The 510(k) summary describes a dental material (resin-modified glass ionomer) and its physical properties and performance in bench testing. There is no mention of AI or ML technology in the intended use, device description, or performance studies.
No
The device is used as a liner, base, or luting material in dental restorations, which are structural and restorative functions rather than therapeutic. While it mentions the release of "beneficial ions," its primary role is not to treat or cure a disease or condition.
No
The device is described as a material (liner, base, or luting material) used in dental restorations, which is a therapeutic rather than diagnostic function.
No
The device description clearly states it is a "resin-modified glass ionomer preparation," which is a physical material used in dental restorations, 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 as a dental material (liner, base, luting material) used in the mouth for dental restorations. This is a therapeutic or restorative use, not a diagnostic one.
- Device Description: The description details the chemical composition and setting mechanisms of a dental material. It does not describe a device used to examine specimens from the human body to provide information for diagnosis, monitoring, or compatibility testing.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information.
- Performance Studies: The performance studies focus on the physical and mechanical properties of the material (strength, setting time, radiopacity), which are relevant to its function as a dental restorative material, not a diagnostic device.
In vitro diagnostics are devices used to perform tests on specimens taken from the human body outside of the body (in vitro) to provide information for medical purposes. This device is used directly in the patient's mouth for a restorative purpose.

Device Description
Pulpdent RMGI Low Viscosity is a resin-modified glass ionomer preparation with both a bioactive resin matrix and bioactive glass fillers. In this context, 'bioactive' refers to the release of beneficial ions from the resin and glass fillers into the oral environment. As a resin-modified glass ionomer, RMGI Low Viscosity has three setting mechanisms: light cure, self-cure resin chemistry, and acid-base glass ionomer reaction. It contains no Bisphenol A, no Bis-GMA and no BPA derivatives. RMGI Low Viscosity is a paste-paste formulation provided in an automix syringe.
