Micronutrients and the Periodontium: A Narrative Review.

This is a comprehensive narrative assessment of micronutrient relevance for periodontal health. The periodontium is a crucial and intricate structure that supports the tooth within the alveolar bone. Composed of four tissues with distinct embryological origins- the alveolar bone, cementum, gingiva, and periodontal ligament - the periodontium plays a fundamental role in maintaining dento-alveolar function and homeostasis. Periodontitis is gaining attention due to its widespread occurrence worldwide. This inflammatory condition disrupts the balance between the host immune response and microbial virulence factors. Connective tissue production and host defenses require proteins for periodontal health. Vegetable proteins support periodontal health by promoting tissue repair and immune function, while excessive dietary fats can exacerbate inflammation and increase the risk of periodontal disease (PD). Inflammation is further compounded due to dietary animal fats, which contribute to the risk of PD. Omega-3 fatty acids are well-known for their anti-inflammatory effects, which help reduce periodontal inflammation. Adequate intake of essential minerals and vitamins is required for maintaining periodontal health. Vitamins K, D, and A are crucial in maintaining oral epithelial integrity, facilitating bone development, and supporting overall tissue maintenance. Inadequate calcium (Ca²⁺) and magnesium (Mg²⁺) levels have been associated with severe PD. Antioxidants such as vitamin C help alleviate inflammation in periodontal tissues. As recognized by dental professionals, nutritional status plays a considerable role in an individual's risk of developing PD.
