Introduction: Odontomas are the most common type of odontogenic tumors. They are classified as mixed odontogenic tumors, being divided into compound and complex types, usually asymptomatic and diagnosed on radiographic examinations. Treatment consist of simple local excision. Hemophilia A is a genetic disorder characterized by prolonged bleeding caused by the decrease or absence of the coagulation factors (factor VIII) required for blood clot formation. Case report: Patient complaining of “jaw pain and bad taste in the mouth,” reporting to have hemophilia A. He presented a blotting and traumatic ulcer in the left mandibular ramus; CT scan showed a hyperdense lesion with hypodense halo, well defined and with well-defined borders. The diagnostic hypothesis was complex odontoma. Thirty minutes before surgery, coagulation factor VIII was restored. Intraoral access was performed, followed by mucoperiosteal detachment, section of the lesion with drill 702 in smaller portions, to facilitate removal, and copious suture. Conclusion: The surgical removal was satisfactory and conservative, using the principles for extraction of included teeth, there were no complications due to coagulopathy. The theoretical basis and a detailed surgical planning were fundamental for the conduction and favorable prognosis of this clinical case.
