Level of evidence: C

Both partial- and full coronal pulpotomy can be used in the treatment of deep carious lesions in permanent teeth with reversible pulpitis.

«Alqaderi H, Lee CT, Borzangy S ym. Coronal pulpoto...»1 SR/MA Studies on coronal pulpotomy for carious vital pulp exposure of permanent posterior teeth 402 → n=32 → n=6
PICOS, Prisma
Trauma teeth excluded
USA 1960–2015
Intervention: full coronal pulpotomy with MTA or Ca(OH)2 Main outcome: weighted mean success* rate (WSR)
Success* was defined in studies at 12 m and 24 m:
no radiographic abnormality or clinical symptoms, resolution of an existing radiographic periapical lesion, and no need for further pulpectomy and RCT of the treated teeth.
RCT: Cochrane Collaboration's tool
n=1, 7/9 Low risk of bias
The prospective or retrospective cohort studies: Newcastle–Ottawa scale (NOS)
n=5, 4.6 ± 0.5/9
Studies heterogeneity 1 year i2 63.6%, two year i2 83.8%
MTA studies respectively I2 = 75.3% and 86.6%

88 → n=21 (17)
Two medicaments were used: MTA or Ca(OH)2
Two articles compared the outcome at two time points, three compared outcome of pulpotomy to root canal treatment and one to direct pulp capping
Success: clinical/ radiographic/overall success rates (both clinical and radiographic) at least 12 m follow-up Cochrane Handbook for Systematic Reviews of Interventions
No trial was considered to have low risk of bias in all items.
All trials had high risk regarding performance bias resulting from the lack of blinding of participants and/or clinicians.

Spain
Partial pulpotomy performed in permanent carious teeth with MTA or Ca(OH)2 Outcome: success or no signs of inflammation/necrosis clinically or radiographically with follow-up period of at 6, 12 and 24 months In case of heterogeneity, subgroup analysis was performed, and the results were visualized with a forest plot, and publication bias was evaluated with the funnel plot and Egger contrast.

Reference Comments
General Because of the high risk of bias in the included studies, the evidence was considered to be fair (C), even if outcomes were similar. Variation was great in the outcomes as well as heterogeneity of the studies (#1, 6, 7). Also risk bias regarding performance was high resulting from the lack of blinding of participants and/or clinicians (#2, 4). The studies were non randomized follow-up studies (I.e. #5)
«Alqaderi H, Lee CT, Borzangy S ym. Coronal pulpoto...»1 Ca(OH)2, MTA, CEM (MTA like products) used in studies included; Studies that performed other procedures, including apexo- genesis, direct or indirect pulp capping, partial pulpotomy, were excluded.
«Li Y, Sui B, Dahl C ym. Pulpotomy for carious pulp...»2 Partial pulpotomies included. Non-randomized controlled trials, non-comparative studies and observational studies were, excluded because the high risk of bias associated with those studies could compromise the results of meta-analysis. Glutaraldehyde and formocresol pulpotomy were excluded because of the toxicity of the medicaments. Studies with fewer than 10 participants in one treatment arm were considered non-representative.
«Zanini M, Hennequin M, Cousson PY. Which procedure...»3 No controls, no modelling; here clinical studies included; reversible/irreversible pulpitis/ pulp necrosis with/without periapical findings as indication, hemostasis irrigation or compression commonly up to 10 minutes;
«Chen Y, Chen X, Zhang Y ym. Materials for pulpotom...»4 Partial pulpotomy and pulpotomy, immature teeth, in one study trauma teeth included, otherwise only carious
«Tan SY, Yu VSH, Lim KC ym. Long-term Pulpal and Re...»5 Prospective, clinical study, no controls
Inclusion: Teeth with demonstrable bleeding upon (hemostasis <10 min), absence of pain or symptoms of irreversible pulpitis, periapical region normal radiographically
Exclusion: traumatized teeth, pulp necrosis or no pulp exposure upon complete caries removal, severe tooth structure loss that required a post retained restoration, and uncontrolled periodontal disease
