Bleeding After Dental Extractions In Cardiac Patients On Anticoagulants Reduced By Protocol
Clinicians need a protocol to reduce the risk of substantial bleeding after dental extractions in cardiac patients who take anticoagulant medications. Findings in a study published in the current issue of the Journal of Oral Implantology reveal that the use of leukocyte- and platelet-rich fibrin biomaterial, a material commonly used in dentistry to improve healing and tissue regeneration, is a safe filling and haemostatic material after dental extractions. Researchers assessed the use of the biomaterial in 50 heart patients who received oral anticoagulant therapy with warfarin after a mechanical valve substitution.
Addition Of Mannitol Increases Effectiveness Of Dental Nerve Block Anesthesia
Allowing a patient to be comfortable and pain-free during surgical and restorative dental procedures is an essential part of the process. The most commonly used local anesthetic injection for lower teeth is the inferior alveolar nerve (IAN) block. However, failure rates ranging from 10 to 39 percent have been reported. The current issue of the journal Anesthesia Progress presents a study testing the efficacy of adding a solution of mannitol to the anesthetic typically used in IAN blocks. Forty adult subjects participated in the study, receiving an IAN block at each of three separate appointments at least one week apart.
F. Nucleatum Enables Breaking Bond On Blood Vessels To Allow Invaders In
A common oral bacteria, Fusobacterium nucleatum, acts like a key to open a door in human blood vessels and leads the way for it and other bacteria like Escherichia coli to invade the body through the blood and make people sick, according to dental researchers at Case Western Reserve University. Yiping Han, professor of periodontics at the Case Western Reserve School of Dental Medicine, made the discovery in her continued work with the Fusobacterium nucleatum bacterium, one of the most prevalent of the more than 700 bacteria in the mouth.
