Question 1

PULPITIS

Answer 1

inflammation of the pulp

Question 2

PERIODONTITIS

Answer 2

Inflammation of the periodontium

Question 3

Acute Symptoms

Answer 3

moderate to severe symptoms of a short duration (days - weeks)

Question 4

Chronic Symptoms

Answer 4

Mild or no symptoms of long duration usually months to years

Question 5

Periradicular

Answer 5

pertaining to any part of or the entire radicular/root region of a tooth

Question 6

Apical

Answer 6

end/tip/last third of the tooth root

Question 7

Healthy pulp

Answer 7

tooth is asymptomatic and gives mild to moderate response to thermal testing and EPT
RADIOGRAPH SHOWS clearly demarcated canal that tapers smoothly toward apex - no calcification seen & lamina dura is intact

Question 8

Is reversible pulpitis a disease?

Answer 8

No, it is a transient condition of the pulp

Question 9

How does reversible pulpitis present?

Answer 9

generally asymptomatic pulp - but it is inflamed and will give a quick sharp response to thermal (cold) stimulus lasting no more than a few seconds once the stimulus is removed

Question 10

clinical evidence of reversible pulpitis

Answer 10

history of dental caries, perio scaling, root planning, recent unbased restoration, enamel fracture exposing dentine

Question 11

Is spontaneous or unprovoked pain associated with reversible pulpitis?

Answer 11

no

Question 12

how does reversible pulpitis present radiographically?

Answer 12

Normal - except for evidence of caries or coronal fracture without direct pulp involvement

Question 13

is RCT needed for Reversible Pulpitis?

Answer 13

No. –> conservative tx is reqd.

Question 14

how to treat reversible pulpitis?

Answer 14

conservative tx -

1. remove caries & place restoration
2. remove unbased restoration & place liner under new filling eg Ca(OH)2 [dycal]
3. restore fractured tooth - once it is treatable - to cover exposed dentinal tubules
4. Restore any other lesions with composite or GIC

Question 15

what is disclusion?

Answer 15

a separation of the teeth when the jaw is slightly open

Question 16

When is pain felt on a cracked tooth?

Answer 16

only on disclusion

Question 17

What causes pain in a cracked tooth

Answer 17

On disclusion when the oral fluids are driven w/in the crack in a pulpal direction

Question 18

what special investigation is used to identify a cracked tooth?

Answer 18

tooth slooth or wooden stick used for selective biting to reproduce pain on release. - careful!! –> this can extend the fracture
TRANSILLUMINATION test & Application of a dye ( eg Methylene blue or iodine sol’n)

Question 19

can a cracked tooth be detected radiographically?

Answer 19

usually no.

Question 20

what indicated a good prognosis or treatable cracked tooth?

Answer 20

if the apical extent of the crack ends coronal to the level of the crestal bone.
