1 Background Root canal treatment (RCT) is the primary intervention for symptomatic pulpitis, aimed at the complete eradication of the infectious source and the resolution of acute symptoms (Kohli et al. 2021). As an invasive procedure, however, it inevitably induces iatrogenic inflammation in the periapical tissues, consequently leading to postoperative pain. This makes adjunctive analgesia a critical component of post-RCT management (Kumar et al. 2025; Santos-Puerta and Peñacoba-Puente 2022).
