(a)  

part of oral mucosa that covers alveolar bone and surrounds neck of teeth

(a)  

forms the wall of the sulcus

(a)  

a shallow crevice around tooth that is 2-3mm normal depth

(a)  

bound to underlying bone from mucogingival junction to bottom of sulcus

(a)  

Found in coronal 3rd of root

(a)  

Found in 2/3 of root covering radicular and apex area

(a)  

Sharpey’s fibers entering alveolar bone

(a)  

Serves as protection to developing primary

teeth; support for permanent teeth; resorbs when teeth are lost

(a)  

Outer surface of bone

(a)  

Dense compacts bone

(a)  

(Aging) Gingiva thins out ● softer

● dry

medications induced gingivitis

(a)  

Bleeding upon probing, spontaneous

(a)  

within 4 days of plaque accumulation

● slightly elevated vascular permeability and

vasodilation

● gingival crevicular fluid (GCF) flows out of

sulcus

(a)  

increased vascular permeability, vasodilation,

and GCF flow

● large numbers of neutrophils and lymphocytes

(a)  

How many weeks does it take for collagen destruction to occur in CT

(a)  

2-3 weeks after plaque formation

● increased inflammatory cells (plasma cells,

lymphocytes & neutrophils

● significant collagen depletion of epithelium

● epithelium pockets with large number of

neutrophils

(a)

Give 1 secondary factor that could accelerate the process of periodontitis

(a)  

Excessive cementoblasts deposition

● Concrescence

(a)  

Mass of locations

acellular cementum in abnormal

● Forms when cementoblasts encounters blood clots

(a)  

Trauma induces increased activity among fibroblasts leading to

(a)  

Physiological migration of teeth towards the mesial

● Unbalanced bone remodeling

● Occlusal forces leads to unbalanced cementum

remodeling.
