Study Notes

Skull and Jaw Size in Adults

Adult skull and jaws are larger to accommodate more permanent teeth and their increased size.
Two sets of dentitions aid in this accommodation: primary (deciduous) teeth and permanent teeth.

Dentition and Tooth Memorization

Memorization of tooth names is crucial for anatomical knowledge.
Example notation for molars:
- There are 3 molars in the upper and 3 in the lower jaw on one side, represented as M 3/3.

Quadrant Division of Jaws

Jaws are divided into four quadrants for easier identification:
- Quadrant 1: Right maxillary (upper jaw)
- Quadrant 2: Left maxillary (upper jaw)
- Quadrant 3: Left mandibular (lower jaw)
- Quadrant 4: Right mandibular (lower jaw)
Quadrants for permanent dentition are numbered 1-4, while those for deciduous teeth are numbered 5-8.

Tooth Notation Systems

Palmer/Zsigmondy notation system organizes teeth using letters for deciduous teeth and numbers for permanent ones.
Established by the American Association in 1947, it assists in precise identification of dental structures.

Tooth Classification: Homodont vs. Heterodont

Homodont: All teeth are similar in shape and size, differing only in dimensions; exemplified by alligators.
Heterodont: Diverse tooth forms present in humans, adapted for various functions.
