Treatment
of the Avulsed Permanent Tooth
|
|
|
| I.
Management at Site of Injury |
| |
A.
Replant immediately, if possible. If contaminated, rinse with
water before replanting. |
| |
B.
When immediate replantation is not possible, place tooth in
the best transport medium available. |
|
| II.
Transport Media |
| |
A.
Hank's Balanced Salt Solution (H.B.S.S.) |
| |
B.
Milk |
| |
C.
Saline |
| |
D.
Saliva (buccal vestibule) |
| |
E.
If none of the above is readily available, use water. |
|
| III.
Management in the Dental Office |
| |
A.
Replantation of Tooth |
| |
| |
1.
If extraoral dry time is less than 2 hours, replant immediately. |
| |
2.
If extraoral dry time is greater than 2 hours, soak in
a topical fluoride for 5 - 20 minutes. rinse with saline
and replant. |
| |
3.
If tooth has been in any physiological storage media (such
as H.B.S.S., milk, or saline), replant immediately. |
|
|
| |
B.
Management of the Root Surface |
| |
| |
1.
Keep the tooth moist at all times. |
| |
2.
Do not handle the root surface (hold tooth by the crown).
|
| |
3.
Do not scrape or brush the root surface or remove the
tip of the root. |
| |
4.
If the root appears clean, replant as is after rinsing
with saline. |
| |
5.
If the root surface is contaminated, rinse with H.B.S.S.
or saline (use tap water if above are not available).
If persistent debris remains on root surface, gently use
cotton pliers to remove remaining debris and or gently
brush off debris with a wet sponge. |
|
|
| |
C.
Management of the Socket |
| |
| |
1.
Gently aspirate without entering the socket. If a clot
is present, use light irrigation with saline. |
| |
2.
Do not curette the socket. |
| |
3.
Do not vent socket. |
| |
4.
Do not make a surgical flap unless bony fragments prevent
replantation. |
| |
5.
If the alveolar bone is collapsed and prevents replantation,
carefully insert a blunt instrument into the socket to
reposition the bone to its original position. |
| |
6.
After replantation, manually compress (if spread apart)
facial and lingual bony plates. |
|
|
| |
D.
Management of Soft Tissues - tightly suture any soft tissue
lacerations, particularly in the cervical region. |
|
| |
E.
Splinting (indicated in most cases) |
| |
| |
1.
Use acid-etch resin alone or with soft arch wire, or use
orthodontic brackets with passive arch wire. Suture in
place only if alternative splinting methods are unavailable.
(Circumferential wire splints are contraindicated.) |
| |
2.
Splint should remain in place for 7-10 days; however,
if tooth demonstrates excessive mobility, splint should
be replaced until mobility is within acceptable limits. |
| |
3.
Bony fractures resulting in mobility usually require
longer splinting periods (2-8 weeks). |
| |
4.
Home care during splinting period should encompass:
| |
a.
No biting on splinted teeth |
| |
b.
Soft diet |
| |
c.
Maintenance of good oral hygiene |
|
|
|
|
|
| V.
Endodontic Treatment |
| |
A.
Tooth with open apex (divergent apex) and less than 2 hours
extraoral dry time:
| |
1.
Replant in an attempt to revitalize the pulp. |
| |
2.
Recall patient every 3-4 weeks for evidence of pathosis. |
| |
3.
If pathosis is noted, thoroughly clean and fill the
canal with calcium hydroxide (apexification procedure). |
|
| |
B.
Tooth with open apex (divergent apex) and greater than 2 hours
extraoral dry time:
| |
1.
Thoroughly clean and fill the canal with calcium hydroxide. |
| |
2.
Recall the patient in 6 - 8 weeks. |
|
| |
C.
Tooth with partially to completely closed apex and less than
2 hours extraoral dry time:
| |
1.
Remove the pulp in 7-14 days. |
| |
2.
Medicate the canal with calcium hydroxide. |
| |
3.
Obturate canal with gutta percha and sealer after 7-14
days of calcium hydroxide. |
|
| |
D.
Tooth with partially to completely closed apex and greater than
2 hours extraoral dry time:
| |
1.
Perform root canal therapy either intraorally or extraorally. |
| |
2.
If treated extraorally, avoid chemical or mechanical damage
to root surface. |
|
|
| VI.
Restoration of the Avulsed Tooth |
| |
A.
Recommended Temporary Restorations (placed prior to final obturation)
| |
1.
Reinforced zinc oxide eugenol. |
| |
2.
Acid etch/composite resin. |
|
| |
B.
Recommended Permanent Restorations (placed immediately after
final obturation)
| |
1.
Dentin bonding agent. |
| |
2.
Acid etch composite resin. |
|
|
| Vll.
Additional Considerations |
| |
A.
Avulsed primary teeth should not be replanted. |
| |
B.
Avulsed permanent teeth require follow up evaluations for a
minimum of 2- 3 years to determine the outcome of therapy. |
| |
C.
Inflammatory resorption, replacement resorption, ankylosis,
and tooth submergence are potential complications when avulsed
teeth are replanted. |
