Instruments and Processes
Diagnostic Devices and Techniques
Swept Source Optical Coherence Tomography (SS-OCT)
Advantages
High Resolution Cross Sectional Images (Microstructures in Biological Systems)
Detects structural flaws and variations at submicron scale
Mechanism
Infrared Laser Optics
Use
Monitor Accuracy of Composite Restoration
Detection of Occlusal Caries
Laser-induced Fluorescence
Advantage
Aids Direct Visual Assesment and Comparison
Use
Detect and Quantify Mineralization and Caries Activity
Mechanism
Teeth illumination with high intensity Blue Light
Green Light Emitted implying less Mineral Content
Laser Photothermal Radiometry (PTR)
Mechanism
Detects Black Body radiations from hard dental tissue
Increase light scatter and absorption by Caries
Increased thermal wave amplitude showing contrast between caries ad intact enamel
Ultrasound Imaging
Advantages
High Resolution Images
Specificity and Sensitivity
Non-Ionizing and Non-Invasive
Uses
Detection of Demineralization
Detection of Cracks and Calculus
Infrared Spectroscopy for Multiple Inflammatory Parameters
Mechanism
Measure haemodynamic tissue changes in Periodontal region
Uses
Detect Peri-Implant Inflammation
