Ace the FPC 2: 2026 PSR & Probing Practice – Smile Your Way to Success!

PSR screening relies on a specialized periodontal probe with marked increments. The marks let you quickly gauge pocket depths in each sextant and assign the PSR code based on how far the probe penetrates the sulcus. The ball tip helps minimize tissue trauma and allows smooth entry into the sulcus, while the color-coded bands indicate when readings cross predefined depth thresholds used for coding. A dental mirror aids visualization but doesn’t provide depth measurements, and scalers or curettes are used for cleaning, not screening.
