Why is there localisation of disease to 1st molars and incisors in LAP?
Often subjects present with attachment loss that does not fit the specific diagnostic criteria (AP or chronic periodontitis).
Schenkein et al. 1995: cigarette smoking was shown to be a risk factor for patients with generalized forms of AgP.
Smokers with GAP had more affected teeth and greater mean levels of attachment loss than patients with GAP who did not smoke.
IgG2 serum levels as well as antibody levels against A.a. are significantly depressed in subjects with GAP who smoked.

Aggressive periodontitis refers to the multifactorial, severe,
& rapidly progressive form of periodontitis, which primarily
but not exclusively affects younger patients.

In 1971, Paul Baer
characterized by a rapid loss of alveolar bone about
more than one tooth of the permanent dentition.
Baer PN. The case for periodontosis as a clinical entity. J Periodontol 1971:42: 516–520.
Baer proposed 7criteria to define the disease:-
Early onset of the disease during the circumpubertal period
(between 11 and 13 years of age)
Age of the patient per se is not a primary criterion
for the diagnosis of aggressive periodontitis
An arc-shaped loss of alveolar bone,
extending from the distal surface
of 5 to the mesial surface of the 7.
Occurs bilaterally, depicting
“mirror images” of each other
A distinctive radiographic pattern depicting
vertical alveolar bone loss at the first permanent
molars and at one or more incisor teeth.

