Abstract: Objective: To evaluate the clinical efficacy of a combination of conventional treatment and compound chamomile lidocaine gel (Kamistad gel) on relieving early pain and promoting healing of extracted teeth in patients with dry socket. Methods: Eighty cases who visited the Department of Stomatology, Shunyi District Hospital of Beijing from December 2018 to December 2020 due to the occurrence of dry socket were included and randomly divided into observation and control groups, with 40 cases each. In the observation group, after wiped with hydrogen peroxide and normal saline, the alveolar fossa was evenly coated with kamistad gel and then filled with iodoform yarn strips. The control group was filled with only iodoform yarn strips after wiping. The degree of pain reduction (VAS score) on day 1, 3, and 7 after treatment, the amount of granulation tissue production within extraction sockets on day 1, 3, 7, and 14 after treatment, and the length of the disease course of dry socket were evaluated in both groups. Results: There was no significant difference in baseline between two groups (P>0.05). The VAS score of pain in the observation group was significantly lower than that in the control group in the early stage (day 1 and 3 after treatment) (P<0.05). The score of granulation tissue regeneration in the observation group was significantly lower than that in the control group at 3 and 7 days (P<0.05). The duration of dry socket in the observation group was significantly shorter than that in the control group (P<0.05). Conclusion: Kamistad gel combined with iodoform yarn strips can significantly relieve the early pain and discomfort of patients with dry socket, accelerate wound healing, and shorten the duration of the disease.
