Treatment of Physiologic Gingival Pigmentation with Surgical Blade: A 25-Year Follow-up
Abstract:
Gingival hyperpigmentation in the anterior region in people with a high smile line is an esthetic concern. Gingival depigmentation can be achieved through various procedures. Most techniques have shown successful short-term results; however, recurrence is observed in 50% of patients after 2 to 4 years. A 46-year-old woman presenting with a large black zone of gingival hyperpigmentation in the anterior maxilla was treated with scalpel blade excision. At 25 years after the depigmentation procedure, the patient displayed no recurrence.

Liver Physiology
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of 70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...
