Postoperative Pain after Foraminal Instrumentation with a Reciprocating System and Different Irrigating Solutions

Abstract

The aim of the present study was to evaluate and compare postoperative pain after foraminal instrumentation using 5.25% sodium hypochlorite (NaOCl) or 2% chlorhexidine (CHX) gel irrigation protocol in nonvital single-rooted teeth after reciprocating instrumentation. Sixty-two volunteers presenting a single root canal diagnosed with asymptomatic necrosis and apical periodontitis were randomized into 2 experimental groups regarding the irrigation protocol (ie, 5.25% NaOCl and 2% CHX gel groups). Endodontic treatment was performed in a single session under reciprocating instrumentation with foraminal instrumentation. Volunteers were instructed to record pain intensity. Scores from 1 to 4 were attributed to each kind of pain after 24, 48, and 72 h. Kolmogorov-Smirnov and Student´s t tests were used to determine significant differences at p<0.05. On average, the percentage of patients that had no or mild pain after 24, 48 or 72 h was 77.4%, 88.7% and 95.1%, respectively. No statistically significant age difference was found between the groups (p>0.05, Student´s t test). Postoperative pain showed no statistically significant difference at any observation period when using 5.25% NaOCl or 2% CHX gel (p>0.05). Moreover, no significant difference was observed in the mean number of analgesic tablets used between the groups (p>0.05). In conclusion, the use of 5.25% NaOCl or 2% CHX gel resulted in the same postoperative pain. Therefore, it can be inferred that irrigant choice has no relation with short-term follow up regarding postoperative pain.

Retracted: Postoperative pain after irrigation with Vibringe versus a conventional needle: a randomized controlled trial

“…Many clinical trials investigated postoperative pain after the completion of root canal treatment in one visit (Gondim et al 2010, Silva et al 2015. However, in some studies, the interappointment postoperative pain was investigated to eliminate pain following the root filling originating from overfilling or extrusion of sealer (Glennon et al 2004, Ramamoorthi et al 2014.…”

Influence of anti‐inflammatory irrigant on substance P expression for single‐visit root canal treatment of teeth with irreversible pulpitis

“…This decrease in bacterial count could have contributed to reduction in inflammation and pain intensity . Sodium hypochlorite used as a root canal irrigant to help reduce post‐operative pain is supported in the literature with reasons being either due to the decrease in bacterial population or that it has better tissue dissolving capability .…”

“…As mentioned earlier, the role played by irrigant solutions on post‐operative pain is inconclusive . However, there are studies which point to a reduction in post‐operative pain by using different strengths and types of irrigating solutions . To the best of the authors’ knowledge, there are no studies evaluating the use of NSAIDs as root canal irrigating solutions and their efficacy in single‐visit root canal treatment for teeth with irreversible pulpitis.…”

“…The role of irrigating solutions employed during root canal treatment to help control post‐operative pain is unclear . While certain studies have observed a reduction in post‐operative pain with particular types and concentrations of irrigating solutions, other studies have reported no difference in post‐operative pain with the different irrigating solutions .…”

Safety assessment of an etidronate in a sodium hypochlorite solution: randomized double‐blind trial

“…Patients may experience discomfort and pain following root canal treatment (Pak & White 2011). Several variables are associated with this outcome, including factors related to root canal irrigation (da Silva et al 2015). Various methods are described to evaluate the intensity of postoperative pain (Ferreira-Valente et al 2011).…”
