Access cavity preparations are important to attain longstanding success of endodontically treated teeth. However, this success determining step is sometimes neglected by clinging to the traditional designs which were formulated based on the armamentarium and restorative materials available at that time. It’s the time to shift towards more conservative preparation as nothing can compensate for natural dentin. This review vividly compares traditional approaches and various minimally invasive treatment methods in Endodontics. It focuses on strategies involved in attainment of long lasting of the treatment for successful results. All similar textbooks and articles were looked. Devan quoted once “Our goal should be perpetual preservation of what remains rather than meticulous restoration of what is missing” which could be attained by the shifting the focus from the concept of “extension for prevention” in endodontics to minimal invasion into the tooth structure. Minimally invasive approach requires in-depth knowledge of Root Canal Anatomy, Diagnosis and Decision Making, Preservation of Structural Integrity of Tooth, Alternate Access Designs, Image Guided Endodontic Access, Dynamically Guided Endodontic Access, Microguided Endodontic Access, Modern Bur Designs, Cleaning and Shaping, 3D Irrigation and Disinfection, Root Strengthening and Magnification aids like Loupes and Surgical Operative Microscope.
