Mounted Mandibular molar. I think, and I could be wrong here, that this is the last hand instrumented tooth we do. Starting with our next project we will be doing rotary endo. Good timing too because our contra-angle endo handpieces just got in!

| Endo and my camera are not good friends. I either forget it a crucial peice of my camera (battery, or the whole thing), or am in such a hurry to keep my head above water with all these projects, that I am 1/2 done with a project before I realize I have forgotten to take pictures... Bear with me folks |

| This is the last non-angled radiograph I took. We take angled radiographs so we can see the two different canals. How do we know which canal is which? A: Well, the SLOB rule of course... |

| Master Files to length fitting around those curves. Even though we are at our master files, we still need to taper the canals to fit Gutta Percha and clean out the larger aspects at the occlusal 1/3 of the root. To do this, we are going to use the Step Back Technique (which we have used for every project as well) |

| Since we have a total of 7 digital xray machines down in the preclinical sim lab & bench lab, I thought, "hey, Why not just take a picture of all my cones in there to make sure I didnt push one down past the apex." Actually, this is my logic for taking ~500 radiographs for each step. A little exaggeration but me thinks it is common that most students take more radiographs than necessary/ would ever take on a real patient because it is there and we can check our progress. |

| Final Obturation. The ML canal is not perforated nor does it have GP sticking out the end. That is just excess sealer that either got extruded during lateral condensation, or was pushed out by my root plugger. Either way, it wont be counted down. I forsee myself losing points for being closer than 0.5 mm from the radiographic apex. But besides for that, I think it looks very good :D |

That's a great job!! I had some problems to understand endodoncy this year but at the end I understood. I have to admit that your scheme is very useful, I wish I had it before my exam. Continue like this! Good luck with next.

Thanks Lydia! I agree, there is such a "A HA!" moment when you finally make that tactile-mental connection and are able to visualize where your file is in the root compared to the anatomy/radiograph! Endo is a lot of fun, but can be tedious. I cannot imagine doing this all day, every day - but I would not mind having the skills to make this a good practice builder.
ReplyDeleteI'm agree with u, I cant be all day doing this. I wanna do an specialization one day but I'm pretty sure that is not gonna be endodoncy. I prefer surgery or implants, or something more quickly. What do u think?
ReplyDeleteThis is interesting, we didn't use these plastic teeth :/ we practiced on extracted teeth in our preclinical lab for endo before we started with patients.
