Study Notes
Molars
- There are 12 molars in total, six in the upper jaw and six in the lower jaw.
- The molars are further divided into: First, Second, and Third molars.
Human Dental Formula
- The dental formula is used to express the number and type of teeth per side, in the upper and lower jaws.
Primary Teeth
- Children have 20 primary teeth, also called deciduous teeth.
- The dental formula for primary teeth is: 2/2, 1/1, 2/2, 3/3 = 10.
- Each number in the formula refers to the number of teeth per side, starting with incisors, canines, premolars, and molars, respectively.
Permanent Teeth
- Adults have 32 permanent teeth.
- The dental formula for permanent teeth is: 2/2, 1/1, 2/2, 3/3 = 16.
Palmer System (Quadrant System)
- The Palmer System divides the mouth into four quadrants.
- Teeth are numbered 1 through 8, starting from the midline.
- For deciduous teeth, letters A through E are used, starting from the central incisor.
- The system is represented as a grid with four quadrants, where each quadrant has a different symbol for upper and lower jaws.
- Letters are usually on the top and numbers are on the bottom
- This system makes it easier to identify specific teeth within the mouth.
