Extrusion of endodontic materials revisited

 Got a chance to follow up on the incident in this previous post:   https://dental-tidbits.blogspot.com/2021/04/extrusion-of-endodontic-materials.html The clinic got a call from the patient that she was in a lot of pain about 9 days after the appointment. She had seen her doctor and was on antibiotics. She was double booked in into the clinic on the next day and I spent the day before the appointment stressing about what I had done and what I was going to do. I spent the night before researching about hypochlorite incidents and the management of. A lot of the serious complications of hypochlorite extrusion requires the dentist to bind the syringe needle and forcefully push the irrigant out the end. As I had some irrigant left in the calcified canal and the irrigant was forced out with the cavit placement, the actual volume of irrigant that could have been extruded is quite small and so the amount of damage and inflammation would be minimal.  In the end it turned out that ...

Resetting denture teeth

 Today I had the worst denture try in that I've ever had. The situation was the construction of a full over partial denture. The patient has a current full denture which he doesn't like the aesthetics of feeling the teeth aren't visible enough. He is a person who is a bit past a mid life crisis and spends his days chasing after women half his age. But to be fair, the incisal display was inadequate and unless he had a very wide smile, he looked edentulous and unsupported lip-wise. Naturally I took my jaw registration intending to increase the incisal display and ordered the A1 teeth to be set.  I don't know how it was so wrong but the midline was off by about 5mm and the incisal edge was down by about 5mm. I have never seen a sight more horrible. To my annoyance, the wax rims I had sent up were still sitting in the lab box meaning the technician had supposedly used them to mount the case and then set the teeth up without it. They can make an index over the lower cast to ...

Day 2 of Tom Giblin's Fixed prosthodontic course

 Just finished the second day of the course. It was another full day and as usual went after the allocated hours but Tom was fine to stay back and finish things off and answer questions. He went through more theory, a lot on diagnosis and occlusion and we prepped some more on the model and he finished off with some case studies.  Prepping on the model was a lot better as we found the sweet spot dialing down the handpiece power and developed a lighter touch of the bur. I found that prepping benchtop was very awkward and I found that I had to redevelop the way I hold the handpiece and utilise the finger rest.  The course itself felt more like a stitch together of multiple other courses i.e implant, treatment planning, occlusion courses rather than a stand alone course which makes sense as he had not run this course before and had most of the slides from an onlay course he had run a number of years ago. It felt as though a broad base of the basics were covered which were goo...
