Core Tip

Core Tip: Periodontitis is a frequent but often overlooked complication of type 2 diabetes, arising from chronic metabolic and inflammatory imbalance. Real-world evidence suggests that improving metabolic and inflammatory regulation may reduce periodontal complications and support overall health. Recognizing oral health as an essential part of comprehensive diabetes care highlights the importance of interdisciplinary collaboration between endocrinology and dentistry for better patient outcomes.
