Importantly, factor VIII and factor IX deficiencies or severe factor XI deficiencies are associated with an increased risk of bleeding, whereas even drastic reductions of factor XII or rarely occurring high molecular weight kininogen and prekallikrein deficiencies do not cause excessive bleeding (4).

Se registraron los siguientes parametros: edad, clasificacion de la coagulopatia (hemofilia A, hemofilia B, enfermedad de von Willebrand y deficiencia de factor XII), dientes cariados, perdidos y obturados/cariados, extraidos y obturados (CPO-d/ceo-d), (12-13) indice gingival (presencia o no de gingivitis), presencia o no de maloclusiones y adherencia al tratamiento.
Among the clotting factors studied, factor XII (FXII) levels exhibited one of the highest heritabilities (67%) and a significant positive genetic correlation with thrombotic disease [5], indicating that some of the polymorphisms and mutations that influence variation in this physiological risk factor also influence liability to thrombosis.
Blood Tests found larger amounts than normal of an element in the blood called Activated Factor XII. `High levels have been associated with an increased tendency for abnormal blood clotting and this is a risk factor for heart disease and all vascular disease.
Investigation of her clotting cascade revealed a moderate deficiency of factor XII (42%) which was unlikely to be an aetiological factor.

The juice of CD reduced CT possibly by enhancing the coagulation process by intrinsic path way which may involve the reaction of factor XII, factor XI, factor IX or factor VIII.
The endogenous thrombin potential represents the total amount of thrombin that can be generated as a function of the balance between the procoagulant drivers (coagulation factors downstream from factor XII) and the anticoagulant drivers (namely, antithrombin and PC) operating in plasma.
