Postobturation pain at 1 week · People aged 10 years or above requiring root canal treatment; permanent teeth with completely formed apex and without internal resorption
It is very uncertain whether single-visit root canal treatment changes postobturation pain at 1 week compared with multiple-visit root canal treatment (two or more visits) (very low certainty).

Overall success (composite of clinical and radiographic success) · Human permanent teeth with symptomatic irreversible pulpitis due to carious pulp exposure
In symptomatic irreversible pulpitis, pooled pulpotomy success was 84% (95% CI 72-92%); not significantly different from asymptomatic (z=-1.34, p=0.18); ungraded.

Treatment failure (annual failure rate) · Children with carious primary molars treated by pulpotomy (vital pulp therapy)
Preformed metal crowns had a low annual failure rate (2.4%) in primary molars after pulpotomy, lower than amalgam in the same trial (single high-risk-of-bias RCT; low quality of evidence; not GRADE-rated).

Radiological failure (periapical radiolucency) after at least 1 year · People aged 10 years or above requiring root canal treatment; permanent teeth with completely formed apex and without internal resorption
Single-visit root canal treatment showed no clear difference in radiological failure (periapical radiolucency) after at least 1 year compared with multiple-visit root canal treatment (two or more visits) (moderate certainty).
