Gingival margin
Gingival Margin[edit | edit source]
The gingival margin is the most coronal point of the gingiva, or gum tissue, surrounding the teeth. It is an important anatomical feature in the oral cavity and plays a crucial role in dental health.
Anatomy[edit | edit source]
The gingival margin is the edge of the gingiva that is closest to the biting surface of the teeth. It forms the boundary between the free gingiva and the attached gingiva. The free gingiva is the part of the gingiva that surrounds the tooth and is not directly attached to the tooth surface, while the attached gingiva is firmly bound to the underlying alveolar bone.
Function[edit | edit source]
The gingival margin serves as a protective barrier for the underlying periodontium, which includes the cementum, periodontal ligament, and alveolar bone. It helps to prevent the invasion of bacteria and other pathogens into the deeper structures of the periodontium.
Clinical Significance[edit | edit source]
The health of the gingival margin is a key indicator of overall periodontal health. Inflammation or recession of the gingival margin can be a sign of gingivitis or periodontitis, which are common periodontal diseases.
Gingival Recession[edit | edit source]
Gingival recession occurs when the gingival margin moves apically, exposing the root surface of the tooth. This can lead to increased sensitivity, risk of root caries, and aesthetic concerns. Causes of gingival recession include periodontal disease, aggressive tooth brushing, and trauma.
Gingival Inflammation[edit | edit source]
Inflammation of the gingival margin, known as gingivitis, is characterized by redness, swelling, and bleeding of the gums. It is often caused by the accumulation of dental plaque and can progress to periodontitis if left untreated.
Maintenance[edit | edit source]
Proper oral hygiene practices, such as regular tooth brushing and flossing, are essential for maintaining the health of the gingival margin. Regular dental check-ups and professional cleanings can help prevent and manage gingival and periodontal diseases.
