[Screening for temporomandibular disorders : A sensible approach?]

Area of Science:

• Dentistry
• Oral Medicine
• Diagnostic Tools

Background:

• Temporomandibular disorders (TMDs) involve pain in jaw muscles and joints, and limited jaw movement.
• A German screening tool for TMDs was introduced in 2019, comprising patient history and clinical examination.
• The tool assesses jaw pain, mobility, muscle/joint palpation, jaw opening, occlusion, and joint noises.

Purpose of the Study:

• To determine the appropriateness of the nine components of the German TMD screening tool.
• To evaluate the general recommendation for screening individuals for TMDs.

Main Methods:

• Analysis of the components of the German Society of Craniomandibular Function and Disorders screening tool.
• Evaluation of the clinical relevance of patient history questions and specific clinical examination measures.

Main Results:

• Patient history questions and maximum jaw opening assessment effectively identify relevant TMD symptoms and signs.
• Four clinical measures within the screening tool were found to be inappropriate for TMD assessment.
• Screening for painful TMDs is deemed unnecessary as affected patients typically seek professional help.

Conclusions:

• The German TMD screening tool requires refinement, with specific components being ineffective.
• Widespread use of the current screening tool may lead to overdiagnosis and unnecessary interventions.
• Targeted assessment rather than broad screening may be more appropriate for managing TMDs.
