Which statement describes PSR Code 3 criteria?

• A. Bleeding May Be Present
• B. Calculus May Be Present
• C. PD Between 3.5 And 5.5 mm
• D. All Of The Above

Answer: (D)

PSR uses a quick screening approach with a probe marked at 3.5 and 5.5 mm. The code assigned to a sextant reflects the most advanced finding observed there, signaling how thoroughly the patient needs to be evaluated. A Code 3 sextant indicates more than trivial periodontal involvement and prompts a full periodontal assessment.

Bleeding on probing shows gingival inflammation, which is a sign of periodontal activity. Calculus presence can contribute to plaque retention and disease progression. Probing depths in the range of 3.5 to 5.5 mm indicate pockets that are deeper than mild but not yet severe. When these kinds of findings appear, they support assigning a Code 3 classification, reflecting a need for closer evaluation and possible referral.

Thus, each of these observations can be part of the criteria that lead to Code 3, making the statement that all of the above describe Code 3 criteria the best choice.
