Methods	RCT, parallel‐arm Teeth randomly assigned Conducted in the paediatric dentistry undergraduate student's clinic of the Hebrew University‐Hadassah School of Dental Medicine, Israel Operators were the Israeli authors of this study
Participants	72 children, 96 teeth, mean age 7.5 years, age range 4.5 to 10 years
Interventions	Group 1:Pulpotomy (formocresol); n = 38 (1 visit) Rubber dam Caries removal prior to pulpal access Pulp access with high‐speed bur Pulpotomy amputation with slow‐speed bur For haemostasis, moistened cotton pellet with saline No irrigation Cotton wool pellet soaked with FC placed on pulp stumps for 5 minutes after pulpotomy, followed by ZOE and IRM before being restored with stainless‐steel crowns Group 2:Pulpotomy (ferric sulphate); n = 58 (1 visit) Rubber dam Caries removal prior to pulpal access Pulp access with high‐speed bur Pulpotomy amputation with slow‐speed bur For haemostasis, moistened cotton pellet with saline No irrigation 15.5% FS solution applied after pulpotomy for 10 or 15 seconds. The FS was then flushed from the pulp chamber with a copious amount of water, followed by ZOE and IRM before being restored with stainless‐steel crowns
Outcomes	Radiographic success (internal root resorption, furcation radiolucency or periapical bone destruction), furcal radiolucency, periapical radiolucency, internal root resorption, pulp canal obliteration, faster root resorption compared with contralateral, slower root resorption compared with contralateral, similar root resorption compared with contralateral: evaluation at 20.5: (6 to 11), (12 to 23) and (24 to 35) months (at tooth level) Signs of failure (internal root resorption, furcation radiolucency, periapical bone destruction, pain, swelling, or sinus tract): evaluation at 20.5 (24 to 35) months (at tooth level)

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Coin toss
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	Unclear risk	Insufficient information to make a clear judgement
Blinding of radiological outcomes assessment	Unclear risk	Insufficient information to make a clear judgement
Incomplete outcome data (attrition bias) All outcomes	Low risk	Proportion of missing outcomes < 10% of children randomly assigned
Selective reporting (reporting bias)	Unclear risk	Insufficient information to make a clear judgement
