D514 Gingiva and Epithelial Attachment Exam
Questions and Answers | Verified
parts of the periodontum
PDL, cementum, gingiva, alveolar bone
gingiva
portion of oral mucosa that surrounds the neck of the teeth (like a collar) and covers alveolar
process
3 zones of gingiva
free or marginal
attached
interdental
free or marginal gingiva
circles the tooth
defines the gingival sulcus
unattached -> can insert periodontal probe
attached gingiva
-firmly attached to underlying alveolar bone
-joined to tooth by junctional epithelium
-extends from end of free/marginal gingiva (free gingival groove) to mucogingigval junction
-firm and immoveable
interdental gingiva
-space b/w two adjacent teeth apical to contact area
, -wedge shaped zones
-seen in the gingival embrasure
alveolar mucosa
Mucosa between the mucobuccal fold and gingiva.
differences between gingiva and alveolar mucosa
-Gingiva: Part of masticatory mucosa, Keratinized stratified squamous epithelium, Thicker
epithelium; blood vessels are not visible, Appears pale pink due to keratinization
-Alveolar Mucosa: Part of lining mucosa, Non-keratinized stratified squamous
epithelium, Thinner epithelium; blood vessels in the lamina propria are visible,
Appears reddish due to lack of keratinization
4 distinct boundaries of free/marginal gingiva
-coronally - gingival margin
-apically - free gingival groove
-inner margin - gingival sulcus or sulcular eipthelium
-outer surface - oral cavity and vestibule
coronal boundary of free/marginal gingiva
gingival margin
apical boundary of free/marginal gingiva
free gingival groove
inner boundary (tooth surface side) of free/marginal gingiva
forms soft tissue wall of gingival sulcus (green) w/ sulcular epithelium (pink)
outer surface boundary of free/marginal gingiva
