Review of Periodontal Structures Flashcards
List the components of the periodontium
Gingiva
PDL
Cementum
Alveolar Bone
List and define the 3 types of mucosa, and provide
examples of each
Masticatory: Hard Palate, Attached gingiva
Lining Mucosa: Stretch, Floor of mouth, soft palate
Specialized Mucosa: Dorsum of tongue
Identify which structure/feature creates the
appearance of stippling
Rete Pegs
Define the function of and identify the contents of
GCF
Function: Transport antibodies and cellular components
Fluid contains: Bacteria, epithelial cells, leukocytes, minerals, nutrients
Define and describe supracrestal attached tissues
(previously biologic width), and discuss its
importance in restorative dentistry
-Dentogingival unit
composed of the gingival connective tissue attachment and the junctional epithelium
- Combo of height of the gingival connective tissue and the JE
fills the sulcus; flows
through the tissues into the sulcus (originates from BV in
CT)
Gingival crevicular fluid (GCF)
continuous with free gingiva, tightly
adhered to underlying cementum and periosteum (CT)
Attached Gingiva
Between the teeth
Interdental Papilla
forms a “seal” at the gingival crevice to hold it firmly in place
Junctional Epithelium
Alveolar Crest Horizontal Group Oblique Group Apical Group Interradicular group
5 groups of PDL
Primary component in PDL is ___ made by what cell
Fibroblasts make collagen fibers
the part of the periodontium
that attaches the teeth to the alveolar bone
by anchoring the periodontal ligament; hard
tissue, thickest at the apex; covers the root of
the tooth l Composed of mineralized fibrous matrix and
cells l Fibrous matrix = Sharpey’s fibers + non-
periodontal fibers
Cementum
portion that contains the roots
of the teeth
Alveolar bone/process
part of the alveolar
bone that is the tooth “socket”; (cortical bone lining
sockets)
Alveolus (alveolar bone proper)
portion of bone apical to roots
Basal Bone
