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.

Protrusive Dental Pearl: Observe the patient's path of opening. If someone's jaw opening makes a 'V' shape, that's a DEVIATION. 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.

Opening Snippet: I used to work in the emergency department of a very large dental hospital. This is like a year and a half out of Dental school and I’ll never forget this one patient I had, right? She came in and it’s an emergency that had never seen before.
Jaz’s 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’s 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’t 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’m thinking TMD. Therefore, what do we do? Why don’t we get a radiograph? Okay? Because that’s 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’t really notice anything unusual in it. And I show it to my consultant and my consultant absolutely flips to me. I mean it’s like ‘Jaz, what the hell you take an OPG for?” 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’ve had brought on, someone absolutely amazing today is from the spear faculty.
