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.
