Toothache and extreme cold sensitivity - Courtesy ROOTS
From: Rob Kaufmann To: ROOTS Sent: Tuesday, December 23, 2003 5:05 PM Subject: [roots] Whats up with this molar? Here’s a weird one I did this morning. 18 year old female with history of recent composite on lower left 2nd molar. No history of Ortho. Current complaint is toothache and extreme cold sensitivity. Referral says he had near exposure. (Translated: He’s exposed it no doubt.) Vital case, obviously. No periapical symptoms. Pre-op film looks very average. Looks like a slam dunk. I get into the tooth and the MB canal reads 14 mm with an apex locator while the ML is closer to 19 ! That MB file is a #25 as while I’m expecting some resistance as it goes around the mesial root S curvature there is none. Where’s it going? Something fishy is going on here. I take the WL film and I’m seriously LONG in the MB. It’s straight out the Mesial almost. I check the access again for possible MB perf NO way. I treat the ML and D and leave the MB to last. The foramen size ends up as a #55. ML and D done with ProTapers, hand S files and K reamers. MB, done with hand instruments only. Dried with paper points and got exactly the same WL. Custom cone fit the MB with chloroform dip and packed with Warm Vertical BU style. You can see the sealer track from the hole I poked in the PDL with the original WL file. It looks VERY much like a perforated case but it isn’t. Anyone else ever see one of these? - Robert M. Kaufmann DMD MS(Endo) |
