Abstract:Objective:To compare the comprehensive efficacy of fractional multiple-stage root canal therapy versus single-stage complete root canal therapy in treating various dental pulp diseases. Methods:A total of 130 patients with dental pulp diseases admitted to the Department of Stomatology from September 2024 to January 2026 were enrolled, randomly divided into a control group(fractional root canal therapy)and a treatment group (single-stage root canal therapy; each group n=65) using a random number table. The total clinical efficacy rate,visual analog pain scores (VAS) at 3 days and 7 days post-treatment,serum levels of inflammatory marker(s TNFα,IL-6,CRP)before and at 14 days post-treatment, total treatment duration,and incidence of postoperative complications were recorded and statistically compared between groups. Results:The clinical total efficacy rate in the treatment group was 95.38%,significantly higher than that in the control group(76.92%;P<0.05). VAS pain scores at 3 days and 7 days post-treatment,as well as serum inflammatory markers at 14 days post-treatment,were significantly lower in the treatment group (P<0.05). The total treatment duration was shorter in the treatment group,while the overall incidence of complications such as gingival swelling,apical irritation, occlusal discomfort,and instrument separation was only 6.15%,markedly lower than that in the control group 21.54% ( P<0.05). No statistically significant differences were observed between the two groups regarding baseline gender,age, or disease classification (P>0.05). Conclusion: Single-stage root canal therapy enables completion of pulpal exposure, preparation,disinfection,and filling in one procedure,significantly shortening the treatment cycle,reducing postoperative pain and systemic inflammation,minimizing complications,and achieving better long-term healing outcomes,making itparticularly suitable for patients with simple acute/chronic pulpitis or those without severe apical abscesses. Complex and extensive apical lesions can still be treated with staged endodontic therapy,and the clinical approach should be flexibly selected based on the severity of the lesion in the affected tooth.
