After consult with physician, stop warfarin therapy for 4-5 days before performing dental treatment.Warfarin or heparin or LMWH can be readministered shortly (12-18 hours) after surgery.Heparin then can be discontinue 6-8 hours before surgery or Low molecular weight can be discontinued the day before surgery.Discontinue warfarin therapy several days before surgery (or other dental treatment) and substitute heparin anticoagulant therapy or Low molecular weight heparin (LMWH).After consult with physician with an unacceptable INR:. ![]() If INR is acceptable → perform dental treatment → resume warfarin therapy on the evening of the same day of dental procedure.If INR is unacceptable, defer an additional day → repeat INR → perform dental treatment only when INR is in an acceptable range → resume warfarin therapy on the evening of the same day of dental procedure.After consult with physician → 2-3 day cessation of warfarin therapy → determine INR:.Three options for alteration of anticoagulation status: Systemic, irrigant, and mouthrinse forms of tranexamic acid.Not advised to do procedures. Need to refer to physician for adjustment of warfarin therapy and evaluate all factors for risk assessment.Procedures involved high risk of bleeding: Need to refer to physician for adjustment of warfarin therapy and evaluate all factors for risk assessment.Į. Not sufficient scientific data to draw a conclusion for any INR values.Procedures involved moderate-high risk of bleeding: Need to refer to physician for adjustment of warfarin therapy.ĭ. Not advised to do procedures. Need to refer to physician for adjustment of warfarin therapy.Ĭ. Procedures involved moderate risk of bleeding:.Can be safely performed with judicious use of local hemostatic measures** in many instancesī. Procedures involved low-moderate risk of bleeding:.Procedures involved low risk of bleeding: Evaluate safety of dental treatment for patients with WarfarinĪ. Obtain an INR within 24 hours but not more than 72 hours before the procedure.If patient on a long course of warfarin therapy (> 6months):.Then, assess the safety of the dental treatment based on the INR.Urgent elective treatment such as carious teeth or periodontal disease:.can be delayed until the warfarin course has completed.For non-urgent elective treatment such as extractions or surgical procedures:.If a patient on a short course of warfarin therapy (≤ 6 months):.Presence of local factors that ↑potential for hemorrhage.Patient assement prior to any dental procedure: For NON-urgent dental care of anticoagulated patients:.Emergency Treatments such as open-fracture reduction or orthognathic surgery.Patients is currently receiving a course of cytotoxic (chemotherapy) medication.Thrombocytopenia, hemophilia or other disorder of hemostasis.Patient has one of the following medical conditions:.Referred to a dental hospital or hospital based oral/maxillofacial surgeon when:.blood clots need to be carried out before making any decision regarding the anticoagulation therapy.Īlgorithm for dental care of patients receiving anticoagulant therapy: The benefit and risk evaluation of bleeding vs.INR >5 is contraindicated for surgical procedure.Anticoagulation alteration is required if INR is >4.No alteration of anticoagulation is necessary for INR that is in therapeutic range (INR 2-4), given that local hemostaticmeasures are used.Current recommendations from the JADA based on review of published trial data are as the followings:.The majority of dental clinical literature does not support that the oral anticoagulant regimen be altered or discontinued before most dental procedures, including oral surgery.A Summary of Current Perspectives on Dental Procedures in Anticoagulated PatientsĬontroversy still exists about whether dental treatments can be safely performed while the patient is taking warfarin therapy or if the warfarin needs to be reduced or stopped entirely.
