Study Notes
Dental Anatomy - Dental Formula & Notation Systems
- Dental formula represents the number and type of teeth in mammals, used to differentiate from other species.
- The formula shows one side of the jaw; both sides have the same number of teeth in humans.
- Each letter of the formula is followed by a horizontal line.
- Number of each type of tooth is placed above the line (maxilla - upper jaw) and below the line (mandible - lower jaw).
Teeth Notation
- Teeth are often represented by the initial letter in their name (I for incisors, C for canines, P for premolars, M for molars).
Permanent Dentition
- The permanent set of human teeth includes 32 teeth.
- The formula is: 2I, 1C, 2P, 3M x 2 = 32
Primary/Deciduous Dentition
- Primary dentition consists of 20 teeth.
- The formula is: 2I, 1C, 2P, 3M x 2 = 20
Mammalian Formulas (examples)
- Man & Monkey: 2 1 2 3 = 32
- Rabbit: 2 0 3 3
- Cow/Goat: 0 0 3 3
- Dog: 3 1 4 2
- Rat/Mouse: 1 0 0 3
- Elephant: 1 0 0 3
- Kangaroo: 3 1 4 4
- Sheep: 3 1 3 3
Eruption Patterns
- Deciduous and permanent dentitions follow a general order of eruption.
- Mandibular deciduous teeth typically erupt before their maxillary counterparts.
- Canines usually erupt after the first molars in each quadrant.
Primary Dentition Eruption Pattern (example)
- Mandibular central incisor (1) erupts around 6 months old.
Tooth Numbering Systems
- Universal/American Notation: Uses consecutive numbers (1-32) for permanent teeth, and numbers with a 'd' suffix (1d-20d) for deciduous teeth.
- Zsigmondy/Palmer Notation: A symbolic system for permanent and deciduous teeth, used in naming the teeth. It was developed by Adolph Zsigmondy of Vienna (permanent teeth) and then amended to cover deciduous teeth in 1874.
- FDI Notation: A two-digit system for both primary and permanent dentition, employed by the World Health Organization among others.
Tooth Quadrants
- Teeth are often divided into four quadrants (Maxillary Right, Maxillary Left, Mandibular Right, Mandibular Left).
- The notation systems use this division to locate teeth precisely.
