Lafrenière and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 1995 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intramuscular EMG of the lateral pterygoid muscles, surface EMG of the temporalis and masseter muscles, electrogoniometry and force measurements of the TMJ were synchronously used to investigate the biomechanical role of the two portions of the lateral pterygoid muscle in relation to internal derangement (ID) of the temporomandibular joint (TMJ). This study dealt with the EMG analysis of five static conditions: resting, resisted protraction, maximum voluntary contraction (MVC) in opening, in molar and incisor clenching of TMJ ID and control subjects. The analysis of variance results of the integrated linear envelop (LE) EMG showed no significant differences between the two groups. The integrated LE EMG of the SLP was significantly lower in the TMJ group during molar clenching (104$\mu$V $\pm$ 60.0 over 159$\mu$V $\pm$ 68.8 for a p =.020). The SLP seemed to have lost its discal stabilizing function during clenching. The integrated LE EMG signals of the ILP were significantly higher in the TMJ ID group during rest, resisted protraction and incisor clenching (p =.029, p =.046, p =.031 respectively). The ILP muscle has probably adapted to control the inner joint instability while continuing its own actions. The results of the isometric forces showed that TMJ ID subjects exhibited significantly lower molar bite forces (297.1N over 419N, p =.042) confirming that they have less muscle strength and tissue tolerance than subjects with healthy masticatory muscle system. Incisor bite forces, however, showed a tendency to be higher in the TMJ ID group (233N over 180.5N, p =.168), possibly resulting from the training of a protracted bite and/or hyperactivity of the ILP associated with ID. Therefore a neuromuscular adaptation could be occurring in TMJ ID masticatory system affecting muscular actions and forces. (Abstract shortened by UMI.).

Download or read book Contemporary Management of Temporomandibular Disorders written by S. Thaddeus Connelly and published by Springer. This book was released on 2019-03-30 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive, state of the art guide to the contemporary diagnosis of temporomandibular disorders (TMDs) that will help to compensate for the frequent lack of experience and inadequate training among health professionals who encounter patients with jaw joint problems. The opening section describes the whole patient philosophy essential for treatment success, examines ethical and legal considerations, and discusses all aspects of anatomy. Pathophysiology, clinical assessment, and imaging evaluation, including by means of modern MR imaging and CBCT, are then considered in detail. Finally, the diagnostic criteria for the full range of TMDs are thoroughly explained and the urgent need to appreciate temporomandibular disorders as the chronic pain conditions they are is addressed. Complementary volumes are devoted to non-surgical treatment of TMDs and to total temporomandibular joint replacement and other surgical procedures, respectively. Each book will be of high value for the multidisciplinary team necessary for successful management of TMDs, including dentists, surgeons, primary care doctors, pain doctors, and allied health professionals.

This book was released on 2015-07-22 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews and discusses some of these approaches, and some of the controversies aroused by them in the hope that the dental profession will soon arrive at more effective, scientifically based treatments. Health professionals have dealt with temporomandibular disorders, a major cause of non-dental pain in the orofacial region, by developing a broad range of treatments, ranging from occlusal alteration to multidisciplinary care regimens. It is with this background that health practitioners have responded to their patients' needs by developing a broad range of treatments, often determined more by the specialty of the practitioner than by scientifically-based treatment. There are practitioners claiming successful outcomes from a diverse number of treatments ranging from education and behavioral counseling, use of medications, occlusal therapies, surgery and splints, to a combination of various treatments.

This book was released on 2020-07-01 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Temporomandibular disorders (TMDs), are a set of more than 30 health disorders associated with both the temporomandibular joints and the muscles and tissues of the jaw. TMDs have a range of causes and often co-occur with a number of overlapping medical conditions, including headaches, fibromyalgia, back pain and irritable bowel syndrome. TMDs can be transient or long-lasting and may be associated with problems that range from an occasional click of the jaw to severe chronic pain involving the entire orofacial region. Everyday activities, including eating and talking, are often difficult for people with TMDs, and many of them suffer with severe chronic pain due to this condition. Common social activities that most people take for granted, such as smiling, laughing, and kissing, can become unbearable. This dysfunction and pain, and its associated suffering, take a terrible toll on affected individuals, their families, and their friends. Individuals with TMDs often feel stigmatized and invalidated in their experiences by their family, friends, and, often, the health care community. Misjudgments and a failure to understand the nature and depths of TMDs can have severe consequences - more pain and more suffering - for individuals, their families and our society. Temporomandibular Disorders: Priorities for Research and Care calls on a number of stakeholders - across medicine, dentistry, and other fields - to improve the health and well-being of individuals with a TMD. This report addresses the current state of knowledge regarding TMD research, education and training, safety and efficacy of clinical treatments of TMDs, and burden and costs associated with TMDs. The recommendations of Temporomandibular Disorders focus on the actions that many organizations and agencies should take to improve TMD research and care and improve the overall health and well-being of individuals with a TMD.

