What indicates a need for further periodontal evaluation in patients?

• A. No bleeding upon probing
• B. Presence of Class I furcation involvement
• C. Increased PSR score
• D. All gum tissue being healthy

Answer: (C)

An increased Periodontal Screening and Recording (PSR) score indicates a need for further periodontal evaluation in patients because it reflects changes in periodontal health that necessitate a more detailed assessment. The PSR is a quick screening method that allows dental professionals to identify patients who may have periodontal disease. A higher score signifies greater severity or extent of periodontal issues, which may include probing depth, bleeding on probing, and the presence of calculus or dental biofilm. Therefore, an increased PSR score indicates that there may be underlying periodontal concerns that require more comprehensive examination and diagnosis.

In contrast, the presence of healthy gum tissue speaks to an absence of immediate periodontal issues, while Class I furcation involvement might not require further evaluation if there are no other indicators of periodontal problems. No bleeding upon probing is also a sign of healthy periodontal status, suggesting no immediate need for additional evaluation. Thus, the only option that clearly warrants an advanced periodontal review is the increased PSR score.
