|Pre-operative x-ray #19|
Root canal completed by another provider with separated file in ML canal. Tooth is extremely symptomatic.
|Post-operative x-ray #19|
Surgical approach was decided upon and no fractures noted. Three retro fills were placed, and a separated file was removed from ML canal with ultrasonics. Despite large size of lesion and the amount of bone loss, the prognosis was good.
Patient is asymptomatic and healing was noted.
Patient continues to be asymptomatic and the bone almost completely filled in
Comments: Separated instruments are just a way of life for those who do root canal therapy. The instrument itself is not a problem. What it represents is: a blockage of a possible dirty canal. In this case, I just speculated that the separated instrument was the cause of this patient's problem. Do I know this for sure? No. Therefore all canals were retrofilled.
