The Full Form of HEMA is 2-hydroxyethyl methacrylate.
2-Hydroxyethyl Methacrylate is a hydroxyester compound and a resin monomer used in desensitizing dentin. By applying 2-hydroxyethyl methacrylate locally to sensitive teeth, sensitive areas in the teeth get sealed and block the dentinal tubules at the dentin surface from stimuli that cause pain.
