Temporomandibular dysfunctions/disorders (TMDs) comprises of a complex and heterogeneous group of conditions which includes Temporomandibular joint (TMJ), soft tissue structures within the joint and the muscles of mastication. TMDs are also referred to as craniomandibular disorder.
It is seen that about 75% of adult population have at least one symptom associated with TMDs, and 30% have more than one symptom while 3-7% apply for treatment. There is estimation that 20-25% of the population is affected with TMDs, with female to male ratio being 3:1 to 6:1. It is more prevalent between the age group of 20-40 years. Epidemiological studies have also shown that TMDs are most common in younger females of 18-45 years, which is during their reproductive age.
