Abstract
In this paper, the concept of temporomandibular disorders (TMD) was outlined. TMD is a collective term embracing all the problems relating to the temporomandibular joint and related musculoskeletal structures. The patients who have masticatory muscle and/or joint pain, joint noise, or problems in jaw movement without well-known etiology are exclusively diagnosed as TMD. Therefore, TMD contains multifactorial nature of conditions, including masticatory muscle pain disorders, joint pain disorders, disc derangement, and osteoarthritis/osteoarthrosis.
