1

What is Barodontalgia?

  • Tooth pain caused by an increase or decrease in ambient pressure
  • Usually reported by aircraft personnel and divers
  • Tough to diagnose...pulp testing inconclusive
  • Affects teeth with a vital pulp - defective restoration
  • Look for etiology of chronic pulp inflammation

2

What is an enamel Infraction?

Incomplete fracture (crack) of the enamel without loss of tooth substance

3

Define an Uncomplicated Crown Fracture...

No Pulp Exposure: fracture with loss of enamel only or with loss of enamel and dentin 

4

Define Uncomplicated Crown-Root Fracture...

No Pulp Exposure - fracture involving enamel, coronal and redicular dentin, and cementum

5

Define Complicated Crown Fracture...

Pulp Exposure: Fracture involving enamel and dentin with pulp exposure

6

Define Complicated Root Fracture...

Pulp Exposure: Fracture involving radicular dentin, cementum, and pulp; further classified according to coronal fragment displacement

7

Define Ellis Class I, II, and III tooth fractures...

  • Ellis Class I - Enamel Only
  • Ellis Class 2 - Enamel + Dentin
  • Ellis Class 3 - Enamel + Dentin + Pulp

8

What are signs/symptoms of "Incomplete" Tooth Fracture?

  • Biting Pain
  • Hypersensitivity
  • Visible Fracture
  • Narrow Probing Defect
  • Aka...cracked tooth syndrome

9

What are some possible treatment options for an Incomplete Tooth Fracture?

  • Cuspal Protection
  • Endodontics
  • Extraction

10

What are the most commonly cracked teeth?

Mandibular Molars - 70%

11

Describe observation and treatment for a Vertical Root Fracture...

  • Begins in root and moves coronally
  • Oriented F to L
  • Usually previous RCT
  • Narrow probing defect w/sinus tract at base
  • 2 narrow probing defects on opposite sides of root
  • Treatment: Extraction

12

What is a tooth Concussion?

13

What is tooth Subluxation?

14

What is Tooth Extrusive Luxation?

15

What is Lateral Luxation?

16

What is Intrusive Luxation?

17

What is going on in this picture?

Concussion

18

What is going on in this picture?

Extrusive Luxation

19

What is going on in this picture?

Lateral Luxation

20

What is going on in this picture?

Intrusive Luxation

21

What is the least to most severe in Prognosis?

Extrusive Luxation, Intrusive Luxation, Concussion, Subluxation, Lateral Luxation...

  • Concussion
  • Subluxation
  • Extrusive Luxation
  • Lateral Luxation
  • Intrusive Luxation

22

Describe Surface Resorption...

Self Limiting

23

Describe Inflammatory Resorption...

Infection

24

Describe Replacement Resorption...

Ankylosis

25

Observe Prognosis of Luxation Injuries on Immature Roots...

26

Observe Prognosis of Luxation Injuries of Mature Roots...

27

Which type of luxation injury triggers the highest amount of resorption?

Intrusion

28

Post trauma, pulp may not respond to...

Thermal or EPT!

29

How long can it take for the pulp to respond normally post trauma?

2 - 10 Months

Initial positive response may revert to negative within 2 months ...usually indicates pulp necrosis

30

Is it important to get a baseline thermal test?

Yes
