Abstract

Aims and objectives: To assess the effectiveness of chitosan-based dressing after extraction in individuals on antithrombotics, without modification of their treatment schedule.

Materials and methods: A randomized comparative study was carried out on 40 subjects who had two extraction sites, in dissimilar quadrants. The surgical site was chosen at random and post-extraction hemostasis was achieved by a custom-cut chitosan dressing (study site) and sterile cotton gauze dressing (suturing if required) at control site. Patients were reviewed on the first, third, fifth, and seventh postoperative days and every week till 4 weeks. The parameters assessed were timing of hemostasis, pain scores, and pus discharge.

Results: Out of 40 study subjects, 24 (60%) were males and 16 (40%) were females. The age was 40-65 years (mean age 54 years). The mean time for hemostasis was 0.63 ± 0.27 min in study group, whereas for controls, it was 9.10 ± 2.28 min. The difference in postoperative pain was significant (P = 0.001) on days one, five, and seven. In chitosan group extraction sites, dry socket was not seen, whereas four patients on day three and five patients on day five after extraction experienced dry socket in pressure gauze dressings group, with an insignificant difference (P = 0.058). In chitosan group extraction sites, no pus discharge was seen. Whereas four patients on days three and five after extraction had pus discharge in patients where pressure dressings were applied, with an insignificant difference (P = 0.058).

Conclusion: Chitosan dressing is a competent hemostatic agent that significantly reduced the post-extraction bleeding, with better pain control. Chitosan group had no incidences of dry socket and pus discharge.

Keywords: Chitosan; myocardial infarction; oral antithrombotic drugs; post- extraction bleeding; thromboembolism.
