Abstract Objective: To observe and explore the efficacy of C-shaped root canal filling with hot gutta-percha vertical condensation and iRoot SP cold lateral condensation in the treatment of periapical Periodontitis of permanent teeth and the influence on pain and prognosis. Methods: Totally 146 patients with periapical periodontitis of permanent teeth treated in the hospital between March 2018 and March 2021 were selected as the observation subjects, and they were divided into hot vertical condensation group (73 cases) and cold lateral condensation group (73 cases) according to different treatment method. Both groups were subjected to routine oral examination, and on this basis, the hot vertical condensation group was given hot gutta-percha vertical condensation method for root canal filling treatment, and the cold lateral condensation group adopted iRoot SP cold lateral condensation for root canal filling treatment. The filling effect, clinical efficacy, periodontal pain degree, periodontal indexes and prognosis were compared between the two groups. Results: There was no statistical difference in filling effect between cold lateral condensation group and hot vertical condensation group (P>0.05). After 3 months of treatment, the total effective rate was 93.15% in cold lateral condensation group and was 82.19% in hot vertical condensation group (P<0.05). There was a statistical significance in the periodontal pain VAS score in terms of between-group effect, time-point effect and interaction effect of between-group and time-point (P<0.05), and the periodontal pain VAS score in the two groups showed a decreasing trend after treatment, and the decreasing degree in cold lateral condensation group was significantly greater than that in hot vertical condensation group (P<0.05). Before treatment, the differences in the levels of periodontal indexes were not statistically significant between cold lateral condensation group and hot vertical condensation group (P>0.05). After 3 months of treatment, the periodontal indexes of the two groups were significantly decreased compared to before treatment (P<0.05), and the decreasing degrees of indexes before and after treatment of cold lateral condensation group were significantly greater than those of hot vertical condensation group (P<0.05). At 6 months of follow-up after treatment, the recurrence rate of 2.00% in cold lateral condensation group was lower than 12.50% in hot vertical condensation group (P<0.05). Conclusion: Hot gutta-percha vertical condensation and iRoot SP cold lateral condensation for C-shaped root canal filling have a good filling effect in the treatment of periapical periodontitis of permanent teeth, but iRoot SP cold lateral condensation has a more significant therapeutic effect and can effectively reduce the pain degree and re-infection rate of patients, and it has a better prognosis and is worthy of clinical promotion and application.

Key words： Hot gutta-percha vertical condensation iRoot SP cold lateral condensation C-shaped root canal filling Periapical periodontitis of permanent teeth