Atypical cases of

Only the molars are affected
and not the incisors.
A rapid rate of disease progression.
Baer estimated that, typically, an affected tooth can lose 75%
of the alveolar bone support at one or more root surfaces within
5 years of disease initiation.
Atypical cases:- Alveolar bone loss progresses only to a certain
point & then may remain quiescent for many years.
The disease affects only the permanent dentition. The
primary teeth are not affected and are not prematurely
exfoliated because of destructive periodontal disease.
The amount of local etiologic factors is not commensurate with the
severity of periodontal destruction.
The disease has a familial pattern.
Predominance in female subjects. Baer reported that cases of
aggressive periodontitis have a female to male ratio of
Black male teenagers > Black female adolescent >
white female teenagers > white male adolescents.
The 1999 International Workshop for the Classification of
Periodontal Diseases and Conditions defined the entity of AP as
being characterized by “3 primary features”:-
Rapid loss of
Workshop defined several secondary features:-
1. Inconsistency of the low amounts of present etiological factors
(i.e., plaque) & the observed pronounced tissue destruction.
2. Strong colonization by Aggregatibacter actinomycetemcomitans
and, in some populations, Porphyromonas gingivalis.
3. Immunological abnormalities:-
a. Hyperresponsive macrophages
b. Abnormalities of neutrophil function
4. Self-limiting disease.
American Academy of Periodontology workshop, 1999
Localized aggressive periodontitis (LAP)
In 1989 the World Workshop in Clinical Periodontics, categorized
this disease as:- “Localized juvenile periodontitis” (LJP)
Circumpubertal onset (11 - 13 years of age).
Localized attachment loss at incisors and first molars; interproximal
attachment loss on at least 2 permanent teeth (one of which is a first
molar) and involving no more than two 0r fewer teeth other than first
molars and incisors.
Robust serum antibody response to infecting agents.
•Lack of clinical inflammation
•Amount of plaque inconsistent with the amount of
•Presence of deep periodontal pockets
•Elevated levels of A.a and P. gingivalis.
•Distolabial migration of maxillary incisors - diastema formation
•Increasing mobility of maxillary and mandibular incisors & 1st molars
•↑ Sensitivity of denuded root surfaces to thermal and tactile stimuli
• Deep, dull, radiating pain during mastication.
• Classic diagnostic sign of localized aggressive periodontitis
Vertical “arc shaped” bone loss irt molars and incisors
• Rate of bone loss is about
3-4 times faster than in
Why is there localisation of disease
to 1st molars and incisors in LAP?
Some reasons for Site specific
After initial colonization, A.a. evades the host defense
Production of PMN
Allow the bacteria to colonize the
pocket and initiate the destruction
of the periodontal tissues.
After initial attack
Immune defenses stimulated
Opsonic antibodies are produced
Phagocytosis of invading bacteria and neutralization of
leukotoxic activity. (may slow or arrest the disease process)
Bacteria antagonistic to A. a may colonize the periodontal
tissues and inhibit it from further colonization of
periodontal sites in the mouth.
3)A.a may lose its leukotoxin-producing ability for unknown
reasons which arrests or impairs the progression of the
disease & may avert the colonization of new periodontal sites.
Defect in cementum formation may be responsible for the
localization of the lesion. Root surfaces of teeth extracted
from patients with localized aggressive periodontitis have been
found to have hypoplastic / aplastic cementum.
lesser humoral response
LAP patient GAP patient
i.e, LAP and GAP would merely be phenotypic variations
of the same underlying disease.
This assumption is backed by several reports that
show a sequence of LAP and GAP in the same individuals
Initially it was thought that LAP gradually becomes
GAP over time. But some cases of LAP don’t show any
increased bone destruction; are known to arrest
spontaneously, leading to ceasation of disease activity.
Proposed by Ranney.
Encompasses the diseases that were previously classified as generalized
juvenile periodontitis and rapidly progressive periodontitis.
Generalized aggressive periodontitis
Usually affect <30 years of age, but patients may be older.
Generalized interproximal attachment loss affecting at
least three permanent teeth other than first molars and
Pronounced episodic nature of the destruction of
attachment and alveolar bone.
Poor serum antibody response to infecting agents.
Clinical features of GAP
2 gingival tissue responses:
Severe, acutely inflamed tissue that is often
proliferating, ulcerated, and fiery red-
# Active loss of attachment & bone
Tissues appear pink, free of inflammation, &
occasionally with some degree of stippling –
# Deep pockets
# Bone & attachment levels relatively
stable(Period of Quiscence)
Severe bone loss associated with the minimal number of teeth to
advanced bone loss affecting the majority of teeth in the
• Often subjects present with attachment loss that does not fit
the specific diagnostic criteria (AP or chronic periodontitis).
Recessions associated with trauma or tooth position,
Attachment loss associated with impacted third molars,
removal of impacted third molars,etc.
These patients are a high-risk group for AP or chronic
Incidental attachment loss
RISK FACTORS FOR AGGRESSIVE PERIODONTITIS
a) Microbiologic Factors
2. Capnocytophaga sp
3. E. corrodens
4. P. intermedia
5. Motile anaerobic rods,
such as C. rectus
6. Gram-positive isolates
1. Porphyromonas gingivalis,
3. Bacteroides forsythus
