Abstract：Objective To evaluate the clinical efficacy of the new bioceramic material C-Root SP in root canal filling for elderly patients with pulpitis.Methods From January 2023 to December 2024,101 elderly patients who visited the Department of Stomatology of Beijing Hepingli Hospital and needed root canal treatment due to pulpitis were enrolled in this study.They were randomly divided into C-Root SP group(33 teeth),iRoot SP group(33 teeth)and AH Plus group(35 teeth)using computer-generated random number method.All root canals were prepared by crown downward method.Three types of root canal sealers were used respectively,and the root canals were filled by hot gutta percha vertical compression method.X-ray films were taken before and after treatment.The pain of the three groups on the day of root canal filling,1 d,3 d and 7 d after operation were recorded by visual analogue scale(VAS).The clinical efficacy was observed after 3 months of follow-up.Results On the day after root canal filling surgery,the VAS score of AH Plus group was significantly higher than that of C-Root SP group(P＜0.05).On day 1 and 3 after root canal filling surgery,the VAS scores in the AH Plus group were significantly higher than those in the C-Root SP group and iRoot SP group(P＜0.05);There was no significant difference in VAS scores between the C-Root SP group and the iRoot SP group(P＞0.05).After 7 days of root canal filling surgery,there was no significant difference in VAS scores among the C-Root SP group,iRoot SP group,and AH Plus group(P＞0.05).At a 3-month follow-up after surgery,there were no cases of failure in all three groups,and there were no significant differences between the three groups or between the two groups(P＞0.05).Conclusion C-Root SP has good clinical efficacy and biocompatibility in elderly patients with pulpitis,similar to iRoot SP.
