Lecture 1 Flashcards
system of tissues that support the teeth
periodontium
covers the root and allows the PDL to attach to the tooth
cementum
Attaches the tooth to alveolar bone or adjacent teeth by anchoring into the cementum and bone
PDL
The areas of bone of the mandible/maxilla that surrounds the roots of the teeth
alveolar bone
the most coronal edge of the gingiva, has a scalloped edge
gingival margain
the most coronal section of gingiva, is not actually attached to the tooth
- surrounds the teeth like the neck of a turtleneck sweater
- the most apical part is called the gingival zenith
marginal “free” gingiva
the “pocket” that is around the teeth like a moat, the depth of this is what is measured during periodontal probing
gingival sulcus
apical to the “free” gingiva. It is firmly attached to the alveolar bone (periosteum) and has a stippled appearance in 40% of adults
attached gingiva
connective tissue covering the bone and has the ability to make new bone
periosteum
the pointy piece of gingiva between the teeth
- It comes to a defined point between teeth in healthy gingiva but in non-healthy gingiva it tends to have a more swollen/bulbous apparency
interdental gingiva
a depressed area of the interdental gingival that is apical to the interproximal contact area. If there is no contact with another tooth the col is not present.
(if you extracted a tooth then looked at the interdental gingiva between the open space and the tooth next to it, you would be able to see it)
Col
the division between free and attached gingiva
free gingival groove
the softer, movable tissue that is apical to the attached gingiva
- Covers the basal part of the alveolar process and continues into the vestibular area on the buccal aspect and the floor of the mouth on the lingual aspect
alveolar mucosa
the junction of the attached gingiva and alveolar mucosa
mucogingival junction
