Clinical Trial Summary
This study aimed to evaluate postoperative pain intensity after glide-path preparation with
the ProGlider (PG) and WaveOne Gold Glider (WOGG) systems in asymptomatic teeth with necrotic
pulp and periapical lesions.Maxillary and mandibular molars with chronic apical periodontitis
of 78 patients (age, 18-65 years) were included. The patients were randomly divided into
three groups: control (n = 26), PG (n = 26), and WOGG (n = 26). All systems were used
according to the manufacturer's instructions, and all root canal treatments were completed by
a single operator within two sessions. Postoperative pain was assessed using a numerical
rating scale (NRS) at 6, 12, 18, 24, 48, and 72 h. The intake of prescribed analgesics and
abscess formation were also recorded.
Description:
Pain after root canal treatment is an important complication encountered in endodontic
practice, with a reported prevalence of 3%-58%. Severe pain may start even 24 to 48 h after
treatment. Postoperative pain has a complex etiology, including treatment factors under the
control of the clinician, microbial factors related to the contents of infected root canals,
patient demographic factors (patient sex and age, among others), immunological factors, local
tissue changes, and psychological factors. Debris extrusion to the periapical tissues during
root canal instrumentation can significantly influence the incidence and intensity of
postoperative pain. The root canal instrumentation technique may play an important role in
the occurrence of postoperative pain as it can induce an acute inflammatory response
following periapical extrusion of necrotic tissues, infected debris, and bacteria. Previous
clinical trials have evaluated the effect of reciprocation and continuous rotation kinematics
on debris extrusion and postoperative pain; however, their results are conflicting.
The glide path is defined as a straight tunnel extending from the canal orifice to the
physiological apical foramen. Glide-path preparation may prevent complications of root canal
instrumentation; reduce risk of instrument failure, debris extrusion, and postoperative pain;
and preserve root canal anatomy, thereby reducing the risk of transportation, perforation,
and step and zip formation. Many NiTi glide-path file systems of different sizes and
metallurgical properties have been introduced to date. Recently, a new single glide-path file
system was introduced with the aim of reducing the number of files used and simplifying
glide-path instrumentation.
The effect of glide-path file systems on postoperative pain has been studied previously.
However, to the best of investigators' knowledge, there are no data comparing PG and WOGG
glide-path files in terms of postoperative pain in asymptomatic teeth with necrotic pulp and
periapical lesions. Therefore, the purpose of this in vivo study was to evaluate the
incidence and intensity of postoperative pain in asymptomatic maxillary and mandibular molars
with necrotic pulp and periapical lesions after glide-path preparation with a stainless-steel
K-file and PG and WOGG glide-path file systems. The null hypothesis was that there is no
difference in the incidence and intensity of postoperative pain between glide-path
preparation techniques.
