Juvenile Periodontitis Flashcards
Old name?
Periodontosis… N remember, Desquamative gingivitis used to be called Gingivosis
Clinical feat-
1 Cementopathia…
2. Diffuse atrophy of alveolar bone…
1st clinical feature of LJP?
- Pathologic migration
Age of onset of JP or rapidly progressive periodontitis?
10-19 yrs
Age of onset of prepubertal periodontisis?
Below 11 yrs
LJP predilection in?
Females!!
Mirror image (Bilaterally symmetrical) type of bone loss seen in?
LJP
Etio for LJP?
Actinomycetemcommitans… If Actino… not given in options… Select PREVOTELLA..
Cause of generalized juvenile periodontitis?
P. Gingivalis
Pathogenesis-??
- Defective chemotaxis of NEUTROPHILS…
- HLA A9 n B15 increased
- Hyperresponsiveness of MONOCYTES ————-= PG E2 increased… ————-= Bone loss…
- Poorly functional inherited form of FC Gamma R 2 ————-= Receptor to IG A2
Prepubertal Periodontitis is associated with?
- Papillon levefre synd
- Chediac hegashi synd
- Down’s synd
- Neutropenia
- Hypophosphatasia
- Leukemia
CLINICAL QUESTION -
SPARSE CALCULUS n PLAQUE, MIGRATION OF CI leading to diastema, MOBILITY OF INCISORS and MOLARS… ARC shaped ALVEOLAR BONE LOSS from distal of 2nd Pm to mesial of 2nd Molar…
Deep dull radiating pain..(not important)
Dx - Localized aggressive periodontitis…
Host modulation therapy for this?
Subantimicrobial dose of DOXYCYCLINE…
CLINICAL QUESTION -
3 yr old… Severe HORIZONTAL Bone loss… With NORMAL Cementum… Dx??
PRECOCIOUS PERIODONTITIS AKA Papillon Levefre Synd
Why not LJP?
Because the BONE LOSS is HORIZONTAL (not VERTICAL… which is seen in LJP)… CEMENTUM is NORMAL… (There is CEMENTOPATHIA in LJP)
CLINICAL QUESTION -
AGGRESSIVE PERIODONTITIS is characterized by all EXCEPT?
All — NON Inflammatory
— Non contributory medical history
— rapid attachment loss
— familial aggregation of cases
— PATHOLOGICAL MIGRATION which is not correct according to the question…
Check, because it looks so controversial…
Not true about JP?
Inflammatory process starts simultaneously as bone loss… (Not true)
