“…In the literature, studies using the the FAI report the TMD rate between 42% and 73% [7,34]. The variability in prevalence may be due to factors such as the variability of the number of samples used in the studies and the period in which the study was conducted.…”

Objective: This study aimed to examine the association between sleep quality, depression, anxiety and stress levels, and the frequency of temporomandibular disorders in a sample of Turkish dental students during the COVID-19 pandemic. Methods: The current cross-sectional study was conducted with 699 dental university students during the COVID-19 pandemic. Fonseca Anamnestic Index (FAI), Pittsburgh Sleep Quality Index (PSQI), and Depression Anxiety Stress Scale-21 (DASS-21) were used in the present study. Results: The incidence of temporomandibular joint disorders in the present study was found to be 77.5%. Female students' FAI scores were found to be statistically significantly higher than males (p < 0.05). Additionally, higher depression and anxiety and stress levels caused increased PSQI and FAI scores. Conclusion: During the COVID-19 pandemic, increased temporomandibular joint disorders were observed with increased impaired sleep quality and higher depression, anxiety and stress levels among dental university students.

“…The sEMG signals were amplified and filtered (Butterworth 4th order, 20–450 Hz bandpass filter, 60 Hz notch filter). All information was recorded and processed using Miotec Suite ® software (Miotec Biomedical Equipments, Porto Alegre, RS, Brazil) [ 7 , 8 , 18 ]. Before placement of the sEMG electrodes, the skin was cleaned with 70% alcohol to remove fatty residues, followed by exfoliation with a special sandpaper for the skin and a second cleaning with alcohol.…”

“…Before placement of the sEMG electrodes, the skin was cleaned with 70% alcohol to remove fatty residues, followed by exfoliation with a special sandpaper for the skin and a second cleaning with alcohol. As the TM and M electrodes’ locations were not described in the Surface Electromyography for the Non-Invasive Assessment of Muscles (SENIAM) site ( , accessed on 25 June 2021), the electrodes were placed on both the left and right sides, according to previous studies’ descriptions [ 7 , 8 , 18 ].…”

Masticatory Myoelectric Side Modular Ratio Asymmetry during Maximal Biting in Women with and without Temporomandibular Disorders

et al. 2022

There is no consensus on the role of electromyographic analysis in detecting and characterizing the asymmetries of jaw muscle excitation in patients with temporomandibular disorders (TMD). To analyze the TMD patients (n = 72) in comparison with the healthy controls (n = 30), the surface electromyography (sEMG) of the temporalis anterior muscle (TA) and masseter muscle (M) was recorded while a maximal biting task was performed. The differences in the asymmetry of the relationship between the masseter muscles were assessed in a module to determine the sensitivity (Sn) of binomial logistic models, based on the dominance of the TA or the M muscle, in accurately predicting the presence of TMD. All assumptions were met, and comparisons between the groups showed significant differences for the TA muscle ratio (p = 0.007), but not for the M muscle ratio (p = 0.13). The left side was predominant over the right side in the TMD group for both the TA (p = 0.02) and M muscles (p = 0.001), while the non-TMD group had a higher frequency of the right side. Binary logistic regression showed a significant model (χ2 = 9.53; p = 0.002) for the TA muscle with Sn = 0.843. The model for the M muscle also showed significance (χ2 = 8.03; p = 0.005) with Sn = 0.837. The TMD patients showed an increased TA muscle ratio and asymmetry of left dominance, compared to the healthy subjects. Both of the binomial logistic models, based on muscle dominance TA or M, were moderately sensitive for predicting the presence of TMD.

“…Because of an undefined etiology, the diagnosis must be made carefully through detailed anamnesis and physical examination with muscle verification through palpation. There are other resources that aim to improve the acquisition of data relevant to treatment, such as the diagnostic criteria (DC/TMD) requiring standardized evaluation of signs and symptoms (Portinho, et al, 2012;Fassicollo, et al, 2017;Klasser, et al, 2017;Girasol, et al, 2018). DC/TMD is composed of two axes: physical diagnosis (Axis I) and psychosocial diagnosis (Axis II).…”

Prevalence of cervical alterations in patients with temporomandibular dysfunction in a specialized referral service

The muscular structures of the body are interconnected, with the cervical and masticatory systems forming a part of the complex called Manducatory System, which is a part of the organic postural system. Alterations in one of these components induce compensatory changes and affect other systems. These adjustments can lead to temporomandibular dysfunction (TMD) and craniocervical dysfunction. Their etiology is multifactorial, with a high prevalence of chronic pain, especially in cases of headaches. Cervical alterations are common in TMD, considering the degree of pain and discomfort experienced by patients. This study aimed to conduct a survey of medical records regarding the frequency of TMD with cervical changes in patients who visited our institution between 2017 and 2019. Approximately 81.86% of patients showed cervical changes, and the sternocleidomastoid muscle showed the greatest involvement, especially in the mastoid portion. TMD showed greater involvement in women and was most prevalent between 40-49 years of age. This study contributes to scientific literature, since there are few reports highlighting the need to promote research and financial support in this subject area, which can help improve the diagnosis and treatment of these craniocervicomandibular disorders.
