Clinical features of gingiva

  1. 1. Clinical features of Gingiva submitted to :- submitted by :- Nadia dhiman Bds 3rd prof
  2. 2. INTRODUCTION • Gingiva is part of oral mucosa that covers the alveolar processes of jaws and surrounds the neck of the tissue . • Composed of thin outer epithelium and underlying connective tissue . • Consist of four anatomical portions – Gingival sulcus , Free gingiva, Interdental gingiva and attached gingiva .
  3. 3. • Texture of Gingiva – healthy gums have stippled ,translucent appearance. - orange peel appearance .
  4. 4. • Colour of Gingiva-coral pink -depends on the thickness and degree of keratinization of epithelium, blood flow to gingiva ,disease and medication ,natural pigmentation. • Contour of Gingiva-scalloped and knife edge margin . • Size of Gingiva-correspong with sum total of the bulk of cellular and intercellular elements and their vascular supply.
  5. 5. ANATOMIC LANDMARKS OF THE GINGIVA
  6. 6. GINGIVAL SULCUS • Its a V shaped notch . • Bounded by surface of tooth on one side and epithelium lining the free margin of gingiva on the other side. • Clinical evaluation used to determine the depth of gingival sulcus is throw metallic instrument called peridontal probe
  7. 7. • Probing or clinical probing depth is depth of penetration of probe and it is 2-3mm in normal gingival sulcus in humans . • In histological section depth is 1.8mm with variation from 0-6mm.
  8. 8. MARGINAL GINGIVA • Also called as free or unattached gingiva . • Surrounds the tooth in collarlike/cufflike manner. • Characteristic – fits closely around but not directly attached to the tooth-also form soft tissue wall of the gingival sulcus. • It is 1mm wide .
  9. 9. • Free Gingiva is demarcated from adjacent attached gingiva by shallow linear depression that follows the Contour of the tooth called ‘ marginal groove ’. •it can be separated from tooth surface by peridontal probe .
  10. 10. ATTACHED GINGIVA • Part of gingiva tightly connected to periosteum of alveolar bone . • Lies between the two movable tissue . • Colour- pale -pigmented in dark skinned individuals.
  11. 11. • Width- widest in incisor and molar region and narrowest in premolar region . • Premolar= maxilla-1.9mm mandible-1.8mm.
  12. 12. INTERDENTAL GINGIVA • It occupies the gingival embrasure . • Gingival embrasure is the interproximal space beneath the area of tooth contact .
  13. 13. •It is of two shape pyramidal and ‘’col’’ shape . •‘’col’’ is a valley like depression that connects a facial and lingual papilla .
  14. 14. • ‘’col’’ in various types of contacts . • The shape of interdental gingiva depends on the contact point between the two adjoining teeth and presence or absence of some degree of recession .
  15. 15. Interdental col in normal gingiva – mandibular anterior segment,facial and buccolingual views. Interdental col after gingival recession.
  16. 16. • In diastema,the gingiva is firmly bound over the interdental bone and the interdental papilla will be absent.
