Temporomandibular disorders (TMD) are primarily characterized by pain as well as disorders concerning the proper functioning of individual elements of the stomatognathic system (SS). The aim of the study was to compare the degree of relaxation of the anterior part of the temporal muscles and the masseter muscles, achieved through the use of post-isometric relaxation and myofascial release methods in patients requiring prosthetic treatment due to temporomandibular joint disorders with a dominant muscular component. Sixty patients who met the inclusion criteria were alternately assigned to one of the two study groups, either group I—patients received post-isometric relaxation treatment (PIR), or group II—patients received myofascial release treatment (MR). The series of ten treatments were performed in both groups. The comparative assessment was based on physiotherapeutic examination, a surface electromyography (sEMG) of the anterior temporal and masseter muscles and the intensity of spontaneous masticatory muscle pain, assessed using the Visual Analogue Scale (VAS). We observed a significant decrease in the electrical activity of examined muscles and a significant drop in the intensity of spontaneous pain in the masticatory muscles both in group I and II. There were no significant differences between groups. Both therapeutic methods may be used as successful forms of adjunctive therapy in the prosthetic treatment of TMD. The trial was registered with an international clinical trials register.

BACKGROUND: Preservation and strengthening of the health of civil aviation flight personnel is an extremely urgent problem and is associated with ensuring flight safety. AIM: This study aimed to determine the structure and analyze the organs and tissues of the masticatory apparatus among civil aviation flight personnel. MATERIALS AND METHODS: To determine the incidence and intensity of main dental diseases and the morbidity structure of organs and tissues of the masticatory apparatus in civil aviation pilots, an in-depth examination was carried out in 120 men aged 2545 years (study group 1) working on various modern passenger and transport aircrafts. The duration of flight operations ranged from 2 to 17 years, with a total flight duration of 140 to 5580 h. The comparison group consisted of 146 men (aged 2545 years) of non-flying specialties (study group 2). The generally accepted methods for assessing the prevalence and intensity of the course of major dental diseases were used. RESULTS: The incidence and intensity of dental disorders, periodontal disease, temporomandibular joint disorders, and parafunctions of the masticatory muscles were defined. The incidence and intensity of major dental diseases among civil aviation flight personnel were clearly directly proportional to their flight time (r=0.547) and duration of work in civil aviation (r=0.482) but to a lesser extent to their age (r=0.416). CONCLUSIONS: Non-carious lesions of the teeth, inflammatory and dystrophic diseases of the periodontal and oral mucosa, painful dysfunction of the temporomandibular joint, and bruxism are more common among civil aviation flight personnel than among non-flying personnel, which is due to the unfavorable effect of air flight factors on organs and tissues of the mastication apparatus and the body of the pilots as a whole.

The article presents a clinical case of the diagnostics and treatment of the temporomandibular joint dysfunction (TMJ) in patient after orthodontic treatment. The hypertonia of masticatory muscles, limit of mouth opening and deviation of the jawbone to the right were observed during physical examination. Adhesion of the disk to the articular tubercle of the right temporal bone was detected on MRI. Hyperrotation of the articular head and the deviation of the jawbone to the right were observed on the charts during axiography. Disappearing of the feeling of heaviness in the right TMJ, free mouth opening, absence of deviation symptom, and the reduction of the rigidity of the masseter muscles were observed on the basis of diagnostic examinations after treatment. Presented clinical experience lets us make a conclusion that it is necessary to prescribe taking axiography and MRI during diagnosing and treating temporomandibular joint dysfunction.

