21st century endodontics. Part 1.

Root canal treatment techniques probably develop and change more frequently than any other area of dental practice and it can be hard for the busy general dental practitioner to keep up to date. The aim of this series of five papers is to give a thorough review of current teaching and practice. This will encompass the rationale of root canal treatment, guidance on the latest technical procedures for preparation and obturation of the entire root canal system, and consideration of how these principles may contribute to successful treatment. The series will address the following issues: diagnosis and treatment planning; root canal morphology and access; control of infection by effective isolation and anti-microbial agents; the philosophy of modern canal preparation techniques; single- or multi-visit treatment with relevant canal medication; obturation; diagnosis of failure and considerations in re-treatment. It is hoped that readers will be encouraged by the series to question their own techniques, audit their outcomes, and adopt new techniques only after careful reflection of the underlying principles involved.
