Name: Score:117 Multiple choice questions
Term 1 of 117
The epithelial lining of gingival sulcus. It is continuous with the oral epithelium and extends from
the crest of the gingival margin to the coronal edge of the JE
(Epithelium that lines the sulcus)
Allergic reactions
Free gingiva
Gingival Fibromatosis
Sulcular Epithelium
Term 2 of 117
(Microscopical pic of periodontitis) The JE proliferates and extends epithelial ridges into
connective tissue. The sulcular epithelium of the pocket wall thickens and extends epithelial
ridges deep into the connective tissue. Small ulcerations of the pocket epithelium expose the
underlying inflamed connective tissue.

How we treat periodontal disease now
PDL Fibers
Epithelial-Connective Tissue Junction
,Term 3 of 117
Medications used for chest pain and hypertension, relaxes blood vessels and increases supply of
blood and oxygen
Calcium channel blockers (amlodipine, nifedipine, verapamil)
Alveolar bone
Anticonvulsants (Phenytoin, Celontin, Depakote)
Necrotizing Periodontal diseases

how we treat periodontal disease now
Most common type of periodontitis
In health the interdental gingiva:
Intermittent Progression Theory
Periodontium location
Term 5 of 117
Stages of disease in the JE: Gingivitis
from plaque-induced gingivitis
Plaque-induced gingivitis
Migrates apically, forms a pocket
JE sits at the cementum
,Definition 6 of 117
Interdental papilla
Portion of gingiva that fills the interdental embrasure between two adjacent teeth apical to
contact area. Prevents food from becoming packed between the teeth during mastication.
Formed by free gingiva from adjacent teeth, portion of gingiva that fills up embrasures
between teeth
The sequence of events that occur during the development of disease or an abnormal
condition
The specialized epithelium that forms the base of the sulcus and joins the gingiva to the
tooth surface
Term 7 of 117
Periodontitis symptoms
- red/purplish tender gums
- bleeding
- swelling
How we used treat periodontal disease
-supportive
-sensory
-nutritive
-formative
-remodeling
Immunosuppressants (cyclosporine)
, Term 8 of 117
Cementum functions
-Reinforce JE to tooth
-Provide free gingiva with rigidity to withstand masticatory forces
-Unite free gingiva with cementum and alveolar bone
-Connect tooth to tooth to maintain positioning in arch
(Cementum is formed throughout life and increases in thickness)
- important for the quality of healing at completion of periodontal treatment
- necessary for new attachment and as a source of growth factors
- induce PDL regeneration when needed.
JE at CEJ
The PDL is able to dissolve the bone adjacent to the tooth and give a clear path of
movement. Once the tooth is done moving, the PDL regenerates the alveolar bone in that
new position (this is what occurs during ortho treatment)
Definition 9 of 117
Alveolar bone proper (cribriform plate)
Characterized by periods of disease activity and inactivity (remission)
thin layer of bone that lines the socket that surrounds root of tooth
Bone that surrounds the roots of the teeth, forms bony sockets that protect the root
The lattice-like bone that fills the interior portion of alveolar process, oriented around
tooth to form support for the alveolar bone proper
