The article discusses the benefits of using the Waterlase iPlus all-tissue dental laser from Biolase in root canal treatments. The author, an endodontist, shares their experience with traditional root canal treatment methods and how adopting the dental laser has improved their practice. They present two cases to illustrate the difference in treatment outcomes. The first case was treated without the dental laser, using traditional tools and techniques. The second case, treated with the dental laser, showed improved results, including better disinfection, reduced side-directed tenderness, and more conservative cleaning and filling of canals. The author emphasizes that the dental laser provides enhanced dentin debris removal, better management of complex canal configurations, and improved healing times. They conclude that investing in a dental laser has greatly improved their endodontic practice and expanded treatment capabilities.
