Q

What does an osteoclast do?

A

Dissolve the roots of the baby teeth (i.e. the permanent teeth dissolve the roots of the baby teeth)

Q

What is a likely cause for a patient to claim that their tooth is feeling a bit high?

A

The tooth actually is lifting out of the mouth slightly due to hydraulics from fluid build-up at the base of the tooth

Q

What are the objective symptoms you can check, and what are the associated results you can expect if healthy?

A
  • -Pain with percussion (find a healthy tooth for baseline)
  • -No/slow response or no/slow recovery to cold or electricity (3-5 seconds to respond, and about the same time to recover)

Q

Do all roots contain a single canal?

A
  • -NO, MF roots of max molars usually contain 2 root canals (MB1, MB2)
  • -Mesial roots of mandibular molars have 2 root canals (MF, ML)
  • -However, there are exceptions to all the rules (remember the body doesn’t read the anatomy text book)

Q

Are root canals normally performed on baby teeth?

A

NO, because baby teeth roots are wider, and have a better vascular supply

Q

What are the 6 steps of Root Canal Treatment (RCT)?

A 
1-Diagnose
2-Access Pulpal Chamber
3-Determine length of canal
4-Clean chemically and mechanically
5-Obturate (fill) with gutta percha and sealer
6-Restore tooth with crown or filling

Q

What does it mean to retrofil?

A

Procedure of filling the end of the canal. MTA is used to do the retrofil (MTA is concrete, but is very biologically compatible)

20
Q

What type of exercise is good to increase bone volume and density?

A

Weight bearing exercise

21
Q

What is the pulp chamber and how are its surfaces named?

A
  • -The pulp chamber is the expanded area inside the crown

- -The walls are named after the outer tooth surface they are closest too (facial, distal, mesial, etc.)

22
Q

What is reversible pulpitus?

A

The condition resulting from pulpal trauma, but not full breakdown of the pulpal tissue

23
Q

What is the periodontal ligament (PDL)?

A

The ligament that surrounds the roots and connects them to the bone

24
Q

When must a root canal treatment (RCT) be performed?

A

When the tooth contains irreversible pulpitus

25
Q

What is the bone called that supports the teeth?

A

Alveolar bone

26
Q

What is the depression in the alveolar bone where the teeth sit called?

A

Alveolar socket, or alveolus

27
Q

Are healthy teeth in direct contact with the bone?

A

No, they are actually held in place by a short ligament called the periodontal ligament (PDL), which connects the bone to the cementum covering the root of the tooth
–Essentially teeth hang in a sling made up of the PDL and are allowed to move freely in any direction though the amount of movement is small

28
Q

What happens when a tooth is extracted?

A

The periodontal ligament (PDL) is torn

29
Q

What is the oral muccosa?

A

The term used to generally describe the thin layer of tissue lining the inside of the mouth and alveolar bone

30
Q

How does the color of the oral muccosa change with increasing stress?

A

It becomes more pink

31
Q

What does gingiva mean?

A

Gums

32
Q

What is the unattached portion of the gingiva that is pyramid in shape and fills the space between the teeth called?

A

Inter-dental papilla

33
Q

What is the sulcus?

A

The trough-like depression that circles each of your teeth between the gums and the teeth

34
Q

What depth should the sulcus be in a healthy mouth?

A

Less than 3.5mm all around the tooth

35
Q

What is stippling?

A

The “orange peel” appearance of the gums due to the fibers which attach the gingiva to the bone

36
Q

What marks the boundary between the attached gingiva and unattached gingiva?

A

The PDL

37
Q

What is the muccogingival junction?

A

Forms the boundary between the gingiva and the mucosa

38
Q

How do the gums change color when they have gingivitis?

A

The gums turn from pink, to dark pink or red

39
Q

At what depth is gum disease considered advanced?

A

Greater than 5.5mm

40
Q

How periodontal disease related to the number of roots a tooth has?

A

It is directly related

41
Q

What is a cavitron used for?

A

It is an instrument that vibrates very quickly to perform deep cleaning or scaling to help treat periodontal disease

42
Q

What is the number one reason for tooth loss in the United States?

A

Gum disease

43
Q

Are the bacteria the cause tooth decay the same or different from those that cause gum disease?

A

DIFFERENT

44
Q

What bacteria destroys teeth?

A

S. Mutans

45
Q

How many bacteria cause gum disease?

A

Over 30

46
Q

What predispositions can a patient have for developing periodontal disease?

A 
•	Lack of good hygiene
•	Genetics
•	diseases like diabetes
•	Smoking and drug use
•	Number of roots
•	Family members with gum disease
o	If your spouse has really healthy gums, kiss like crazy because they have healthy bacteria
