A tough retreatment with a huge radiolucency. Patient was young and motivated to try to hold on to her tooth, if possible. I was motivated to try given the poor quality of the original obturation. (Patient was made aware pre-op that the crown would need to be replaced due to open margins.)
The first visit brought the added challenge of discovering and removing plastic Thermafil carriers from the mesial canals. The distal root presented with two canals, but I was only able to achieve patency in the Disto-Lingual. CBCT imaging suggested that the distal canals merged apically, but I could not get an instrument through the DB.
At the second visit, the EdgePro YSGG laser system was used for activated irrigation of the root canal system. The final obturation demonstrated retrograde sealer fill of the previously blocked DIsto-Buccal canal. Additionally, a lateral canal was popped on the distal root. The patient has been scheduled for six-month recall.
We had the EdgePro system installed in the office one week ago. Since then, I have been very happy to have the EdgePro system on hand for cases like this!
