a pocket formed by gingival enlargment without apical migration of the junctional epithelium
What 2 types are pockets divided into?
are deep perio structures involved in gingival pockets?
What type of tooth wall is in gingival pockets?
Where is the base of the sulcus in a gingival pocket?
near the cementoenamel junction
What is the pockets position in relation to the alveolar bone? (suprabony or intrabony)
ALL gingival pockets are suprabony
the base of the pocket is coronal to the crest of the alveolar bone
Pocket formed as a result of disease that causes the junctional epithelium to migrate apically along the cementum
Is the attachment apparatus (periodontal ligament, cementum, alveolar bone) involved in periodontal pockets?
What is the tooth wall in a periodontal pocket?
- or part cementum and part enamel
Where is the base of the pocket in a periodontal pocket?
on the cementum at the level of attached periodontal tissue
are periodontal pockets subra or intrabony
they may be either one of them
pocket in which the base of the pocket is below, or apical to the crest of the alveolar bone
Is a periodontal pocket wide or narrow?
The periodontal pocket epithelial lining is_________to and follows the_______of the tooth
true or false. When calculus deposits are present in the periodontal pocket, the pocket wall will follow the contour of the calculus
true or false. The deeper the periodontal pocket, the less it can be cleaned by a tooth brush
What are 5 substances that can be found in a periodontal pocket?
- epithelial cells
- purulent exudate
The periodontal pocket deepens as a result of continuing action of the________and _________ from dental biofilm
- destructive agents
The periodontal ligament fibers in a periodontal pocket become________and the junctional epithelium migrates________
What are 3 different changes that alter the cementum in a periodontal pocket?
What are 4 surface changes that occur in periodontal pockets as a result of the exchange of minerals with oral fluids and exposure to biofilm bacteria?
- hypermineralization of calc on cementum
- calculus formation - in layers
- dental biofilm and debris collection
How are surface irregulatories detected supragingivally?
drying the surface and observing it under adequate light
How are surface irregularities detected subgingivally?
tactile and auditory sensitivity with a probe or explorer
What are 5 causes of surface roughness on enamel?
- structural defects - cracks and grooves
- demineralization - cavities
- calculus and stain
- erosion and abrasion
- hypoplasia pits
What are 3 causes of surface roughness on the CEJ?
What percent of teeth have a CEJ with:
What are 6 causes of surface roughness on the root surfaces?
- diseased cementum
- root caries
- overhang restorations
- grooves from previous instrumentation
