In recent years, the number of patients applying for prosthetic treatment due to temporomandibular joint disorders (TMD) has been increasing. The main methods for treating disorders are the use of ...occlusal splints and physiotherapeutic rehabilitation as supportive treatment. Radio waves are electromagnetic waves with radiation frequency between 3 Hz and 3 THz, used for physiotherapeutic treatment of skeletal muscle relaxation in the range of 3 to 6 MHz. The rehabilitation effect of these waves is based on diathermy by means of high-voltage quick alternating current. Aim. The aim of the study was to evaluate the influence of radiofrequency waves on the pain of the masticatory muscles in the course of TMD and the usefulness of these procedures in the supporting treatment of these disorders. Materials and Methods. Patients aged 19 to 45 years, of both sexes, reported to the Consulting Room of TMD at the Institute of Dentistry in Krakow to undertake prosthetic treatment of TMD (I a—according to RDC/TMD). Study group (SG) consists of 20 patients who had 10 supportive treatments with radiofrequency currents. In the case of application of radiation to the muscle area, the energy was 20 J to the area of the masticatory muscles, the frequency was 3 MHz, bipolar technique, the duration of the procedure was 10 minutes, and the coupling substance was a gel for ultrasound examinations. The control group (CG) consisted of 20 patients who had 10 supportive treatments with sonophoresis procedures. For the area of masticatory muscles, 0.9 W/cm2 treatments were applied, the duty factor was 80%, the treatment time was 10 minutes, and the medical substance was 25% Voltaren gel. Results. Analysis of the results of the first clinical examinations (axis I) conducted in both groups shows a homogeneous clinical material and similar results. The second clinical examination revealed improved clinical parameters, but it showed a greater improvement in the SG. In the SG, the mean level of VAS was 6.25, and the extreme values were 5.9–0.14, the median was 2.15, and the standard deviation was 1.54. In the CG, the average value of VAS was 6.20 (peak of 5.2–0.7), the median was 2.4, and the standard deviation was 1.87. Summary. The search for new methods of supportive treatment of TMD is an important research direction due to the complex etiology of this disease and the lack of an explicit treatment algorithm. Conclusion. The results of our own research clearly indicate that the use of the radiofrequency waves brings pain relief and improvement of clinical parameters to a greater extent than in sonophoresis. It can be a very important new method in supportive treatment of TMD. Research needs to be continued.
The functional disorders of the masticatory organ are the third stomatological disease to be considered a populational disease due to its chronicity and widespread prevalence. Otolaryngological ...symptoms are a less common group of dysfunction symptoms, including sudden hearing impairment or loss, ear plugging sensation and earache, sore and burning throat, difficulties in swallowing, tinnitus, and vertigo. The diagnostic and therapeutic problems encountered in patients with the functional disorders of the masticatory organ triggered our interest in conducting retrospective studies with the objective of assessing the incidence of otolaryngological symptoms in patients subjected to prosthetic treatment of the functional disorders of masticatory organ on the basis of the analysis of medical documentation containing data collected in medical interviews. Material and Methods. Retrospective study was conducted by analyzing the results of medical interviews of 1208 patients, who had reported for prosthetic treatment at the Functional Disorders Clinic of the Department of Dental Prosthetics of Jagiellonian University Medical College in Cracow between 2008 and March 14, 2014. Results. Otolaryngological symptoms were observed in 141 patients. The most common symptoms in the study group were earache and sudden hearing impairment; no cases of sudden hearing loss were experienced.
Objective. The objective of this study was to evaluate the regression of temporomandibular pain as a result of intra-articular injections of platelet-rich plasma (PRP) to patients with ...temporomandibular joint dysfunction previously subjected to prosthetic treatment. Materials and Methods. The baseline study material consisted of 10 patients, both males and females, aged 28 to 53 years, previously treated due to painful temporomandibular joint dysfunction using occlusal splints. All patients were carried out to a specialist functional assessment of the dysfunction using the Polish version of the RDC/TMD questionnaire axis I and II. Intra-articular injections were preceded by a preparation of PRP. The injection sites were determined by the method used during arthroscopic surgical procedures. Following aspiration, 0.5 mL of plasma was injected into each temporomandibular joint. Results. The comparison of the intensity of pain during all examinations suggests a beneficial effect of the procedure being performed as the mean VAS score was 6.5 at examination I, 2.8 at examination II, and 0.6 at examination III. Conclusion. Application of the intra-articular injections of platelet-rich plasma into the temporomandibular joints has a positive impact on the reduction of the intensity of pain experienced by patients treated for temporomandibular joint dysfunction.
