Oral SurgeryFor a patient on dicoumarol therapy with a prothrombin time of 18 seconds, surgery can be performed as this PT is only mildly elevated and within acceptable limits for minor oral surgery. Normal PT is 11-15 seconds, and a PT of 18 seconds represents manageable anticoagulation levels that don't significantly increase bleeding risk for tooth extraction.
