This is an unashamed endo geek post- I completed this case today on what was a very tricky retreat, using MTA as the main apical filler for three of the four canal- all shortened with open apices and in the case of the palatal canal an apical third perforation.
At the time of writing the tooth is symptom free and has been built up in to the bite to allow some orthodontic work to be carried out (sadly the tooth is in a 20 year old and one of three badly damaged molars. The MTA offers a great solution to canals such as these allows for excellent healing. Both and the patient are aware that this is not a tooth for life but if we can keep in place through their 20s whilst the orthodontic and restorative work elsewhere can be completed then its replacement can be much more predictable.
