Subject: [roots] Anomalous Missed DL canal
Hereís the case I posted where I took a CBCT to show the missed DL canal is a separate DL root on this
failing lower molar.
I finished the treatment this morning - Terry
would an angled preop xray have demo'd this root?
(as per the joey d recommendation of taking three xrays as a preop SOP) - Craig Barrington
I was suspicious of it on the different angles I took. I actually take about 5 -6 preops for each case.
Here are two very different angles, you can see the DL root clearly. I knew it was there I just needed
the CBCT to feel confident triangulating the distance internally using the DB orifice as a reference point
so I could pin point the DL orifice location unequivocally - Terry
Wow, thanks for sharing - Ronald
Dr.Pannkuk, Thank you for showing this great retreatment case. It is amazing to see more complex root anatomy
after DB was retreated.
I noticed that you retreated the mesial roots as well. Although I would do the same when I see my pts,
a question is always there. If I sealed the mesials well with GP and Flowable resin, should I touch them?
I would definitely retreat them if I saw clear sign of apical lesion after 1 year. - Hongsheng
I donít trust other clinicianís work and canít remember ever just retreating one root in a case. - Terry
