Previously known as: International RDC/TMD Consortium Network

May 27, 2017. A change in the name of The International RDC/TMD Consortium Network was overwhelmingly approved by the Consortium membership, and the name change was formally approved by IADR Council. The organization remains a consortium fostering the evidence-based diagnosis and management of orofacial pain and jaw disorders.

Feb 1, 2020. The INfORM website will  not migrate to the IADR webserver. Instead, two websites will be maintained: the IADR-based website for INfORM will serve organizational needs as part of IADR, while this website will maintain materials pertaining to INfORM activities. Meanwhile, this website remains incomplete compared to its prior version from 2000 through February 2017. If you have reached this page while trying to link to a particular page or document, your linking-URL will currently not work. Our apologies. We encourage you to check back for updates.
Our goal is to advance the scientific knowledge of temporomandibular disorders (TMD), orofacial pain, and jaw disorders through scientifically developed diagnostic tools based on standardized assessment.  These tools are intended to be applicable to both research and clinical settings, including international use, multi-site and cross-cultural research studies. We review progress at our  annual meetings and international consensus workshops. Please contact us if you are interested in participating in our activities; our past meetings will give you an idea of what we do. The core tool that established the Consortium, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD), remains a model for pain research. That tool is now replaced by the DC/TMD (2014) for both clinical and research use.  The next wave of research regarding TMDs and how they are conceptualized will be conducted using the DC/TMD as well as other research tools that will be posted on this site.  Our methods include population studies, clinical epidemiology and clinical trials, and experimental human studies.


Developing Evidence-based Management Guidelines for Temporomandibular Disorders (9/25/2020). An INfORM-sponsored symposium previously planned for IADR/March2020 will be held via Zoom on Nov 18, 2020. Details are here.

INfORM Young Investigator Awards, sponsored by Quintessence Publishing and Journal of Oral & Facial Pain and Headache (10/12/2020).

The next competition was scheduled for March 2020 (Washington DC) but the full meeting was cancelled. A virtual competition will be held instead as replacement, and a new competition will be held at the 2021 meeting.

DC/TMD Examiner Training Courses (2/16/2020).  There are currently no scheduled training courses. Click for further information regarding the most recent course.

Consortium activities at IADR-London (10/12/2020). Two invitational workshops focused on development of a brief DC/TMD for routine clinical use, and a DC/TMD adapted for children and adolescents. The latter project is now completed and under review at a journal.

Consortium activities at IADR-Seoul, Republic of South Korea (3/15/2016; updated 10/12/2020). The manuscripts from all three workshops have now been published regarding Axis II implementation in international settings.

DC/TMD examination videos (3/15/2016). The English language version was released in 2014 and published via MedEdPORTAL.  That version has now been accompanied by a Swedish language version, to be released soon on the website. Others are encouraged to develop other language versions or to consider how the English language version can be modified with menu-selected sub-titles.  See the DC/TMD page for further information.

An Executive Summary of the DC/TMD was published (3/15/2016). This publication was developed for the target audience of the general dentist.  It is available at JADA.
