- Compare the healing rate and post-obturation pain of single- versus multiple-visit root canal treatment for teeth with infected root canals.
- N= 10 articles met inclusion criteria (6 compared healing rate and 5 compared post-op pain)
- Inclusion criteria: Mature permanent teeth, radiographic evidence of apical periodontitis, at least 1 year follow up.
- Literature search combined with specified inclusion criteria was performed to identify randomized or quasi-randomized controlled trials (RCTs or quasi-RCTs), comparing root canal treatment in single and multiple appointments (2 or more visits) in patients with infected root canals
- No significant difference was observed in the healing rate between single- versus multiple-visit root canal treatment
- Prevalence of post-obturation pain was significantly lower in single-visit than in multiple-visit group.
The healing rate of single- and multiple-visit root canal treatment is similar for infected teeth. Patients experience less frequency of short-term post-obturation pain after single-visit than those having multiple-visit root canal treatment.
