Questions and Answers

What occurs during the Adaptation Stage of gingival healing?

The epithelium on the flap begins proliferating. (correct)

Collagen fibers form and attach to the tooth surface.

New cementum forms at the root's apical portion.

Connective tissue from the flap's subsurface invades the fibrin layer.

In the Proliferation Stage, what is the primary change happening?

Formation of new cementum at the root.

Connective tissue growth occurs only from one surface. (correct)

Thick collagen fibers form between tissues.

Collagen fibers mature and insert into the cementum.

What characterizes the Maturation Stage of gingival healing?

The epithelium proliferates toward the root surface.

Fibroblasts appear adjacent to the root surface.

Formation of collagen fibers inserts into the cementum layer. (correct)

Fibrin layer is present between the flap and the root.

Study Notes

Healing of Gingival Defects

Adaptation Stage (0-4 days):
- Repositioned flap separated from root surface by fibrin layer
- Epithelium on flap starts growing towards the tooth surface at the crown
Proliferation Stage (4-21 days):
- Fibrin layer invaded by connective tissue from flap
- Connective tissue growth occurs from one side
- Fibroblasts appear near root surface after 6-10 days
- Thin collagen fibers form near the root surface, but a fibrous union isn't present
- Epithelium continues to grow towards root surface
Attachment Stage (27-28 days):
- Collagen fibers are formed
- New cementum layer forms at the root's apical portion in the recession
Maturation Stage (2-3 months):
- Ongoing collagen fiber formation
- Collagen fibers attach to the cementum layer of the cleaned root surface in the recession's apical portion
Free Gingival Autografts
- Used to increase width of attached gingiva or cover exposed roots
- Made of epithelium and a thin layer of connective tissue
