chronic periodontitis formerly known as….
2. adult/adult onset periodontitis
chronic periodontitis
- characterized by loss of clinical attachment due to destruction of PDL and loss of adjacent supporting bone
clinical features of chronic periodontitis
most important factor in determining periodontitis
clinicaly measuring attachment loss
clinical patterns of chronic periodontitis
determining severity based on clinical att loss, probing depths, radiographic bone loss
slight: 1-2mm, probe 3-5mm, 2-3mm radiographic loss (less than 15% root length)
moderate: 3-4mm, 5-7mm probe, 16-30% root length or 3-5mm loss radiographically
severe: 5+mm, over 7mm probing, radiographic loss is 5+mm or over 30% root length
ALL BLEED ON PROBING
what does severe chronic periodontitis often have?
-class II or III mobility, class 2 or 3 furcation vertical bony defects
chronic periodontitis - histo changes
- periodontal attachment apical to CEJ (attachment loss)
aggressive periodontitis
aggressivev periodontitis formerly known as
age of onset: aggressive vs chronic
aggressive is usually younger than 25
chronic is 50s, 60s, maybe just starting in 40s
clinical features of aggressive periodontitis
**Same as chronic, but mmust be at least 4mm AL
clinical pattern -aggressive periodontitis
**less than .2% white population, 2.1-2.6% black population (in USA)
specific pattern of aggressive localized periodontitis
1st molars adn incisors (localized)
**generalized is at least 3 more teeth in addition to 1st molars and incisors
**can call it aggressive if only on 1 1st molar (as long as its not from another factor)
localized vs generalized, whites vs balck
blacks - more localized
whites - more generalized
progression of aggressive periodontitis
prevalence of aggressive periodontitis - studies
2 studies of 5,000-11,000 young americans
histology of aggressive periodontitis
same as adult (chronic) periodontits
periodontitis as manifestation of systemic diseases
NOT METABOLIC DISEASES (diabetes, hormonal – you can have periodontitis as a complication of diabetes, but no ‘diabetes assoc. periodontitis’ like in gingivitis)
refractory periodontitis
NO LONGER USED
NUG/NUP
NUP = NUG + attachment loss
NUG = necrotizing ulcerative gingivitis = acute infection of the gingiva which may have a combo of…
difference in NUG and NUP
in NUP, you lose attachment
***these are the ones they check for on college campuses around exam time – smoking, stress, lack of sleep
NUG and NUP
treat with light scaling and chlorhexadine
rare and usually only in HIV+
localized or generalized
clinical patterns of NUG/NUP (soft tissue destruction/necrosis of papillary and possibly marginal gingiva)
USUALLY HIV+
