Comparison of the multiphasic dysfunction profile with lateral transcranial radiographs

Area of Science:

• Dentistry
• Radiology
• Orthodontics

Background:

• Temporomandibular joint (TMJ) dysfunction encompasses a spectrum of signs and symptoms.
• Radiographic assessment is crucial for evaluating TMJ morphology and position.
• Understanding variations in TMJ parameters is essential for diagnosing associated dysfunction.

Purpose of the Study:

• To analyze condylar position, TMJ space, and condylar morphology using lateral transcranial radiographs.
• To investigate correlations between these radiographic findings and patient demographics (sex, age).
• To determine the relationship between radiographic TMJ changes and mandibular dysfunction scores.

Main Methods:

• Analysis of lateral transcranial radiographs from 926 patients.
• Evaluation of condylar position, TMJ space, and condylar morphologic characteristics.
• Statistical correlation of radiographic findings with sex, age, and mandibular dysfunction profile scores.

Main Results:

• Significant differences in condylar position and joint space were observed between males and females.
• Advancing age was associated with increased nonconcentric condylar position, joint space variations, and morphologic changes.
• A significant correlation was found between condylar position, joint space variations, condylar morphology, and mandibular dysfunction scores.

Conclusions:

• Lateral transcranial radiography is a valuable adjunct for diagnosing major TMJ changes.
• Radiographic TMJ parameters show significant variations related to sex, age, and mandibular dysfunction.
• These findings support the use of radiography in the comprehensive examination of patients with mandibular dysfunction.
