2 Anatomy of the Periodontium Flashcards
What are the 4 main components of the anatomy of the Periodontium?
Gingiva
PDL
Cementum
Alveolar Bone
What are the Tissues of the Periodontium?
Gingiva
Cementum
Periodontal Ligament (PDL)
Alveolar Bone
What is the Gingiva?
The oral masticatory mucosa that
surrounds the cervical portion of teeth and covers the alveolar process of the maxilla and mandible comprised of:
Marginal gingiva (unattached or free gingiva)
Attached gingiva
Alveolar mucosa
Mucogingival junction (MCJ)
Name the following:
What is Marginal Gingiva and where is it found?
What are Lorenzotavelli?
What is the Gingival Margin?
The most coronal portion of the gingiva
Scalloped outline of the teeth
What is the Gingival Sulcus?
The space formed by tooth and sulvular epithelium (laterall) and the coronal end of the JE (Junctional Epithelium?) apically
Sulculear measurements of 1-3mm are considered WNL (Within Normal Limits of Gingival Health)
What is the Free Gingival Groove?
The Free Gingival Groove divides the free gingiva and the attached gingiva
It is a shallow depression
In what percent of patients is a Free Gingival Groove found?
50%
What is the Interdental Gingiva (Interdental Papilla)
Part of the free gingiva
It occupies the interdental space
(fills the embrasure space apical to tooth contact)
Attached to the tooth by the JE (Junctional Epithelium?) and Connective Tissue Fibers
What is the Interdental Gingiva attached by?
Attached to the tooth by the JE (Junctional Epithelium?) and Connective Tissue Fibers
