Study Notes
- Teeth in the human mouth include incisors, canines, premolars, and molars.
- Incisors are the first and lateral teeth from the midline in each quadrant and function in biting, cutting, and incising.
- Canines are the third tooth from the midline in each quadrant and function in cutting, tearing, piercing, and holding.
- Premolars are the two teeth closest to the midline in each quadrant and have functions in mastication, including tearing, holding, and grinding. They are present only in permanent teeth.
- The dental formula for human teeth includes I (incisors) C (canines) P (premolars), and M (molars) for both deciduous and permanent teeth.
- Human dentition goes through three stages: primary dentition (from 6 months to 6 years), mixed dentition (between 6 and 12 years), and secondary dentition (after 12 years).
- Permanent teeth can be classified as succedaneous (teeth that replace deciduous teeth) or non-succedaneous (teeth without predecessors).
- Teeth can be grouped into anterior (incisors and canines) and posterior (premolars and molars) categories.
- The numbering system for teeth includes the Universal Numbering System (using letters and numbers) and the Palmer Notation System (using letters only).
- The Federation Dentaire International (FDI) system uses a two-digit numbering system.
- Teeth serve various functions, including mastication, appearance, speech, growth of jaws, and forensic odontology.
- Each tooth has five surfaces: facial, labial, lingual, palatal, and proximal.
- Incisors have a mastication (occlusal) and incisal surface, while posterior teeth have an occlusal surface.
