Questions and Answers

What is attrition?

  • The normal functional aging process of teeth
  • The transmission of forces generated during occlusion and mastication
  • The loss of tooth structure caused by tooth-to-tooth contact (correct)
  • The loss of tooth structure in the cervical neck area of the teeth

    • What are the areas most affected by attrition?

  • Arch length
  • Cervical neck area of the teeth
  • Occlusal surfaces of the posterior teeth and incisal edges of the anterior teeth (correct)
  • Interproximal contact points of the teeth

    • How can attrition be recognized?

  • Flattening of the normal rounded contour and polished appearance (correct)
  • Transmission of forces generated during occlusion and mastication
  • Wedge-shaped areas of enamel loss
