Methods	RCT, parallel‐arm Teeth randomly assigned Conducted in the Department of Pedodontics, Faculty of Dentistry, Turkey. Operator was the principal investigator
Participants	40 children, 40 teeth, mean age 7.3 years, age range 5 to 9 years
Interventions	Group 1:Pulpotomy (CH cement/Dycal); n = 20 (1 visit) Rubber dam Caries removal prior to pulpal access Pulp access with high‐speed followed by slow‐speed and varbide burs For haemostasis, moist cotton pellet Solutions rinsed with saline CH cement (Dycal) applied to the exposure site with bal‐ended instruments, followed by glass ionomer cement liner before being restored with amalgam Group 2:Pulpotomy (calcium sulphate hemihydrate/Dentogen); n = 20 (1 visit) Rubber dam Caries removal prior to pulpal access Pulp access with high‐speed followed by slow‐speed and varbide burs For haemostasis, moist cotton pellet Solutions rinsed with saline calcium sulphate hemihydrate (Dentogen) applied to the exposure site with ball‐ended instruments, followed by glass ionomer cement liner before being restored with amalgam
Outcomes	Clinical success (no pathologic mobility, fistula, spontaneous pain, sensitivity to percussion/palpation, oedema), radiographic success (no external root resorption, internal root resorption, inter‐radicular radiolucency, periapical radiolucency), inter‐radicular radiolucency, external root resorption, internal root resorption, fistula, pathologic mobility, spontaneous pain: evaluation at 1, 3, 6, 9 and 12 months (at tooth level).
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Insufficient information to make a clear judgement
Allocation concealment (selection bias)	Unclear risk	Insufficient information to make a clear judgement
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Insufficient information to make a clear judgement
Blinding of clinical outcomes assessment	Low risk	Quote: "...all clinical... recall examinations were performed by the same clinician who was blinded to the treatment groups"
Blinding of radiological outcomes assessment	Low risk	Quote: "...all... radiographic recall examinations were performed by the same clinician who was blinded to the treatment groups"
Incomplete outcome data (attrition bias) All outcomes	Low risk	No missing data
Selective reporting (reporting bias)	Unclear risk	Insufficient information to make a clear judgement
