|
Gingiva
|
Provides a tissue seal around the cervical portion of the tooth
holds the tissue against the tooth during mastication
|
|
PDL function
|
Suspends and maintains the tooth in its socket
|
|
Cementum
|
Anchors the ends of the PDL fibers to the tooth so that the tooth stays in its socket
|
|
Alveolar Bone
|
Surrounds and supports the roots of the tooth
|
|
4 anatomical areas of gingiva
|
Free gingiva
attached gingiva
interdental gingiva
gingival sulcus
|
|
Coronal boundary of the gingiva
|
Gingival margin
|
|
Apical boundary of gingiva
|
Alveolar mucosa
|
|
Linear depression seperating the free and attached gingiva
|
Free gingival groove
|
|
Clinically visible boundary where the attached gingiva meets the alveolar mucosa
|
Mucogingival junction
|
|
Located coronal to the CEJ, forms the soft tissue wall of the gingival sulcus
|
Free gingiva
|
|
Part of the gingiva that is tightly connected to the cementum on the cervical third of the root and to the periosteum of the alveolar bone
|
Attached gingiva
|
|
Where is the attached gingiva widest?
|
Molar and incisor regions
|
|
Where is the attached gingiva narrowest?
|
Premolar regions
|
|
Stippling
|
Presence of connective fibers that attach the gingival tissue to the cementum and bone.
