Abstract

Introduction: We previously reported that blue-violet LED irradiation immediately controls socket bleeding following tooth extraction. We applied the same technique to extracted sockets in warfarin administrating patients and examined its effectiveness on the hemos-tasis.

Materials and Methods: All patients (N = 26) admi-nistrated warfarin were necessary to extract their teeth. PT.INR (prothrombin time-international normalized ratio) were measured. Blue-violet LED irradiation (20 sec) was performed to 17 patients after the tooth extraction. Other 9 patients were applied with spongel as the control. When bleeding continued even after 30 sec, the sockets were sutured for preventing further bleeding.

Results: All patients showed 1.68-2.97 PT.INR. After 20 sec LED irradiation 11 patients showed a clear hemostasis at their extraction sockets. Other 6 patients needed suturing for hemostasis. On the other hand, all the 9 control patients, who were applied with spongel, needed suturing after 30 sec. Statistically significant difference was found between LED irradiated and the control groups.

Conclusion: Blue-violet LED irradiation showed about 65% hemostasis of socket bleeding and ameliorated the bleeding of warfarin administrating patients.
