complications of extractions & delayed healing Flashcards
What are the 3 main complications following a paediatric extraction?
- pain
- bleeding
- local anaesthetic trauma
What are the 3 main complications following an adult extraction?
- dry socket
- post operative bleeding
- post operative infection
Why do younger children have less significant post-operative complications in terms of infection or inflammation?
Because their maxilla and mandible are well vascularised due to normal growth processes.
What is alveolar osteitis?
dry socket
What are the 4 basic stages of healing?
- coagulation
- formation of granulation tissue
- granulation tissue transferred into soft or hard tissue
- bony healing
How does alcohol impact clotting?
- reduced platelets and adhesion.
- impacts clotting factors
- inhibits inflammation
- reduces white blood cell activity increasing the risk of infection.
What are 3 types of medications that affect clotting?
(think warning cards)
- Antiplatlets
- Vitamin K antagonists
- Direct anticoagulants
Haemostatic agents are usually made from what?
Oxidised Cellulose
An INR blood test result is needed within how many hours of the extraction date?
72 hours
Which method of local anaesthetic administration should be avoided in patient’s with coagulation factor abnormalities and why?
IDBs - risk of vessel damage and haematoma development.
(this could result in obstruction to airway because of the position)
Where is a dry socket most likely to occur in the mouth?
In the mandible due to blood flow.
In what gender is dry socket more likely to occur and why?
Females due to them having different fibrolytic (clotting) system due to female hormones.
Why do smokers have an increased incidence for dry socket?
Decreased blood flow due to nicotine.
What are the typical symptoms of a dry socket?
- pain starts of day 3 and gets worse (localised to XLA site)
- deep, bony pain with poor response to analgesics
- bad taste / smell
- minimal swelling
How does dry socket appear on a radiograph?
nothing abnormal
