A new case from Egypt Dr ahmed abo elkhier

it was just a routine endodontic treatment for first upper molar with acute pulpitis till my apex locator which i trust went mad in the mesiobuccal canal.
all canals length were on average but MB canal was about 16 mm which is very abnormal and goes against my preoperative radiograph.
well when things goes wrong a CBCT can save the day if it's possible,the patient was informed about the problem we have,a temporary root canal filling material were place till the length apex locator gave me.
on A CBCT view the mb canal had a periapical lesion that caused a pathologically resorbed wide open apex with leakage of large amount of fluid into the canal.
the canal was retreated till the full working length and after 3 visits we managed to get a dry canal,apical 3rd was closed using MTA & MTA Carier .6 (angelus).
then obturation material was set to the remaining canal space,case reported a post operative moderate pain that lasted for 24 hour,after 1 month follow up the case was a symptomatic and pain free.
the case was treated using the super flexible and amazing TC files from Videya.
