Study Notes
Tooth Numbering Systems
- The Universal Numbering System assigns a different number to each tooth, starting from the maxillary right and going contralateral to the mandibular right.
Tooth Anatomy
- The lingual surface of a tooth is towards the tongue.
- The distal surface of a tooth is away from the median line.
Notation Systems
- The Quadrant Notation System uses L-shaped symbols to identify the four different quadrants.
- The Palmer Notation System designates each quadrant with a number from 1-4 and assigns each tooth in each quadrant a number from 1-8, from mesial to distal.
Molar Characteristics
- The first molar has the widest mesiodistal dimension.
- The maxillary molar has a more symmetrical shape.
- The third molar has the smallest size.
- The mandibular first molar has three roots that tend to fuse proximally.
- The maxillary second molar has a missing distal cusp, resulting in a heart-shaped tooth.
