METHOD AND APPARATUS FOR OBTURATING THE CORONAL ASPECT OF A ROOT CANAL

摘要

There is provided a method of obturating the coronal canal of a tooth during root canal treatment. In the method described a cylindrical bore is formed in the coronal canal, into which an obturating element, having a generally cylindrical body, is located. The obturating element can include a self-sealing soft core through which a needle can be inserted to allow access to the apical canal. In one embodiment the obturating element expands resiliently to engage against the cylindrical bore in the canal and/or bonds thereto. A system for sealing the coronal canal of a root canal and a method for endodontically treating a tooth are also described.
