Aims
Evaluate clinical suitability of dental materials based on radiodensity and distortion.
Background
Image distortion impacts dosimetric accuracy during radiotherapy for head and neck cancer patients.
Methods
Evaluated 6 material types using CT scan; analyzed radiodensity (HU values) and distortion.
Results
Identified 5 materials with HU values similar to human tissues; 3 showed significant distortion.
Conclusion
Recommend testing on actual-size samples for clinical use.
Lessons Learnt
Dimensional stability and fabrication time are critical factors for future evaluations.
