  43. What is dentin ?
    it is the hard tissue that makes the body of the tooth. It protects the pulp and is covered by enamel at the anatomical crown and then covered by cementum at the anatomical root.

    Dentin makes up the majority of the tooth.

    The area that the enamel meets the cementum of the tooth.
  45. What is the Dentino-enamel Junction ?
    it is the portion of the tooth where the enamel meets the Dentin. This would be in the anatmical crown of the tooth.
  46. What is Pulp ?
    The living tissue that occupies the pulp cavity of the tooth.It contains the nutrient supply that comes from blood vessels. It also has the nerve supply.
  47. What is the pulp cavity?

    It is the portion of the pulp cavity where the cusps or lobes are created.
  51. What is the Alveolar process ?
    The bony area that supports the tooth in each jaw.

    The portion of the Alveolar process where the tooth is set.
  53. Periodontal Ligament (Membrane) ?
    the area in which the tooth is anchored into the the alveolar bone by the cementum.
  54. Gingiva (Plural Gingivae) ?
    The Gums or Gum , this portion surrounds the alveolar process , the neck of the teeth and is covered by a mucous membrane.
  55. What are considered he anterior teeth ?
    The Incisors and Canines.
  56. What are considered the Posterior Teeth?
    Molars and Premolars
