Questions and Answers

What is the unique characteristic of mandibular central incisors compared to maxillary incisors in terms of contact points?

  • Contact points are near incisal ridges mesially and distally. (correct)
  • Contact points are at different levels on central and lateral incisors.
  • Contact points are near the gingival margins mesially and distally.
  • Contact points are located towards the lingual surfaces mesially and distally.

What happens to the mamelons on the incisal ridge of mandibular central incisors after eruption?

  • They are retained throughout life.
  • They become more pronounced with age.
  • They shift towards the lingual side.
  • They are worn off if the occlusion is normal. (correct)

What is the inclination of the incisal surfaces (edge) of mandibular central incisors?

  • Vertical inclination.
  • No specific inclination.
