11/5: Interpretation of Perio Disease Flashcards
destructive inflammatory disease affecting supporting structures of the teeth
periodontal disease
only soft tissues involved
gingivits
soft tissues and supporting bone affected
periodontitis
major cause of tooth loss over 35
periodontal disease
severity of periodontal disease depends on
age
plaque
biofilm flora
what are the predisposing factors?
plaque
salivary immune factors
cell mediated hypersensitivity with crevicular plaque
local dental factors
list the local dental factors
poor restoration
calculus
tilted/rotated tooth
thin bone
what are the clinical signs of periodontal disease (NOT RADIOGRAPHICAL)
edema/erythrema
loss of epithelial attachment and pocket formation
bleeding on probing
purulence
what is a favorable immune response?
pink gums
what are you looking for in the bone when doing radiograph exam?
quanity based on root length
quantity based on crestal evaulation
quality
furcation
PDL space
this is >75% of existing dentition
generalized
what are we looking for on the roots?
length
shape
crown:root ratio
do we look for proximity of roots to other teeth?
Yes
types of root shapes?
converging
diverging
dilaceration
this is an abnormal angulation in the root, usually caused by trauma, idiopathic
dilaceration
what can support teeth during perio disease?
dilaceration
hypercementosis
calculus can be best demonstrated with what?
brightness
this is uniform apical movement of the alveolar crestal bone between adjacent teeth
HBL
this is space within unerupted teeth
follicular space
what is HEALTHY posterior dentition?
flat, cortical bone
<2mm from CEJ
what is healthy anterior dentition?
pointed, cortical bone
<2mm
this is slight crestal bone loss, <20% (1-2mm)
incipient bone loss
this is 20%-50% bone loss
moderate bone loss
this is 50% or more bone loss and VBD
advanced bone loss
in anterior incipient bone loss, what do you see?
blunted peaks, non-corticated bone
healthy
incipient bone loss
moderate bone loss
moderate bone loss
advanced bone loss
advanced bone loss
within physiological levels
this is angular bone loss along a root that more severely involves teh affected tooth than adjacent teeth
VBL
this is loss of bone in the furcation area of a multi-rooted tooth
furcation defect
can a furcation defect occur with a HBL or VBL?
both
VBL with furcation defect
how much deminerlization is necessary for radiographic changes?
40-50%
can you observe 2-D infra-bony defects with radiographs?
very hard
what are radiographic limitations?
40-50% deminerlization
2-D infrabony defect hard to see
No soft tissue visibility
hard to see B/Li surfaces
mobility
what are perio disease tx options?
plaque control
antimicrobial agents
professional cleaning
surgical techniques
will you ever get real image of cervical spine?
no
