detection and prevention of periodontal disease in diabetes
Normal periodontium includes gingiva, periodontal ligament, cementum, and alveolar bone. It is supplied by the vasculature and affected by bacterial plaque that accumulates at the junction between the teeth and the gingiva.
This cross-sectional slide illustrates major tooth components:
- Enamel, the hardest substance in the body, forms the outer covering of the tooth.
- Dentin is the hard tissue that comprises the bulk of the inner tooth.
- Pulp, the soft tissue of the tooth, contains the blood vascular system and nerve tissue.
- Cementum is a hard tissue that covers the tooth root.
- Periodontal ligament is composed primarily of collagen fibers, which attach the tooth root to the supporting alveolar bone and gingival tissues.
