2. Not caused by periodontal disease so, the patient doesn’t have pockets etc. It is caused by aggressive brushing/ orthodontic treatment if the tooth is pushed too forward/ bony deficiency

3. What is the gingival sulcus?
3. The groove between the gingival margin and the tooth enamel
3 of 16
4. What is the junctional epithelium?
4. The base of the gingival sulcus, where plaque bacteria and their toxins leak and go into the gingival CT and cause inflammation. It is the weak point in the gingival barrier against invading plaque

5. What are the two types of histological clinical gingival health?
5. Pristine gingival health and clinically healthy gingiva

6. What is pristine gingival health and what is clinically healthy gingiva?
6. Long term excellent oral hygiene and adequate levels of oral hygiene mainted

7. What is inflammatory infiltrate in the connective tissue underlying the junctional epithelium?
7. Mainly neutrophils but may include some macrophages and lymphocytes like b cells
7 of 16
8. Features of pristine gingival health
8. No signs of inflammation, no bleeding on probing, no loss of attachment, virtually zero plaque scores, free gingival groove likely to be seen, pocket depths 3mm or less

9. Features of clinically healthy gingiva
9. Clinical features similar to pristine gingival health, but there may be some evidence of localised inflammation

10. What us gingival crevicular fluid? What what causes its formation?
10. It is a serum like fluid formed from the post capillary venules of the dentogingival plexus. Formed by the ongoing low level inflamtory reaction in the ct underlying the junctional epithelium .

11. What is the dentogingival plexus
11. Is a dense network of blood vessels in the gingival ct subadjacent to the. Junctional epithelium
11 of 16
12. What does the gingival crevicular fluid contain?
12. Various plasma proteins, defence cells like antibodies, complement – these help to combat the potentially invading plaque bacteria
12 of 16
13. What are some of the mechanisms to prevent bacterial invasion?
13. Outward flow of GCF into the gingival sulcus. High turnover of junctional epithelial cells. Killing of micro organisms by inflammatory and immune cells. Destructions of micro organisms by immunoglobulins/ activation of the complement system. Norm

14. When does the clinical gingival health occur?
14. Clinical gingival health on an intact periodontium- there has been no previous periodontitis, therefore there is no loss of attachment. Clinical gingival health on a reduced periodontium – reduced periodontium refers to the presence of LOA,

15. What is considered normal and consistent with clinical health in the 2017 perio classification?
15. The presence of low levels of bleeding in probing (less than 10% of the sites) in pockets 4mm or less ( but no bleeding on probing in the 4mm pockets) is considered normal and consisten with clinical health- part of the concept of physiological i
