Happy Pi Day! 3..14.21 – 𝛑 🍰 PI for Dentist means something entirely different than something used in math or a delicious dessert you eat after Thanksgiving dinner. In Dental Medicine, The Plaque Index (PI) is a scoring system, developed by Silness and Loe, (1963) used to record the thickness of the plaque and the proportion of each tooth covered by it.

A zero indicates no plaque present; 1 indicates a film of plaque present on the tooth; 2 represents moderate accumulation of soft deposits in the gingival pocket or on the tooth that can be seen by the naked eye; 3 represents an abundance of soft matter within the pocket or on the tooth. 🦷🪥✨
