This article reported an upper right lateral incisor with type III dens invaginatus using the method that removed the invagination under the dental operation microscope, and then mineral trioxide aggregate apical barrier was made for the convenience of next treatment. The 26-mo follow-up revealed a satisfactory therapeutic effect.
