Postoperative Pain after Use of the WaveOne Gold and XP-endo Shaper Systems: A Randomized Clinical Trial

The Comparative Evaluation of Postoperative Pain After the Use of WaveOne Gold and TruNatomy Filing Systems in a Tooth With Irreversible Pulpitis: An Observational Study

“…An isolated variable for preoperative pain was set to avoid bias, the variable being selecting teeth with the preoperative diagnosis of irreversible pulpitis to eliminate the possibility of intracanal drugs or other variables causing discomfort, and all of the teeth are treated in one visit [ 14 ]. The volume, concentration, and kind of irrigating solution used in all endodontic treatments, as well as root-filling operations, are all standardized [ 14 ]. As a result, both professionals and patients have thoroughly appreciated the importance of the VAS and its implementation [ 1 ].…”

“…They stated that future in vivo research comparing the prevalence to the degree of postoperative discomfort following mechanical preparation is necessary for further association, and the current study confirms their findings. The comparative study by Xavier et al (Postoperative pain after use of the WaveOne Gold and XP-endo Shaper systems: a randomized clinical trial) [ 14 ] concluded that the reciprocating WaveOne Gold filing system shows less postoperative pain when compared to the rotatory XP-endo Shaper (FKG Dentaire, La Chaux-de-Fonds, Switzerland). Martins et al [ 24 ] discovered that when compared to a rotating system, a reciprocating system causes reduced postoperative pain (p<0.05).…”

“…On the basis of the comparative study by Xavier et al (Postoperative pain after use of the WaveOne Gold and XP-endo Shaper systems: a randomized clinical trial) [ 14 ], the mean and standard deviation for postoperative pain in the WaveOne Gold group at 24 hours were 0.68 and 1.55, respectively, and the mean and standard deviation for postoperative pain in WaveOne Gold group at seven days were 0.00 and 0.00, respectively; therefore, the mean difference between 24 hours and seven days is 0.68. The pooled standard deviation between 24 hours and seven days was 1.55/2=0.775.…”

“…Short-term pain (24-72 hours) is to be expected but will lessen after seven days, according to these findings [ 14 ]. The WaveOne Gold system uses patented heat treatment to improve the instrument's flexibility, cutting efficiency, and cyclic fatigue resistance [ 3 , 14 ]. These properties favor the maintenance of the path after curved root canal preparation, which justifies its use in our study.…”

“…It rotates 360° in three cycles at a speed of 350 rpm (150° counterclockwise {CCW} and 30° counterclockwise and alternating clockwise movements) [10,[11][12][13]. Short-term pain (24-72 hours) is to be expected but will lessen after seven days, according to these findings [14]. The WaveOne Gold system uses patented heat treatment to improve the instrument's flexibility, cutting efficiency, and cyclic fatigue resistance [3,14].…”
