“…Pressure Pain Thresholds.-Pressure pain thresholds (PPTs) 48 were measured with a real-time feedback electronic pressure algometer (Algomed, Medoc, Israel), with a rubber tip measuring 1 cm 2 , at both trigeminal (bilateral superficial masseter muscles and bilateral anterior temporalis muscles) and extratrigeminal regions (bilateral thenar muscles in the palmar side of the hands). 9,49 PPTs were measured to determine whether participants with chronic mTMD had abnormal thresholds, which could indicate the presence of hyperalgesia and/or allodynia.…”

“…For the thenar muscle, PPTs were measured on the thenar eminence located on the palmar side of the hand, as previously done. 9,49 For all measurements, the algometer was positioned perpendicular to the skin. A single trained operator (TVI) placed the algometer tip on the respective site and applied pressure at a constant rate of 20 kPa/seconds using visual feedback provided by software (Medoc Main Station, ver.…”

“…After the baseline psychophysical measurements, participants in both the mTMD and control groups underwent a music pretest, which served to select music pieces for the GML experiment, as done previously. 49 During the 60-minute GML experiment, participants were submitted to four 15-minute auditory blocks including pink noise (an auditory signal with a constant power spectral density), and 3 different music playlists including stressful, relaxing, and favorite music pieces, respectively. All auditory blocks were administered in random order.…”

“…After each block, participants reported their perceived stress and relaxation levels using two 100 mm VAS, with the anchors "no relaxation" and "maximum relaxation" and "no stress" and "maximum stress." Participants also scored their music experience on 3 additional 100 mm VAS scales developed by a musicologist (MT), 49 to measure different dimensions of the perceptual music experience: (1) intensity of physical activation ("Rate the intensity of your physical activation during the music task"; left anchor: "no physical activation"; anchor: "maximum physical activation");…”

Objective In this experimental study, we aimed to determine whether guided music listening (GML) – a music intervention based on models of mood mediation and attention modulation – modulates masticatory muscle activity and awake bruxism in subjects with chronic painful muscular temporomandibular disorders (TMD myalgia, mTMD), a condition causing a significant burden to patients, their families, and healthcare systems. Background Awake bruxism – a stress behavior characterized by clenching of the teeth – is a strong contributor to chronic mTMD. GML modulates psychological stress and motor responses and could thus reduce muscle activity in chronic musculoskeletal conditions, including mTMD. Methods We recorded the electromyographic (EMG) activity in the right masseter of 14 women with chronic (>6 months) mTMD (median [IQR] = 39.5.3 [24.3] years) and 15 pain‐free women (median [IQR] = 30.0 [3.5] years) during a GML session, including 3 music (stressful, relaxing, and participants' favorite music) and a no‐music (pink noise) control blocks, each lasting 15 minutes. We measured the motor effort of the right masseter relative to the participants' maximum voluntary contraction (MVC), the muscular effort to maintain mandibular posture (EMGposture), and to produce spontaneous awake bruxism episodes (EMGbruxism), and the duration and frequency of spontaneous awake bruxism episodes. We tested between‐group and within‐group (between blocks) differences, as well as the effect of the interaction group by experimental block on these outcome measures. Results In both groups, EMGposture was significantly affected by the interaction group by experimental block (P < .001). Compared to pink noise [mean (95% CI); mTMD: 2.2 (1.6‐2.8) %MVC; Controls: 1.1 (0.5‐1.7) %MVC], EMGposture increased during the stressful music block [contrast estimate (95% CI); mTMD: +0.8 (0.7‐0.8) %MVC; Controls: +0.3 (0.3‐0.4) %MVC; both P < .001], and decreased during the relaxing [mTMD: −0.4 (−0.5 to −0.4) %MVC; Controls: −0.3 (−0.4 to −0.3) %MVC; both P < .001] and favorite [mTMD: −0.5 (−0.6 to −0.5) %MVC; Controls: −0.5 (−0.5 to −0.4) %MVC; both P < .001] music blocks. EMGposture was greater in mTMD individuals than controls during the favorite music [contrast estimate (95% CI): +1.1 (0.2‐1.9) %MVC; P = .019] and the pink noise [+1.1 (0.2‐2.0) %MVC; P = .014] blocks. EMGbruxism was significantly affected by the interaction group by experimental block (P < .001). In mTMD participants, compared to the pink noise block [mean (95% CI); 23.8 (16.0‐31.6) %MVC], EMGbruxism increased during the stressful music block [contrast estimate (95% CI); +10.2 (8.6‐11.8) %MVC], and decreased during the relaxing [−6.2 (−8.1 to −4.3) %MVC; P < .001] and favorite [−10.2 (−12.2 to −9.1) %MVC; P < .001] music blocks. These effects were not observed in the control group [mean (95% CI); pink noise: 19.3 (10.9‐27.6); stressful: 21.2 (12.9‐29.4) %MVC; relaxing: 21.6 (13.3‐29.9) %MVC; favorite: 24.2 (15.8‐32.7) %MVC; all P > .05]. EMGbruxism was significantly greater in mTMD partici...

“…The activity of the muscle by the clenching causing temporomandibular disorder decreases when participants hear favorite music. To hear the favorite music or relaxing music decreases the level of the stress and increases the pleasure intensity [ 97 ]. Many cultures throughout history have relied on music to cure physiological or psychological ills.…”

Although the connections between neuropsychiatric and dental disorders attracted the attention of some research groups for more than 50 years now, there is a general opinion in the literature that it remains a clearly understudied and underrated topic, with many unknowns and a multitude of challenges for the specialists working in both these areas of research. In this way, considering the previous experience of our groups in these individual matters which are combined here, we are summarizing in this minireport the current status of knowledge on the connections between neuropsychiatric and dental manifestations, as well as some general ideas on how oxidative stress, pain, music therapy or even irritable bowel syndrome-related manifestations could be relevant in this current context and summarize some current approaches in this matter.
