Macroscopic feature of gingiva according to caranza

1. GINGIVA By Pranjali Nalawade IIIrd year BDS Macroscopic features of

2. Definition : Gingiva is that part of oral mucosa which covers the alveolar processes of the jaws and surrounds the necks of teeth. -Carranza

3. Parts of Gingiva MARGINAL GINGIVA INTERDENTAL GINGIVA ATTACHED GINGIVA GINGIVAL SULCUS

4. Macroscopic features

5. Colour Normally coral pink in color. produced by -Vascular supply -Thickness & degree of keratinization of epithelium -Presence of pigment containing cells. Alveolar mucosa – red, smooth & shiny

6. Physiologic pigmentation (Melanin) deep purplish discoloration or as irregularly shaped brown and light brown patches may appear as early as 3 hours after birth.

7. Contour Normal contour : (a) scalloped and knife-edged , (b) whereas the interdental papilla, anterior region  pyramidal posteriorly  tent-shaped Factors responsible: Shape of teeth and their alignment Location and size of proximal contact Dimensions of facial and lingual embrasures

8. Consistency The gingiva is firm & resilient , with the attached part tightly anchored to the teeth and underlying alveolar bone. The gingival fibers contribute to the firmness of the gingival margin. Checked by palpation using a blunt instrument or digital pressure .

9. Surface texture Stippling is generally present to varying degrees on vestibular surfaces of the attached gingiva. “orange peel” appearance  stippling Best viewed by drying the gingiva. seen in- Attached gingiva & central portion of interdental gingiva; It is a feature of healthy gingiva.

10. Size Depends on- sum of bulk of cellular and intracellular elements, and their vascular supply. Normal In disease- increased  ‘gingival enlargement.’

11. Position The normal position: 1mm above CEJ Factors that maintain Position of the teeth in the arch. Root-bone angle Mesio-distal curvature of tooth surface.
