Device Description
Senzzzzz Away is an oxalate tooth desensitizing agent intended for over-the-counter-use. The combination of tubule occlusion and reduction in nerve excitability shown with oxalate formulations is responsible for the reduction in dentinal hypersensitivity to cold, hot and sweets. Senzzzzz Away is a one-part, opaque gel for single use.
More Information

Not Found

No
The device description and performance studies focus on the chemical and physical properties of the gel and its effect on dentinal tubules, with no mention of AI or ML.

Yes
The device is described as an oxalate tooth desensitizing agent intended to relieve dental hypersensitivity and is shown to be effective in reducing sensitivity.

No

Explanation: The device is described as an "oxalate tooth desensitizing agent" intended "To relieve dental hypersensitivity." Its function is to reduce sensitivity, which is a treatment or therapeutic action, not a diagnostic one. While it "reduces dental hypersensitivity to cold, hot and sweets," this is the effect of the treatment, not a diagnostic output.

No

The device description clearly states it is a "one-part, opaque gel," 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 "To relieve dental hypersensitivity." This is a therapeutic or palliative purpose, not a diagnostic one.
  • Device Description: The description details a topical gel that works by occluding dentinal tubules and reducing nerve excitability. This mechanism of action is directly applied to the patient's teeth, not used to test a sample taken from the patient.
  • Lack of Diagnostic Elements: There is no mention of analyzing samples (like blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis.

IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Side-by-side biocompatibility testing was performed on the subject and predicate devices. Scanning electron microscopy images of extracted teeth before and after device application demonstrated that the device seals and occludes dentinal tubules.

A consumer ease-of-use study conducted for Senzzzzz Away to ensure that patient use of the product was appropriate for over-the-counter purchase. A six month effectiveness study was performed to demonstrate the reduction in sensitivity. The combination of these studies shows Senzzzzz Away is safe and effective for over-the-counter use.
