What type of haemorrhage occurs during an extraction?

During a dental extraction, primary haemorrhage is the type that occurs immediately following the procedure. This form of bleeding typically results from the severing of blood vessels during the extraction, causing blood to flow from the site of the extraction right away. It is crucial for dental professionals to manage this type of bleeding effectively, as it can lead to complications if not addressed promptly.

In contrast, reactionary haemorrhage occurs a few hours after the procedure due to the reaction of the tissues to the surgery, while secondary haemorrhage happens days later, often related to infection or the dislodging of a clot. Post-operative haemorrhage can refer more generally to any bleeding that occurs after the extraction, which may include reactionary and secondary haemorrhage. Understanding these different classifications helps in proper monitoring and management of bleeding events associated with dental extractions.
