Tooth extraction leads to bleeding which may be longer in patients on antithrombotics. This study was aimed to evaluate the hemostatic and wound healing efficacy of chitosan-based dressing in comparison to the cotton pressure pack after tooth extraction in patients receiving single or dual antithrombotics.This is a prospective, randomized split mouth study. Patients undergoing tooth extractions taking either single or dual antithrombotics, with an international normalized ratio (INR) value ≤ 3 were enrolled at JSS Dental CollegeHospital, Mysuru, India during February 2020 to January 2022. The study compared the efficiency of chitosan dressing in achieving quicker hemostasis in comparison to cotton pressure pack. The primary outcome was time to achieve hemostasis and the secondary outcomes were alveolar clinical healing index and alveolar osteitis. The covariates were gender, age, reason for extraction, INR, type of antithrombotic therapy, and the disease condition.Of the 54 enrolled subjects, 39 were males and 15 were females, aged between 33 and 86 years. Thirty six patients were on single antithrombotics, whereas 18 patients were on dual antithrombotics. The reason for extraction was periodontitis in 37 patients and dental caries in 17 patients. The time to achieve hemostasis was lesser with chitosan dental dressing when compared to cotton pressure packs (96 ± 4 and 797 ± 23 seconds; P .001). In the chitosan group, the time to hemostasis was similar irrespective of single or dual antithrombotic therapy (90 ± 6 and 109 ± 8 seconds, respectively). On the contrary, in the cotton pressure pack group, patients on dual antithrombotics had longer time to achieve hemostasis compared to those on single antithrombotics (940 ± 20 and 726 ± 26 seconds; P .001). The time to achieve hemostasis was dependent on INR only in cotton pressure pack group (rWhen compared to cotton pressure packs, chitosan-based dressing was more effective in controlling postoperative bleeding in patients treated with single and dual antithrombotic therapy. |
