Which of the following is NOT among the four main impacts of diabetes on intraoral bone healing?

• A. Impaired periodontal bone regeneration
• B. Reduced guided bone regeneration
• C. Delayed healing post-exodontia
• D. Accelerated bone healing

Answer: (D)

Diabetes undermines intraoral bone healing by disrupting several key processes that drive regeneration. In diabetics, healing after dental procedures is typically slowed because hyperglycemia damages small vessels, reducing blood flow and oxygen delivery to healing sites; inflammation tends to be prolonged; osteoblast function is impaired; collagen synthesis and remodeling are disrupted; and advanced glycation end products stiffen the extracellular matrix. These factors collectively blunt bone formation and regeneration in the mouth.

That’s why impaired periodontal bone regeneration, reduced guided bone regeneration, and delayed healing after tooth extraction are observed effects of diabetes. Accelerated bone healing, on the other hand, goes against the expected biology; diabetes more often slows or compromises healing rather than speeding it up. Maintaining good glycemic control can improve healing outcomes by mitigating these negative effects.
