Objective: The purpose of this study was to evaluate the effects of Rocabado's 6 × 6 exercises on masseter muscle thickness, muscle elasticity, and pain scores in patients with bruxism.
Methods: A total of 58 participants with bruxism were divided into 2 groups as the exercise group (EG) and control group (CG). A self-care program was applied for the participants in the CG. For those in the EG, in addition to the self-care program, an exercise treatment was performed for 6 days per week for a total of 8 weeks. Using ultrasonography, bilateral masseter muscle thickness and elasticity were assessed before and after treatment. Pain was measured using a visual analog scale. Changes over time within the groups and group-time interactions for continuous variables were assessed using mixed 2-way repeated measures analysis of variance.
Results: The improvement in muscle elasticity (P = .015; P = .004) and pain values (P = .049; P = .040) were greater in the EG compared with the CG. There was no significant difference between the 2 groups for masseter muscle thickness (P > .05).
Conclusion: This study suggests that Rocabado's 6 × 6 exercises are effective in the treatment of muscle elasticity and pain values in participants with bruxism.

Background: This study aimed to evaluate the effects of 4-hexylresorcinol (4HR), a synthetic compound with antioxidant and stress-modulating properties, on diabetic sarcopenia in the masseter muscle.
Methods: A controlled, parallel-arm study was conducted using 38 Sprague-Dawley rats divided into diabetic and non-diabetic groups. Diabetes was induced with streptozotocin (STZ), and the groups were further subdivided to receive weekly subcutaneous injections of either 4HR or saline.

Objective: To compare the ultrasonographic characteristics of masseter muscles in temporomandibular disorder (TMD) subjects with a diagnosis of myalgia of the masticatory muscles to a control population.
Method: In total, 45 TMD subjects with masseter muscle myalgia according to the Diagnostic Criteria for Temporomandibular Disorders were compared with 45 control subjects. The masseter muscles of each subject were examined by ultrasonography (US) to assess the quantitative characteristic of local cross-sectional dimension (LCSD) and the qualitative parameters of intramuscular ultrasonographic appearance, anechoic areas, and isoechogenic areas.

Background: Bilateral trigeminal neuralgia secondary to multiple sclerosis is an extremely rare condition. When Gasserian ganglion block is performed, it is necessary to achieve reliable long-term analgesic effects while avoiding treatment-related complications.
Case Presentation: A 49-year-old male with multiple sclerosis exhibited persistent dull pain and paroxysmal electric shock-like pain in his bilateral maxillary molars and mandible.

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 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)).
