Summary
This review found no significant difference in postoperative pain or flare-ups between single-visit and multiple-visit root canal treatments. More research is needed to definitively compare these endodontic approaches.
Area of Science:
- Endodontics
- Dental Pain Management
Background:
- This systematic review evaluated postoperative pain and flare-up prevalence following single-visit versus multiple-visit nonsurgical root canal treatment.
- Searches included major databases (Cochrane, Medline, Embase) and thesis/conference repositories without language restrictions.
Discussion:
- Sixteen studies with sample sizes ranging from 60 to 1012 cases were included.
- Significant heterogeneity across studies precluded a meta-analysis, limiting quantitative synthesis.
- Qualitative synthesis indicated a wide range (3-58%) in reported postoperative pain prevalence.
Key Insights:
- Current evidence does not strongly support one root canal treatment approach (single- vs. multiple-visit) over the other regarding postoperative pain or flare-up incidence.
- The variability in study methodologies and outcome reporting highlights challenges in comparing treatment modalities.
Outlook:
- Further high-quality, standardized research is necessary to establish definitive clinical guidelines.
- Future studies should focus on consistent outcome measures and control for confounding factors to enable robust meta-analyses.
