Oral PathologyHemophilia causes prolonged coagulation time due to deficiency of intrinsic pathway clotting factors (Factor VIII in Hemophilia A, Factor IX in Hemophilia B). This results in prolonged activated partial thromboplastin time (aPTT) and whole blood clotting time. Leukemia may cause bleeding due to thrombocytopenia or leukostasis but not primarily prolonged coagulation time. Pernicious anemia and malignant neutropenia do not directly affect coagulation cascade.

EndodonticsCommon sequelae of replanted avulsed tooth are ankylosis and resorption of roots. These complications occur due to: 1) Periodontal ligament damage during avulsion and handling, 2) Extended extraoral time leading to PDL cell death, 3) Inflammatory response triggering resorptive processes, 4) Direct bone-root contact causing ankylosis, 5) Root surface damage predisposing to replacement resorption. These complications are more common when extraoral time exceeds 30 minutes or when the tooth is stored in inappropriate media. Proper immediate management can reduce but not eliminate these risks.
