Study Notes
Introduction & Nomenclature
- Dental Anatomy studies human tooth form, structure, development, classification, and function.
- A dental arch houses the teeth within the oral cavity.
- Quadrants divide the dental arches and face into four sections: upper right, upper left, lower right, lower left.
Types & Forms of Teeth
-
Anterior teeth include incisors and canines for cutting and tearing food.
-
Incisors:
- Central incisor: first tooth towards the midline.
- Lateral incisor: second tooth towards the midline.
- Canines: third tooth towards the midline, used for tearing.
-
Incisors:
-
Posterior teeth include premolars and molars for grinding food.
- Premolars (bicuspids): used for tearing and grinding, with 2 cusps.
- Molars: large surface with multiple cusps for grinding, with 1st, 2nd, and 3rd molars.
Types of Dentitions
-
Deciduous dentition (primary or milk teeth): 20 teeth (10 in each arch, 5 per quadrant)
- Dental formula for deciduous teeth: I 2/2 C 1/1 M 2/2
- Mixed dentition: Transitional phase where deciduous and permanent teeth coexist.
-
Permanent dentition: 32 teeth (16 in each arch, 8 per quadrant)
- Dental formula for permanent teeth: I 2/2 C 1/1 P 2/2 M 3/3
- Succiduous teeth: Permanent teeth that replace deciduous teeth (incisors, canines, premolars).
- Non-succiduous teeth: Permanent molars that do not replace deciduous teeth.
Numbering & Coding Systems of Teeth
-
Palmer Notation System:
- Uses symbols to identify specific teeth within each quadrant.
- Numbers 1-8 are used for permanent teeth, A-E for deciduous teeth.
-
Federation Dentaire Internationale (FDI) System: Two-digit system:
- First digit indicates quadrant (1-4 for permanent, 5-8 for deciduous).
- Second digit indicates tooth number within the quadrant.
- Universal Numbering System: Uses numbers 1-32 for permanent, 1-20 (with "d" appended) or A-T for deciduous.
Functions of Teeth
- Mastication: Breaking down food into smaller pieces for swallowing.
- Appearance & Aesthetics: Contributes to facial beauty and a nice smile.
- Speech: Helps with pronunciation of specific words.
