No
The device description and performance studies focus on the chemical and physical properties of a dental adhesive, with no mention of AI or ML.
No
This device is a dental adhesive used for bonding and sealing tooth structure, primarily for restorative purposes, rather than directly treating or curing a disease.
No
The device is a dental adhesive used for restorations, repairs, desensitizing, sealing, and priming of tooth structure. Its function is to form a hard sealant bonded to the tooth, not to diagnose a condition.
No
The device description clearly indicates it is a methacrylate-based dental adhesive, which is a physical material, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The intended use of this device is for direct application to tooth structure (dentin and enamel) for bonding and sealing purposes. It does not involve testing or analyzing samples taken from the body.
- The device description and intended use clearly describe a material applied directly to the tooth. It's a dental adhesive that polymerizes when exposed to light to bond to the tooth structure.
- The performance studies focus on material properties and bonding strength. These are typical tests for dental restorative materials, not for diagnostic devices.
Therefore, based on the provided information, the Nanova 2 Step Etch and Rinse Dental Adhesive is a dental material used for restorative and bonding procedures, not an in vitro diagnostic device.

Device Description
Nanova" 2 Step Etch and Rinse Dental Adhesive is a methacrylate based, visible-light activated, dental adhesive, the same as the predicate. This device is available in bottle or unit dose packaging, the same as the predicate. Nanova™ 2 Step Etch and Rinse Dental Adhesive contains ethanol, methacrylate resins, photoinitiator, and inorganic filler material the same as the predicate.
When irradiated by light, the methacrylate functionalities of the resins and surface-treated fillers undergo, in conjunction with the photoinitiator system, a light-induced polymerization to form a hard sealant that is bonded to the prepared tooth structure. Any differences between the subject device and the predicate do not introduce any introduce any new or increased concerns about safety or effectiveness.

Dear Andrew Ritts:
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. 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 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);

Biocompatibility:
Nanovation 2 Step Etch and Rinse Dental Adhesive completed a risk assessment covering the identification of legally marketed devices for all ingredients in the chemical composition and testing including: cytotoxicity (ISO 10993-5), irritation (ISO 10993-10), sensitization (ISO 10993-10), and acute systemic toxicity (ISO 10993-11).
Clinical Performance Testing:
Clinical performance data was not conducted.
Conclusion:
Nanova Biomaterials Inc. believes that Nanova" 2 Step Etch and Rinse Dental Adhesive is substantially equivalent to currently legally marketed products. Product based on comparison of similar intended use and technology together with the nonclinical performance testing. Any differences do not raise different questions of safety and effectiveness than the predicate, nor do they affect the safety or effectiveness of the subject device. These differences therefore do not render the new device NSE in comparison to the predicate.
