In PSR, Code 2 is primarily assigned for what reason?

• A. Calculus alone yields Code 2.
• B. Pocket depth determines Code 2.
• C. Mobility yields Code 2.
• D. Bleeding on probing yields Code 2.

Answer: (A)

In PSR, each sextant gets a code based on the most notable finding visible during screening. Code 2 is assigned when calculus or defective margins are present on any tooth within that sextant. The reason this is the trigger is that calculus acts as a persistent plaque-retentive factor and signals a need for professional cleaning and closer evaluation, even if probing depths aren’t very deep. Bleeding on probing reflects gingival inflammation and would place the sextant at Code 1, not Code 2. Mobility and deeper pocket depths point to more advanced situations and higher codes, but the presence of calculus is the primary factor that elevates a sextant to Code 2.
