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 3)Grooving 4) Posterior architecture |
1) follows CEJ, 1-2 mm away (allows room for attachement (supracrestal))
2)Thin 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
|
|
Periodontitis:
Pseudopocket |
Gingival pocket. No bone/attachment loss. Gingival swells (:. deep pocket)
|
|
Periodontitis:
Suprabony pocket |
Yes Bone/attachment loss. (bone beyond CEJ). Loss is even around perimeter of tooth
|
|
Periodontitis:
Intrabony defect |
Loss of attachment, loss of bone deeper in 1 part of alveolar bone beyond CEJ
|
|
Probe pressure
|
10-20g
|
|
How many readings recorded?
|
6
|
|
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?
|
50%
|
|
______ ______ is not an accurate basis for diagnosis of periodontal disease. Use _________ ________ instead
|
Probing depth; attachment level
|
|
dihiscence
|
loss of alveolar bone on buccal or lingual side that is continuous w/ bony margin
|
|
Fenestration
|
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
|
|
Furcation
|
"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 |
|
PST
|
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 |
|
Sulcus
|
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
