25
The PDL absorbs the injury and is inflammed.
Concussion.
26
Tx for concussion.
None
27
Increased mobility but not displaced from the socket.
Subluxation
28
The tooth is not mobile or displaced.
Concussion
29
Tx for subluxation
None. Recommend a soft diet and good oral hygiene to prevent contamination of the damaged PDL. Can do chlorhexidine that's alcohol free on the affected area with cotton swabs twice a day for a week.
30
This happens if you have concussion or subluxation after a while.
Tooth discoloration
31
What do you do if you see a gray baby tooth?
70% of the time, you do nothing.
32
Does color change in a tooth indicate the need for pulp therapy or extraction?
No, there has to be periapical pathology, signs of infection, etc.
33
What does pink discoloration indicate?
1) Recent injury where the capillaries in the pulp are hemorrhaging and releasing blood into the crown space. 2) Internal root resorption
34
What does yellow discoloration indicate?
Pulp calcification. Good prognosis
35
Tx for yellow discoloration.
Monitor
36
This causes dark discoloration of the tooth.
RBC's containing hemogolobin stain the tooth dark.
37
What percent of untreated dark discolored primary incisors remain without radiographic or clinical pathology?
70%
38
The tooth is completely out of the socket.
Avulsion
39
This percent of avulsions involving a primary have a damaged developing successor.
75%.
40
Should you reimplant an avulsed BABY TOOTH?
No! Can do damage to the permanent successor.
41
Someone with a congenital heart defect who has a heart valve that's been completely repaired needs to pre-medicate for low long after the procedure was done?
6 months
42
Do artificial heart valves need premedication?
Yes
43
a history of this bacterial heart disease needs premedication.
Infective endocarditis
44
Does a cardiac transplant that develops a heart problem need premedication?
Yes
45
Dislocation of the tooth in an axial direction into the alveolar bone.
Intrusion
46
If my baby tooth is intruded, want to figure out the position of it in relation to the permanent incisor.
True
47
When would you extract an intruded tooth.
If it's impinging on the permanent successor.
48
What does buccal inclination of the crown indicate in intrusion?
The root is hitting the permanent tooth germ, and the baby tooth needs to be extracted ASAP.
49
What does lingual inclination of the baby crown indicate in intrusion?
The baby root is towards the buccal plate, away from the tooth germ, so just let it re-erupt.
50
Foreshortened and opaque tooth. What does this say about the type of intrusion?
Okay to keep in. The root is buccal, away from the follicle.
51
Elongated root on x-ray indicate what about the intrusion type?
EXTRACT= elongated The root is going towards the lingual, into the follicle.
52
Intruded primary teeth, unlike adult teeth, maintain what?
Pulp vitality.
53
Describe the PDL space on a radiograph for an extruded tooth.
Widened around the apex.
54
If the extrusion is less than 3 mm, what do you do?
Reposition or allow it to spontaneously realign.
55
What to do if the extrusion is greater than 3 mm?
Extract with LOCAL ANESTHESIA!
56
What do you do in a horizontal root fracture where the coronal fragment is only moderately or slightly displaced?
Reposition and splint
57
What to do in a horizontal root fracture if the coronal segment is really displaced?
Extract, but leave the root tips in so you don't damage the permanent successor.
58
The tooth is usually not mobile in this type of injury bc the root is forced into the bone.
Lateral luxation.
59
Alveolar bone fracture is often caused by this type of injury.
Lateral luxation.
60
This type of injury is often associated with a swollen upper lip due to fracture of the buccal bone plate by the tooth apex.
Lateral luxation
61
Lateral luxation treatment if there's no occlusal interference, like in an anterior open bite.
Allow to spontaneously reposition.
62
Lateral luxation treatment if there's occlusal interference.
Give local and manually reposition.
63
Lateral luxation treatment for teeth with severe displacement in a labial direction.
Extraction.
64
Teeth have mobility of the alveolar process in this type of oral trauma.
Alveolar fracture (buccal and lingual plates are fractured).
65
Splint these two types of oral trauma.
Root fracture and Alveolar fracture.
66
General anesthesia is indicated for this type of oral trauma.
Alveolar fracture.
