RESUMO
Minor oral surgery can give rise to bleeding intra- and post-operatively. This can be minimal in most patients; however, it can be more problematic in patients with impaired clotting disorders, liver disease, or taking any form of anticoagulation therapy. Haemostatic agents are available to overcome such bleeding risks. The topical application of 1:1000 adrenaline used in medicine can be considered for use in dentistry. Adrenaline is widely used within medicine, surgery and dentistry. Examples include its use in local anaesthetic agents, in the management of anaphylaxis and as part of the cardiopulmonary resuscitation algorithm. 1:1000 adrenaline used topically for ear, nose and throat surgeries has shown improved visual fields during surgery with better surgical outcomes. It is relatively safe, but in patients with cardiovascular comorbidities, it should be practised with caution. This has precipitated the idea for its use within oral surgical procedures, including canine exposures, third molar surgery, root displacement into the antrum and periapical surgery. The haemostatic effect of 1:1000 adrenaline as an alternative should be considered in operative dentistry and oral surgery to aid in haemostasis and improve intra-operative visualisation, reducing the risk of iatrogenic damage and bleeding, thereby improving treatment outcomes.
