Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: This study was designed as single blind, randomized control trial. Sixty patients with symptomatic teeth requiring endodontic canal treatment were recruited by probability random sampling into two groups based on irrigation protocols used during endodontic treatment: conventional needle and endo activator irrigation system. The post-operative pain of patients was recorded via a telephone call at 6 hours, 24 hours, and at 7 days on the visual analogue scale (VAS).
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
NaOCl is the widely used irrigation solution during chemo-mechanical instrumentation as it has a broad range of antibacterial effect and a high capacity of organic tissue dissolution. It has the dissolution capacity when used in concentrations as low as 2.5%, resulting in decreased antibiofilm effect and removal of organic part of smear layer. Similarly, use of EDTA during the preparation removes the organic part of smear layer resulting in exposure of dentinal tubule and for better penetration of NaOCl for disinfection.1 The same protocol and irrigation techniques were followed in our study to maximize the benefit of NaOCl and EDTA during endodontic treatment.
Many studies have examined effects of different various irrigation methods in relation with endodontic procedures on post-operative pain that corroborate with results of this current study. In this study, working length was determined by use of apex locator i.e. electronic measurement device for root canal length which was then confirmed by digital radiograph. This protocol was followed to ensure that preparation was confined within root canal space, and prevent chances of over instru¬mentation that is considered to be one of those major leading cause of post-operative pain.
The Endoactivator System results in minimal extrusion of irritants and irrigate simulated lateral canals at 4.5 and 2 mm from desired working length as compare to that with conventional methods resulting in better irrigation and decreased post-operative pain among different variables.The highest values of post-operative pain were recorded after 6 hours of treatment that potentially decreased in the follow-up periods until almost disappeared after the time interval of one week. In studies evaluation regarding duration of post-operative pain after root canal treatment was noted in regard with above mentioned aggrement.
Studies by Gondim et al and Topçuoğlu et al also reported lower values of pain in Endovac group com¬pared to conventional needle irrigation showing sig¬nificantly marked results after 6 hours followed by 48 hours-time interval. The chances of extrusion of debris apically was greater resulting in increased level of pain with conventional needle-syringe irrigation due to positive pressure of conventional irrigation.
Nivedhitha S 4 in their study concluded that postoperative pain in patients when irrigation was done by means of endoactivator significantly reduced from 6 hours (35.7 ±17.2) to 7 days (4.8±7.4). Topçuoğlu, concluded that after 24 hours, pain in the conventional irrigation group was higher 3.96± 1.95 while endo activator caused mild pain 2.36±1.32.9 Gündoğar in his study concluded that postoperative pain at 48 hours in conventional irrigation group was 0.23±0.63 while that in the endoactivator group was 0.07±0.37.2 Similarly, in the present study canals irrigated by means of endoactivator reported less post-operative pain as compared to canals irrigated with conventional irrigation.
In the present study, the pain score at 6 hours was 4.82±2.690, while at 24 hours was 3.13±2.62 and reduced significantly at 7 days to 1.55±1.789.
The study is aimed to evaluate comparison related to post-operative pain after use of Endoactivator and conventional irrigation during endodontic treatment in symptomatic periapical periodontitis. The VAS scale is a common acceptable method for measuring postoperative pain in research related to dentistry. This scale was described in detail to the patient before recording their pain intensity on the VAS scale so as to reduce significant chances of errors that patients could make while describing their pain intensity. Therefore, patients were made familiar to the VAS and were assisted accordingly in recording their preoperative and postoperative pain conditions. 20 A recent systematic review by Romualdo et al21 stated that apical extrusion of irrigant was considerably less when using apical negative pressure compared in case of using positive pressure techniques. The conclusive findings elaborated that the negative apical pressure decreases the chances of apical extrusion. In the present study, less pain scores were seen in group of endoactivator as compared to those in conventional irrigation group in first 6 hours. These results may be related to fact that chances of extrusion are less in endoactivator group in comparison to the conventional irrigation group. Tang et al 22 in his study also compared the level of post-endodontic pain after single-visit root canal treatment after 24 hours and after one week time interval. However, level of pain was markedly lower in ultrasonic groups compared to the conventional irrigation group at 24 hours and one week after the procedure.
In the first 6 hours after treatment, the greatest post-operative pain scores were seen in both groups, while subsequent observation time points at 24 hours and 7 days showed significant reduction in pain level in both the study groups. Studies that have evaluated postoperative pain after endodontic treatment have reported similar results. 1,4 Pak and White4 in a systematical review concluded that the prevalence of pain diminished from 40% at 24 hours post-endodontic treatment to 11% at the 7th post-operative day.
One of the strengths of this study was random allocation of patients to groups to minimize confounders. Single operator carrying out all the procedures helped to avoid technical errors and standardize the endodontic procedure. Standard protocols for root canal treatment were adhered to in both the study groups for effective root canal treatment to ensure that the post-operative pain could be attributed only to the difference in irrigation protocols.
Despite of certain strengths, the present study focused primarily on vital pulp of single-rooted teeth with fully formed apices, treated in single visit. Therefore, these results may not directly apply to cases involving multi-rooted teeth or immature apices. Moreover, pain is often difficult to measure and can be attributed to multiple variables, so the pinning only one specific cause of pain is quite difficult. In future, studies can be carried out on multirooted teeth with necrotic pulp, treated in multiple visits to evaluate the effect of endoactivator irrigation or other sonic irrigation methods to assess their effect on post endodontic pain incidence.
CONCLUSION:
This study found that intensity and severity of post-operative pain occurring in patients presenting with symptomatic periapical periodontitis was significantly reduced by use of endoactivator when used with 2.5% NaOCl 7 days after single-visit endodontic treatment.
