Study Notes
Hormonal Disorders
- Periodontal disease is linked to bacterial injury, but the host's immune response plays a significant role in disease severity.
- Systemic disorders don't initiate chronic periodontitis, but they can accelerate its progression.
Diabetes Mellitus
- Characterized by chronic hyperglycemia due to insulin deficiency.
- Affects lipid and protein metabolism.
- Uncontrolled diabetes can lead to complications in the eyes, kidneys, nervous system, vasculature, and periodontium.
Periodontal Manifestations
- Severe gingival inflammatory response to bacterial plaque.
- Enlarged gingiva.
- Sessile or pedunculated gingival polyps.
- Multiple periodontal abscesses.
- Periodontitis with periodontal pocketing.
- Persistent gingival inflammation after periodontal treatment.
- Continued alveolar bone loss despite treatment.
- Increased tooth mobility and migration.
How Diabetes Influences the Periodontium
- Bacterial Pathogens: While some studies indicated higher proportions of certain bacteria in diabetic patients, later research suggests no significant difference in bacterial types between diabetic and non-diabetic individuals.
- Changes in Periodontal Vasculature: Advanced Glycation End-products (AGEs) form due to excessive glucose in the blood. AGEs accumulation in periodontal vasculature can:
- Affect endothelial cell function, capillary growth, and vessel proliferation.
- Increase vessel wall thickness, narrowing the lumen and altering periodontal tissue homeostasis.
- Enhance cross-linking of AGE-containing collagen in the basement membrane, impacting membrane thickness and nutrient provision.
- Altered Immune Response: Diabetic patients show altered function of immune cells, including:
- Neutrophils: Impaired adherence, chemotaxis, and phagocytosis.
- Monocytes & Macrophages: Elevated production of proinflammatory cytokines due to AGE-RAGE interaction.
- Impaired Bone Formation: Reduced bone remodeling primarily due to decreased osteoblast function.
- Altered Collagen Metabolism: High glucose environments impair fibroblast function. Increased production of matrix metalloproteinases leads to rapid collagen degradation.
