“…This is in contrast to the results reported by Tallents et al, who did not perform any MRI to confirm his EVG diagnosis. 30 Furthermore, several MRI studies of adults have demonstrated disc displacement in about one-third of volunteers with no symptoms. [31][32][33][34] On the basis of the results of our study, the role of EVG in supporting the clinical diagnosis of ADDw/oR is of limited value.…”

Objectives: The aim of this study is to evaluate the diagnostic concordance of MRI and electrovibratography (EVG) of the temporomandibular joint (TMJ) in the diagnosis of articular disc displacement with reduction (ADDwR) and articular disc displacement without reduction (ADDw/oR). Methods: 50 patients (12 males, 38 females; mean age 37.46 6 15.64 years) with a hypothesis of disc displacement were selected. For each patient an MRI of the TMJ was performed. MRIs were evaluated sorting the 100 TMJs by kind of pathology (no pathology, ADDwR, ADDw/oR, and joint hypermobility). Afterwards, the patients had an EVG exam. The EVG exams were performed with vibration transducers over each TMJ, enabling simultaneous, bilateral recording of vibrations emanating from joint sounds during the opening and closing movements. The presence of a sound peak was compared with the MRI diagnosis of ADDwR, while a multipeak aspect was compared with ADDw/oR diagnosis using Cohen's kappa test. Results: The presence of a peak-shaped track has high specificity for ADDwR (90.27%). The Cohen's kappa calculated for the ADDwR was 0.5615 (good-moderate). The presence of a multipeak-shaped track has low specificity (65.22%) and sensitivity (70.42%). The Cohen's kappa calculated for the ADDw/oR was 0.2992 (poor). Conclusions:The present study recommends the use of EVG to support the clinical diagnosis of a disc displacement with reduction when MRI is not available or when subjects cannot be investigated by MRI.

TMJDs (Temporomandibular joint disorders) are a common pathology but best treatment remains unclear. The goal of this study was to evaluate the effectiveness of mesotherapy on TMJD. We conducted a case review of all TMJD patients treated since 2006 with mesotherapy procedures only and using a cocktail of drugs composing of lidocaine, piroxicam and pentoxifylline. Patients were treated every 15 days until symptomatic relief was achieved and thereafter every two months. Main outcome was complete symptomatic relief, and associated factors were analysed. 27 patients were included. Complete pain relief was achieved in 26. The necessary number of procedures to get pain relief ranged from 1 to 6 (median of 1) and the total number of treatments from 1 to 40 (median of 11). 19 patients had other painful complains mainly related with anxiety disorders. A weak correlation (r = 0.357; p = 0.05) between anxiety disorders and the required months of treatments was found. Mesotherapy is a valuable option on pain relief in a temporomandibular pain syndrome with none of the systemic effects of oral medication. Anxiety may have a role on the aetiology and therapeutic success highlights the holistic approach of these patients. Future comparative studies are necessary.

“…Normal joints produce very little friction and vibration. If there is degeneration in the joint, there is sound in the joint [44][45][46][47]. The sound spectrum may be bigger or less than the human hearing limits.…”

“…Generally, spectral analysis considers the problem of determining the spectral content (i.e., the distribution of power over frequency) of a time series from a finite set of measurements, by Sounds due to temporomandibular joint disorders have been studied for a long time and are classified to the particular groups [45,47,[50][51][52]. Very well-known sound frequencies belong to the "click" sound energy ( Figure 3).…”

Temporomandibular Joint Pathology - Current Approaches and Understanding

Temporomandibular joint disorder (TMJ) is a complex and multifactorial functional disorder. Best approach in the treatment of TMJ disorders needs in detail proper diagnostic study. Joint vibration analysis (JVA) device, a new age technology and one of the most important diagnostic tools, is used for detecting intra-articular sound vibrations. Every type of vibration in different frequencies shows us the status of joint. Evaluation can be made after analyzing the results applying to a diagram. Like Combining of the sound vibration diagnostic techniques with other examination methods may be very meaningful in efforts of treating TMJ problems. Another diagnosis method is the evaluation of chewing movements. Best chewing efficiency is the most important purpose of masticatory system. Final product is a very important indicator for the efficiency of the mastication, and chewing pattern. T-Scan digital occlusal analyzing system is another important occlusal diagnostic instrument. Digital occlusal analysis system is currently the most powerful method of TMD clinics for treatment of patients with muscle pain dysfunction syndrome. Digital occlusal analysis system allows us to perform the MPDS treatments, splint and occlusal rehabilitation. The three important diagnostic systems are described in this chapter.
