It is generally expected that the time required for a clot to form in an extraction socket must be similar to that of the average physiological bleeding time (2 −9 minutes). However, in dental practice does hemostasis require the full clot to form or does it occur earlier?
Conventionally there is no accepted average time range for socket hemostasis with estimates ranging from 20 minutes to 40 minutes. The study was attempted to quantify the average time period required for hemostasis to occur in an extraction socket.
1205 consecutive patients attending the dental clinic and requiring dental extractions were evaluated for the average duration of hemostasis after extraction. Exclusion criteria were children (<15 years), pregnant mothers and patients who had a systemic bleeding disorder or were on anticoagulants.
The socket was inspected first after five minutes after an extraction and later at 10 minutes and 15 minutes if bleeding continued.Hence it is expected that in an otherwise normal healthy individual socket compression by biting over gauze for around 10 minutes will produce adequate haemostasis. Prolonged bleeding beyond 10 minutes was rare and was controlled with suturing and pressure applied with a gauze pack in healthy individuals.
Conclusively, Checking for hemostasis after placing a pressure pack for 5 −10 minutes over an extraction socket is a useful act of risk management before discharge of the patient from the clinic to rule out any hemorrhagic tendency.
