Hemostasia is a defense mechanism that protects vascular integrity, avoids blood loss, and maintains blood fluidity throughout the circulatory system. The biochemical processes leading to blood clot formation are complex, and alterations can appear at any point within the chain of events. While a range of alterations can affect the coagulation factors, some are more common than others in the general population, including congenital (hemophilia A and B, Von Willebrands disease) and acquired disorders (anticoagulant drugs). Such diseases require special consideration in the context of dental treatment, and therefore must be known to dental professionals. Interconsultation with the hematologist will provide orientation on the characteristics of the disease and on the best approach to treatment, including the need for replacement therapy, the application of local hemostatic measures, the modification of anticoagulant therapy, etc. In any case, the most important concern is the prevention of bleeding complications by compiling a detailed clinical history, with adequate planning of treatment, and taking special care to avoid soft tissue damage during the dental treatment of such patients. The dental surgeon must enhance awareness among patients and their relatives of the importance of correct oral hygiene, which will help avoid the need for invasive dental treatments and will reduce the number of visits to the dentist
