Name the parts
-Trachea -Soft palate -Epiglottis
-Hard palate -Esophagus -Tonsil
-Nasal cavity -Larynx
What is the Maxillary bone?
Pertaining to the upper arch, this consists of many bones
Incisive bone
Rostral maxilla. Supports incisor teeth.
Defects information = cleft palate
Mandible bone
Lower jaw
There are two: the left and right mandible
Mandibibular Symphysis bone
The point at which the mandibular processes fuse, forming the mandible
Terms of Oral Direction
1. Labial:
2. Buccal:
3. Palatal:
4. Lingual:
- The surface of the tooth adjacent to the lips.
- The surface of the tooth adjacent to the cheeks.
- The surface of the tooth adjacent to the palate or roof of the mouth.
- The surface of the tooth adjacent to the tongue.
Terms of Oral Direction
1. Mesial:
2. Distal:
3. Occlusal:
- The surface of the tooth closest to the median line of the head.
- The surface of the tooth farthest away from the median line of the head.
- Surface of binding/grinding

Tooth anatomy
-Enamel -Root -Pulp
-Periodontal ligament -Crown
-Dentin -Cementum -Alveolar bone
What is the enamel?
Hard outer layer of the tooth crown.
What is Pulp?
What is it composed of? (5)
- Soft tissue within the tooth
- Composed of: odontoblasts, nerves, blood vessels, lymphatics, and connective tissue.
Enamel is the ___ tissue in the body and its formation is completed before the tooth has ____.
It is what covers the ___ of the tooth and helps ____ the tooth from bacteria and acids.
Enamel, unlike bone, is not ___ and if damaged it will not ___.
- Hardest
- Erupted
- Crown
- Protect
- Living
- Regrow
Pulp is the ___ tissue portion of the tooth which includes the ___, ___ vessels, and ___ tissue.
It is called the “___ ___” when it is located in the crown of the tooth, and the “___ ___” when is located in the root of the tooth.
- Soft
- Nerves, Blood vessels, & Soft tissue
- Pulp chamber
- Root canal
Cementum is the ___ tissue that covers the ___ and is attached to the alveolar bone by the periodontal ligament.
It is ___ deposited throughout the pet’s lifetime.
It can be lost due to physiological or pathological means (called ___) and is capable of repair (called ___).
- Bony
- Root
- Continuously
- Resorptive
- Reparative
Periodontal ligament is the tissue that attaches to the root ___ on one side of the tooth and the alveolar bone on the other side of the tooth.
It allows the tooth to have slight ___ and acts as a “___” absorber for the tooth.
- Cementum
- Movement
- “Shock”
What is the periodontal ligament?
What is the gingiva?
- Connective tissue connecting the tooth to the alveolar bone.
- Connective tissue cuff around each tooth (gums).
What is the alveolar bone?
Bone forming the sockets for the teeth.
What is gingival sulcus?
The normal space between the free gingiva and the tooth.
Name the stages of tooth development.
- Initiation/Lamina stage
- Bud stage
- Cap stage
- Bell stage
- Eruption
Odontogenesis definition
Tooth development
Primary vs Permanent teeth
- Primary (deciduous):
Dogs and cats are diphyodont having two sets of teeth in their lifetime. - Permanent:
These push the primary teeth out during normal eruption. If this doesn’t occur, problems will happen, and primary teeth should be removed.
What is dentin?
Hard connective tissue forming the main bulk of most teeth
What is cementum?
Bone-like connective tissue usually covering the surface of tooth roots.
What is the apical delta?
The canal openings at the apex of the root that allows access of the nerves & blood vessels.
What happens in each stage of tooth development? (4)
- Initiation/Lamina stage:
- The interaction between mesenchymal tissue and ectodermal tissue. - Bud stage:
- The dental lamina will proliferate into the mesenchyme to form buds which teeth will develop from. - Cap stage:
- There are 3 structures that develop: 1 the enamel organ, 2 the dental papilla, and 3 the dental sec. Collectively known as “tooth germ.” - Bell stage:
- This is when the enamel organ is differentiated. This is then followed by the dental sac development, which develops the gingival tissue, alveolus, periodontal ligament and cementum.
