Occlusion (Lecture 3: Occlusion Related to Periodontics) Exam 1 Study
Guide
1. What is the primary etiology to periodontitis?: plaque
2. the effects induced by normal or excessive occlusal force acting on teeth with decreased
periodontal support: 2º occlusal trauma
3. 2º occlusal trauma acts on teeth with periodontal support: decreased
4. No (<10%) bleeding on probing or bone loss: clinical periodontal health
5. What is the mildest form of gum disease?: gingivitis
6. Symptoms of gingivitis: gums are red, swollen, and bleed easily
- no bone loss
- reversible with professional tx and good at-home oral care
7. Another name for gingival pocket: pseudo-pocket
8. What is the gingival pocket formed by?: gingival enlargement without destruc- tion of underlying
periodontal tissues
- sulcus is deepened because of increased bulk of the gingiva
9. T/F: Gingival pocket (aka "pseudo-pocket") is formed by gingival enlarge- ment WITH
destruction of underlying periodontal tissues.: False! Gingival pock- et is formed by gingival
enlargement WITHOUT destruction of underlying periodon- tal tissues
10.Statement 1: Periodontitis is always preceded by gingivitis Statement 2:
Not all gingivitis progresses to periodontitis.

a. Statement 1 is true, Statement 2 is false
b. Statement 2 is true, Statement 1 is false
c. Both statements are false
d. Both statements are true: d. Both statements are true
11.pathologically deepened gingival sulcus: periodontal pocket
12.What does the periodontal pocket start as?: inflammatory change in connec- tive tissue wall of
the gingival sulcus
- the cellular and fluid inflammatory exudate causes degeneration of surrounding connective tissue
and gingival fibers
- apical to the junctional epithelium, collagen fibers are destroyed
- area is occupied by inflammatory cells and edema
13.What causes degeneration of the surrounding connective tissue and gin- gival fibers?:
cellular and fluid inflammatory exudate
14.Where are collagen fibers destroyed and what is the area occupied by?: -
destroyed APICAL to junctional epithelium
- occupied by inflammatory cells and edema
15.What do bacterial biofilm products induce?: differentiation of bone progenitor cells into
osteoclasts and stimulate gingival cells to release mediators that have the same effect
