Early Detection and Diagnostic Use:
Dental lasers, particularly CO2 lasers, are used for both diagnostic and therapeutic purposes in oral cancer cases. Advanced systems can combine imaging capabilities with biopsy functions, aiding early detection.
Patient Anxiety:
Laser biopsies typically cause less anxiety in patients compared to traditional scalpel methods, which is beneficial for sensitive procedures involving potential cancer.
Specific Advantages:
Minimal Bleeding: Highly beneficial in managing the vascular nature of oral tissues.
Reduced Risk of Seeding: Laser biopsies may lower the risk of cancer cell seeding along the biopsy tract.
Clear Surgical Margins: The precision of lasers helps in achieving clear margins, crucial for accurate diagnosis and treatment planning.
Staging:
Lasers can be utilized for staging procedures when oral cancer is confirmed, providing detailed information on the extent of the disease.
Challenges:
Thermal Damage: Proper settings are essential to prevent thermal artifacts that could affect histological examination.
Depth Control: Skilled operation is necessary to control the depth of the laser cut, especially in thin oral tissues.
Follow-Up:
Laser biopsies often lead to faster healing, allowing for quicker follow-up procedures if necessary.
Combination with Other Techniques:
Combining laser biopsy with techniques like fluorescence visualization can improve the accuracy of sample selection.
Research Applications:
CO2 lasers are being studied for their potential in photodynamic therapy for oral cancers, although this application is still largely experimental.
Training Requirements:
Proper training is crucial as the technique for laser biopsy differs from traditional methods, especially in tissue handling and margin control.
