Abstract

Introduction: Cleaning and shaping are necessary to allow for the delivery of irrigants and medicaments to the apical third of the canal. Standard treatment irrigation generally uses a conventional needle and some frequency of sonic activation. The GentleWave System (GWS; Sonendo, Inc, Laguna Hills, CA) combines irrigant delivery with multisonic activation. This randomized clinical trial aimed to determine if the GWS significantly decreases the incidence and intensity of postoperative pain. Methods: Patients used a numeric rating scale to record their pain level at the 6-hour time point before treatment. All participants were randomly divided into 2 groups and were blind to the treatment they received. The standard (control) group received endodontic treatment with conventional side-vented needle irrigation and ultrasonic activation. The second group received treatment with the GWS. Following treatment, patients used a numeric rating scale to record their pain level at 6, 24, 72, and 168 hours. Results: In the standard treatment group, 72.2% of patients experienced at least 1 occurrence of postoperative pain, whereas in the GWS group, 83.3% of patients experienced at least 1 occurrence of postoperative pain. The highest pain intensity level for both treatments occurred at the 6-hour posttreatment time point. All pain decreased with time after the 6-hour posttreatment time point (P < 1.237e−7). Conclusions: There was no significant difference in the incidence or intensity of postoperative pain after either treatment group. However, both groups reported a statistically significant decrease in pain with time.
