Stop taking OPGs/Panoral radiographs for TMD...they have limited benefit! In this episode I discuss the Piper Classification of TMJ with Dr Jim McKee from the Spear faculty. We also cover exactly when and why imaging of the TMJ may be beneficial (MRIs and CBCTs). I have found the Piper classification easy to implement and I hope this episode helps you understand it.\n\n\n\n\nhttps://youtu.be/n4lRWAQeA5A\nCheck out full episode on YouTube\n\n\n\nNeed to Read it?

If someone's jaw opens, and then it goes all the way to one side, and it doesn't go back to the middle, that's a DEFLECTION.\n\n\n\nIf you want to Download the PDF version of the Piper Classification of TMJ Infographic we made, click here!\n\n\n\nPiper Classification PDF\n\n\n\nDr Jim McKee is part of Spear Education - a platform that has taught me so much of my occlusion.\n\n\n\nIn this episode I asked Dr. Jim McKee:\n\n\n\nWhat is the Piper Classification of TMJ?What are the risks of having to rehabilitate someone where you haven't the health of the TMJ? (19:22)Are there any other useful TMD classifications? (21:01)Is there any benefit of taking a Panoral radiograph?

This is like a year and a half out of Dental school and I\u2019ll never forget this one patient I had, right? She came in and it\u2019s an emergency that had never seen before.\n\n\n\nJaz\u2019s Introduction:Like 99% was like acute pulpitis or an abscess. And you know we were doing extirpations and stuff. Now, this lady came in and she was literally like her mandible was all to one side. She was literally all deranged, she was in agony, she\u2019s pointing to a jaw joint, I forget which side she was pointing on now, but she was in absolute agony and just everything about her bite looked way OFF, right? and I had no idea or the diagnosis was. I didn\u2019t know. I had no idea what to do. So naturally what I did.The first thing I thought was okay. Looks like it could be something to do with the TMJ. I\u2019m thinking TMD. Therefore, what do we do? Why don\u2019t we get a radiograph? Okay? Because that\u2019s we do with teeth, right? We take a radiograph. So, I suggested again O.P.G. okay? So I sent this lady for an OPG. Okay? Anyway, the OPG/OPT comes back and you can\u2019t really notice anything unusual in it. And I show it to my consultant and my consultant absolutely flips to me. I mean it\u2019s like \u2018Jaz, what the hell you take an OPG for?\u201d Right? Because an OPG is not going to show you much when it comes to TMD. Alright?So that was the lesson number one I had several years ago, and I want to share that with you. And on that topic, I\u2019ve had brought on, someone absolutely amazing today is from the spear faculty.
