hey guys a few questions thathave popped up during my revision that i hope u can help me out with.
1) in the margins of my page i had written GTR(guided tissue regeneration) and that it is best in class 2 defect(furcations) however im not really sure what it is,what this refers to and if it is relevent.. others opinoin or notes on this would be great
2)accessory canals in furcations. do accessory canals increase the chance of endo-perio lesions occuring. As Hirsch said i think last semester-endoperio can occur anywhere along the root surface so is this due to accesory canals??
3)I had in my notes also this. Cytokines in smoking are those associated with bone destruction(PGE-2) and not the ones associated with.......... ( i didn't get this last bit and i was hoping someone may have also copied down this sentence with the last part)
4) in perio modules Hirsch refers to 4a's for smoking, but we kow there are 5a's.I was just wondering for like this exam do we justassume there is only 4 as' thathe mentions and then in practice follow 5a principles?? i dunno just thought a question might pop up like( there are 4a's to help with smoking cessation) and i would be like ummmmm well... lol..
THANKS guys.
im sure i will have more eventually

1) I'm not really sure, cos I don't have it in my modules (shows how much I was listening in that lecture :S) but I have read about it GTR before. I think it's when a membrane is placed surgically over a defect, and the furcation defect filled with natural or artificial bone to try and get regeneration of the bone and some periodontal tissue. But I doubt this will be in the exam cos it isn't even in the module, he just mentioned it on the side didn't he?
2) I think accessory canals do increase the chance, as I have written down it is impossible to seal all canals. Therefore, if there is a pulpitis, and some furcation canals haven't been sealed, there may be localised bone loss in the furcation area?
3) I didn't have this in my notes, sorry!
4) I would say go along with the 4A's for Hirsch's exam, but remember that 5A's is the way to go!
Go with the 4A's for this exam.. 5 A's is the way to go though.
GTR.. Guided Tissue regeneration; means that the membrane is selective to the types of cells that migrate into the healing zone, in other words its a selectively permeable membrane (heard that before ??)that keeps epithelial cells out to allow Ct to reform.
Hope this helps!!
