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.
