Long-term changes in biopsychosocial characteristics related to temporomandibular disorder: findings from the OPPERA study

Painful temporomandibular disorders (TMDs) are both consequence and cause of change in multiple clinical, psychosocial, and biological factors. Although longitudinal studies have identified antecedent biopsychosocial factors that increase risk of the TMD onset and persistence, little is known about long-term change in those factors after TMD develops or remits. During a 7.6-year median follow-up period, we measured change in psychosocial characteristics, pain sensitivity, cardiovascular indicators of autonomic function, and clinical jaw function among 189 participants whose baseline chronic TMD status either persisted or remitted and 505 initially TMD-free participants, 83 of whom developed TMD. Among initially TMD-free participants who developed TMD, symptoms and pain sensitivity increased, whereas psychological function worsened. By contrast, participants with chronic TMD at baseline tended to show improved TMD symptoms, improved jaw function, reduced somatic symptoms, and increased positive affect. In general, clinical and psychosocial variables more frequently changed in parallel with TMD status compared with pain sensitivity and autonomic measures. These findings demonstrate a complex pattern of considerable changes in biopsychosocial function associated with changes in TMD status. In particular, several biopsychosocial parameters improved among participants with chronic TMD despite pain persisting for years, suggesting considerable potential for ongoing coping and adapt...

Summary: Orofacial pain syndromes encompass several clinically defined and classified entities. The focus here is on the role of clinical neurophysiologic and psychophysical tests in the diagnosis, differential diagnosis, and pathophysiological mechanisms of definite trigeminal neuropathic pain and other chronic orofacial pain conditions (excluding headache and temporomandibular disorders). The International Classification of Headache Disorders 2018 classifies these facial pain disorders under the heading Painful cranial neuropathies and other facial pains. In addition to unambiguous painful posttraumatic or postherpetic...

Abstract Dental pain is the most common acute pain presenting in the orofacial region; however, chronic pain conditions are also frequent and include; temporomandibular joint disorders (TMDs), primary headaches (neurovascular pain), painful post-traumatic trigeminal neuropathy (PPTTN) and less commonly referred pain and idiopathic or centralized pain conditions. All of these conditions can mimic toothache and vice versa. Many of these conditions are comorbid with high levels of tension headache and migraine reported in patients with TMD; however, dentists remain unfamiliar with headaches and medics unfamiliar with...

Chronic pain in the orofacial region is common worldwide. Pain seems to affect the jaw motor control. Hence, temporomandibular disorders (TMD) are often accompanied by pain upon chewing, restricted mouth opening and impaired maximal bite forces. However, little is known on the effects of pain, in particular the effects of chronic jaw muscle pain on precision biting. The aim of the study was to investigate the effect of chronic and acute jaw muscle pain on oral motor control during precision biting in humans. Eighteen patients with chronic masseter muscle pain and 18 healthy participants completed the experiment. All partic...

Conclusion: This study demonstrates a higher OFP knowledge and confidence for dental specialists compared with GDPs. However, this difference does not necessarily translate into more competencies in clinical practice. Therefore, the implementation of OFP courses in dental schools' curricula may benefit future dentists and improve patients' care.

Pterygoid hamular bursitis is a rare craniofacial pain syndrome used to describe palatal and pharyngeal pain due to an enlarged pterygoid hamulus. The pterygoid hamulus is a hook-shaped bony process located bilaterally on each medial pterygoid plate of the sphenoid bone, posterior and medial to each maxillary tuberosity. These processes project downward and anterolaterally; serve as attachment for ligaments and a network of muscles. It can be palpated in patients with a finger palpating the posteromedial to maxillary tuberosity. The pathogenesis is elusive and varies from bursitis of tensor veli palatine, elongated pterygo...

This study aimed to determine differences in the tendon/muscle volume ratio of the temporalis muscle in patients with TMD myalgia compared with age-/gender-matched controls without facial pain.Study DesignThis was a retrospective, observational study of the temporalis muscle and tendon on MRI images. The comparison between groups was based on a voxel-based morphometry of anatomic T1-weighted MRI images and analyzed for differences in the tendon/muscle volume ratio. The study included at least 14 patients per group to detect a 5% difference in tendon/muscle volume ratio. An intraclass correlation coefficient was used to eva...

The diagnosis of temporomandibular disorders (TMDs), specifically TMD myalgia, can be challenging. Although the anatomy of the jaw muscles has been extensively characterized, a structural difference in TMD-myalgia individuals has never been demonstrated. Tendons are a highly specialized tissue with a predominately mechanical function. Collagen fibrils, the main contributor to tendon mechanical properties, begin macroscopic failure at 8% to 10% strain. The characterization of tendon/muscle abnormalities in individuals with chronic, painful TMD myalgia will lay the groundwork for utilizing noninvasive magnetic resonance imag...

Painful temporomandibular disorders are chronic conditions that can have a negative impact on the quality of life and well-being of affected individuals. It is frequently associated with dysfunction of the masticatory muscles due to specific or non-specific temporomandibular disorders. Potential risk factors for painful temporomandibular disorders include trauma, dental malocclusion, excessive masticatory system loading, hypermobility, parafunctional habits and anatomical, psychosocial and/or systemic disorders.
