The smear layer consists of an organic portion (coagulated proteins, necrotic and non-necrotic pulpal tissue, odontoblastic processes, saliva, blood cells, and microorganisms) and an inorganic portion (minerals from the dentinal structure).5 Elimination of the smear layer from the root canal system results in cleaner and unconcealed dentinal tubules, promoting a better apical sealing with the filling material by allowing easier infiltration of the dentinal tubules.5
