Study Notes
Introduction and Nomenclature
- Dental anatomy is the study of human tooth form and structure, including development, classification, and how they contact one another in occlusion.
- A dental arch is where teeth are arranged in the oral cavity.
Tooth Types and Forms
- Anterior teeth are used for cutting and tearing food.
- Incisors: There are four incisors in each dental arch, with two in each quadrant.
- The central incisor is the first tooth to the midline.
- The lateral incisor is the second tooth to the midline.
- Canines (cuspids): There are two canines in each dental arch, with one in each quadrant. They are the third tooth to the midline and are used for cutting and tearing.
- Incisors: There are four incisors in each dental arch, with two in each quadrant.
- Posterior teeth are used for grinding food:
- Premolars (bicuspids): There are six premolars in each dental arch with three in each quadrant.
- The first premolar is the fourth tooth in the arch.
- The second premolar is the fifth tooth in the arch.
- Molars: There are four molars in each dental arch with two in each quadrant.
- The first molar is the sixth tooth in the arch.
- The second molar is the seventh tooth in the arch.
- The third molar is the eighth tooth in the arch and is also known as the wisdom tooth.
- Premolars (bicuspids): There are six premolars in each dental arch with three in each quadrant.
Types of Dentition
- Deciduous dentition (primary or milk teeth)
- Present from 6 months to 6 years of age.
- Consists of 20 teeth, 10 in each dental arch and 5 in each quadrant.
- Consists of two incisors, one canine, and two molars.
- Replaced by permanent teeth.
- "Dental formula" for deciduous dentition: I 2/2, C 1/1, M 2/2 (this represents one side of the mouth)
- Mixed dentition
- Present from 6 years to 12 years of age.
- Transition phase with both deciduous and permanent teeth present.
- Permanent dentition
- Present from 12 years of age until the end of life.
- Consists of 32 teeth, 16 in each dental arch and 8 in each quadrant.
- Consists of two incisors, one canine, two premolars, and three molars.
- "Dental formula" for permanent dentition: I 2/2, C 1/1, P 2/2, M 3/3 (this represents one side of the mouth)
Succidaneous & Non-Succidaneous Teeth
- Succidaneous teeth: Permanent teeth that replace deciduous (baby) teeth. Examples are incisors, canines, and premolars.
- Non-succidaneous teeth: Permanent teeth that do not replace deciduous teeth. Permanent molars fall into this category.
Tooth Numbering Systems
- Palmer notation system:
- Uses a cross to divide the mouth into four quadrants.
- Permanent teeth are numbered 1-8 in each quadrant, starting from the midline.
- Deciduous teeth are lettered A-E in each quadrant, starting from the midline.
- FDI (Federation Dentaire Internationale) system:
- Uses a two-digit system, where the first digit denotes the quadrant and the second digit denotes the tooth number (following the Palmer notation).
- The first digit ranges from 1-4 for permanent dentition and 5-8 for deciduous dentition.
- Universal numbering system:
- Assigns numbers 1-32 to permanent teeth, starting from the upper right third molar and moving clockwise.
- Assigns numbers 1-20 to deciduous teeth, starting from the upper right third molar.
Functions of Teeth
- Mastication: Cutting and grinding food into smaller pieces, making it easier to swallow.
- Appearance & Aesthetics: Contributing to facial beauty and a pleasing smile.
- Speech: Helping with pronunciation of certain sounds.
