More Information

None

No
The 510(k) summary describes a fluoride varnish, a chemical substance applied to teeth. There is no mention of software, algorithms, or any technology that would typically incorporate AI/ML. The description focuses on the chemical composition and intended use for treating dental hypersensitivity.

Yes
The device is used for the professional treatment of dental hypersensitivity, which is a therapeutic purpose.

No

The device is a fluoride varnish used for the treatment of dental hypersensitivity and to promote remineralization, not for identifying or diagnosing a condition.

No

The device description clearly indicates it is a physical substance (resin-based varnish) applied to teeth, not a software program.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVDs are used to examine specimens derived from the human body. The intended use of Pulpdent Fluoride Varnish is to be applied directly to enamel or dentin in the mouth for the treatment of dental hypersensitivity. It does not involve the analysis of a specimen taken from the body.
  • The description focuses on a topical application for treatment. The mechanism of action described (occluding dentinal tubules, promoting remineralization) is a direct therapeutic effect on the tooth structure, not a diagnostic test performed on a sample.

Therefore, Pulpdent Fluoride Varnish falls under the category of a dental therapeutic device, not an in vitro diagnostic device.
