FPC 2 Exam 2026 – Master Periodontal Screening and Recording (PSR) with the Complete Probing Practice Test!

Optimal probing relies on positioning that lets you reach all surfaces comfortably and accurately. Sitting upright or in a slight semi-supine position gives good access to posterior sextants while keeping the jaw muscles relaxed. This setup makes it easier to insert the probe at the correct sulcular angulation and depth without patient movement or muscle tension distorting the readings. A fully prone or flat position with restricted jaw access hinders access to back teeth, can increase muscle tension or gag reflex, and tends to produce unreliable measurements.
