From practical negotiation tips to choosing a system that works in your hands, this episode focuses on the decisions that can make endodontics simpler, safer, and more predictable.\n https://www.youtube.com/watch?v=onZMR-872HQ \nWatch PDP271 on YouTube\nProtrusive Dental Pearl\nCut your gutta-percha at the level of the canal orifice and thoroughly clean the pulp chamber before placing the coronal restoration.\n⚠️ Leaving gutta-percha and sealer coronally can compromise the coronal seal and promote leakage.\n✅ Use isopropyl alcohol to clean resin-based sealer residue before bonding. Water is effective for cleaning bioceramic sealers.\nKey Takeaways\nEstablish a glide path before shaping whenever possible.\nD-Finders can negotiate difficult canals more predictably than traditional K-files.\nIntermediate files such as size 12 or 12.5 can help bridge the jump from size 10 to size 15.\nStraight-line access reduces file binding and improves shaping efficiency.\nAvoid forcing glide path files to working length.\nGates Glidden drills may be unnecessarily aggressive for routine coronal flaring.\nConsistency with one file system is often more important than chasing the latest product.\nWaveOne Gold remains a simple and user-friendly option for many GDPs.\nRotary and reciprocating systems can both achieve successful outcomes when used appropriately.\nA good glide path is often more important than the type of motion being used.\nHand files and Hedström files remain valuable during retreatment.\nMechanical GP...","thumbnail_url":"https://img.transistorcdn.com/hLSIeRiYSp0oTfIk0BzEukFutShD18hH3f6fq4QHsWw/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9lZmM0/ZTNjYzdiZDJhNGFj/MzBiYmU2NTUwNmM2/NzQ2My5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
