periodontal dz Flashcards
most common oral disease and cause of tooth loss
periodontal disease
mineralized plaque containing bacteria which release endotoxins that cause gingivitis
calculus / tartar
if gingivitis is left untreated the inflammatory response results in the destruction of what atteachment
junctional epithelium and epithelial attachment – at the base of the gingiva sulcus exposing the periodontium
list diseases that exacerbate the periodontal disease
neutrophil dysfunction diabetes mellitus cushings autoimmune calicivirus xerostomia
how does periodontal disease lead to implications such as chronic nephritis, hepatopathies and endocarditis
chronic showering of bacteria into circulation
T/F
both gingivitis and periodontal disease are reversible
false - only ginigivits is
clinical signs of periodontal disease
halitosis accumulation of plaque excessive salivation loose teeth low appetite - uncommon oral discomfort
what + attachement loss
the recession measurement + pocket depth
periodontal stage 0
normal gingiva
periodontal stage 1
ginigivitis only - erythema
bleeds when probed
normal sulcus depth
no attachment loss
periodontal stage 2
<25% attachment loss
early periodontitis
can be controlled but not reversed
periodontal stage 3
25 - 50% attachment loss
horizontal and vertical bone loss
periodontal stage 4
> 50% loss - tooth will be lost
periapical lucencies
furcation stage 0
no furcation involvement
furcation stage 1
incipient - probe can enter to depth <1mm - soft tissue only
furcation stage 2
definite - probe can enter >1 mm - bone loss
furcation stage 3
through and through - probe passes horizontally through furcations
M0
normal physiologic mobilitity
up to .2mm
M1
mild pathologic mobility
.2 - .5 mm
M2
moderate pathologic mobility
.5 - 1 mm
M3
severe
>1 mm or any axial movement
normal dog sulcus depth
1 -3 mm
normal cat sulcus depth
0 - 1 mm
goal of periodnotal treatment
prevent development of new lesions at other sites and to prevent further tissue destruction at sites already affects
remove biofilms
minimize attachment loss
maintain adequately attached gingiva
