    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.
