What is Pulpla Hyperemia?
|
Pulp's initial response to trauma, may lead to necrosis
|
|
|
What is Pulpal Bleeding?
|
Blood pigments in dentinal tubules. Color change does not mean tooth is nonvital. Color changes that occur weeks or months after injury are more indicative of necrotic pulp
|
|
|
What percent of primary teeth resorb normally?
|
90%
|
|
|
When does Pulpal Necrosis occur?
|
May occur immediately or after several monhts.
|
|
|
What is Ankylosis (Replacement resorption?
|
Results after irreversible injury to the PDL. Ankylosed primary teeth should be extracted if they cause a delay in or ectopic eruption of a developing permanent tooth.
|
|
|
What is a Concussion:
|
Injury to the tooth without displacement or mobility.
|
|
|
What is subluxation?
|
Injury to the tooth without displacement, but exhibits mobility.
|
|
|
What is avulsion?
|
Complete displacement of the tooth out of its socket
|
|
|
What is Intrusion?
|
Displacement of the tooth into the alveolar bone.
|
|
|
What are the three types of pulpal protection?
|
Calcium Hydroxide most frequent, Glass Ionomer Liner/Base (Vitrebond), Mineral Trioxide Aggregate (MTA)
|
|
|
Is treatment necessary for subluxation?
|
No, advise soft diet to prevent contamination of damaged PDL.
|
|
|
What should you do when intrusion occurs?
|
Therapeutic approach is controversial. Some advocate leaving tooth to re-erupt adn others advocate extraction. re-eruption usually occurs in 2-6 months. Do not reposition or splint intruded primary teeth. If the intruded incisor is found to be contacting the permanent tooth bud, extraction is recommended. For boards inform parent, no treatment, let tooth re-erupt.
|
|
|
Intrusion has two common characteristics...
|
Hypoplasia and arrest of tooth development are common with intrusion injuries.
|
|
|
What do you do to a luxation injury/
|
Repositioning displaced primary teeth is not recommended. Extraction. During first 6 months after injury, pulpal necrosis may occur with clinically gray or gray-black color change in crown. Leave it alone if it is asymptomatic and no pathology is noted.
|
|
|
How do you determine pulp vitality?
|
No reliable method. Traumatized teeth usually will not respond. Thermal test is most reliable especially in primary incisors.
|
|
|
What percent of primary incisors are darkened due to injury and asymptomatic?
|
80%
|
|
|
What is the pharmacologic therapy for trauma?
|
.12% Chlorhexidine Oral RInse (Reduce chance of bacterial invasion of PDL space)
|
|
|
How do you transport avulsed teeth?
|
Cold Milk, Saliva
|
|
|
What is an indirect pulp cap/
|
Near pulp, no exposure. Glass ionomer mostly used.
|
|
|
What is a direct pulp cap
|
ONly indicated in primary teeth when a pinpoint pulp exposure is encountered during cavity preparation or following a traumatic injury. Containdicated in primary teeth with a carious pulp exposure. MTA or Calcium Hydroxide is used.
|
|
|
What is a Pulpotomy?
|
Carious pulp exposure without evidence of radicular pathology. Seeral techniques-Formocreosol vs. Ferric Sulfate.
|
|
|
Pulpotomy procedure includes
|
Acheive hemostasis with Ferric sulfate,
Mix Zinc oxide powder with Eugenol liquid. Place thin layer of vitrebond to from a barrier adn light cure Titurate Fuji II LC and light cure |
|
|
What is the problem with Formocresol in pulpotomy?
|
Potential carcinogen. Both it and ferric sulfate can lead to premature exfoliation of primary teeth. No difference between success rate between the two.
