The ginigiva is the part of the oral mucosa, which covers the alveolar process/ processus alveolaris. The keratinized attached gingiva is firmly bound to the underlaying periosteum of the alveolar bone and therefore non-relocatable. Its appearance is paler than the other oral mucosa and normally displays a surface stippling. Located between the teeth, the interdental gingiva forms a papillae in either pyramidal or "col" shape. The so called free or marginal gingiva represents the terminal 0.5 to 2mm border of the gingiva and surrounds the teeth. Its tissue is mobile and shows no stippling.
