Questions and Answers

What is the main difference between hyperplasia and hypertrophy?

Hyperplasia results in increased tissue volume due to cell proliferation, whereas hypertrophy results from increased cell size. (correct)

Hypertrophy only occurs in response to drug-induced enlargement.

Hyperplasia and hypertrophy are the same processes.

Hyperplasia involves increased cell size, while hypertrophy involves an increase in cell number.

Study Notes

Gingival Enlargement Overview

Gingival enlargement is a pathological event indicating a change in gingival tissue dimensions.
It can be transient and reversible or chronic and irreversible.
Outcomes of periodontal tissue inflammation include homeostasis, chronic periodontitis, and fibrosis.

Fibrosis Mechanism

Fibrosis serves as a defense mechanism against advancing periodontal inflammation.
Fibroblasts are crucial in producing excessive collagen and extracellular matrix proteins.
An imbalance between matrix deposition and enzymatic degradation leads to fibrosis or gingival hyperplasia.
Gingival fibrosis often corresponds with bacterial accumulation and poor oral hygiene.

Historical Context

Pathologic gingival enlargements were recognized in ancient civilizations and linked to systemic conditions by the 18th century.
The first scientific report on drug-induced gingival overgrowth (DIGO) appeared in 1939, linking diphenylhydantoinate use with gingival enlargement.
Understanding the pathogenesis of gingival enlargement is vital for improving treatment strategies.

Clinical Classification

Terminology includes gingival enlargement, gingival overgrowth, hyperplasia, hypertrophy, and fibrosis.
Hyperplasia involves an increase in cell numbers; hypertrophy involves increased cell size.
Both hyperplasia and hypertrophy often occur simultaneously, complicating differentiation.
Fibrosis is characterized by faulty healing processes affecting immune response and matrix deposition.

Types of Gingival Overgrowth (GO)

Drug-induced gingival overgrowth (DIGO) is primarily linked to three drug families:
- Anticonvulsants
- Calcium channel blockers
- Immunosuppressants
GO can also result from:
- Severe systemic diseases (e.g., leukemia)
- Genetic factors
- Idiopathic causes (not classified under known categories)
- Inflammatory changes due to gingivitis

Classification of Gingival Overgrowth

GO is classified based on etiologic factors:
- Inflammatory enlargement due to chronic gingivitis
- Drug-induced enlargement (DIGO)
- GO associated with systemic conditions
- GO associated with systemic diseases
- Gingival fibromatosis

Interaction with Underlying Structures

Enlargement may indirectly affect the dimensions of underlying osseous structures.
Understanding the link between gingival enlargement and systemic factors can aid in treatment development.
