Knowledge and attitude of dental students in treating patients on antiplatelet and/ or anticoagulant medications

Meshari N. Alabdulkarim, Sundar Ramalingam


Background: Antiplatelet and anticoagulant medications are widely prescribed for the prevention of thromboembolic events. Dental management of patients taking such medications can be troublesome because of the possibility of excessive bleeding during surgical procedures. On the other hand, stopping these medications will increase the risk of thromboembolic complications. This study aimed to evaluate the level of knowledge and attitude of dental students and internship trainees at King Saud university in treating patients on antiplatelet and/or anticoagulant medications.

Methods: A 17-question survey was distributed among dental students in third, fourth, and fifth (seniors) academic year levels, as well as internship trainees. The survey included questions aiming to evaluate participants’ knowledge in treating patients on antiplatelet and/or anticoagulant medications. A total of 281 surveys were returned complete.

Results: In our study, most participants were aware of aspirin (86.1%) and warfarin (92.2%) but only a few were aware of newer medications like rivaroxaban (10.7%) or apixaban (8.2%). The majority of participants would consult with the patient’s physician (76.9%) before stopping any medications and/or would rely on local hemostatic techniques to control bleeding (70.8%).

Conclusions: In this study, we concluded that only a small percentage of participants were aware of and following the latest guidelines. The findings of the present study suggest a need for educational programs and workshops regarding this topic.
