Week 1: Teeth, jaws, and their movements Flashcards

1
Q

Describe the basic structure of the tooth, using the words root, crown, alveolus, gingiva.

A

The root of the tooth is embedded in the alveolus, while the crown of the tooth protrudes above the gingiva

Q

Describe the formation of enamel

A

Enamel is formed by ameloblasts, which deteriorate after enamel is formed. It is the hardest substance in the body.

Q

How does dentine assist in the transmission of pain in the tooth.

A

Dentine is formed of microtubules, which in response to a stimuli (heat, cold, air, drilling, mechanical) fill the tubules, which transmit pain.

Q

Compare the growth of brachydont/ hypsodont teeth.

A

Hypsodont: continual growth of tooth throughout life

Q

How many deciduous teeth does a cat/ dog have?

A

Cat: 26
Dog: 28

17
Q

What tooth group do young animals not have?

A

Molars

18
Q

What is the deciduous dental formula of a cat?

A

2 (i 3/3 c 1/1 p 3/2) = 26

19
Q

What is the deciduous dental formula of a dog?

A

2 (i 3/3 c 1/1 p 3/3) = 28

20
Q

What side (lingual or buccal) does the permanent tooth grow on (in relation to the deciduous tooth)?

A

Lingual (tongue)

21
Q

What substance resorbs the root of the deciduous tooth?

A

Odontoclasts

22
Q

What can cause the deposition of cementum-like tissue, resulting in the fusion of the surrounding bone and loss of the periodontal ligament. And prevents the deciduous tooth falling out, impairing the tooth replacement process.

A

The process of resorption involves periods of rest and repair, if the repair prevails over resorption this occurs.

23
Q

What are the 5 surfaces of the tooth?

A

Occlusal: surface facing upper/ lower tooth (grinding surface)
Lingual: surface facing the tongue
Vestibular/ buccal: surface facing the cheek
Mesial: surface of tooth as you move towards the middle line of the mouth
Distal: surface of tooth as you move away the middle line of the mouth

24
Q

What are the 3 roots of the carnassial tooth and which is it in the dog/cat?

A

Dog: P4/M1
Cat: P3/M1
3 roots: mesiolingual, mesiovestibular, distal

25
Q

How many planes does the mandible move in, and which planes are more free in herbivores than carnivores, why?

A

3 planes.
Frontal and transverse planes are more free in herbivores because of their diet (grinding of food in mouth)

26
Q

What are the 4 pairs of muscle in the jaw involved in closure/ mastication?

A

Temporalis, masseter, lateral and medial pterygoid

27
Q

What is the origin and insertion of the temporalis muscle

A

Origin: temporal fossa
Insertion: coronoid process (mandible)

28
Q

What is the origin/ insertion of the masseter muscle?

A

Origin: zygomatic arch
Insertion: masseteric fossa

29
Q

What is the origin/ insertion of the medial/ lateral pterygoid? And which head is larger?

A

Origin: pterygopalatine fossa
Insertion: medial mandible
Medial is much larger than lateral

30
Q

What is the innervation of fascial musculature?

A

Facial nerve (CN 7) - opening/ fascial musculature
Trigeminal nerve (CN 5) - closing, fascial sensory nerve
