DH100: Chapter 14: The periodontium Flashcards
clinical treatment procedure are applied.
clinical crown
periodontal fibers are attached.
clinical root
part of tooth covered by enamel
anatomical crown
tooth covered by cementum
anatomic root
lining of the oral cavity, a mucous membrane composed of connective tissue covered with stratified squamous epithelium
oral mucosa
covers the gingiva and the hard palate, areas most used during the mastication of food.
masticatory mucosa
covers the inner surface of the lips and cheeks, floor of the mouth, underside of tongue, soft palate and alveolar mucosa.
lining mucosa
covers the dorsum of tongue. Composed of many papillae. Contain taste buds.
specialized mucosa
threadlike keratinized elevations cover the dorsal surface of tongue; most numerous of papillae.
filiform
mushroom-shaped papillae interspersed among the filiform papillae on the tip of tongue.
fungiform
10-14large round papillae arranged in a “V” between the body of tongue and the base. Taste buds line the walls.
circumvallate
vertical grooves on lateral posterior side of tongue; contain taste buds.
foliate
fibrous connective tissue that surrounds and attaches the roots of teeth to alveolar bone.
periodontal ligament
free gingiva; from cementum in the cervical region to the free gingiva to give support to the gingival.
dentogingival fibers
attached gingiva; fr alveolar crest into the free and attached gingiva tor provide support.
alveologingival fibers
circular; continuous around the neck of the tooth to help maintain the tooth in position.
circumferential fibers
alveolar crest; fr the cervical cementum over the alveolar crest to blend with fibers of the periosteum of bone.
dentoperiosteal fibers
fr the cervical rea of one tooth across to an adjacent tooth to provide resistance to separation of teeth.
transseptal fibers
also called dentoalveolar fiber group.
principal fiber group
fr the root apex to adj. surrounding bone to resist vertical forces.
apical fibers
fr. the root above the apical fibers obliquely toward the occlusal to resist vertical and unexpected strong forces.
oblique fibers
fr. the cementum in the middle of each root to adj. alveolar bone to resis2t tipping of the tooth.
horizontal fibers
fr. alveolar crest to the cementum just below the CEJ to resist intrusive forces.
alveolar crest fibers
fr. cementum between the roots of multirooted teeth to adj. bone to resist vertical and later forces.
interradicular fibers
thin layer of calcified connective tissue that covers the tooth from the CEJ to, and around, the apical foramen.
-seal tubules of root dentin; attachement for periodontal fibe rgrps.
50-200 um about the apex; 30-60 about cervical area
-insensitive
cementum
consist of lamina dura, surrounds tooth socket and supporting bone.
-support teeth and provide attachment for periodontal ligament fibers.
alveolar bone
- adapted around each tooth. connects attached gingiva at the free gingival groove and attaches to the tooth at coronal portion o junctional epithelium.
free gingiva (marginal gingiva)
shallow linear groove that demarcates the free from the attached gingiva.
free gingival groove
covers the free gingiva from the gingival groove over the gingival margin
oral epithelium
edge of the gingiva nearest the incisal or occlusal surface
gingival margin
crevice or groove bet. the free gingiva and the tooth.
gingival sulcus
base of the sulcus or pocket is also called?
probing depth, depth of sulcus, bottom of the pocket
cont. of oral epithetlium covering the free gingiva.
sulcular epithelium
depth of sulcus?
0.5mm, shallow; ave. healthy is 1.8 mm.
serum like fluid that seeps the connective tissue through the epithelial lining of sulcus or pocket.
gingival sulcus fluid.
cufflike band of stratified squam. epithelium that is continuous with the sulcular epithelium and completely encircles the tooth.
- 1-20 cells in thickness
- attachment is on enamel
junctional epithelium
interproximal area is also called
embrasure
depression under a contact area bet. a lingual or palatal and facial papilla that conforms to the proximal contact area.
col
continuous with the oral epithelium of the free gingiva is covered w/ keratinized stratified squa. epithelium.
attached gingiva
line that marks the connection bet. the attached gingiva and the alveolar mucosa.
-found on facial surface of all quadrants and on the lingual surface of mand. arch.
mucogingival junction
movable tissue loosely attached to the underlying bone.
alveolar mucosa
narrow fols fo of mucous membrane passes from amore fixed to a movable part.
-midline bet central incisors
frenum
expressed as slight, moderate or severe
severity
