Q

what is the etiology of inflammatory resorption?

A
  • surface resorption of cementum exposing dentinal tubules
  • pulp necrosis
  • toxic products from the pulp provoke an inflammatory response in the PDL

Q

what is replacement resorption?

A
  • direct union of bone and root
  • resorption of root and replacement with bone
  • direct result of loss of vital PDL

16
Q

what are treatment alternatives in class III fractures of primary teeth?

A
  • direct pulp capping
  • CaOH pulpotomy
  • pulpectomy
17
Q

how successful are CaOH partial pulpotomies?

A

96% success with pulps exposed 1 hour to 90 days

18
Q

what is the technique for CaOH partial pulpotomy?

A
  • gently remove dentin and pulp to 1-2mm
  • use copious irrigation
  • cover pulp with CaOH
19
Q

what are the properties of mineral trioxide aggregate?

A
  • high pH (similar to CaOH)
  • exceptional sealing properties
  • hardens within hours enabling canal obturation
20
Q

what is the criteria for successful pulp therapy on traumatized teeth?

A
  1. absence of clinical signs and symptoms (fistula, mobility, pain)
  2. completion of root development
  3. absence of radiographic signs of necrosis
21
Q

an injury to the tooth supporting structures without abnormal loosening or displacement of the tooth but with marked reaction to percussion

A

concussion

22
Q

an injury to the tooth-supporting structures with abnormal loosening, but without displacement of the tooth

A

subluxation

23
Q

what is the treatment for concussion?

A
  • inform patient and parent about potential sequelae

- monitor

24
Q

what is the tx for subluxation?

A
  • DO NOT splint
  • Follow up in 2 weeks
  • radiograph at one month
25
Q

what is the tx for intrusive luxation with an OPEN apex

A
  • if less than 7mm, allow spontaneous repositioning
  • —if no movement in 3 weeks reposition orthodontically
  • if more than 7mm, reposition surgically
26
Q

what is the tx for intrusive luxation with a CLOSED apex

A
  • if less than 3mm, allow spontaneous respositioning
  • if 3-7mm, extrude tooth orthodontically (ASAP)
  • if more than 7mm, surgically reposition tooth
27
Q

what is the treatment for extrusive luxation?

A
  • reposition tooth ASAP (best if within 2 hrs)
  • light splint for 2 weeks
  • remove pulp and fill with CaOH within 7-14 days
  • CHX
  • complete endo fill in 2 months if no inflammatory reaction
28
Q

what is the treatment with lateral luxation?

A
  • reposition tooth ASAP (best if within 2 hrs)
  • light splint for 3-4 weeks
  • remove pulp and fill with CaOH within 7-14 days
  • CHX
  • complete endo fill in 2-4 months if no inflammatory resorption
29
Q

what is the tissue of most concern when dealing with an avulsed tooth?

A

PDL

healing without resorption
*most critical factor

30
Q

what is the tx for an avulsed tooth?

A
  • management at site of injury (reimplant immediately)
  • transport media
  • management at dental office
  • adjunctive drug therapy considerations
  • endo treatment
  • restoration of the avulsed tooth
31
Q

what are the recommended transport (storage) media for an avulsed tooth?

A
  • socket (immediate reimplantation)
  • cell culture medium
  • milk
  • physiologic saline
  • saliva
32
Q

what is the maximum extraoral (dry time) that a tooth can be out of the socket?

A

less than one hour

  • handle by crown, gently reimplant
  • splint
  • remove pulp in 7-14 days
33
Q

what is the management of the soft tissues of an avulsed tooth?

A

tightly suture any soft tissue lacerations particularly in the cervical region

34
Q

as far as splints go, what is recommended and what is contratindicated?

A

good to use: fish line, acid etch resin, soft arch wire, ortho brackets, suture as last resort

bad to use: circuferential wire

*maintain splint for 7-10 days, longer if tooth demonstrates excessing mobility

35
Q

what is splinting home care?

A
  • no biting on splinted teeth
  • soft diet
  • maintenance of good oral hygiene
36
Q

what is the endodontic tx for an avulsed tooth with less than one hour dry time?

A
  • remove pulp in 7-14 days
  • place CaOH
  • obturate canal in 2-12 months
37
Q

what is the objective of managing an avulsed immature tooth?

A

revitalize severed pulp

  • best chance if reimplanted in 20 minutes (max 60)
  • soak in doxycycline solution for 5 minutes
  • reimplant and splint
  • recall every 3-4 weeks
38
Q

what are some additional considerations for avulsed teeth?

A
  • require follow-up for at least 5 years
  • DO NOT reimplant primary teeth
  • potential complications include
  • –inflammatory resorption
  • –replacement resorption
  • –tooth submergence
