Week 3: Staging/Grading Flashcards
previously used periodontal classification system
AAP 1997
AAP 2017 includes health for what?
dental implants
categories of periodontal health, gingival disease/conditions
- periodontal and gingival health
- gingivitis: dental biofilm induced
- gingival disease: non-dental biofilm induced
categories of periodontitis
- necrotizing periodontal disease
- periodontitis
- periodontitis as a manifestation of systemic disease
stable vs unstable, health on reduced periodontium
based on BOP; <10% BOP
stage/grade with patients who have
CAL
- associated with biofilm alone
- systemic/local risk factors can mediate
- drug-induced gingival enlargemetn
dental biofilm induced gingivitis
examples of causes for non-dental biofilm induced gingivitis
genetic/developmental, endocrine/nutrition, neoplasms, immune conditions
scaling in the presence of gingivitis code
D4346
D4346 must have ___ of periodontitis, and won’t require _____
absence, staging/grading
periodontitis
-have CAL on 2 or more non-adjacent teeth
-Bu & Li CAL greater than or 3mm PLUS pocketing greater tha nor equal to 3 mm on 2 or more teeth
AND
-have radiographic bone loss
stages of periodontitis
I, II, III, IV
patients do not _____ to lower stage
retrogress
components of staging
severity, complexity, extent/distribution
stage I and II usually have ___ bone loss
horizontal
stage III and IV usually have ___ bone loss
vertical
class II or III furcation involvement bumps a patient to an automatic
stage III
usually it only takes __ complexity factor to bump a patient up a stage
one
stage I and II patients have ____ due to periodontitis
no tooth loss
normal physiological bone loss is…
1-3mm apical to CEJ
coronal 1/3 bone loss =
middle 1/3 and beyond bone loss =
stage I/II
stage III/IV
indicator of the rate of periodontitis progression
grading
indirect evidence examples
radiographic bone loss/age = %
assume everyone is at _____, and seek evidence to shift
Grade B (moderate rate)
True/false, grading can be modified on the presence of risk factors (ex, Grade C to Grade A)
true
example calculation ratio of RBL
% bone loss of root length = 40
patient age = 50
40/50 = 0.8
periodontal condition notes options
- health
- gingivitis (localized v. generalized, mild/moderate/severe)
- periodontitis (stage and grade)
reminder
__ stage
__ grade
___ patient
one stage
one grade
one patient
it only takes one ______ to classify a patient as unstable in staging/grading
grade modifier
