Clinical + Histological Aspects Of Tooth Socket Healing Flashcards
During tooth extraction what happens?
And what does this cause?
Coagulopathy
What is it?
What can cause coagulopathy?
What do coagulopathies lead to ?
1 - condition that affects how your blood clots, resulting in more bleeding during surgery
2 -
1. Platelet abnormality
• Number
• Function
2. Abnormal clotting mechanisms
3. Acquired & congenital coagulopathies
3 -
Failure of clot formation
Failure to achieve haemostasis
What is the first stage of healing?
What happens during clot formation
Clot formation
Features of a blood clot after 1 hour
Unstable
There is a junction between the blood clot and the PDL - adherence of clot to PDL is loose, so clot is vulnerable at this stage
Early clot formation
1 - What is it?
2 - what happens if the clot is interfered with?
3 - how is early clot formation managed ?
1 -
Early clot formation = first phase of coagulation, early clot forms but it is VERY UNSTABLE and not well anchored to the wall
2 -
Interference of clot can result in reactionary haemorrhage (hours post-op
3 -
Fibrinolysis of the clot
What is it?
Fibrinolysis of the clot begins within 2 days through conversion of plasminogen in clot to the enzyme plasmin
Give an exmaple of an antifibrinolytic
What are the steps following tooth extraction
Features of clot 1-2 days post-extraction
•Unstable clot, not adherent to socket walls
•Highest risk of total disintegration/ loss of clot during this stage
•Resultant ‘empty’ socket with exposed bone
•Risk of dry socket
Dry socket
What is it?
How many days after extraction does it occur?
Features?
Which type of teeth does it occur in?
Also called Alveolar osteitis
postoperative pain around the extraction site, between the first and third day after the extraction, accompanied by a partial or total disintegrated blood clot within the alveolar socket +/- halitosis
Aetiology of dry socket
Dry socket risk factors
Management of dry socket
Prevention of dry socket
What happens to blood clot 4 days post extraction
What does it look like clinically?
What can be found at surface of the socket?
What happens to the socket 8 days post extraction
How is it managed?
Late healing
Stages of tooth socket healing
Factors affecting tooth socket healing
What are the local factors?
What are the patient factors ?
