To the Editor:—
In the interim since the preparation of the paper referred to, we have continued to conduct dental extractions while patients have been under therapeutic levels of anticoagulant drugs. This markedly decreases the risk to many patients suffering from thromboembolic conditions. This procedure has been carried out in approximately 50 additional patients without complications. In our paper we described the control of the therapy and surgical techniques which has proved to be safe. We recommend that others adopt this approach. The fact that the conclusions of Ziffer et al. have been requoted and "condoned" by others has not contributed new knowledge. On the other hand, the original paper and the recent letter of Dr. J. M. Askey (JAMA176:746 [May 27] 1961) are based on actual experience with this problem. This technique is now being widely adopted in leading medical centers.
