What preparatory step is necessary regarding diabetic patients before periodontal surgery?

Before periodontal surgery, it is essential for diabetic patients to have their blood glucose levels well controlled. This step is critical because poorly controlled diabetes can significantly affect healing and increase the risk of postoperative complications, such as infections. Elevated blood sugar levels lead to impaired immune responses and can exacerbate periodontal disease. By ensuring that a diabetic patient's glucose levels are within an acceptable range prior to surgery, the clinician can improve outcomes and promote better healing processes postoperatively.

In contrast, other options do not address the critical need for glucose control. High levels of inflammation, for instance, do not indicate readiness for surgery and can complicate healing if left unmanaged. Stopping all medications may not only disrupt the patient's diabetes management but could also interfere with other health conditions they may have. Lastly, assuming that no special preparation is necessary overlooks the specific adjustments needed for diabetic patients to ensure a safer surgical experience and better healing outcomes.
