DIAGNOdent: Infrared Diode Laser (650 nm), Score Range 0-99

Technology Specifications:

• Wavelength: 650 nm (red diode laser)
• Score range: 0-99 numerical scale
• Detection method: Fluorescence measurement
• Manufacturer: KaVo (Germany)

Working Principle:

1. Laser emission: 650 nm infrared light
2. Tissue interaction: Excites bacterial porphyrins
3. Fluorescence detection: Measures emitted light
4. Quantification: Converts to numerical score (0-99)

Score Interpretation:

• 0-13: Healthy tooth structure
• 14-20: Initial demineralization
• 21-29: Established caries in dentin
• 30-99: Advanced caries progression

Clinical Applications:

1. Occlusal caries detection
2. Smooth surface caries
3. Secondary caries assessment
4. Treatment monitoring
5. Preventive program evaluation

Advantages:

✅ Non-invasive and painless ✅ Quantitative assessment ✅ Early caries detection ✅ Real-time results ✅ Patient education tool

Limitations:

❌ False positives: Stains, plaque, calculus ❌ Operator technique dependent ❌ Cannot differentiate caries depth ❌ Not suitable for approximal surfaces

 EXAM PEARL: DIAGNOdent uses 650 nm wavelength and provides scores from 0-99 for caries detection.
