Proper seal at the coronal, middle and the apical end of a root canal is achieved only if the material has the ability to seal the root canal dentin in all directions. A new self-sealing root canal obturation system called as C-points (EndoTechnologies, LLC, Shrewsbury, MA) based on polymer technology has been introduced which undergoes lateral hygroscopic expansion when in contact with moisture in the root canal. The aim of this review is to provide a basic overview of its composition and properties after analysing few related studies.
