6. DEFINITION :
“Periodontitis is defined as an inflmmatory disease of
the supporting tiisue of the teeth caused by specific
micro organisms,resulting in progressive destruction of
PDL and alveolar bone with increased probing depth
formation,recesion or both”

7. Aggressive periodontitis describes a type
of periodontal disease and includes two of the seven
classifications of periodontitis:
Localized aggressive periodontitis (LAP)
Generalized aggressive periodontitis (GAP)

9. LOCALIZED AGGRESSIVE PERIODONTITIS
•Onset at about puberty
•Affects primarily molars and incisor teeth
•Deep pockets and advanced bone loss

12. Etiology is unknown BUT connection
between the disease & presence of
of anaerobic gram negative bacteria

13. Clinical characteristics :
Localized first molar / molars
presentation with interproximal
attachment loss on atleast two
permanent teeth,one of which is a first
molar , and involving no more than two
teeth other than first molar and
incisors”

14. •LAP lack of clinical inflammation despite the
presence of deep periodontal pockets and advanced
bone
•Amount of plaque on affected teeth is minimal
•Distolabial migration of maxillary incisors with
concomitant diastema formation
•Increasing mobility of the maxillary and mandibular
incisors and first molars
•Senstivity of denuded root surfaces to thermal and
tactile stimuli
•Deep ,dull,radiating pain during mastication causedby
irritation of supporting srructures by mobile teeth and
impacted food

16. RADIOGRAPHIC FINDINGS :
•Vertical loss of alveolar bone around the first
molars and incisors
•Begiining at puberty in otherwise healthy
teenagers is a daignostic sign
•Arc shaped loss of alveolar bone extending
from distal surface of the premolar to the mesial
surface of the second molar

20.  characterised by “ generalized interproximal
attachment loss affecting atleast three permanent
teeth than first molars and incisors”
•Destruction appears with periods of advanced
followed by quiescence of varaible length
GAP often have small amount of plaque
associated with the affected teeth
P.gingivalis,A.actinomycetemocomitans and tannerella
forsythia are detected in plaque

22. 1)Severe ,acutely inflammed ,proliferating,ulcerated and fiery red
Bleeding may occur spontaneously
• Suppuration may be an important features
2)Gingival tissues may appear pink, free of inflammation
Some stippling may be present
Deep pocket can be demostrated by probing

23. •Patients with GAP may have systemetic manifestation
•Like weight loss,general malasie n mental depression
•As seen with LAP may be arrested spontaneously or after
therapy,where as others may continue to progress to tooth
loss.

24. Radiographic findings
•severe boneloss associated with
minimal number of teeth
•Advanced bone loss affecting the
majority of teeth in the dentition

25. PREVELENCE :
• Black were at much higher risk than white s
for all forms of aggressive periodontitis
•Male teenagers were more likely to
have GAP than female adolescents

26. Risk factors for aggressive
periodontitis
•Microbiologic factors
•Immunologic factors
•Genetic factors
•Environment factors
