Study Notes
Upper Molars Characteristics
- The palatal root of upper molars is typically conical in shape.
- The roots of upper seventh molars (upper 7) are inclined buccally, which means they lean towards the cheek side.
Cusp Development in Upper Molars
- The cusp that is likely to be rudimentary in upper molars is the distolingual cusp, often underdeveloped compared to others.
Third Molars Features
- Supplemental grooves on third molars contribute to a wrinkled or irregular appearance on their occlusal surfaces.
Upper Sixth Molar Occlusal Surface
- Upper sixth molars (upper 6) usually feature four fossae on their occlusal surface: central, mesial, distal, and a small developmental fossa.
Identification of Upper First Molar
- A key feature for identifying the upper first molar is its distinctive shape and the presence of the prominent mesiobuccal cusp, which is significantly larger than adjacent cusps.
