Opis:
Introduction: Multifactorial aetiologies of painful temporomandibular disorders (TMD) have an impact on correct diagnosis and consequently prevent proper treatment. Aim of the study: The aim of the study was to evaluate the effect of magnetic stimulation on electromyographic activity in temporal muscles and masseters in patients using occlusal splints. Materials and methods: The examined group consisted of 40 edentulous patients with TMD. The patients were examined based on Helkimo Index. Next, electromyographic activity of the temporal muscle and masseter were investigated using 8-channel surface electromyography. All patients received acrylic occlusal splints for 12 weeks. The group qualified for the study included 20 randomized patients, whose therapy was additionally carried out by extremely low-frequency magnetic fields for a period of 21 days. Following examinations were conducted after 3, 6 and 12 weeks with surface electromyography recording of the examined muscles. Patients received occlusal splint corrections using the T-Scan III system. The clinical evaluation of TMD was analysed using Helkimo index and VAS scale before and after the treatment. All the data were analysed using Statistica 12.5 PL. Results: Patients with combination therapy had lower asymmetry of temporal muscle activity. Conclusions: Combination therapy using magnetic stimulation reduced intensity of pain in patients with TMD and decreased values of the Helkimo indices.

Objectives This study investigated whether playing wind instruments has adverse effects on musculoskeletal functions among junior high school students who play in music clubs. Material and Methods The study included 210 junior high school students (35 boys, 175 girls) belonging to 1 of 4 different school clubs that practiced playing wind instruments more than 6 days/week. The mean age of the participants was 14 years. The study was performed using a questionnaire survey and an electromyographic examination of jaw and cervical muscle activities during playing wind instruments. Results The prevalence of temporomandibular disorders (TMD) among the children playing woodwind (WW) or brass wind (BW) instruments was higher than in those playing non-wind (NW) instruments. Long duration of playing WW with a reed mouthpiece or BW with a small mouthpiece was suggested to affect the incidence of TMD, which was more marked in girls than in boys, irrespective of height or weight. Muscle activity in the masseter muscle during playing an instrument was significantly higher in the BW with a small mouthpiece group than in the NW group (p < 0.05). In cervical muscles, muscle activity of both the sternocleidomastoid and trapezius muscles was higher during playing BW than in the case of other instruments, and activity in the sternocleidomastoid muscle was significantly higher in the BW with a small mouthpiece group than in the case of other instrument groups (p < 0.05). Conclusions Playing wind instruments may have adverse effects on musculoskeletal functions among junior high school students playing in music clubs as compared with playing NW instruments. The prevalence of TMD among the students playing wind instruments was higher than in those playing other instruments. Long duration of playing those instruments affects musculoskeletal function, and this effect is more marked in girls than in boys, irrespective of height or weight.

Opis:
Purpose: This study aimed to analyze the changes of the stress distributions in TMJs for the pre- and postoperative patients with mandibular prognathism under unilateral occlusions, a frequent occlusion in mastication. Methods: Pre- and six-mouth postoperative cone-beam computed tomography images of thirteen patients diagnosed with mandibular prognathism were scanned and used to construct complete maxillofacial models, assigned as the Pre and Post group, respectively. Another ten asymptomatic individuals were defined as the Control group. The inhomogeneous properties were assigned to the models. The muscle forces and boundary conditions corresponding to left and right unilateral occlusions were applied on the models. The analysis of variation (ANOVA) was chosen for the comparison among the groups. Results: The results showed that the Pre group had abnormal stress distributions ang higher stress level in TMJs, compared with those of the Post and Control groups. Moreover, from clinical cases, symptoms of temporomandibular disorders (TMDs) always followed with increased stresses. Conclusion: Generally, orthognathic surgeries could improve the stress distribution in TMJs of the patients with mandibular prognathism under the unilateral occlusions. However, the postoperative complications, especially symptoms of TMD, were closely related to changes of stress for patients with mandibular prognathism after orthognathic surgeries. Individual virtual surgery and finite element analysis should be conducted to prevent complications in TMJ.

Opis:
Temporomandibular joints are part of the stomatognathic system and play an important role in chewing, swallowing and speech articulating and expressing emotions. Unfortunately, they often do not work properly. Occasional disorder, postural defects, increased muscle tone bearing down due to stress deprivation through such parafunctions as clenching and grinding teeth, long-term chewing gum, nail biting or chewing lips and cheeks can lead to the appearance of dysfunctions in the temporomandibular joints. Analysis of vibrations caused by dysfunctions enables a more accurate diagnosis and an objective way of monitoring the treatment process. The article presents the results of pilot studies carried out in this area by Authors on a group of 13 people (9 women and 4 men) suffering from various diseases within the stomatognathic system. Particular attention was paid to the problems associated with vibroacoustic registration of temporomandibular joint cracks that occurred during the determination of the test methodology.
Stawy skroniowo-żuchwowe są elementem układu stomatognatycznego i pełnią ważną rolę w procesach żucia, połykania, artykulacji dźwięków i wyrażania emocji. Zaburzenia okluzyjne, wady postawy ciała, wzmożone napięcie mięśni unoszących żuchwę spowodowane rozładowywaniem stresu przez takie parafunkcje jak zaciskanie i zgrzytanie zębami, długotrwale żucie gumy, obgryzanie paznokci czy przygryzanie warg i policzków mogą doprowadzić do pojawienia się dysfunkcji w obrębie stawów skroniowo-żuchwowych. Artykuł przedstawia efekty badań pilotażowych przeprowadzonych w tym obszarze przez Autorów na grupie 13 osób (9 kobiet i 4 mężczyzn) cierpiących na różne schorzenia w obrębie układu stomatognatycznego. Szczególną uwagę zwrócono na problemy związane z wibroakustyczną rejestracją trzasków stawów skroniowo-żuchwowych, które pojawiły się podczas ustalania metodologii badań.

Opis:
The aim of this study was to axiographically analyse the mobility of the condyles of the temporomandibular joints in patients with partial edentulism in lateral sections and try to specify whether the partial edentulism has an impact on the severity of temporomandibular disorders. 60 subjects with partial edentulism (different range groups) and 20 subjects in the control group (full dental arches) were examined. Every patient underwent a thorough clinical examination, including axiography conducted by means of Cadiax Compact II® system. The results show some correlation between the advancement of temporomandibular joint disorder, the range of partial edentulism and the abrasion of the residual teeth. In the study, a significant intensification of dysfunction symptoms and restricted condylar path was observed in patients with the largest partial edentulism and significant level of tooth wear of the residual teeth. A significantly higher percentage of asymptomatic subjects or those with minor dysfunction was also found among the patients with lowest-range partial edentulism in lateral sections.
