  31. 35. 1 Dental anatomy ---- Periodontium Oral mucosa Tooth Gingival unit Attachment unit 1.Free gingiva 1.Cementum. 2.Attached gingiva 2.Alveolar bone 3.Alveolar mucosa 3.Periodontal ligament
  32. 36. 1.Gingiva unit---free gingiva Free Gingiva is the gum tissue extends from the gingival margin to the base of the gingival sulcus.
  33. 37. Gingival sulcus is the space between the gingiva and the tooth. A healthy gingival sulcus will rarely exceed 3mm in depth.
  34. 38. 1.Gingiva unit---attached gingiva Attached gingiva extends from the base of this sulcus to the mucogingival junction .
  35. 39. 1.Gingiva unit---alveolar mucosa Alveolar mucosa is found apical to the mucogingival junction and is continuous with the rest of the mucous membrane of the cheeks lips and the floor of the mouth .
  36. 40. Gingival papilla is the free gingiva located in the triangular interdental space. The apex in the anterior teeth is rather sharp but is more blunt in the posterior teeth.
  37. 41. 2.Attachment unit— Cementum Alveolar bone Periodontal ligament Alveolar process is the type of bone that lines the sockets in which the roots of the teeth are held. It is thin and compact with many small openings through which blood vessels ,lymph vessals, and nerves pass. Alveolus is the socket in which the tooth rests.
  38. 42. 2.Attachment unit— Cementum Alveolar bone Periodontal ligament Periodontal ligament are the fibers attached to the alveolar bone and to the cementum

  41. 45. 1 Dental anatomy ---- tooth Periodontium Oral mucosa <ul><li>The tongue is covered with stratified squamous epithelium, scattered throughout this epithelium on the upper most surface are four types of papillae: </li></ul><ul><li>1.Vallate papillae </li></ul><ul><li>2.Fungiform papillae </li></ul><ul><li>3.Filiform papillae </li></ul><ul><li>4.Foliate papillae </li></ul>
  42. 46. 1. Vallate papillae <ul><li>A V-shaped row of circular raised papillae. </li></ul><ul><li>About 8---12 elevations in the V </li></ul><ul><li>Location—2/3 of the way back on the tongue </li></ul><ul><li>They have many tiny taste buds </li></ul>( also named Circumvallate papillae ) cells Nerve endings
  43. 47. 2.Fungiform papillae <ul><li>Location -- anterior two thirds of the tongue </li></ul><ul><li>Tiny ,round, redder, raised spot </li></ul><ul><li>They have taste buds. </li></ul>
  44. 48. 3. Filiform papillae <ul><li>Location- the remainder of the anterior two thirds of the tongue is covered with tiny pointed projections known as filiform papillae. </li></ul><ul><li>No taste function </li></ul>
  45. 49. 4.Foliate papillae <ul><li>Location-- the posterior lateral border of the tongue </li></ul><ul><li>Roughness and folds tissue. </li></ul><ul><li>Fewer taste buds </li></ul>
