pulp and responces to trauma

Question 1

diagnosis

Answer 1

• Built on clinical history (own words)
• Examination crucial (may need to refer onwards if unable to examine facial skeleton properly)
• Confirm with special tests

Question 2

types of damage to pulp

Answer 2

instant trauma
- pulp would bleed
long term
- pulp will have sclerosed

Question 3

tests supplement to history

Answer 3

dental radiographs
sensibility test
precussing the tooth
colour of tooth

Question 4

sensibility test

Answer 4

ethyl chloride
can be placed on normal tooth to see if nerves working
test tooth vitality
tooth may still be vital but not react to test

Question 5

percussing tooth

Answer 5

• Use of end of a dental mirror to knock the tooth
• Make the PDL slightly springy
• Look to see if PDL is inflamed
• Inflammation can occur if tooth has been knocked
• Will be tender to knocking

Question 6

pulpitis

Answer 6

• Inflammation of the pulp

- Due to irritant chemicals, excessive heat, bacteria and their toxins

Question 7

avulsion - effects on tooth and pulp

Answer 7

• With apical foramen, more likely to be reimplanted and stay vital (apical foramen closes as a person ages)
• Blood vessels get more likely to be torn as patient is older
• Highly dependant on collagen not being denatured

Question 8

necrosis - effects on tooth/pulp

Answer 8

• Vessels going through a small apical foramen
• Vessels ruptured, free vessels cannot enter apical foramen (during eg knock)
• Blood and pulp in tooth eventually break down

Question 9

fracture - effects on tooth/pulp

Answer 9

• Tooth would be sensitive (especially through dentine)
• Holes (ones for odontoblast processes) are a route for bacteria to get to pulp
• Infection can lead to an abscess

Question 10

prevention of trauma

Answer 10

mouthguard
aware of heat fro appliance to prevent collagen burning
restoration will prevent pulpitus

Question 11

apexificition

Answer 11

apex continues to grow and close

Question 12

tooth ache cause and steps

Answer 12

1) irreversible pulpitis
2) necrosis of pulp
3) pain subsides
4) may be formation of an abscess
5) pain reoccurs

Question 13

what happens after an access occurs and the pulp has necroses

Answer 13

removal of the pulp
-root filling
or extraction of tooth

Question 14

removal of the pulp

Answer 14

• disinfect root canal system
• extract pulp tissue
• pulled root canal system
• allows healing within bone by not placing filling materal outside of root filling

Question 15

compostite

Answer 15

binds to the tooth rather than amalgam which wouldn’t bond to cusp well

Question 16

pulp cap

Answer 16

if pulp is still vital odontoblasts may still be reactivated §

Question 17

how is a pulp cap done

Answer 17

place a material over the pulp
attempt to differentiate odontoblasts into dentine
dentine bridge forms underneath

Question 18

materials that can be used for a pulp cap

Answer 18

calcium hydroxide
- used as resin
causes necrosis of dental pulp, kills off bacteria on pulp and causes clot on pulp to prevent blended
MTA
- cells like to grow up and against it
better than CaOH
Biodentine
- matrix which encourages odontoblasts to grow with in it

Question 19

what is laid down to protect pulp

Answer 19

reparative dentine induced

pulp is vital

Question 20

dentine responce to grinding teeth

Answer 20

mild inflammatory response in dentine, odontolasts reactivated reactionary dentine produced so smaller pulp chamber