Lack of educational projects in the available literature was an inspiration to develop a psychoeducational program. The objective was to provide patients with basic information on the contribution of ...stressors in the occurrence of temporomandibular joint dysfunction and educate on methods for coping with stress most commonly used in psychology. In the course of three meetings, patients are familiarised with the issue of experienced stress as a potential source of psychosomatic illnesses (in particular, temporomandibular joint dysfunction). Preliminary patients’ opinions, expressed through self-report methods, indicate significant usefulness of the developed psychoeducational program for the process of treatment and the quality of patients’ lives.
Ghrelin, an acylated 28-amino acid polypeptide, was primary isolated from the stomach, and the stomach is a main source of circulating ghrelin. Ghrelin strongly and dose-dependently stimulates ...release of growth hormone from the anterior pituitary, as well as increases food intake and fat deposition. Previous studies showed that ghrelin exhibits protective and therapeutic effect in different parts of the gastrointestinal system, including the oral cavity. The aim of present study was to examine the role of growth hormone and insulin-like growth factor-1 (IGF-1) in the healing of gingival ulcers. Studies were performed on rats with the intact pituitary gland and hypophysectomized rats. In anesthetized rats, chronic ulcers of the gum were induced by acetic acid. Rats were treated intraperitoneally twice a day with saline or ghrelin (4, 8 or 16 nmol/kg/dose) for six days. In pituitary-intact rats, administration of ghrelin significantly increased serum concentration of growth hormone and IGF-1 and this effect was associated with a significant increase in the healing rate of gingival ulcers. Moreover, treatment with ghrelin increased mucosal blood flow and DNA synthesis in the gum, while a local inflammation was decreased what was observed as a reduction in mucosal concentration of pro-inflammatory interleukin-1β. Hypophysectomy decreased serum level of growth hormone below a detection limit; whereas serum concentration of IGF-1 was reduced by 90%. On the other hand, removal of the pituitary gland was without any significant effect on the healing rate of gingival ulcers or on the ulcer-induced increase in DNA synthesis and concentration of pro-inflammatory interleukin-1β in gingival mucosa. Administration of ghrelin failed to affect serum level of growth hormone and IGF-1 in hypophysectomized rats, and was without any effect on the healing rate of gingival ulcers, mucosal blood flow, DNA synthesis or concentration of interleukin-1β in gingival mucosa. Neither induction of gingival ulcers nor hypophysectomy nor administration of ghrelin significantly affected serum concentration of pro-inflammatory interleukin-1β. We concluded that endogenous growth hormone and IGF-1 were involved in the therapeutic effect of exogenous ghrelin in the healing of gingival mucosa damage.
Chronic oral and facial pain syndromes are an indication for intervention of physicians of numerous medical specialties, while the complex nature of these complaints warrants interdisciplinary ...diagnostic and therapeutic approach. Oftentimes, lack of proper differentiation of pain associated with pathological changes of the surrounding tissues, neurogenic pain, vascular pain, or radiating pain from idiopathic facial pain leads to improper treatment. The objective of the paper is to provide detailed characterization of pain developing in the natural history of trigeminal neuralgia and temporomandibular joint dysfunction, with particular focus on similarities accounting for the difficulties in diagnosis and treatment as well as on differences between both types of pain. It might seem that trigeminal neuralgia can be easily differentiated from temporomandibular joint dysfunction due to the acute, piercing, and stabbing nature of neuralgic pain occurring at a single facial location to spread along the course of the nerve on one side, sometimes a dozen or so times a day, without forewarning periods. Both forms differ significantly in the character and intensity of pain. The exact analysis of the nature, intensity, and duration of pain may be crucial for the differential diagnostics of the disorders of our interest.
