Abstract Objective: To compare the clinical efficacy of the single-file system WaveOne Gold and ProTaper nickel-titanium rotary instruments in one-visit root canal therapy (RCT). Methods: A total of 150 patients who underwent one-visit RCT at our hospital from July 2021 to July 2023 were divided into two groups based on the root canal preparation instruments used: the study group (n=77, WaveOne Gold single-file system) and the control group (n=73, ProTaper nickel-titanium rotary instruments). The success rate of one-visit root canal preparation, root canal preparation time, root canal filling quality, postoperative pain at 24h and 48 h, and patient satisfaction were compared between the two groups. Results: The study group exhibited a higher success rate of one-visit root canal preparation and shorter root canal preparation time compared to the control group (P<0.05). The rate of optimal root canal filling was also higher in the study group (P<0.05). At 24h and 48 h postoperatively, the visual analog scale (VAS) scores in the study group were significantly lower than those in the control group (P<0.05). Additionally, patient satisfaction with root canal preparation, filling, and overall treatment was higher in the study group compared to the control group (P<0.05). Conclusion: Compared to ProTaper nickel-titanium rotary instruments, the WaveOne Gold single-file system demonstrates superior efficacy in one-visit RCT. It significantly improves the success rate of one-visit root canal preparation, enhances root canal filling quality, reduces preparation time, and alleviates postoperative pain.

Key words： One-visit root canal therapy Single-file system Nickel-titanium rotary instruments Root canal filling quality Postoperative pain
