Name the animals that have brachydont teeth:
Horses, cows, herbivores
Name the animals that have hypsodont teeth:
Brachydont
These types of teeth have short crowns, well developed roots, and only narrow canals in the roots
Hypsodont
These types of teeth have high crowns that erupt throughout life providing extra material for grinding food particulates down

Select and name the 4 components that make up the periodontium:
Enamel
What is the hardest substance in the body?
enamel
This is the hard, white substance that covers the tooth crown. Formed by ameloblasts in root bud (but amelogenesis stops prior to tooth eruption) aka incapable of repair after eruption. Effective barrier to heat/cold/sweet sensitivity
enamel
Which is NOT able to repair after eruption?: dentin or enamel
Dentin
This makes up the BULK of the tooth, comprised of tubules that communicate between pulp, enamel, and cement junctions. Contain odontoblasts that produce this throughout the life of the tooth when the tubule is exposed
Primary (dentin when tooth is being formed), secondary (after tooth is erupted and made) and tertiary (reparative dentin)
How many different types of dentin are there? What is the difference?
Fine nerve endings
What causes sensitivity within the dentin?
Tertiary dentin: when enamel and dentin is gradually lost, so odontoblasts produce tertiary dentin to protect pulp (do NOT REMOVE.. body has already repaired itself)
What are these brown spots?
Cementum
This is the hard tissue forming the surface of the root in the tooth. The periodontal ligament and gingiva attach here. Produced by cementoblasts at the apex. Produced through life and increase with age.
LOSS: prevent reattachment of periodontal lig.
HYPERCEMENTOSIS: "lock" tooth into alveolar socket (cementum fuses to bone)
What is the problem when you have loss of cementum in the tooth? What about the opposite direction with hypercementosis?
Periodontal ligament
Fibrous connective tissue which fills space between cementum of the tooth root and alveolar bone. Act as shock absorbers, transmit occlusal forces, attaches tooth to bone and cement, supply nutrients
Sharpey's fibers
What type of fibers are the periodontal ligament composed of?
Pulp (pulp chamber)
This is soft tissue connective tissue encased in root canal containing nerves, fibroblasts, collagen fibers, blood, and odontoblasts (produce dentin through the life of the tooth) = narrows with age. basically this is where nerves/arteries/veins are and you want to protect
Odontoblasts produce secondary dentin causing the pulp chamber to become narrower as the animal ages. If the dentin does not fill in the chamber with age as it should, the tooth will be very fragile
Odontoblasts line the pulp chamber (in the crown) and root canal (below crown). Who cares?
