autoetch

Autoetch refers to a process used in dentistry involving the self-etching of tooth structure. It combines the etching and priming steps into a single application. This technique aims to simplify the bonding procedure for dental restorations. Typically, a self-etching primer or adhesive is applied directly to the tooth surface, which contains acidic monomers. These monomers simultaneously demineralize the enamel and dentin and infiltrate the created micro-pores. This creates a hybrid layer that facilitates adhesion between the tooth structure and the restorative material. Autoetching materials are often used in conjunction with composite resins for fillings, sealants, and other adhesive dental procedures. The advantage of this method is its reduced technique sensitivity compared to traditional total-etch systems, which require separate etching and rinsing steps. It can also minimize the risk of over-etching or post-operative sensitivity. Various formulations of autoetching adhesives exist, differing in their acidity and bonding characteristics, and their selection depends on the specific clinical application and desired performance.
