Study Notes
Dental Formulas
- Dogs have 28 deciduous teeth and 42 permanent teeth.
- Cats have 26 deciduous teeth and 30 permanent teeth.
Tooth Structure
- The crown is the visible portion of the tooth, while the root is embedded in the jawbone.
- Enamel is the hard outer layer of the crown, while dentin is the layer beneath it, forming the bulk of the tooth structure.
- The pulp contains nerves and blood vessels.
- Cementum covers the outer layer of the root, while the cemento-enamel junction separates the crown from the root.
- The furcation is where the multiple roots of a tooth extend from the crown.
- The apex is the tip of the root, where blood vessels and nerves enter the tooth.
Tooth Development
- Primary dentin forms before the tooth erupts.
- Secondary dentin is continuously produced after tooth eruption.
- Tertiary dentin forms when the pulp is still vital.
Dental Anatomic Review
- The document provides information about the different types of teeth and their locations in the mouth.
- The document describes how to differentiate between the teeth of different species.
- The document provides detailed information about nerve block procedures, including different types of anesthetics and their duration.
- The document details the dosage of various anaesthetics.
Deciduous Dentition in Dogs and Cats
- Dogs have 28 deciduous teeth: 2 (13/3, C1/1, P3/P3)
- Cats have 26 deciduous teeth: 2 (13/3, C1/1, P3/P2)
Permanent Dentition in Dogs and Cats
- Dogs have 42 permanent teeth: 2 (13/3, C1/1, P4/P4, M2/M3)
- Cats have 30 permanent teeth: 2 (13/13, C1/C1, P3/P2, M1/M1)
Tooth Structure
- Crown: The visible portion of the tooth.
- Root: The portion of the tooth embedded in the jawbone.
- Enamel: The hard outer layer of the crown, composed of 96% inorganic crystals.
- Dentin: The layer beneath the enamel, forming the bulk of the tooth structure, composed of 70% calcified material.
- Pulp: Innermost layer containing blood vessels and nerves.
- Cementum: Covers the outer layer of the root.
- Cemento-enamel junction: Separates the crown from the root.
- Furcation: The point where the roots of a multi-rooted tooth extend from the crown.
- Apex: The tip of the root where blood vessels and nerves enter the tooth.
Types of Dentin
- Primary Dentin: Forms before tooth eruption.
- Secondary Dentin: Forms continuously after tooth eruption.
- Tertiary Dentin: Forms as long as the pulp is vital.
Canine and Feline Tooth Types
- Incisors: Three incisors in each quadrant for both dogs and cats.
- Canines: Four canine teeth for both dogs and cats.
- Premolars: Dogs have four premolars on each side of the maxillary and mandibular arches. Cats have fewer premolars.
- Molars: Dogs have two maxillary and three mandibular molars on each side. Cats have only one molar on each side.
Dental Formulas
- Dogs have 28 deciduous teeth, using the formula: 2(I3/3, C1/1, P3/P3).
- Cats have 26 deciduous teeth, using the formula: 2(I3/3, C1/1, P3/P2).
- Dogs have 42 permanent teeth, using the formula: 2(I3/3, C1/1, P4/P4, M2/M3).
- Cats have 30 permanent teeth, using the formula: 2(I3/3, C1/1, P3/P2, M1/M1).
Adult Root Structure
- Dogs and cats have three incisors, one canine, and four premolars in each quadrant.
- Dogs have one molar on each side of their upper jaw, and two molars on each side of their lower jaw.
- Cats have one molar on each side of both the upper and lower jaw.
Tooth Structure
- The crown is the visible portion of the tooth.
- The root is the portion of the tooth embedded in the bone.
- Enamel, a hard outer layer of the crown, is 96% inorganic crystals.
- Dentin, located under the enamel, accounts for the majority of the tooth.
- Pulp contains nerve tissue and blood vessels.
- Cementum covers the root.
- The cemento-enamel junction divides the crown and root.
- The furcation is the point where multiple roots branch from the crown.
- The apex is the end of the root where nerves and blood vessels enter.
Additional Details
- Primary dentin forms before a tooth emerges.
- Secondary dentin forms after a tooth erupts and continues throughout the tooth's life.
- Tertiary dentin forms as long as the pulp retains vitality.
