Gluma
From Wikipedia, the free encyclopedia
Gluma is a brand-name desensitizer, used in dentistry to treat sensitivity, product created by manufacturer Heraeus Kulzer, a German company.
Its formula of 5% glutaraldehyde and 35% HEMA (hydroxy-ethyl methacrylate) in water[1] is used to help control both hypersensitive dentin and reduce the incidence of post-operative sensitivity in restorative dentistry procedures. It’s also useful as a cavity disinfectant, a rewetting agent and an adhesion promoter (when combined with most dentin bonding systems).
Research indicates that when used as a desensitizer under bonded restorative material, Gluma has no significant influence on bond strength, unlike some other liners, which contribute to a decrease in bond strength.[2] In one study, potassium nitrate was more effective at reducing sensitivity.[3]
