Study Summary

Temporomandibular disorder (TMD) is a term describing musculoskeletal conditions of the face, jaw and temporal regions. TMD is frequently associated with pain and/or dysfunction such as impaired jaw function, pain in the temporomandibular joint (TMJ), muscles and/or related structures, and associated headaches. The aetiology of TMD is multifactorial and complex.

Study Description

It is known that one cause of TMD symptom development is treatment for head and neck cancer (HNC). The main treatment modalities for HNC include radiotherapy (RT) with or without chemotherapy and surgical intervention, either as a single therapy or a combination therapy. In the head and neck region, the anatomical structures are necessary for essential functions such as speech, swallowing, breathing, smell, and taste. The treatment of head and neck tumours may frequently impair some of these functions, which may result in pain, oral dysfunction, and impaired health-related quality of life.

High intensity laser therapy (HILT) is a non-invasive and painless treatment method. The latest studies have reported the beneficial effects of neodymium-doped yttrium aluminum garnet (Nd: YAG) laser therapy in patients with pain. The advantage of HILT over low level laser therapy (LLLT) is that HILT is able to penetrate and stimulate wider and/or deeper areas; thus, considerably more energy may be transmitted to tissue during HILT therapy compared to LLLT.
