Endodontic files and reamers, whether handheld or rotary-powered, are tiny instruments that have big impacts on performing root canal treatments. When you choose the best surgical instruments to clean and shape the root canal, successfully completing debridement of the canal and providing a shape that allows for optimal obturation, the clinician has confidence that the patient is getting the best root canal treatment and, therefore, the best chance to extend the life of the tooth. More general practitioners today are involved in endodontics thanks in large part to improved techniques and enhanced files. This month, we provide a look at some of the many products available to assist GPs and specialists in delivering root canal treatment. These files are designed to help clinicians combat pain, and they are changing the way people feel about the once-dreaded procedure.
