42 Cards in this Set

  • Front
  • Back
Healthy gingival characteristics:
1) Color
2) Contour (2 parts)
3) Consistency
4) Miscellaneous (3)
1) Coral pink (not red)
2) Knife-edged gingival margin, stifling (orange peel texture)
3) Firm
4) No bleeding, nice gingival band, no pocket at sulcus
Normal alveolar bone:
1) angle
2) Bony margins
4) Posterior architecture
1) follows CEJ, 1-2 mm away (allows room for attachement (supracrestal))
3) Vertical grooving in alveolar
4) interdental bone is more coronal than FL bone (only slightly in posterior)
How does normal alveolar bone relate to the contour of the CEJ
Follows contour; is apical at midline of tooth, and coronal for proximals
Gingivitis (Definition)
Inflammation of gums. No bone/attachment loss :. reversible.
Gingivities (characteristics):
1) color
2) contour
3) consistancy
4) Misc (1)
1) Bright red
2) adenitis - gingival margin is swollen and rounded at tooth
3) squishy gingival
4) bleeds upon probing
Adenitis: definition and possible causes
swollen rounded gingival margin (?)
Gingivitis, meds, transplant, channel blocks, genetics, etc.
Gingival recession
Exposed CEJ. No blood to epithelium. Gingiva becomes inflammed and breaks down (due to sulcus epithelia going for nutrients). Sulcus epithelia creeps inward and interlocks with oral epithelium, gets strangled :. recession
Periodontitis (Def.)
Bone/attachment loss. Irreversible, but manageable
Gingival pocket. No bone/attachment loss. Gingival swells (:. deep pocket)
Suprabony pocket
Yes Bone/attachment loss. (bone beyond CEJ). Loss is even around perimeter of tooth
Intrabony defect
Loss of attachment, loss of bone deeper in 1 part of alveolar bone beyond CEJ
Probe pressure
How many readings recorded?
Bleeding on Probing (BOP) indicates ____________
Inflammation (NOT necessarily LOA (loss of attachment))
No BOP fairly reliable predictor of ___________
no LOA (loss of attachment)

(BOP - bleeding on probing)
How does smoking effect perio analysis?
Masks periodontal disease b/c nicotine is a vasoconstrictor.
What percentage does nicotine reduce bleeding?
______ ______ is not an accurate basis for diagnosis of periodontal disease. Use _________ ________ instead
Probing depth; attachment level
loss of alveolar bone on buccal or lingual side that is continuous w/ bony margin
Loss of alveolar bon on buccal or lingual side NOT continuous with bony margin (has "window")
Reverse architecture (Osseous Form)
Interdental bone more apical to FL bone
"Tunnel" can be seen btw roots of tooth due to bone/attachment loss
Furcations: Maxillary 1st premolars
Takes lots of bone/attachment loss b/c roots (facial/palatal) are connected low.
Makes for mesial and distal furcations at middle and apical 1/3s of root
Furcations: Maxillary molars
3 roots. 3 furcas: Facial, distal, mesial
Furcas: Mandib. molars
Mesial and distal roots. Facial/lingual furcations at mid tooth (?).
Furcation involvement:
1) Incipient
2) Definite
3) Through and through
1) Fit the tip
2) Fit the tip deeper
3) all the way through
Testing for mobility: How and classifications
Attempt to move tooth BL direction with 2 instruments.
Class 1 - >1mm
Class 2 - <1mm
Class 3 - <1mm and depressable
Genetic test for people genetically susceptible to perio disease
Gingival-Crevicular Fluid Analysis
heavier flow if infected (?)
4 basic perio anatomy components
1) Gingiva - mucosal tissue over alveolar bone
2) PDL (periodontal ligament). Specialized conn. tissue fibers that attach tooth to alveolar bone
3) Cementum - outer root shell
4) Alveolar bone - ridge of bone with tooth sockets
Area btw sulcular epithelium and tooth. Not attached
OE (Oral Epithelium)
Keratinized epithelium tissue with reedy pegs on inside
Lamina propila
N. Connective tissue. btw OE and JE/SE.
Connective tissue papilla
Pegs at interface with oral epithelium
sulcular Epithelium
no keratination, not attached to tooth. No reedy pegs (unless inflammed
Junctional Epithelium (JE)
initial attachment to tooth. If inflammed, reedy ridges break down quickly. No keratinization. Two basal laminas - external/internal. Circular fibers and transseptal fibers
Transseptal fibers
In junctional epith. Connect between proximal region of teeth
Epithelia: Basal lamina attaches to epithelium via _______________. Basal cell layer connects to one onother via ____________
hemidesmosomes; desmosomes
Supracrestal Connective Tissue
tooth attachment; very strong (?)
Mucogingival Junction
where attached gingiva meets unattached (alveolar) mucosa
Depression in interdental gingiva directly apical to contact of 2 adjacent teeth
(not present if adjacent teeth are not in contact or if gingiva has receded.
Cementum (2)
1) Acellular - no more remodeling after apex

2) Cellular - constant remodeling at apex
