Given the growing trend towards medical indications for continuous use of
anticoagulants, the number of patients on these medications continues to rise. The management of patients on oral
anticoagulants requiring
oral surgical procedures has aroused much controversy. Changes in an anticoagulation regimen are associated with an increased risk of
thromboembolism. However, it seems logical and advantageous for the patients' health if surgery could be performed without any change to the anticoagulation
therapy. In dentistry, high-power
lasers have been poorly explored in this field. The
hemostatic properties of high-power
lasers could be helpful during oral soft tissue surgeries in anticoagulated patients. The aim of this study was to compare bleeding time in anticoagulated rats after
lingual frenectomy performed with a scalpel or
diode laser with bleeding time in healthy animals. Twenty-four male Wistar rats were assigned to four groups (n = 6): (CS) Control-Scalpel Surgery; (AS) Anticoagulated-Scalpel Surgery; (CL) Control-
Laser (diode laser 810 nm/1.5 W) Surgery; and (AL) Anticoagulated-
Laser Surgery (
diode laser 810 nm/1.5 W).
Warfarin administration was used to induce anticoagulation. Blood was blotted every 30 seconds with filter paper until
bleeding stopped to verify bleeding time. Two blinded researchers performed the surgeries and collected the bleeding time data.
Diode laser surgery led to complete hemostasis in rats during and after
lingual frenectomy. Zero
bleeding was assessed during surgeries and after
diode laser surgeries in anticoagulated rats.
Laser-induced hemostasis offered an alternative
solution to the controversial issue of intraoperative and postoperative
bleeding control in patients on anticoagulation
therapy.
