International Symposium on Temporomandibular Joint Disorders and Chronic Orofacial Pain

Orofacial pain associated with osteoarthritis (OA) in the temporomandibular joint (TMJ) is a significant clinical problem [1]. The pathophysiologic and cellular mediators that underlie the development of such chronic orofacial pain are not well understood, nor has a relationship to mechanical loading been defined. Several experimental models have been developed to examine causative factors in TMJ OA progression and joint pathology. Such models often involve intra-articular injections or surgical manipulation of tissue structures in order to alter joint kinematics and stability [2–6]. For example, severing of the discal attachments followed by anterior displacement of the disc has been employed in a rabbit model, while disc perforation and scraping of the condylar surface have been used in sheep models to induce OA symptoms [2,3]. A limitation of the above approaches is that they introduce artificial damage to the joint structures and do not approximate the clinical disorder of mechanically-induced TMJ OA. Therefore, the goal of this pilot study was to develop a novel model of TMJ OA via non-invasive and mechanically relevant methods that could produce behavioral hypersensitivity (mechanical allodynia) suggestive of pain symptoms and histological changes in the TMJ consistent with osteoarthritic pathology.

Abstract Objective The aim of this study is to improve the safety and efficiency of prosthodontic treatment of patients with dental defects. It is necessary to perform a comprehensive assessment of the dentofacial system disorders, including the analysis of the features of pain manifestations. This study also supports to improve the efficiency of prosthodontic rehabilitation of patients with complete dental reconstruction on the basis of an assessment of the severity of orofacial pain manifestations. Materials and Methods The study was a single-site prospective open nonrandomized study with the examination and treatment of 452 patients (age = 44.3 ± 15.2 years, including 282 men and 170 women) with partial or total edentulism. The patients were divided into two groups: group 1 (control) of 218 patients treated with a standard prosthodontic approach and group 2 (study) of 234 patients treated which the proposed interdisciplinary approach to prosthodontic rehabilitation. Results The study establishes higher safety and clinical efficiency of the proposed interdisciplinary approach. The patients undergoing full-mouth reconstruction with the use of the interdisciplinary approach demonstrated statistically significant decrease in the rate of pain in muscles of the maxillofacial area on palpation, pain, and spasms in the neck area, statistically significantly less frequent pains in the temporomandibular joint (TMJ) during chewing, pain during opening and closing the mouth. Conclusion The application of the developed comprehensive approach to prosthodontic rehabilitation planning makes it possible to improve essentially the results of treatment at the expense of reduction of pain manifestations in the area of maxillofacial muscles and pain sensations associated with functioning of the TMJ.

Background: Temporomandibular disorders have been considered as a common orofacial pain condition. The term temporomandibular pain dysfunction (TMPD) is used synonymously with myofacial pain dysfunction disorder/syndrome, temporomandibular disorder, craniomandibular disorder and many other terms. Objective: To evaluate the prevalence of signs and symptoms of temporo-mandibular joint disorder (TMD). Study Design: Descriptive cross-sectional study Place and Duration of Study: Department of Oral and Maxillofacial Surgery, Faryal Dental College, Sheikhupura , Lahore, Pakistan from 1st February 2019 to 31st May 2021. Methodology: One hundred adolescents aged 15 to 60 years were enrolled. A detailed history about the chief complaint was taken and clinical examination was done. Temporomandibular joint examination performed included Auscultation for temporomandibular joint sounds like clicking and crepitus and palpation of both TMJs and associated muscles for evaluation of pain. Results: The most common signs of temporomandibular joint disorders were temporomandibular joint pain 78%, temporomandibular joint clicking 53% and trismus 29%. The most prevalent predisposing factors of temporomandibular joint disorders were parafunctional habits 40%, unknown factors 23% and history of road traffic accident/history of difficult extractions 9%. Male to female ratio showed female predominance (P = 0.001). Conclusion: Signs and symptoms of temporomandibular joint disorders were prevalent in Pakistani population with a clear female predominance.
