Using the Trismus Checklist to identify potential malignancy

Area of Science:

• Dentistry
• Oral Medicine
• Diagnostic Tools

Background:

• Trismus, or jaw stiffness, is frequently encountered in primary dental care.
• Causes range from temporomandibular disorders to rare but critical malignancies.
• Accurate diagnosis is essential for timely intervention.

Purpose of the Study:

• To introduce the Trismus Checklist, a nine-item screening tool.
• To standardize the diagnostic process for patients presenting with trismus.
• To improve patient safety by identifying significant underlying pathology.

Main Methods:

• Implementation of the Trismus Checklist for structured diagnosis.
• Objective measurement techniques, including intra-incisal distance recording (accounting for bite variations).
• Utilizing a passive stretch test to differentiate myogenic limitations from mechanical obstructions.

Main Results:

• The Trismus Checklist provides a systematic approach to trismus diagnosis.
• Objective measurements and specific tests aid in differentiating causes.
• Routine use helps prevent missed diagnoses of serious conditions.

Conclusions:

• The Trismus Checklist enhances clinician confidence and patient safety.
• Objective monitoring and follow-up are crucial for all trismus cases.
• Early and accurate diagnosis, facilitated by the checklist, is paramount.