OBJECTIVES The aim is to assess the knowledge, attitude and practice of dental practitioners concerning physiotherapy management of Temporomandibular joint dysfunctions (TMDs.). METHOD 61 dentists were included from Tertiary, secondary and private dental clinics of Karachi, and the study design was cross sectional. RESULTS Prior to survey 45.9% of did not had knowledge about physical therapy management TMD. Maxillofacial surgeons and master’s degree holders had more knowledge about physical therapy (PT) management. 45.9% dentists reported that PT is non-effective treatment approach. Lack of knowledge on dentist’s behalf is the foremost cause of less referral to PT 88.5%. Jaw exercises were prescribed by 83.6% of dentists. In the end of the survey 52.5% dentists were reluctant to refer, 47.5% were maybe they will refer and 96.7% dentists were eager to gain more knowledge about the benefits of PT and collaborative treatment. CONCLUSIONS This study concluded that the dental practitioners of Karachi lack knowledge, attitude and practice regarding physiotherapy treatment of TMD. The benefits of multidisciplinary approach while treating TMDs were not very well known to dental practitioners and its benefits to patients. This study increased the knowledge of surveyed practitioners KEYWORDS Dentistry, Masticatory Muscles, Temporomandibular Joint Disorders, Orthodontics, Temporomandibular Joint, Manipulation

Background: The effects of jaw movement pattern on masticatory activity during chewing remains unclear in chronic temporomandibular joint disorders individuals. Objective: to assess the effect of habitual and non-habitual mastication patterns based upon the activation of the masseter and temporalis muscles in individuals with or without temporomandibular joint disorder (TMJD). Methods: Fifty-four participants (age: 18–44 years) were divided into two groups: the TMJD (n=27) and control (n=27) groups. TMJD was identified using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD). Electromyographic activity of the masticatory muscles was measured during 2 tasks: habitual mastication with parafilm (HM) and non-habitual mastication with parafilm (NHM). MATLAB software was used to process electromyography (EMG) signals. The root mean square, symmetry index (SI%), anteroposterior coefficient (APC%) and torque coefficient (TC%) were determined from the processed EMG signal. Results: Reduced right masseter activation was observed for the TMJD group (p<0.05) during jaw agonist phase. During the jaw agonist phase, all muscles presented with more activation during NHM. Symmetry of temporalis (ST%) and APC% were the lowest for HM. TC% was increased for HM. Conclusion: Habitual and non-habitual mastication differ in masticatory activity during jaw agonist and antagonist phase and TMJD individuals presented a different way to recruit muscles under these circumstances. Non-habitual mastication has a more coordinating and stable motor pattern in masticatory activity and has less variability than habitual mastication to assess masticatory activity.

Temporomandibular joint disorders (TMD) are a common health condition caused by the structural or functional disorders of masticatory muscles and the temporomandibular joint (TMJ). Abnormal mandibular movement in TMD patients may cause pain, chronic inflammation, and other discomfort, which could be relieved by a variety of drugs through various delivery systems. In this study, we summarized commonly used therapeutic agents in the management of TMD as well as novel bioactive molecules in preclinical stage and clinical trials. The emerging therapy strategies such as novel intra-TMJ delivery systems and implants based on tissue engineering are also discussed. This comprehensive review will strengthen our understanding of pharmacological approaches for TMD therapy.

Abstract Introduction: Temporomandibular joint disorders (TMD or TMJD) involve clinical problems and symptoms affecting the temporomandibular joint (TMJ) and associated structures. The temporomandibular joints are anatomically connected to the cervical region, where cervical spine movements occur simultaneously to masticatory muscle activation and jaw movements. Objective: Our study sought to assess the relationship between the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), surface electromyography (sEMG) of the masticatory muscles, posture and cervical flexibility in women with TMD. Method: Fifty women with an average age of 27.0 ± 6.37 years, diagnosed with TMD according to RDC/TMD, were assessed for craniocervical posture, cervical flexibility and sEMG of the masticatory muscles. Results: There were no differences in jaw function limitations, depression, pain level and its interference in work ability and daily activities, posture and sEMG between TMD diagnoses or between muscle classification (p > 0.05). Depression scores were higher among participants with biarticular dysfunction (p = 0.023). The group with bruxism exhibited a higher pain level at assessment (p = 0.001) and a greater reduction in work ability (p = 0.039). Subjects with muscular and mixed TMD showed less cervical rotation to the right when compared with those with articular TMD. Conclusion: There was no difference in posture or sEMG values for TMD diagnoses, joint and muscle dysfunctions and the presence of bruxism. Muscle dysfunction is associated with reduced cervical rotation to the right. Jaw function limitations did not interfere in posture or sEMG and depression was associated with pain.

