Correlation between Clinical Features and 3 T Mri Findings of Disc Position Status in Patients with Internal Derangement of Temporomandibular Joint

Zeinab Ghadhanfer Hammod, Lamia H. Al – Nakib, Raad H. Abed Tawfeq


Background: Internal derangement is defined as an abnormality in the articular disc position and sometimes its’ morphology that
may interfere with normal function. The aims of study was to correlate between the clinical signs and symptoms and 3 Tesla magnetic
resonance imaging findings of the articular disc position in patients with internal derangement of temporomandibular joint.
Materials and methods: A total forty six (30 study and 16 control) participants aged between18 and 49 years, were examined
according to Helkimo clinical dysfunction index scoring criteria which include clinical examinations of the range of mandibular
mobility, impaired TMJ function, muscle pain ,TMJ pain and pain during mandibular movement.
Results: There is statistically high significant difference between Helkimo clinical dysfunction index in the cases group (with temporomandibular
joint disorders) and controls group with MRI findings of disc position, that as the severity of index increased, there
were progression of disc displacement and shows positive association expressed by significant probability (p) value.
Conclusion: There is a significant correlation between Helkimos’ clinical dysfunction index and MRI findings in patients with internal
derangement of temporomandibular joint.
