Temporomandibular disorders (TMD) are a group of symptoms related to impaired function of the temporomandibular joints (TMJs) and associated muscles. The symptoms can include pain or tenderness of TMJs area, clicking or grating sounds in the TMJs, limited jaw movements, myofascial pain, headache, tinnitus, impaired hearing, earache, and pain about the tongue. Great significance in development of the TMD is psychological, occlusal, and general health factors. Multifactorial pathogenesis of this syndrome determines the need for interdisciplinary treatment. Oral parafunctions may include teeth grinding, biting the cheek and lip, nail biting, or pen chewing. These unnecessary functions are closely related to TMD and often require a common treatment.

We invite investigators to submit original research and review articles that seek to define the epidemiology, detailed pathogenesis, accurate diagnostics, and interdisciplinary therapeutic possibilities of TMD and oral parafunctions. We are interested in articles that explore these aspects.

Potential topics include, but are not limited to:

• Epidemiology of TMD and oral parafunctions
• Psychological aspects of TMD and oral parafunctions pathogenesis
• Systemic diseases that affect the development of TMD
• Occlusal trauma
• Imaging of the TMJs pathologies and movements
• All aspects of myofascial pain treatment
• Physiotherapy, pharmacotherapy, and natural therapy in TMD management
• Psychotherapy aspects in oral parafunctions treatment
• Treatment of ear symptoms related to TMD
• Occlusal splint therapy
• New concepts and materials in occlusal rehabilitation
• Surgical therapy of TMJs degeneration
