Ambar is a lightcuring adhesive system for enamel and dentin, responsible for the bond between tooth structure and restorative materials. Classified as a two-step conventional adhesive, Ambar combines primer and adhesive into one bottle, requiring etching prior to the application of the adhesive.

Among the main features of Ambar, one can cite high immediate and post-cycling bond strength (on dentin and enamel), high chemical stability and resistance of the adhesive film generated after polymerization, adequate capacity of penetration of monomers into the collagen fibers of demineralized damp dentin, etc.
