'Temporomandibular disorders' is an umbrella term for disorders of the temporomandibular joints, the masticatory muscles, and the adjacent anatomical structures. On behalf of the International Network for Orofacial Pain and Related Disorders Methodology, this article gives an overview of key points for good clinical practice in the field of temporomandibular disorders. During an annual conference in March 2024, members of the aforementioned network drew up a list of 10 core principles. These core principles include knowledge about the causes, diagnosis and treatment of temporomandibular disorders. They summarize the current standard of care for the treatment of such conditions and are in keeping with the need to help increase the expertise of dentists working in general practice and to prevent incorrect treatment. The core principles can be regarded as a starting point for other national and international organisations to use to develop guidelines and recommendations for the treatment of temporomandibular disorders.
