GLUMA Desensitizer is indicated for the treatment of hypersensitive dentine. They eliminate pain in exposed cervical areas which do not require restoration, and alleviate or prevent dentinal sensitivity after preparing the teeth to receive direct or indirect restorations.
GLUMA Desensitizer is suitable prior to the placement of direct and indirect restorations. The desensitizer function solely within the dentinal tubuli. Thus, they do not interfere with dental adhesives nor adhesive resin-based luting materials.
In combination with adhesives used in total etch or selective enamel etching technique, GLUMA Desensitizer should be applied after phosphoric acid etching.
In case of self-etch adhesives, GLUMA Desensitizer is to be applied prior to the adhesive.
GLUMA Desensitizer should be left on the dentine for 30-60s. Afterwards, it needs to be rinsed off with plenty of water.
Various studies have confirmed that GLUMA Desensitizer is fully compatible with dental adhesives and luting cements. The bond strength of these materials to the tooth remains on the same level irrespective of whether GLUMA Desensitizer is previously applied on the dentine or not. Some other desensitizing products act only at the tooth surface. This may decrease bond strength to adhesives or cements applied afterwards.1 GLUMA Desensitizer does not interfere with these adhesive materials because they work within the dentinal tubuli.

GLUMA Desensitizer contains glutardialdehyde. This substance is responsible for the effective reduction of dentine hypersensitivity. It is a highly reactive agent able to coagulate proteins. This effect is desired within the dentine tubuli but not on the gingiva and mucosa. We therefore strongly recommend the use of rubber dam. To avoid irritation of oral soft tissues, GLUMA Desensitizer must never touch soft tissue and must be rinsed off with plenty of water by the dentist/dental assistant.
After application on the hypersensitive tooth area, GLUMA Desensitizer needs to be air-dried. This step increases the desensitizing effect. Afterwards, the desensitizer needs to be rinsed off using plenty of water by the dentist/dental assistant.
GLUMA Desensitizer contains glutardialdehyde. This agent is very effective in the coagulation of proteins, providing the desired result within the dentine tubuli. However, it also reacts with oral soft tissue when it comes in contact with gingiva or mucosa. This may cause temporary local irritations or necrosis of the soft tissue. To avoid any contact with oral soft tissue, rubber dam needs to be applied.
Light-curing does not affect GLUMA Desensitizer. The desensitizer does not contain photocuring ingredients.
GLUMA Desensitizer is one of the most evaluated desensitizers worldwide: at least 34 clinical patient studies were done on the performance of GLUMA Desensitizer and numerous in-vitro investigations. (You will find a list of these studies at the end of this document.)
Several clinical studies demonstrated a minimisation of the dentine hypersensitivity directly after its application2. Its full effect will occur after some minutes to hours once the reaction of GLUMA Desensitizer with the proteins of the dentine liquor is completed. In some cases, a repeated application of GLUMA Desensitizer may be necessary.

GLUMA Desensitizer contains glutardialdehyde and HEMA ((2-Hydroxyethyl)methacrylate). HEMA enables glutardialdehyde to penetrate up to 200μm into the dentine tubuli3. Inside the tubuli, glutardialdehyde reacts with the proteins present in the dentine liquor. The proteins precipitate and form protein plugs which close the dentine tubuli. This protein coagulation leads to the polymerisation of HEMA4. Because of these coagulated proteins (protein septa), the permeability of the dentine is significantly reduced5 and movements of dentine liquor inside the tubuli or other stimulating effects are lessened. GLUMA Desensitizer functions within the dentine tubuli and therefore do not interfere with adhesive treatments. It does not create a layer on the dentine surface. Other studies have shown further benefits from glutardialdehyde. It inhibits enzymes (MMPs) within the dentine that degrade the hybrid layer of adhesives over time6. Apart from this, glutardialdehyde has also demonstrated its potential for cavity disinfection7. Last but not least, it increases the strength of the dentine and may lead to more durable bonding8.

A recently published clinical study revealed a reduction of dentine hypersensitivity by GLUMA Desensitizer for at least 18 months9. GLUMA Desensitizer was the only tested desensitizing treatment that did not show an increase in pain during the 18 months study observation period.

GLUMA Desensitizer has demonstrated their long-term effectiveness of up to 18 months in various clinical studies10. GLUMA Desensitizer is fast and non-invasive. It should only be applied by dentists, though, as it is not intended for use by the patients. It does not interfere with other treatments (e. g. following adhesive treatments) compared to other desensitizing treatments (e.g. desensitizers based on oxalates11, 12). GLUMA Desensitizer is more effective than desensitizers based on an oxalate or calcium phosphate chemistry13, 14, 15.

GLUMA Desensitizer has been launched in 1992. GLUMA We estimate that GLUMA Desensitizer has been applied on teeth about 45 million times and that 34 studies have been carried out on GLUMA Desensitizer. (You will find a list of these studies at the end of this document.)
GLUMA Desensitizer has a pH value of 3-4.
