Abstract: Objective: To evaluate the effect of colloidal silver gelatin sponge on prevention of complications following dental extraction in diabetics. Methods: A total of 300 diabetic patients undergoing dental extraction in our hospital were included in this study from January 2019 to January 2020, who were divided into three groups. In the experimental group, the teeth extraction sockets were filled with the Gelatamp colloidal silver gelatin sponge, and the control group with medical absorbable gelatin sponge. The socket remained empty in blank control group. The incidence of bleeding was observed on 0.5 and 24 hours after extractions, and the infection rate was observed on 3 and 7 days postoperatively. Results: The bleeding and infection rates of the experimental group were 5% and 4%, respectively, compared with 12% and 13% for control group and 21% and 20% for blank control group. The experimental group had significantly lower incidence of the complications such as bleeding and infection. Additionally, the level of white blood cells of the experimental group was lower than the other groups. Conclusion: The colloidal silver gelatin sponge has an advantage on hemostasis and anti-inflammation, which can significantly prevent the occurrence of complications following dental extraction in diabetic patients.
