periodontitis Flashcards
chronic periodontitis formerly known as….
- pyorhhea
2. adult/adult onset periodontitis
chronic periodontitis
- inflammation of gingiva and adjacent attachment apparatus
- characterized by loss of clinical attachment due to destruction of PDL and loss of adjacent supporting bone
clinical features of chronic periodontitis
- loss of attachment, probe apical to CEJ (CT fibers detach from root cementum)
- gingival inflammation (gingivitis)
- pockets– probe apical to CEJ, depths of 3-4mm
- tooth mobility
- radiographic bone loss
- bleeding, suppuration
most important factor in determining periodontitis
clinicaly measuring attachment loss
clinical patterns of chronic periodontitis
- destructive, relatively common, but less common than gingivitis, majority of cases are mild-moderate
- extent: based on teeth; 30% or less OR clear pattern is localized, over 30% is generalized
- severity based on att.loss: 1-2mm slight, 3-4mm moderate, 5+mm severe
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
- inflammatory changes
- periodontal attachment apical to CEJ (attachment loss)
aggressive periodontitis
- distinct types of periodontitis affecting otherwise healthy individuals
- usually familial aggregation
- usually rapid rate of progression
- both localized and generalized
- usually 25 years old or younger onset age
aggressivev periodontitis formerly known as
- periodontosis
- juvenile periodontitis
- early onset periodontitis
- rapidly progressive periodontitis
- severe periodontitis
- prepubertal periodontitis
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
- inflammation
- increased probings generally 5mm or more
- probing apical to CEJ, at least 4mm attc.loss
- tooth mobility
- bleeding/suppuration
- radiographic bone loss
**Same as chronic, but mmust be at least 4mm AL
clinical pattern -aggressive periodontitis
- moderate/severe loss at young age (less than 35yo)
- familial
- localized: 1st molar/incisors
- generalized
- prevalence = .5% population
**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
- might burn out
- might extend to more teeth
- localized might become generalized
- **observe unaffected siblings
- susceptibility for progression/extension might be environmental (both types found in siblings) or if genetic, suggests varying degrees of penetrance for the genes
prevalence of aggressive periodontitis - studies
2 studies of 5,000-11,000 young americans
- *less than .2% whites
- *2.1-2.6% blacks
histology of aggressive periodontitis
same as adult (chronic) periodontits
periodontitis as manifestation of systemic diseases
- hematologic disorders: leukemia, neutropenias, etc
- immune system disorders: HIV, transplant patients
- genetic disorders: cyclic neutropenia, down syndrome (cause reduced immune system)
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
- still listed in parameters of care
- was not a single disease entity
- destructive perio disease in patients who, when longitudnally monitored, demonstrate additional attachement loss at 1+ sites despite good therapy adn patient efforts to stop disease progression
NUG/NUP
NUP = NUG + attachment loss
NUG = necrotizing ulcerative gingivitis = acute infection of the gingiva which may have a combo of…
- ulceration/ necrosis of gingival margins/papilla
- necrotic gray pseudo- membrane
- severe pain
- bright red marginal gingiva
- spontaneously bleeding gums
- malodor
- possible fever adn lymphadonopathy
