The gingiva and the covering of the hard palate, termed the{{c1:: masticatory mucosa}}
The oral mucous membrane lining the remainder of the oral cavity.
The dorsum of the tongue, covered by {{c1::specialized}} mucosa
The {{c1::gingiva }}is the part of the oral mucosa that covers the alveolar processes of the jaws and surrounds the necks of the teeth

aka {{c3::free}}, {{c3::unatttached}}
In ≅ {{c3::50%}} of cases its demarcated from the attached gingiva by the marginal groove (1mm wide)
forms the {{c3::soft tissue wall}} of the healthy gingival sulcus
separated from the tooth surface with a periodontal probe
the {{c3::terminal edge}} of the gingiva surrounding the teeth

Is continuous with marginal gingiva
firm, resilient and tightly bound to periosteum of alveolar bone.
extends apically to the {{c4::mucogingival junction}} which separates it from the loose and movable alveolar mucosa.
Clinically delineated by depth of the sulcus subtracted from width of the Keratinized gingiva

{{c6::shallow crevice}} or space around the tooth
bounded by surface of tooth on one side and epithelium lining marginal gingiva on the other side
V shaped; barely permits entrance of a periodontal probe.
Sulcus depth can be accurately measured only {{c6::histologically}}
Ideal conditions (only experimentally possible) depth = 0mm; histologically healthy human gingival sulcus mean depth ≅ {{c6::1.8mm}}
Surrogate used clinically = {{c6::Probing depth}}; probing depth in healthy gingiva = {{c6::2-3}}mm
Clinically filled with Gingival crevicular fluid

{{c5::Marginal gingiva}} = Depth of sulcus
{{c5::Attached gingiva}} = Keratinized gingiva – depth of sulcus (Free gingiva).
{{c5::Gingival margin}} – most coronal part of the free or marginal gingiva.
{{c5::Keratinized gingiva}} = Distance from gingival margin to MGJ

In health it fills the gingival embrasure, which is the interproximal space apical to the tooth contact
Can be pyramidal or can have a col shape
Shape of the papillae varies according to {{c7::the dimension of the gingival embrasure}}
