Questions and Answers

What are proximal surfaces of the teeth?

  • Surfaces next to neighboring teeth in the same arch (correct)
  • Surfaces that are not visible in the arch
  • Surfaces toward the tongue
  • Surfaces that are away from the midline

    • Interproximal surfaces are visible when all of the teeth are in position in the arch.

    Study Notes

    Proximal Surfaces

    • Proximal surfaces are those adjacent to neighboring teeth within the same arch, indicating their closeness.

    Interproximal Surfaces

    • Interproximal surfaces refer to areas between adjacent teeth that are typically not visible when teeth are positioned in the arch.

    Mesial Surface

    • The mesial surface is the proximal surface of a tooth oriented toward the midline, highlighting its directionality.

    Distal Surface

    • The distal surface is the proximal surface that faces away from the midline, establishing its position relative to the center.

    Lingual Surface

    • The lingual surface is directed toward the tongue, indicating its relationship to oral anatomy.

    Labial or Facial Surface

    • The labial or facial surface refers to the area of an anterior tooth that faces the lip, with "labial" specifically denoting its connection to the lips.

    Buccal or Facial Surface

    • The buccal or facial surface pertains to the side of a posterior tooth facing the cheek, where "buccal" indicates its association with the cheeks.

    Facial Surface

    • The term facial encompasses surfaces of both anterior and posterior teeth directed toward the lips or cheeks.

    Occlusal Surfaces

    • Occlusal surfaces are broad grinding areas found on posterior teeth, essential for chewing and grinding food.

    Incisal Edge

    • The incisal edge, found on anterior teeth, is a sharp cutting edge instead of a broad surface, aiding in biting.

    Incisal Angle

    • The incisal angle is the corner formed by the intersection of a proximal surface (mesial or distal) with the incisal edge, contributing to the tooth’s shape.
