolymerization after solvent volatilization. Conforms to ISO 4049 (polymer-based restorative materials) and ISO 29022 (notched-edge shear bond strength). Biocompatibility evaluated per ISO 10993-1, 3, 5, 10, and 11. No software or electronic components.

Indications for Use

Indicated for all direct and indirect dental restorations, desensitizing or sealing of teeth, and intra-oral repairs in patients requiring dental adhesive procedures.

Regulatory Classification

Identification

A resin tooth bonding agent is a device material, such as methylmethacrylate, intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restoration, such as a filling.

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

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

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 (OS) 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).

#### Diadent Group International

(Among the components of this product, 10-MDP is an acidic monomer, and depending on the acidity, it is a substance that causes cytotoxicity according to the principle of action of this product, so cytotoxicity test setting the test item is meaningless.

#### 9 Clinical Performance Data

No clinical data was collected or provided to support substantial equivalence between the subject and predicate devices.

#### 10. Conclusion

Based on the above information and all data provided in this submission, the comparison of intended uses, technological characteristics, and non-clinical performance testing demonstrates that the subject device is substantially equivalent to the legally marketed devices identified in this submission.
