المستخلص : Introduction: Disc ‎displacement with reduction (ADDR) or without reduction (ADD) is considered ‎the most frequent abnormality in ‎patients with pain and dysfunction of the TMJ. Disc ‎displacement is infrequently associated with deformity which ‎has been recognized as ‎an important feature of internal derangement of the TMJ and as a suspect in ‎‎functional impediment. In fact, shape of the disc is one of the determinants of type of ‎surgical procedure ‎selected. The relationship between disc position and configuration ‎has not been fully studied.‎ Objectives: To assess the relationship between different types of disc position and disc ‎configurations in TMJ with ‎internal derangement.‎ Materials and methods: Twenty five patients with clinical diagnosis of internal derangement were examined ‎using T1W sagittal MRI.‎ Displacement and deformity were graded into 6 and 5 ‎classes according to Nebbe and Murakami et al respectively. Relationships between ‎categorical variables were assessed by chi-square and Fisher’s exact tests‎.‎ Results: The most prevalent disc deformity in cases of ADDR was lengthening ‎followed by ‎folding of the disc (28.6%, 23.8%). While the biconcave deformity followed by folding ‎of ‎the disc were the most prevalent in ADD (41.7%, 33.3%). Full disc displacement ‎showed the highest percentage of deformity. However, no statistically ‎significant ‎difference was found between grades of disc displacement and disc configuration.‎ Conclusions and discussion: This study shows no association between disc position and disc configuration in ‎patients with TMJ internal derangement. However, larger sample size and wider ‎range of patients' profile (age and duration of disease) may show otherwise.‎ Introducing Cone-Beam Computed Tomography (CBCT) imaging in Dental ‎Practice ‎Al-Sadhan, Ra'ed, Khan, Emad. Saudi Dental Journal 2008;18(SI)-Abstr.056‎. Presentation at the 2nd KAU & the 19th SDS Conference for Dental Technology & Research and the International Association ‎for Dental Research (IADR) Saudi Arabian Section & General Assembly Meeting. Abstract Cone-Beam Computed Tomography (CBCT) promises to have a great impact on ‎dental procedures. Studies and research in this field are accelerating faster than ‎any previous image modality in our profession. This presentation will cover:  Basics and Imaging Technique. ‎  Multiplaner Reconstruction. ‎  Three dimentional reconstruction. ‎  Volume Rendering.‎  Differences between CBCT and medical multi-detector CT imaging. ‎  Advantages and Applications. ‎  Computer assisted treatment planning and surgical procedure. ‎  Simulation. ‎  Examples of clinical cases where Cone Beam CT Imaging displayed superior data ‎for the referring dentist’s clinical decision.‎
