Abstract
Statement of problem : Disc displacement is the most common temporomandibular joint disorder and MRI is the gold standard in diagnosis of disc displacement. This disorder not only affects disc and bony tissue but also inducts inflammation in retrodiscal tissue and lateral ptrygoid muscle and this can lead to changes in signal intensity.
Objectives : The purpose of this study was evaluation of correlation between relative signal intensity of retrodiscal tissue , superior head of lateral ptrygoid muscle and inferior head of ptrygoid muscle in TMD patients.
Material and methods : in this cross-sectional study , 31 MR images of patients who had anterior disc displacement was evaluated. After relative signal intensity measurement for retrodiscal tissue , superior and inferior head of lateral ptrygoid muscle , the correlation between relative signal intensity and type of anterior disc displacement was evaluated.
Results : The correlation between relative signal intensity of MR images and type of anterior disc displacement in retrodiscal tissue ( mean RSI :30.80±29.94 and 13.95± 9.77,p-value = 0.10) , superior head of lateral ptrygoid muscle (mean RSI : 25.30± 23.72 and 29.36± 26.65, p-value= 0.68) and inferior head of lateral ptrygoid muscle (mean RSI : 27.78± 25.55 and 20.82± 19.92 ,p-value=0.40) was not significant. There was also no statistically significant correlation between relative signal intensity of MR images and flattening of condylar head in retrodiscal tissue(mean RSI : 18.07± 12.69 and 21.07± 23.41,p-value=0.75) , superior head of lateral ptrygoid muscle (mean RSI : 21.66± 19.62 and 28.99± 26.37,p-value=0.49) and inferior head of lateral ptrygoid muscle (mean RSI : 20.20± 14.56 and 24.87± 24.73,p-value=0.60).
Conclusion: We found that although MRI is a non invasive procedure in diagnosis of TMD , probably relative signal intensity of MR images in retrodiscal tissue , superior and inferior head of ptrygoid muscle is not a good predictor for type of anterior disc displacement and flattening of condylar head.It seems that this can not be used as a diagnostic marker for TMD progression.

The Congress Reporting Form
How many volunteers were present at the Congress? : 223 participants
Delegates from which countries presented in the congress? : it was an international congress with participants from all 5 continents (USA, UK, Belgium, France, Netherlands, Turkey, Lebanon, Iraq, Japan, Thailand, Nepal,...)
Were the delegates of any other organizations present in the congress? : No
If yes, please write the names of the organizations in the box :  
What were the responses to your talking points? Were specific questions or concerns raised? : My Poster presentation attracted some people and I had a good conversation with them. I handled their question about material and methods and there was also some question about possibility of performing same study with higher sample size.
If you met staff members, please list their full names & positions. : Dirk Schulze, dirk.schulze@ddz-breisgau.de congress scientific department manager
Please inform us if there are any follow up actions we need to talk with the members of the congress : As far as the members of the congress is concerned, I didn't have any issue with them, so there is no need to have any follow up, but I met Dr. White, author of main Dento maxillo facial radiography reference book and he was interested in visiting Iran and have scientific presentation in our Local congress. I transferred the message to TUMS international affairs and they will follow the issue, if they see according possibilities.
Your experiences about the travel processes(Providing ticket, accommodation,...) : I did all my accommodations by myself and seems that there should be some facilities and proper process for booking and accommodations for university staff.
Please give a briefing of your own observations and outcomes of the congress: : It was a highly scientific congress, well organized with a professional congress management. The theme of the congress was “An integrative imaging for dentistry and maxillofacial surgery”. The congress promoted a clinical integrated approach of all imaging techniques used for oral and maxillofacial pathology diagnosis or for treatment planning in dentistry. The congress also provided the latest information and research results in the field of oral and maxillofacial imaging. The pre-congress course entitled “Advances of Maxillofacial Ultrasound” covered all the applications of maxillofacial ultrasound systems, with the opportunities for hands-on experience. The course included state of the art presentations in the field of ultrasound imaging. The congress held at the City Napoca in Cluj-Napoca, the biggest university town in Transylvania, Romania.