Background: Temporomandibular disorders (TMD) are a group of pathologies that affect the masticatory muscles, the temporomandibular joint, and related structures and affect more than 25% of the general population. Objectives: This study aimed to demonstrate the effect of ultrasounds (US) plus diclofenac gel 10% (phonophoresis) as a physical therapy available for the management of TMD based on pain amelioration and function recovery. Methods: Prospective quasi-experimental one-group before-after study. Outcome measures consist: (1) pain measured by Visual Analog scale (VAS); and (2) mouth opening by measuring lip to lip distance and interincisal distance in millimeters (mm); evaluated at the beginning/end of treatment. Twenty sessions (1 session per day) of continuous Ultrasound to intensity of 1 W/cm2/1 MHz/5 minutes over the affected joint, with Ultrasound gel (5 mL) and 10% diclofenac gel (5 mL) in a proportion of 1:1 as transducer medium. Results: A total of 50 consecutive patients were analyzed. Phonophoresis protocol was able to improve all outcome measures with a statistical difference. Pain evaluated by VAS was 6.67 ± 0.82 and decreased to 3.48 ± 0.8 points (P = 0.0000). Mouth opening by mean of lip-to-lip distance was 50 ± 8.23 mm that improved to 56 ± 6.2 mm (P = 0.0000) and by mean of interincisal distance was 37.9 ± 7.02 mm and increased to 44 ± 5.5 mm (P = 0.0000). Conclusions: Diclofenac phonophoresis is an effective physical therapy for the management of TMD, evaluated by pain improvement and function recovery.

BACKGROUND Masticatory system is a complex functional unit, primarily engaged in chewing, swallowing and breathing functions, and some parts are involved in taste recognition and determination of food consistency. Sophisticated functional performances of speech and emotional expressions are specifically human qualities. Irregularities in occlusion appears to be the precipitating factor in the pathogenesis of myofascial pain dysfunction syndrome. Tek- Scan III records the bite length, number, distribution, timing, duration and the relative force of each tooth contact. It also records the sequence of occlusal contacts in terms of time and the associated force with each occlusal contact. The aim of this study was to treat masticatory muscle disorders with occlusal equilibration, and compare the efficacy of treatment outcomes between selective grinding and stabilization splints using Tek-Scan III. OBJECTIVE Objective of this study was to compare the efficacy of occlusal equilibration achieved through selective griding and stabilization splints using Tek-Scan III. METHODS In this in vivo study, 40 patients with masticatory muscle disorders were selected based on the inclusion and exclusion criteria. The occlusal discrepancies were analyzed using Tek-Scan III. The selected 40 subjects were then randomly divided into 2 groups based on the treatment they recieved; Group I – Selective grinding group (20) and Group II – Stabilization splint group (20). Comparison of pre-treatment and post treatment results were evaluated in terms of pain, mouth opening, left and right side force percentage as recorded through Tek-Scan III and reduction of disclusion time. Statistical analysis was carried out with Kolmogorov Smirnov test, Wilcoxon matched pair test and Mann-Whitney U test. RESULTS Wilcoxon matched pairs test demonstrated that there was statistically significant results ( p = 0.0007) in both the groups for reduction of disclusion time, elimination of pain and improved mouth opening. Patients in Group I showed better results as compared to Group II in terms of disclusion time, pain and mouth opening. CONCLUSIONS Occlusal equilibration brought about by reducing the disclusion time using the Tek- Scan III reduced the symptoms of pain in masticatory muscles. Patients in group I (Selective grinding) however showed better results when compared to patients in group II (Stabilization splints).
