21st century endodontics. Part 4

The prime objective of this series of papers has been to focus the attention of the reader on the biological principles of root canal treatment. Accurate diagnosis, knowledge of the root canal morphology and the principles of modern preparation techniques are all essential so that appropriate chemical cleaning and disinfection of the entire root canal system may be accomplished. This paper will consider two further aspects of root canal treatment. First, whether the root canal system should be prepared and obturated in a single visit, and, if not, which intervisit medication is appropriate. Secondly, the modern concepts and techniques for obturation of the root canal system.
