Objective: The aim of the study is to determine association between depressive symptoms and the electrical activity of muscles in maximum voluntary clench in a group of young adults.
Methods: A total of 186 volunteers (Females = 98, Males = 88), with a mean age of 19 years, were recruited to the study. All participants took a questionnaire survey stating the level of depression (Beck's scale), clinical examination, and instrumental diagnostics (EMG).
Results: Symptoms of mild or medium depression were found in 35 of the subjects (18.82%). Average electric potentials of the masticatory muscles in maximal voluntary clench were significantly higher among the subjects with depression symptoms in comparison with subjects without those symptoms (85.96 ± 10.25 vs 78.97 ± 15.32, p < . 0.05).
Discussion: An increase in the electrical potentials of masseter muscles in maximal voluntary clench was found in the group with depression symptoms. The study should be continued to confirm this finding.

Objective: To assess the dynamic mandibular movement of patients with condylar hyperplasia before and after simultaneous orthognathic surgery and condylectomy through an intraoral approach.
Methods: Two groups of patients diagnosed with unilateral condylar hyperplasia were studied: the preoperative group consisted of 23 patients and the postoperative group consisted of 13 patients who had undergone simultaneous orthognathic surgery and condylectomy through an intraoral approach with follow-up for more than 1 year. The normal reference value was obtained from 11 individuals without oral and maxillofacial diseases.

The objective of the study was to assess the utility and safety of Temporo-masseteric Nerve Block (TMNB), and to explore the mechanism for its apparent sustained pain relief. This manuscript describes, (1) a retrospective study evaluating pain reduction in patients who received the TMNB injection for the management of masticatory myogeneous pain (myalgia, per Diagnostic Criteria for Temporomandibular Disorders (DC/TMD criteria)), and (2) a motor nerve conduction study (NCS) of the temporalis and masseter, performed in the absence of signs or symptoms of TMD, before and after the TMNB injection. The results were as follows.

The simultaneous occurrence of primary headaches and temporomandibular disorders can pose a challenge in determining the best clinical management of patients. Therefore, we aimed to summarize evidence regarding the risk and prevalence of temporomandibular disorders (TMDs) in migraine and tension-type headaches (TTH) patients. Cross-sectional studies published in English comparing the presence of TMDs in adults with TTH or migraine to subjects without headaches were included, International Classification of Orofacial Pain, Diagnostic Criteria for Temporomandibular Disorders or Research Diagnostic Criteria for Temporomandibular Disorders, and large epidemiological studies (sensitive diagnostic criteria (SDC)).

The aims of the study are to analyze the influence of pain and no pain expectations on the physiological (electromyography (EMG) and pupillometry) and cognitive (Numerical Rating Scale (NRS)) response to pain. Pain expectation and no pain expectation situations were induced by employing instructional videos. The induction of pain was performed by palpating the masseter with an algometer in a sample of 2 groups: 30 healthy participants (control group) and 30 patients (Temporomandibular disorders (TMD) group) with chronic myofascial pain with referral in the masseter muscle (Diagnostic Criteria for Temporomandibular Dissorders (DC/TMD)).

Temporomandibular disorders (TMD) comprise a group of conditions affecting the masticatory muscles, the temporomandibular joints and associated structures, often manifesting as orofacial pain and functional limitations of the mandible. Central sensitization (CS) is gaining increasing attention in research focused on pain syndromes and somatization, playing a significant role in the pain experience. This study investigates the prevalence of CS and somatization among TMD patients, analyzing their relationships with TMD diagnoses and the intensity of chronic masticatory muscle pain (MMP).