This book was released on 1992 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: This proceedings volume discloses the various and, at times, conflicting views regarding temporomandibular disorders (TMD) as presented at the Craniomandibular Institute's 10th Annual Squaw Valley Winter Seminar held in January 1991. The field of TMD has been long on testimonials and clinical opinion but short on scientific documentation. As a result, there is presently a growing concern in the field that scientific foundation is needed to support the various belief systems and to improve credibility. This seminar encouraged participants to openly discuss and expose the controversial issues plaguing the field and to provide clinical and basic research to support or to question those issues. To this end, 14 internationally renowned experts assembled to discuss the current status of terminology, epidemiology, etiology, diagnoses, and management for TMD. This book is divided into four main parts, each of which helps to provide the reader with a better understanding of the complexity of TMD. A wide variety of scientific evidence, clinical experience, and informed opinions is presented. This variety will ensure that the volume will serve as the foundation for future discoveries in the study of TMD. As such, this book will be of interest to all who work within the field.

Available in PDF, EPUB and Kindle. Book excerpt: The underlying nociceptive mechanisms in temporomandibular joint (TMJ) and masticatory muscles in many pain conditions are still unclear, largely due to the limited study of peripheral and central neural mechanisms affecting craniofacial musculoskeletal tissues. This study provided evidence in support of Hypothesis 1: Peripheral glutamatergic and capsaicin-sensitive mechanisms modulate the properties of primary afferents and brainstem neurons processing deep craniofacial nociceptive information. Effects of glutamate and capsaicin injected into the receptive field of deep craniofacial nociceptive afferents or TMJ of TMJ-responsive nociceptive neurons in trigeminal subnucleus caudalis/upper cervical cord (Vc/UCC) were studied in halothane-anesthetized rats. When injected alone, glutamate and capsaicin activated and induced peripheral sensitization in many afferents. Following glutamate injection, capsaicin-evoked activity was greater than that evoked by capsaicin alone, whereas following capsaicin injection, glutamate-evoked responses were similar to those of glutamate alone. When injected alone, glutamate and capsaicin also activated and induced central sensitization in most Vc/UCC neurons. Following glutamate injection, capsaicin evoked greater activity and less sensitization compared with capsaicin alone, whereas following capsaicin, glutamate was less effective in activating and sensitizing most Vc/UCC neurons. This apparent desensitizing effect of capsaicin on glutamate-evoked excitability of Vc/UCC neurons contrasts with the lack of capsaicin-induced modulation of glutamate-evoked afferent excitability, suggesting that peripheral and central sensitization may be differentially involved in the nociceptive effects of glutamate and capsaicin applied to deep craniofacial tissues. Further evidence of glutamate-capsaicin interactions was documented in the attenuation by TMJ pre-injection of glutamate receptor antagonists of jaw muscle activity reflexly evoked by TMJ injection of capsaicin. Moreover, additional findings support Hypothesis 2: Surgical cutaneous incision modulates the properties of brainstem neurons processing deep craniofacial nociceptive information. TMJ-responsive nociceptive Vc/UCC neurons could be activated by surgical incision of the skin overlying the TMJ and this incision-induced afferent barrage caused nociceptive neurons to be temporarily refractory to further capsaicin-induced central sensitization.These novel findings suggest that peripheral glutamate and capsaicin receptor mechanisms as well as surgical cutaneous incision may be involved in the nociceptive processing of deep craniofacial afferent inputs and may interact to modulate both activation as well as sensitization evoked from these tissues.
