Guest guest Posted March 27, 2010 Report Share Posted March 27, 2010 Hi viktoriia, first a small advice if u don't mind, I am Still having the same problem tho, but I found that these questions don't need too much knowledge unfortunately because if u know a lot this is when u r going to miss the correct answer, so my advice is let ur answers follow the KISS principal (keep it simple stupid), let's get back to the question and I will tell u how I reason: A 45 years old (woman?man?) if it was a she straight away u might be able to think of rheumatoid arthritis (age 20-40) if she was 60 then osteoarthritis but read the question u don't have any info about pain trismus reduced mouth opening deviation of the mandible and so on so y make it complex? Now a word about clicking : 3 types of clicking on opening, on closing or reciprocal (both together ) Y does it click? The posterior distal ligament of the disc will become loose and the disk will be freed to move anteriorly mainly due to the superior belly of the lateral pterygoid so on opening the condyle will squeeze the disc and once pass it the disc will jump back causing the audible click noise The click on closing similar but this time the condyle will jump to his right place causing the disc to move anteriorly or medially and u have the click in all these cases u have a displacement with reduction If the disc is trapped whether on closure or on opening then u will have a locked jaw respectively and this is a displacement without reduction Now this patient when he/she moved her jaw anteriorly she/he pushed the disc back to the right place and hey ho the click disappeared.Is that helpful? Another thing I saw something about a question u answered regarding the source of free energy and u answered ATP, again KISS its glucose the answer.Marc Sent from my BlackBerry® wireless deviceFrom: "Viktoriia" <dentist_8406@...>Date: Sat, 27 Mar 2010 20:24:09 -0000< >Subject: TMJ disorder test?? >> Hi..> > Can anyone help me with this Q please> > A 45 year old patient attends the dental clinic complaining of a clicking jaw.
