What is the critical probing depth for periodontal surgery according to Lindhe et al (1982)?

• A. 2.9 mm
• B. 3 mm
• C. 4.2 mm
• D. 5 mm

Answer: (D)

The concept of critical probing depth in the context of periodontal surgery refers to a threshold depth at which the likelihood of achieving successful surgical outcomes diminishes and where the presence of periodontal disease becomes more significant. According to Lindhe et al. (1982), the critical probing depth is identified as 5 mm. This finding underscores the importance of this measurement in clinical practice, as it helps clinicians determine which sites may benefit most from surgical intervention. Probing depths greater than this threshold typically indicate more severe periodontitis, which can lead to greater challenges in managing the disease effectively through nonsurgical means alone. Thus, understanding the significance of this critical probing depth aids dental professionals in making appropriate treatment decisions and setting realistic expectations for periodontal therapy's effectiveness.
