Subject: [roots] 3 canal max bi, cracked

Patient complains of  of Pain to biting. Referring Dentist wasnt sure, 
and quite rightly made an immediate referral. O/E 13 was found cracked. 
Mesio distal crack from the occlusal extending  into the chamber but not 
down the root. RCT completed with a very conservative access to preserve
dentin. patient is recommended a cuspal  /Full coverage to prevent the 
crack from getting worse.

its incredible how many patients i treat have three canals in the 
maxillar/mandibular bicupids. As in this patient, you see fairly regularly 
in patients , all premolars (both upper /lower arches) with three canals.
Jamaican population is full of these teeth - Sashi Nallapati

Hi Sashi, Beautiful work.What was your instrumentation sequence - Imran access, use hand files to 20 to open the orifices, TF 10, 08 ,06 and 04 files till i can get the 06/25 to length. hand files in between each rotary to maintain patency. sequence 04/30 in the buccals to finish and 04/35 in the palatal - Sashi