A. a has been implicated as the primary pathogen associated with LAP. As
summarized by Tonetti and Mombelli, it is based on the following
1. A.a is found in high frequency (approx. 90%) in lesions characteristic of LAP.
2. Sites with evidence of disease progression often show elevated levels of A.a
3. Many patients with the clinical manifestations of LAP have significantly elevated
serum antibody titers to A.a.
4. Clinical studies show a correlation between reduction in the subgingival load of A.a
during treatment and a successful clinical response.
5. A.a. produces a number of virulence factors that may contribute to the disease
RISK FACTORS FOR AGGRESSIVE PERIODONTITIS
b) Immunologic Factors
Human leukocyte antigens (HLAs) have been evaluated as candidate
markers for aggressive periodontitis. HLA A9 & B15 antigens are
consistently associated with aggressive periodontitis
Functional defects of PMNs, monocytes, or both :-
Impair the chemotactic attraction of PMNs to the site of
infection or their ability to phagocytose & kill microorganisms.
Hyperresponsiveness of monocytes from LAP patients involving
their production of prostaglandin E2 in response to LPS
Increased connective tissue or bone loss
RISK FACTORS FOR AGGRESSIVE PERIODONTITIS
c) Genetic Factors
Segregation analyses -- autosomal dominant mode of inheritance
(Saxen & Nevanlinna 1984, Beaty et al. 1987, Hart et al. 1992, Marazita
et al. 1994).
Antibody response to periodontal pathogens, particularly A.a, is
under genetic control, and that the ability to mount high titers of
specific, protective antibody (primarily IgG2) against A. a may be
RISK FACTORS FOR AGGRESSIVE PERIODONTITIS
d) Environmental factors
• Schenkein et al. 1995: cigarette smoking was shown to be a risk factor
for patients with generalized forms of AgP.
• Smokers with GAP had more affected teeth and greater mean levels
of attachment loss than patients with GAP who did not smoke.
• IgG2 serum levels as well as antibody levels against A.a. are
significantly depressed in subjects with GAP who smoked.
Antimicrobial Therapy; Local Delivery
Conventional Periodontal Therapy
• Surgical Resective Therapy
• Regenerative Therapy
MANAGEMENT OF AGGRESSIVE PERIODONTITIS
Its effect on aggressive periodontitis is much less clear.
For LAP, the effect of scaling and root planing alone represent the first
phase of a staged combination therapy.
Slots & Rosling
Unsal et al
GAP responds well to scaling & root planing in the short term (upto 6 mths).
However, after 6 months, relapse and disease progression is reported.
Gunsolley et al.
Haas et al,2008
Sigusch et al,1998
SRP reduced the total sub-gingival bacterial counts and the proportions
of certain gram-negative bacteria, but no periodontal pocket became
free of A. actinomycetemcomitans.
Systemic tetracycline (250 mg of tetracycline hydrochloride 4x/day
for at least 1 week) in conjunction with local mechanical therapy.
If surgery is indicated, systemic tetracycline 1000mg stat should be
prescribed approximately 1 hour before surgery.
Tetracycline resistant A.a:- Amoxicillin-Metronidazole;
Doxycycline, 100 mg/day, may be used instead of
Chlorhexidine rinses should be prescribed and
continued for several weeks to enhance plaque
control and facilitate healing.
Genco et al treated LAP patients with:-
SRP Systemic administration of tetracycline
(250 mg q.i.d x 14 days every 8 weeks).
Bone loss stopped, 1/3rd of defects demonstrated an increase in bone level
Liljenberg and Lindhe treated LAP patients with
Systemic administration of tetracycline (250 mg q.i.d for 2 weeks)
Modified Widman flap
Periodic recall visits (one visit every month for 6 mths, then one visit every 3 mths).
The lesions healed more rapidly and more completely
In practice, antibiotics are often used empirically without microbial
Empiric use of antibiotics, such as a combination of amoxicillin &
metronidazole, may be more clinically sound and cost-effective
than bacterial identification & antibiotic-sensitivity testing.
Associated Microflora Antibiotic of Choice
Gram-positive organisms Amoxicillin–Clavulanate potassium
Gram-negative organisms Clindamycin
P. gingivalis Azithromycin
Antibiotic Therapy for Aggressive Periodontitis
Generalized Aggressive Periodontitis:
Sigusch et al (2001), Xajigeorgiou et al (2006), Guerrero et al (2007)
suggested use of Clindamycin + SRP showed increase in clinical
attachment gain and reduction in pocket depth
Kaner et al (2007) showed use of metronidazole/ amoxicillin given
immediately after SRP will be more effective in resolving deep sites in
Local delivery agents including solutions, gels, fibers, chips
Smaller dosages of topical agents can be delivered inside the pocket,

Increases the exposure of the target microorganisms to higher
concentrations, of the medication.
- Another approach to antimicrobial therapy.
- The concept, described by Quirynen et al, consists of:-
Full-mouth debridement completed in 2 appointments within a 24-hour period
The tongue is brushed with a chlorhexidine gel (1%) for 1 minute,
Mouth rinsed with a chlorhexidine solution (0.2%) for 2 minutes,
Periodontal pockets irrigated with a chlorhexidine solution (1%)
Significant reductions in periodontal pathogens up to 8 months
after therapy. P. gingivalis and T. forsythia were reduced to levels

therapeutic efforts, frequent visits and good patient compliance,
microbial testing may be indicated.

Baer believed that the variations in the clinical features of aggressive periodontitis are
caused by the variability in the phase of disease development and whether the disease is diagnosed at an early phase or an advanced phase.
