ObjectivesThe aim was to assess the added diagnostic value of ultrasonography (US) for establishing the presence or absence of disc displacements (DDs) in temporomandibular joints (TMJs).Materials and methodsPubmed and EMBASE were searched electronically to identify diagnostic accuracy studies that assessed the diagnostic value of US for the diagnosis of DD, using Magnetic resonance imaging (MRI) as the reference standard. Meta-analyses were performed with Metadisc 1.4 and RevMan 5.3.ResultsA total of 16 studies qualified for meta-analyses. For the diagnosis of DD at closed mouth position (DD-CM) and DD at maximum mouth-opening position (DD-MMO), the added values of a positive result with US for ruling in DD-CM and DD-MMO were 22 and 41%, while those of a negative result with US for ruling out DD-CM and DD-MMO were 30 and 20%. For the diagnosis of DD with reduction (DDWR) and DD without reduction (DDWoR), the added values of a positive result in US for ruling in DDWR and DDWoR were 35 and 41%, while those of a negative result in US for ruling out DDWR and DDWoR were 21 and 27%.ConclusionsUsing MRI as reference standard, the added values of both positive predictive values and negative predictive values of US for ruling in and ruling out DDs are sufficient in the decision-making in dental practice.Clinical relevanceUS can be a good imaging tool to supplement clinical examination findings in patients with suspected DDs. Combined static and dynamic examinations using high-resolution US should be preferred.

“…3 Prior research has related the dimensions of TMJ space, joint morphology and joint pathology to dental occlusion and positional variations of the condyle within the joint. 8,[19][20][21][22]24,[26][27][28][29] Pans have commonly been used to provide an initial assessment of these situations, with minimal limitations. 26,27,29 Hence, Pans remain the prime TMJ diagnostic modality.…”

The articular disc of the temporomandibular joint (TMJ) cannot be seen on plain x-ray examination but an accurate assessment of the space between the glenoid fossa and the head of the condyle may provide the clinician with a clue to a possible pathological problem. Measurements of the TMJ space seen on panoramic radiographs (PAN) and on cone beam computerised tomographic scans (CBCT) were carried out on films taken of of left and right TMJs of forty-six patients. On each image a vertical line was drawn digitally from the highest point of the condylar head to the glenoid fossa of the temporal bone. The lengths of the lines were recorded on Galileo software and compared using the Bland-Altman statistical test (total sample size 92 joints). Bias was achieved at mean differences of 1.03mm with a p-value of <0.001 which was statistically significant. Left and right TMJ mean values showed a 0.09 mm difference. Age was insignificant at p=0.40. The Levels of Agreement indicated workable concord between the methods although a wide range was evident.
