Gingiva of the free faces and interdental space

Gingiva of the free faces and interdental space
The soft tissue that surrounds the teeth is called the gingiva. This is basically classified into the marginal gingiva, which is the tissue found at the border of the teeth and which forms the gingival sulcus, the attached gingiva, which extends to the mucogingival junction, is firm and adherent to the alveolar bone and, finally, the interdental gingiva that, as its name suggests, is found between the teeth. A macroscopic view of the normal gingiva shows it to be of a pale pink color with fine stippling, like the skin of an orange, on the attached gingiva (due to the fibers that insert onto the alveolar bone). In the area of the alveolar mucosa the color is more red. A large number of collagen fibers, called dentogingival fibers, are found within the attached gingiva, running in different directions (1)(2)(4).
