Study Notes

Dental Terminology

Dental Notation uses a system for identifying teeth, including Palmer Notation, FDI Primary, and FDI Permanent.
Palmer Notation uses a combination of letters and numbers to identify teeth, with a separate notation for primary and permanent dentitions.
FDI (Federation Dentaire Internationale) uses a two-digit system to identify teeth, with the first digit representing the quadrant and the second digit representing the specific tooth within that quadrant.
Dentitions refer to the different sets of teeth that humans develop throughout their lives.
Primary dentition, also known as "baby teeth," consists of 20 teeth that emerge between the ages of 6 months and 3 years.
Permanent dentition, also known as "adult teeth," consists of 32 teeth that replace the primary teeth and erupt between the ages of 6 and 21.
Tooth morphology refers to the shape, size, and structure of teeth.
Tooth morphology is essential for understanding how teeth develop and function.
The incisal edge of a tooth is the biting surface of anterior teeth.
Cusps are the pointed projections on the occlusal surface of teeth, which are used for chewing.
Enamel is the outer surface of the anatomical crown, and is the hardest substance in the body, composed of 96% inorganic material.
Dentin forms the bulk of the tooth beneath the enamel and is harder than bone, but less hard than enamel.
Cementum covers the root of a tooth and acts as a protective layer.
Pulp is the soft tissue found inside the tooth, containing blood vessels and nerves.
Periodontal ligament is a fibrous tissue that connects the cementum to the alveolar bone.
Alveolar bone is the bone that surrounds and supports the teeth.
Gingiva (gums) is the soft tissue that covers the alveolar bone and surrounds the necks of the teeth.
Functions of Teeth include:
- Incisors are designed for cutting and biting food.
- Canines are designed for tearing and piercing food.
- Premolars are designed for crushing and grinding food.
- Molars are designed for grinding and chewing food.
- Teeth also play an important role in speech.
Tooth identification involves determining the type of tooth, whether it is primary or permanent, its location within the mouth, and its specific name (e.g., central incisor, first molar).

Basic Tooth Structure

The anatomical crown is the visible portion of the tooth above the gumline.
The clinical crown is the portion of the tooth that is visible above the gumline at a given point in time, and can vary depending on the position of the gumline.
The root is the portion of the tooth embedded within the alveolar bone.
The neck is the constricted area that connects the anatomical crown to the root.
Enamel, which is the hardest substance in the body, forms the outermost layer of the crown.
Dentin, which is harder than bone, forms the majority of the tooth beneath enamel.
Cementum is a thin layer that covers the root of the tooth, providing protection and attachment for the periodontal ligament.
The pulp cavity is the space within the tooth that contains the soft tissue called pulp.
Pulp contains blood vessels, nerves, and connective tissue that nourish the tooth, and helps to detect pain and temperature changes.

Primary Dentition

Primary dentition, often referred to as "baby teeth", consists of 20 teeth that are replaced by permanent teeth.
The eruption of primary teeth usually begins around 6 months of age and is typically completed by 3 years of age.

Permanent Dentition

Permanent dentition, also known as “adult teeth", consists of 32 teeth that replace the primary teeth.
The eruption of permanent teeth begins around 6 years of age and is typically completed by 21 years of age.
The permanent dentition is characterized by having 8 incisors, 4 canines, 8 premolars, and 12 molars.

Teeth Configuration in Each Quadrant

Each quadrant of the mouth contains a specific set of teeth.
The upper right quadrant contains an incisor, canine, two premolars, and three molars.
The upper left quadrant contains an incisor, canine, two premolars, and three molars.
The lower right quadrant contains an incisor, canine, two premolars, and three molars.
The lower left quadrant contains an incisor, canine, two premolars, and three molars.
