Subject: [roots] Super-long curved, complex roots with difficult access-CBCT

This patient was very difficult to treat; just finished him a few minutes ago.  
The CBCT was helpful just so I could validate what I did at the end and make 
sure I didnít miss any major systems (I didnítí charge because it was mainly
for my personal interest). There wasnít really a separate MB2 orifice but I 
felt some action apically as I went through numerous recapitulations with 
precurved K-files.    Same with the palatal.  My EAL estimate was 2mm short
(as usual I trusted the RT more.good thing).  The MB had an apical trifurcation 
which can be seen on the transverse sections.  It also had a prominent furcation 
accessory at midroot. Wild case, good demo CT, almost cone-cut the
palatal root on the CT.  The patient was very tall -  Terry

Hmmm, the thickening of the sinus membrane adjacent to the palatal root looks suspiciously familiar. Was this a necrotic tooth? Please make a note to CBCT this tooth again in 6 months to assess the change (or not) of the sinus post-RCT. - michael p was necrotic and this was the second visit. The palatal root was 28 mm long, DB 26mm and the MB short branch 23.5mm and the MB long branch 25.5mm. The CBCT simply showed what I did and did not help me do it; hence the free charge. There was no COD with the CBCT for this case - Terry
