Dental Flashcards
Gingiva
Oral mm
Covers the jaw bone
Gingival Sulcus
Area between gingiva and neck of the tooth
Neck
Area of the tooth where the crown and root meet
Cementum
Covers the root
Dentin
Porus, boney substance beneath enamel and cementum
Pulp Cavity
The center chamber of tooth houses nerves and blood supply; beneath dentin
Apical Delta
Area where blood and nerves exit the tooth
Periodontal Ligament
Holds tooth to the jaw bone
Labial
Comes in contact with the lips
incisors-surface
Palatal
Comes in contact with the pallet
maxillary teeth
Lingual
Surface towards tongue
mandibular teeth-inside
Buccal
Surface in contact with cheek
canine, premolar, molar
Mesial
In reference to individual tooth
toward the mid-line
Distal
Surface away from the mid-line
away from the mid-line
Distal
Surface away from mid-line
away from mid-line
Enamel
Substance that covers the crown
hardest substance

Crown status measurement
Gives general assessment of the amount of calculus on the tooth
C/S
Calculus slight
C/M
Calculus moderate
C/H
Calculus heavy
Furcation
Area where the root joins the crown on a multiple rooted tooth
F1
Can be detected by the probe
F2
Probe passes into furcation half-way
F3
Probe passes all the way through
Gingival recession
Measures the amount of recession from CEJ
Tooth mobility
Results from changes in ligament
M1
Slight mobility
M2
Increased mobility
0.3-1mm in each direction
M3
Increased mobility
loss of 2/3 of periodontal attachment
M4
Vertical mobility
Grey or brown
Loss of function
