“…It is a versatile precision instrument used to accurately measure point-to-point distances. According to a study by Norman et al [ 34 ], when the MMO was measured using vernier calipers, it was 0.97 in intrasession and 0.97 in intersession.…”

The purpose of this study was to compare the muscle thickness and tone of the masseter and sternocleidomastoid (SCM) muscles and maximum mouth opening (MMO) in subjects with and without temporomandibular disorders (TMD), and perform a correlation comparison on the results of the TMD group. Sixty patients were allocated to the TMD group (n = 30) or the non-TMD group (n = 30). Ultrasound imaging, myotonometer, and vernier calipers were used to determine the related changes in muscle thickness and muscle tone in masseter and SCM, and MMO, respectively. The TMD group revealed a significant decrease than the non-TMD group in the muscle thickness of masseter and SCM, respectively (p < 0.001), with a significant increase in frequency (p < 0.001) and stiffness (p < 0.001) in the masseter muscle tone, with a significant increase in frequency (p < 0.001) and stiffness (p = 0.005) in the SCM muscle tone, a significant decrease in the MMO (p < 0.001). There was a moderate negative correlation between the relaxed state of masseter muscle thickness and stiffness of SCM muscle tone (r = −0.40, p = 0.002), and a moderate negative correlation between the relaxed state of SCM muscle thickness and frequency of SCM muscle tone (r = −0.42, p = 0.001). There was a moderate negative correlation between the clenching state of SCM muscle thickness and the frequency of SCM muscle tone (r = −0.47, p < 0.001). In addition, a moderate negative correlation between MMO and frequency of SCM muscle tone (r = −0.44, p < 0.001). The muscle thickness was decreased, and the muscle tone was increased in the masseter and SCM muscle, respectively. Additionally, MMO was decreased in patients with TMD compared with non-TMD.

“…This procedure was chosen to both automate and secure the data collection thus preventing the risk of data loss. In addition, maximal mouth opening was measured once using a calliper as recommended for both control participants and patients with TMD; 30 this measure was subsequently used for DC/TMD classification of intra‐articular temporomandibular disorders for patients.…”

“…Since pain may have a non‐negligible effect on the measure, the intensity of the pain was recorded by interviewing the participant using a visual analogic scale ranging from 0 ( no pain ) to 10 ( maximal imaginable pain experienced ). In addition, maximal mouth opening was measured once using a caliper as recommended for both control participants and patients with TMD (Best et al, 2013 ); this measure was subsequently used for DC/TMD classification of intra‐articular TMD for patients.…”

Background Temporomandibular disorder (TMD) perturbs the tongue motor control and consequently impairs oral function, but strength training reduces this impairment. However, tongue motor control is widely reduced to a matter of strength. Objectives To investigate the accuracy of the tongue placement as a measure of tongue motor control in patients with TMD compared with age‐ and sex‐matched healthy participants. Material and Methods This proof‐of‐concept case‐control study was prospective, observational, and part of the TMIQ study (NCT04102306). After pointing against a wood stick while maintaining the tongue as sharp as possible, the examinator drew the contour of the tongue print on the wood stick, which was then scanned for image analyses to compute the area for each participant using ImageJ. Results A total of 94 participants were included, all patients with TMD ( n = 47) diagnosed with myalgia, 61% with intra‐articular joint disorder accordingly to the DC/TMD. The median (IQR) tongue print area was 117 (111) mm 2 for the TMD group and 93.5 (76.2) mm 2 for the control group ( V = 352, p = .04) and the median [95% confidence interval] difference was 25.4 [1.3; 51.0] mm². Overlapping of the 95% confidence intervals of the area evidenced no significant difference between the categories of the DC/TMD. The corrected each area–total correlation ( r = .24) suggests a reasonably homogenous thus valid measure. Conclusion The results suggest that TMD impairs the motor control of the tongue. Therefore, the sharpest tongue pointing test may constitute a simple and accessible clinical tool to assess the accuracy of tongue placement in TMD patients. The study was registered on ClinicalTrial.gov with identification number NCT04102306.
