Study Notes
Introduction to Dental Anatomy
- Dental anatomy studies human tooth morphology, development, classification, and function.
- The study of dental occlusion involves the relationship between teeth when they come together.
- A dental arch is the region within the oral cavity where teeth are arranged.
Nomenclature and Types of Teeth
- The dentition is divided into quadrants based on the midline of the face and arches.
- There are four types of teeth: incisors, canines, premolars, and molars.
- Incisors function in cutting and tearing food, while canines are crucial for cutting and incising.
- Premolars and molars function in grinding food.
Types of Dentitions
- There are three types of dentitions: deciduous, mixed, and permanent.
- The deciduous dentition (milk teeth, primary teeth) is present from 6 months to 6 years.
- The mixed dentition period occurs between 6 and 12 years, during which deciduous teeth are replaced with permanent teeth.
- The permanent dentition is the final set of teeth and remains for life.
Dental Formulas
- Dental formulas represent the number of each type of tooth in one quadrant.
- The deciduous dentition formula is: I 2/2, C 1/1, M 2/2.
- The permanent dentition formula: I 2/2, C 1/1, P 2/2, M 3/3.
Succidaneous and Nonsuccidaneous Teeth
- Succidaneous teeth replace deciduous teeth, such as incisors, canines, and premolars.
- Non-succidaneous teeth have no deciduous predecessors, such as permanent molars.
- All permanent molars are non-succidaneous teeth.
Numbering and Coding Systems
- The Palmer Notation system allows for easy identification of teeth in each quadrant.
- Permanent teeth are numbered 1-8 in each quadrant, while deciduous teeth are lettered A-E.
- The Federation Dentaire Internationale (FDI) uses a two-digit system to identify teeth, with the first digit representing the quadrant and the second digit representing the tooth number.
- The universal numbering system (UNS) assigns numbers 1-32 to permanent teeth and 1-20 (or A-T) to deciduous teeth.
Functions of Teeth
- Mastication: The primary function of teeth is to cut and grind food into smaller pieces for easier swallowing.
- Appearance and Aesthetics: Teeth contribute to facial aesthetics and a person's smile.
- Speech: Teeth are essential for speech, helping in proper pronunciation.
