What each input means

Average Pocket Depth (mm): Mean probing depth across all measured sites
Sites ≥4mm: Number of sites with probing depth of 4mm or greater
Sites ≥6mm: Number of sites with probing depth of 6mm or greater
Bleeding Sites: Number of sites with bleeding on probing
Total Sites Measured: Total number of probing sites (typically 6 per tooth × 28 teeth = 168)