One of the main etiological factors of the stomatognathic system dysfunction is stress and psychoemotional disorders. During stressful situations, there is an increase in the level of cortisol, the ...so-called stress hormone. Literature data indicate the existence of a correlation between blood cortisol levels and its amount in the saliva. This spurred an inspiration to undertake open, non-randomised studies, the objective of which was to conduct a comparative assessment of the saliva cortisol levels in patients with functional disorders of the masticatory system and in healthy volunteers, as well as to compare the results of cortisol levels with the results of survey-based tests with the use of Endler and Parker's CISS survey. Cortisol level was assessed due to its association with stress present in the body as one of the primary etiological factors of the stomatognathic system dysfunction, and hence the association of elevated cortisol levels assessed in the morning with the occurrence of dysfunctions of the stomatognathic system. The subject of the study is a group of 30 patients, of both sexes, aged between 20 and 46, who reported to the Dental Prosthetic Out-Patient Clinic of the Institute of Dentistry, Jagiellonian University in Cracow, for prosthetic treatment due to the painful form of functional masticatory organ disorders. The control group consisted of 30 subjects, aged between 19 and 41, in whom dysfunctions of the stomatognathic system were excluded. Collection of saliva for testing was performed at a fixed hour (9 am) into plastic test tubes with a stopper. Immediately after collection, the saliva was frozen at the temperature of -18 °C. The assessment of the cortisol levels was conducted by the high performance liquid chromatography (HPLC) with UV detection at the Department of Analytical Chemistry, Faculty of Pharmacy, Department of Laboratory Medicine of the Gdansk Medical University. Moreover, a 20-minute psychological test was conducted with the use of the CISS (coping inventory for stressful situations) survey in order to assess the patients in terms of their abilities to cope with stressful situations. The results obtained were submitted to a statistical analysis based on the conventional calculation procedures. The test group revealed significantly higher cortisol levels compared with the results obtained by the control group. The findings of the CISS survey confirmed the predominance of the emotion-focused strategy of coping with stressful situations in the test group. The results support the view that the psychoemotional factor is, to a considerable extent, conducive to the development of functional disorders. The elevated cortisol levels in patients with psychological disorders concur with the findings by other authors. The results obtained confirm that psychoemotional disorders may be one of the etiological factors of the stomatognathic system dysfunctions. The CISS survey, which was not used in similar studies before, makes it possible to obtain information on the subject's method of coping with stress, thus allowing for the initiation of a relevant psychological therapy aiding the prosthetic treatment.
Auriculo-vestibular symptoms are otolaryngological complaints which frequently co-occur with functional disorders of masticatory organ. These symptoms include: earache, plugged ears sensation, sudden ...hearing impairment, burning pain of the throat, tinnitus, and dizziness. The aim of the study was assessment of co-occurrence of functional disorders of masticatory organ and auriculo-vestibular symptoms, in patients referred for otolaryngological treatment. Forty-two patients aged 24-46 years of both sexes referred for otolaryngological treatment, because of auriculo-vestibular symptoms, were qualified to our study within the framework of research project. After otolaryngological diagnostics (Department of Otolaryngology), these patients were referred for prosthetic consultation to the Department of Dental Prosthetics of Jagiellonian University Medical College. In Otolaryngology Clinic the following specialist examinations were carried out: basic clinical examinations, including otoscopy, tuning fork trials, tonal and verbal audiometry, and tympanometry. These examinations were supplemented with electronystagmometry. On prosthetic consultation, specialist functional investigations of masticatory organ, and electromyographic assessment of the activity of masseter muscles and the anterior part of the temporal muscle, were carried out. Results of the investigation revealed otolarygological causes of the reported symptoms in 30 patients, whereas in 12 patients (out of 42 patients referred for prosthetic consultation), numerous functional disorders of the stomatognathic system were observed. The investigation confirmed the occurrence of functional disorders in patients with auriculo-vestibular symptoms and appropriateness of treatment by a multi-specialist team.
