Active clinical trials for "Temporomandibular Joint Disorders"

This study is a 2-arm parallel, assessor blinded, multi-centre, randomised controlled trial.

Stroke affects the vital activities of daily living such as breathing and swallowing. After stroke excursion of the diaphragm reduces about 50%, and also the maximum expiratory pressure of the individual 50% or higher. Dysphagia occurs in 29% to 45% of the acute stroke cases.

Temporomandibular joint (TMJ) discectomy is one of the most popular surgical techniques for painful TMJ. Previous studies have demonstrated predictable results of discectomy with optimal results in pain reduction and maximum mouth opening (MMO) improvement. However, those studies had most of the times varied inclusion criteria. A 4-year prospective study was designed including patients treated with unilateral TMJ discectomy without interposal material as the first surgical procedure for two specific intra-articular diagnosis: disc perforation and disc fragmentation.

Introduction: Although there are physiotherapy programs that are widely used in the treatment of Temporomandibular Disorders (TMD), there are few studies investigating the effects of home exercises program specifically developed for TMD. Aim: Investigators aimed to investigate the effect of home exercise program on pain and quality of life in TMD treatment. Methods: 20 patients were included in our pilot study and were randomised into two groups. Home exercises program and physiotherapy program were applied to the intervention group (n=10; age 31.4±11.2 years), and only physiotherapy program to the control group (n=10, age 35.3±18.1 years). Physiotherapy program included ultrasound (US), Transcutaneous Electrical Nerve Stimulation (TENS) and exercise. Investigators measured pain with the Visual Analogue Scale (VAS) and quality of life with the Short Form 36 (SF-36) before and after the treatment.

Physical therapy is one of the initial conservative treatments for TMD. Many studies and previous studies in our department have proved that it can improve the pain, mouth opening and mandibular function of patients with TMD. However, the current research on physical therapy for TMD has a short follow-up period, which cannot prove that the patients' long-term mandibular function has improved, and few studies have analyzed the relevant factors affecting the curative effect. Therefore, this study is intended to adopt a retrospective cohort study to include TMD patients who received physical therapy in our department from 2016.01-2021.12. The patients' pain, joint area noise, mandibular range of motion, mandibular function and other conditions will be followed up by remote telephone or online questionnaire, and the patients' demography, clinical symptoms, pain, oral habits, depression, anxiety, sleep status, head and neck posture and other information will be collected. The multiple regression analysis model will be used to compare and analyze the relevant factors affecting the prognosis of patients, and to intervene in advance the factors that have a significant impact on the prognosis of the disease, so as to improve the treatment effect.

The goal of this prospective cohort study is to evaluate the effectiveness of combined arthrocentesis and occlusal stabilization splint therapy in patients diagnosed with disc displacement without reduction of temporomandibular joint-induced closed locks. The main questions it aims to answer are: Is there a difference in the treatment response between chronic and acute closed-lock conditions? On which dimensions of pain did the treatment have positive effects? Participants will be preoperatively examined and assigned to one of the two study groups. All participants undergo a single session of TMJ arthrocentesis. Following the arthrocentesis session, all participants will use preoperatively fabricated occlusal splints. Participants will be recalled in one week to evaluate the outcomes. Researchers will compare acute and chronic closed-lock groups to see if there are differences between pain intensities and mouth-opening amounts postoperatively.

The term temporomandibular joint disorder (TMD) refers to a group of disorders affecting the temporomandibular joint and/or muscles of mastication. Typical symptoms are; joint noises, pain, and limited mouth opening. Many therapeutic modalities have been advocated for the treatment of TMD as intraoral splints, laser, ultrasound, physical therapy, surgery, and medications with inconsistent reported results due to the multifactorial etiology of this disorder. Although intraoral splints are the most widely used therapy, it has some drawbacks as being inconvenient for the patient due to their relatively large size interferes with eating and affects speech, therefore their use is mostly limited to sleeping time, which decreases its effectiveness. Recently some commercial earplugs that claim to treat TMD have been introduced, however, there is no validated data regarding these appliances. Thus, this study aimss to evaluate the possible effect of earplugs on myogenous TMD.

The Low Level Laser Therapy (LLLT) has been recently introduced with success in the management of the pain associated to this condition. This double blind placebo controlled clinical trial analyzes a new home LLLT protocol to verify whether it was possible to avoid to the repeated presence at dental chair required by traditional LLLT protocols.

Purpose: Primary: To evaluate the efficacy of extended-release (ER) propranolol compared to placebo in the reduction of a pain index in patients with temporomandibular disorder (TMD). Secondary: To determine if extended-release propranolol efficacy varies according to participants' catechol-O-methyltransferase (COMT) genetic polymorphisms and to investigate the efficacy of extended-release propranolol compared with placebo using secondary endpoints. Exploratory: To investigate whether the efficacy of extended-release propranolol in the reduction of the pain index varies according to participants' polymorphisms in 3 other genetic regions and according to various phenotypic characteristics. Participants: 200 patients with chronic TMD will be randomly assigned, in a 1:1 parallel, double-blind fashion, to receive either extended-release propranolol or placebo at one of three study sites: University of North Carolina-Chapel Hill School of Dentistry; University of Florida-Gainesville College of Dentistry; and the State University of New York at Buffalo School of Dental Medicine. Procedures (methods): Randomization will be to either propranolol or placebo. The 10-week study treatment period is divided into: 1 week of drug titration, 8 weeks of drug maintenance, and 1 week of drug tapering. The titration and tapering doses are 60 mg (capsules) once per day orally; the maintenance dose is 60 mg twice per day orally. Participants will attend 6 clinic visits over 12-15 weeks as follows: screening and baseline visit (Visit [V] 0, 7-21 days prior to V1); randomization and start of treatment (titration) (V1, study day 0); maintenance visit 2 (V2, 1 week post-randomization, study day 7+3); maintenance visit 3 (V3, 5 weeks post-randomization, study day 35 +/- 7); tapering visit (V4, 9 weeks post-randomization, study day 63 +/- 7); and tapering visit 5 (V5, 11 weeks post-randomization and 1 week after drug tapering ends, study day 77 +/- 7). Depending on the visit, procedures will include: reviews of medical history, weekly alcohol consumption, concomitant therapies and medications, adverse events, compliance, and eligibility; administration/review of questionnaires; blood draw; pregnancy test in women of childbearing potential; and dispensing of study drug.

The purpose of this study was to compare the effectiveness of soft occlusal splint therapy on the electromyographic activity of masticatory muscles (ateriors temporalis and masseter) before and after the application of a muscle relaxation splint. Electromyography recordings from the masseter and anterior temporalis muscles were analyzed quantitatively during maximal clench, rest and mastication usual, before and after the treatment without a splint. Ten patients whose chief complaint was Temporomandibular Disorders (TMD) were selected for the study. After the initial evaluations soft occlusal splints (muscle relaxation splints) were applied, and the patients were instructed to use the splints for four weeks. Surface electromyographic recordings were taken from each patient, as clinical evaluations of TMD (Index of Helkimo), both evaluations before the beginning of clinical therapy and after four weeks of wearing splints. The data obtained were analyzed by Wilcoxon´s and Friedman´s tests.
