I believe I see what you are seeing, but I’m attributing it to normal radiographic changes in a tooth undergoing orthodontic traction. I think I’d be of the mindset to monitor it some more - gary Marga, did the patient have orthodontic treatment in the meantime? - Jörg It will be interesting to see if there is any distraction of the apical fragment during the orthodontic treatment - Stephen. Dear Marga, mesial and coronally of the fracture line it seems to me if there is some area of external resorption - Bart I do see this area as well---a rather large, ovoid area? if we are talking about the same area, i'm not sure what to make of it either, sorry no help, - Kendel Marga it does look like a radiolucent area apically and coronally to the fracture line.............................. One question regd. packing the canal space with composite ..................What bond do u prefer........ I mean which generation and what type of composite do you use? Is packable posterior composite a choice and are you depth curing the composite ? - Sachin Sachin, A packable composite is way too stiff to apply in a canal space. I prefer a self cure build-up material with the right consistency to put it in a needle tube and squirt it in the canal space, for me LuxaCore does the job. LuxaCore is also available in a dual cure version. The reason for me to choose a self-cure, is because their relatively slow-setting rate are thought to provide flow to relieve the shrinkage stress developed during setting. For bonding material, see attached pics - Marga

I use gold Build It for this, Marga. It leaves a soft back ground for all porcelain crowns and is easily identifiable as not being tooth. Guy Marga: Do you have any concerns that by placing a composite post/core buildup of that magnitude that you may be committing the patient to surgery in case of retreatment as access may be difficult? - Gary Gary, In this case I placed a fiber post in the bulk of composite. I do this amongst others to facilitate retreatment if necessary. You can remove a fiber post quite easily, provided you have a scope and can see what you are doing. Another advantage is that by placing the post, you're reducing the mass of composite and therefore reducing the polymerization shrinkage. It also gives the build-up more stiffness. These are some of the reasons that I usually insert passively a fiber post after making a build-up of composite of that magnitude - Marga Somehow I couldn’t see you cramming composite 2/3 the length of a root, but somehow I missed the fiber post part. Sorry about that - Gary
