│ ├── Localized (LAP)
│ └── Generalized (GAP)
└── Periodontitis as Manifestation of Systemic Disease
✏️ 1c. 2018 Reclassification - How AgP Fits Now
Simple labeled boxes showing conversion:
OLD (1999) NEW (2018 AAP/EFP)
───────────────── ─────────────────────────────
Localized AgP (LAP) → Stage III/IV + Grade C
Generalized AgP (GAP) → (Rapid progression modifier)
Chronic Periodontitis → Stage I / II / III + Grade A/B
🔷 2. COMPARISON TABLES (Most Exam-Favourite)
✏️ 2a. LAP vs. GAP - Must Draw This Table
| Feature | LAP | GAP |
|---|---|---|
| Age of onset | Circumpubertal (~puberty) | Usually <30 years |
| Teeth involved | First molars + incisors only (≤2 other teeth) | ≥3 teeth other than first molars/incisors |
| Amount of plaque | Minimal (disproportionate to destruction) | Variable - more plaque present |
| Primary pathogen | A. actinomycetemcomitans | P. gingivalis |
| Serum antibody | Robust IgG2 response | Poor antibody response |
| PMN function | Depressed chemotaxis | Less consistent |
| Familial aggregation | Strong | Less clear |
| Bone loss pattern | Vertical/arc-shaped; bilateral "mirror image" | Generalized; episodic |
| Progression | Rapid then may self-arrest | Episodic with periods of quiescence |
| Prognosis | Relatively favorable | Guarded |
✏️ 2b. AgP vs. Chronic Periodontitis - Comparison Table
| Feature | Aggressive Periodontitis | Chronic Periodontitis |
|---|---|---|
| Age | Young (<30 yrs typically) | Adults (>35 yrs) |
| Rate of progression | Rapid | Slow-moderate |
| Plaque/calculus | Minimal (disproportionate) | Commensurate with severity |
| Familial aggregation | Yes | Rare |
| Primary bacteria | A.a., P. gingivalis | P. gingivalis, T. forsythia |
| PMN defects | Common | Uncommon |

🔷 3. PATHOGENESIS FLOWCHARTS
✏️ 3a. Ecogenetic Model of AgP Pathogenesis (from Lindhe Fig. 21-10) - VERY EASY TO DRAW
GENETIC PREDISPOSITION
(Gene of major effect - Autosomal Dominant)
↓
EXPOSURE TO PATHOGEN
(A. actinomycetemcomitans, P. gingivalis)
↓
HOST UNABLE TO CONTROL INFECTION
(PMN chemotaxis defect, ↓ phagocytosis)
↙ ↘
High IgG2 response Low/Poor IgG2 response
(protective) (non-protective)
↓ ↓
LAP GAP
(localized, (generalized,
self-limiting) progressive)
MODIFYING FACTORS acting throughout:
→ Cigarette smoking (worsens GAP)
→ IgG2 antibody titers (determine LAP vs. GAP phenotype)
✏️ 3b. Role of PMN Defect in LAP Pathogenesis - Simple Flowchart
Genetic defect in PMN chemotaxis
↓
PMNs fail to migrate to periodontal pocket
↓
A. actinomycetemcomitans colonizes
first molars + incisors (first teeth to erupt)
↓
Leukotoxin destroys remaining PMNs
↓
Unchecked bacterial invasion of
connective tissue → bone resorption
↓
Strong IgG2 antibody response (in LAP)
↓
Limits spread → disease stays localized
✏️ 3c. Why Does LAP Stay Localized? - Box Diagram
Draw 4 boxes with arrows:
1. Robust IgG2 antibody response
→ opsonizes A.a. → prevents spread to other sites
2. Antagonistic bacteria colonize other sites
→ inhibit A.a. from spreading
3. A.a. loses leukotoxin-producing ability
→ disease progression arrested
4. Cementum defect hypothesis
→ hypoplastic/aplastic cementum only on
first molars + incisors → localized destruction
🔷 4. SCHEMATIC ILLUSTRATIONS

✏️ 5c. Segregation Table (from Lindhe Ch. 21)
| Inheritance Mode | Evidence |
|---|---|
