Applied Anatomy of the Periodontium

what two things make up the keratinized gingiva?

attached and marginal gingiva
what is the marginal gingiva?

sulcus
in a healthy individual, where does the probe penetrate to?

free gingival groove
in a diseased patient, where does the probe penetrate to?

past the JE and into the CT
Where is the JE when a tooth is erupting?

slightly covering the enamel
when is the JE apical to the CEJ?

supraeruption or periodontitis
Define true pocket

JE has moved apical to CEJ but free gingiva has remained tall
Define False Pocket

JE is still at the CEJ but the free gingiva has undergone hyperplasia making it taller and causing gingival excess
What can cause necrosis of the JE?

immunocompromised patients (HIV)
define biologic width

distance from CEJ to alveolar crest has to be at least 3mm
how does resistance to attachment loss for thin gingival phenotypes compare with that of normal patients?

same resistance to attachment loss but the thin gingiva cannot protect against friction as well.
List 3 ways in which thin gingiva can facilitate subgingival plaque formation
- 1. mobile tissue causes pocket to open
- 2. facilitates food impaction
- 3. impedes oral hygiene
list 3 results of thin phenotype
- 1. increased recession
- 2. more vulnerable to trauma
- 3. more inflammation
when are gingival grafts indicated?

when recession causes symptoms such as caries, esthetics, progressive recession or sensitivity
what type of crown margin is used for thin phenotypes?

subgingival
