No
The device description focuses on the chemical composition and physical properties of a dental adhesive, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device explicitly states its use as a desensitizer/preventative in dentin hypersensitivity conditions by sealing exposed dentinal tubules to block fluid flow, which causes sensitivity. This function directly treats or prevents a medical condition.
No
The device is an adhesive and desensitizer used for bonding restorative materials and treating hypersensitivity, which are therapeutic and restorative functions, not diagnostic ones.
No
The device description clearly states it is a "light curing single component enamel/dentin adhesive" and a "light curing monomer mixture dissolved in ethanol," indicating it is a chemical 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 for bonding dental restorative materials to tooth structure and for desensitizing dentin. This is a direct treatment applied to the patient's tooth, not a test performed on a sample taken from the body to diagnose a condition.
- Device Description: The description details the chemical composition and mechanism of action for bonding and desensitizing within the mouth. It doesn't describe a test or assay performed on a biological sample.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health status.
The device is a dental material used for restorative and therapeutic purposes within the oral cavity.

Intended Use / Indications for Use
Gluma Comfort Bond + Desensitizer is a light curing single component enamel/dentin adhesive for bonding of all current brands of resin composite restorative materials and compomers. It also provides adhesion to metals such as amalgam. Gluma Comfort Bond + Desensitizer combines primer and adhesive in a single bottle.
Serves as a desensitizer/preventative in dentin hypersensitivity conditions by means of sealing exposed dentinal tubules which effectively blocks the fluid flow in the tubules that cause sensitivity.

Device Description
GLUMA COMFORT BOND + DESENSITIZER is a one bottle adhesive, designed to bond resinous restorative materials to dental hard tissue. It is an extension of the Gluma One Bond bonding system family. The product is a light curing monomer mixture dissolved in ethanol which, following conditioning with phosphoric acid, is applied to enamel and dentin prior to co- polymerization with the restorative. When compared with conventional bonding agents the main advantage of such simplified bond mediators is their reliability and ease of use in the dental office.
The composition of GLUMA COMFORT BOND + DESENSITIZER is based on three monomers which individually have been used in marketed dental products for decades. The hydrophilic hydroxyethylmethacrylate (HEMA) is essential for perfect wetting of and penetration into the conditioned tooth structure. Similarly, 4-MET(A) has hydrophilic and moieties for wetting and polymerization, whereas the urethane di-methacrylate monomer is responsible for formation of a cross-linked polymer network. The ethanol has the function of a carrier for the monomers while being an effective water chaser at the same time. The addition of glutaraldehyde to the Gluma One Bond formula allows the dental practitioner to obtain the complete desensitizing and other effects of Gluma Desensitizer and the bonding of Gluma One Bond all from one bottle. The combination of glutaraldehyde and HEMA in Gluma Desensitizer penetrates the dentinal tubules to a depth of 200um, setting up multiple walls that block the flow of fluids in the tubules. This immediately eliminates dentinal tubule-caused hypersensitivity. In addition, it has been found that glutaraldehyde bonds covalently to the collagen fibers, aiding re-wetting and resulting in reduced marginal contraction gap.
The application procedure is very easy. The solution is applied in small amounts to the conditioned moist tooth surface with two to three consecutive strokes, the water and ethanol is eliminated by a gentle air blast and finally, the resin is light cured for 20 seconds. Thorough in-vitro investigation has proven that the GLUMA COMFORT BOND + DESENSITIZER performs better than or at least as good as the leading resinous bonding systems available in the market. GLUMA COMFORT BOND + DESENSITIZER is also proven to bond to non-precious dental alloys, such as CoCr-based casting alloy and amalgam.
Based on this evidence and the cytotoxocity data, GLUMA COMFORT BOND + DESENSITIZER is recommended as an effective enamel/dentin adhesive when used in accordance with the instructions for use.
