Managing postoperative pain in individuals suffering from symptomatic irreversible pulpitis and apical periodontitis is crucial for effective endodontic treatment. This study evaluated the impact of different irrigation techniques—positive pressure, negative pressure, and sonic activation—on pain relief and medication requirements.
In patients with pulpitis and periodontitis, the use of negative pressure irrigation results in less postoperative pain and fewer analgesic needs than traditional side-vented needle irrigation.
Managing postoperative pain in individuals suffering from symptomatic irreversible pulpitis and apical periodontitis is crucial for effective endodontic treatment. This study evaluated the impact of different irrigation techniques—positive pressure, negative pressure, and sonic activation—on pain relief and medication requirements.
A total of 48 eligible patients (aged 16-65) with single-rooted teeth diagnosed with pulpitis and periodontitis were enrolled. Participants were randomly allocated to 3 groups using computer-generated block randomization: positive pressure irrigation (conventional side-vented needle group), negative pressure irrigation, and sonic activation.
This randomized controlled trial included 2 visits for root canal therapy, where 3% sodium hypochlorite (NaOCl) irrigation was performed. Pre-surgical data documentation encompassed patient demographics, tooth-specific information, and pain severity estimated using a visual analogue scale (VAS). Pain levels and analgesic usage following treatment were assessed at set intervals.
Postoperative pain analysis indicated that the negative pressure group experienced the least pain, followed by the sonic activation and positive pressure groups, with marked differences at 6 and 24 hours. Analgesic requirements were aligned with pain levels, with the positive pressure irrigation group needing the most analgesics and the negative pressure group requiring the least analgesics, underscoring the effectiveness of the interventions.
When compared to conventional side-vented needle irrigation, the negative pressure irrigation substantially mitigated postsurgical discomfort and analgesic requirements. These results yield valuable insights and support research-backed guidelines for streamlining endodontic practices while ensuring patient well-being and optimal results.
