🦷 Community Periodontal Index (CPI) Simulator

Dividing the Dentition Into Six Probing Sextants

CPI splits the mouth into six sextants for systematic screening.

• 6: Sextants examined (placeholder metric)
• up to 2: Index teeth per sextant (placeholder metric)
• ~20g: Probe force (placeholder metric)
• ~5 min: Screening time (placeholder metric)

Sextant probing overview

Placeholder: probe moves systematically around each sextant.

Detecting Gingival Bleeding as an Inflammation Signal

Bleeding after probing flags active gingival inflammation.

• CPI 1: Bleeding code (placeholder metric)
• 10-30s: Wait time (placeholder metric)
• moderate: Sensitivity (placeholder metric)
• plaque: Common cause (placeholder metric)

Bleeding detection overview

Placeholder: bleeding droplets appear at the gumline when present.

Feeling for Subgingival Calculus With the Probe Tip

Rough calculus deposits are detected by tactile probing.

• CPI 2: Calculus code (placeholder metric)
• tactile: Detection method (placeholder metric)
• lingual incisors: Common site (placeholder metric)
• mineralized plaque: Composition (placeholder metric)

Calculus detection overview

Placeholder: yellow deposits render along the tooth-gum junction.

Reading Millimeter Markings for Pocket Depth

Probe markings at 3.5, 5.5, and 8.5mm define shallow to deep pockets.

• <4mm: Shallow pocket (placeholder metric)
• 4-5mm: Moderate pocket (placeholder metric)
• 6mm+: Deep pocket (placeholder metric)
• 3: Marking bands (placeholder metric)

Pocket depth overview

Placeholder: probe inserted into the pocket shows a live depth reading.

Assigning the Worst Finding as the Sextant Score

Each sextant is scored by its single worst finding, codes 0 to 4.

• 0-4: Code range (placeholder metric)
• worst wins: Rule (placeholder metric)
• X (missing): Excluding code (placeholder metric)
• 6 sextant scores: Output (placeholder metric)

Final scoring overview

Placeholder: all six sextants light up with their final CPI code.

Placeholder: the highest sextant code guides referral for periodontal treatment.
